Question

A nurse is teaching a client who is to begin chemotherapy about a peripherally inserted central catheter (PICC). Which of the following statements should the nurse include in the teaching?

Answer 1

Correct Answers:

“We can draw blood samples from the PICC for diagnostic tests."

Rationale :

🟠A peripherally inserted central catheter (PICC) provides long-term venous access for therapies such as chemotherapy, antibiotics, or parenteral nutrition.

🟠Blood samples can be safely drawn from a PICC line, reducing the need for repeated peripheral venipuncture and preserving fragile peripheral veins.

🟠The catheter tip is placed in the superior vena cava, allowing for both infusion of vesicant drugs and withdrawal of blood without damaging smaller veins.

🟠Sterile technique and proper flushing protocols are essential when drawing blood from a PICC to prevent infection and maintain catheter patency.

🟠This teaching reduces client anxiety by explaining that routine lab work can be done through the PICC, making treatment less invasive.

Answer 2

Correct Answers:

Use a bed alarm.

Rationale :

🟢Clients with dementia and wandering behaviors are at high risk for falls and injuries due to impaired judgment and disorientation.

🟢A bed alarm provides an early warning when the client attempts to leave the bed unassisted, allowing staff to intervene promptly.

🟢This intervention is a safety measure that does not restrict mobility or autonomy, unlike restraints, and promotes dignity in dementia care.

🟢Bed alarms are part of a fall-prevention protocol widely used in medical-surgical units, especially for high-risk populations such as elderly clients with cognitive impairment.

🟢By ensuring early detection of movement, the nurse can redirect and reorient the client, preventing accidents while maintaining a therapeutic environment.

Answer 3

Correct Answers

Restrict the client's fluid Intake to 2 L per day. [ Anticipated ]
Weigh the client daily. [ Anticipated ]
Increase the dosage of furosemide. [ Anticipated ]
Begin a 24-hr urine collection for the client. [ Nonessential ]
Hold the client's metoprolol. [ Contraindicated ]
Decrease the client's oxygen to 1 L/min via nasal cannula. [ Contraindicated ]

Rationale :

Restrict fluids to 2 L/day

💧The client shows acute fluid overload—a weight increase of 1.8 kg (≈1.8 L) in 24 hr indicates retained volume that strains the heart.

💧A 2-L/day restriction directly reduces intravascular volume and preload, easing ventricular stretch and improving pulmonary congestion.

💧The trend to SpO₂ 90% on 2 L/min suggests fluid-related gas-exchange impairment; limiting fluids helps improve oxygenation by decreasing interstitial/alveolar fluid.

💧Elevated BNP 400 pg/mL confirms ventricular volume/pressure overload, supporting the need for strict fluid control.

💧Fluid restriction is a core heart-failure order aligned with guideline-based care to prevent further edema, dyspnea, and rehospitalization.

Daily weights

💧 Daily weights are the most sensitive indicator of fluid status; a rapid change reflects volume shifts long before exam findings do.

💧 The client’s +1.8 kg in 24 hr signals ~1.8 L retained—actionable data for titrating diuretics and fluids.

💧 Weighing same scale, time, and clothing provides reliable trend data to evaluate response to therapy.

💧Objective weight trends help the team anticipate decompensation and intervene early, reducing risk of pulmonary edema and falls from dyspnea.

💧 In HF pathways, daily weights are a high-priority safety measure and an essential discharge-teaching point to detect relapse.

Increase furosemide dose

💧 Furosemide (loop diuretic) promotes rapid diuresis, lowering preload and relieving pulmonary/interstitial fluid that’s driving the SpO₂ decline.

💧The combination of rising weight, SpO₂ 90% on 2 L, and elevated BNP indicates the current dose is insufficient for present congestion.

💧Augmenting the dose helps reduce dyspnea, crackles, and edema, improving gas exchange and cardiac efficiency.

💧The client’s K⁺ 3.8 mEq/L and concurrent KCl supplementation support safe up-titration with continued electrolyte/renal monitoring.

💧Timely escalation of diuretics is evidence-based HF management, often preventing progression to acute decompensated HF.

Correct Answers

Blank 1 Correct Option: Meningitis
Blank 2 Correct Option: Initiate neurological checks 2hr and Decrease environmental stimuli.
Blank 3 Correct Option: Temperature and Lactate level.

Rationale :

Condition: Meningitis

⏺️The cluster of high fever (39.2 °C/102.6 °F), persistent severe headache (7/10), photophobia, and positive nuchal rigidity are hallmark signs of meningeal inflammation.

⏺️The client’s lethargy and malaise signal central nervous system involvement and possible evolving encephalopathy.

⏺️Tachycardia (115/min) with relative hypotension (98/64 mm Hg) fits a systemic inflammatory response that can accompany infectious meningitis.

⏺️The note “awaiting CT” aligns with standard workup to exclude mass effect before lumbar puncture when meningitis is suspected.

⏺️Early recognition of infectious meningitis is critical because rapid progression to raised ICP, seizures, and septic shock can occur without prompt, targeted management.

Actions

Initiate neurological checks 2 hr

⏺️Frequent neuro checks trend level of consciousness, orientation, pupils, and motor response, enabling early detection of rising ICP or neurologic decline.

⏺️Meningitis can deteriorate rapidly, so q2-hr monitoring of GCS, pupils, strength, and new focal deficits provides actionable changes for escalation.

⏺️Trending findings guides timely interventions (e.g., airway protection, anticonvulsants, hyperosmolar therapy) to prevent secondary brain injury.

⏺️Establishing a baseline and documenting serial changes improves team communication and decision-making for diagnostics and treatments.

⏺️Close surveillance also helps evaluate the response to therapy (antimicrobials/fluids) and the emergence of complications such as seizures.

Decrease environmental stimuli

⏺️ Photophobia and phonophobia are common; darkened, quiet rooms directly reduce headache and meningeal irritation.

⏺️Lowering stimuli limits sympathetic surges (tachycardia/blood pressure spikes) that can increase cerebral metabolic demand and ICP.

⏺️Minimizing interruptions and clustering care support rest, improving comfort without sedatives that could mask neuro changes.

⏺️ Reducing agitation diminishes Valsalva-like responses (cough/strain) that transiently raise intracranial pressure.

⏺️Environmental control is an immediate, low-risk intervention that supports analgesia and other definitive treatments.

Parameters

Temperature

⏺️ Fever is a core marker of infectious activity; trending temperature assesses treatment effectiveness once antimicrobials are initiated.

⏺️ Persistent hyperthermia increases cerebral metabolic rate, potentially worsening ICP and neurological outcomes.

⏺️ Regular monitoring guides antipyretic use and cooling strategies, balancing comfort with cerebral protection.

⏺️Temperature trends correlate with other markers (e.g., WBC, hemodynamics), informing ongoing sepsis surveillance.

⏺️Documenting response (defervescence vs. spikes) helps differentiate therapeutic success from treatment failure or complications.

Lactate level

⏺️ Serum lactate reflects tissue hypoperfusion and the severity of sepsis, a frequent complication of bacterial meningitis.

⏺️Elevated lactate (>2 mmol/L) indicates anaerobic metabolism and correlates with worse outcomes, prompting aggressive resuscitation.

⏺️Serial lactate trends assess response to IV fluids and antibiotics, confirming improving perfusion or signaling deterioration.

⏺️Integrating lactate with vital signs and mental status provides a comprehensive view of global perfusion and neurologic risk.

⏺️ Early normalization of lactate supports effective source control and guides titration of hemodynamic support if needed.

Correct Answers

Blank 1 Correct Option: Hyperthyroidism
Blank 2 Correct Option: Initiate hydration therapy and Place client on telemetry.
Blank 3 Correct Option: Neurological Status and Cardiac dysrhythmias.

Rationale :

Condition: Hyperthyroidism

🔷 Markedly elevated T3 (310 ng/dL) and T4 (25 mcg/dL) with suppressed TSH (0.1 mU/mL) are diagnostic for hyperthyroidism, matching the client’s hypermetabolic presentation.

🔷 The constellation of fever, tachycardia/palpitations, hypertension, tremor, nervousness/insomnia, diarrhea, and weight loss despite good appetite are classic thyrotoxicosis findings.

🔷 Recent infection (influenza) is a well-known trigger that can precipitate thyroid storm, explaining the acute worsening over hours.

🔷 Hypoxemia (SpO₂ 89%) with crackles and tachypnea reflects increased oxygen demand and cardiac workload driven by excess thyroid hormone, risking cardiopulmonary decompensation.

🔷 Prompt recognition is essential because untreated thyroid storm can rapidly progress to arrhythmias, heart failure, hyperthermia, delirium, and shock; early targeted management reduces morbidity and mortality.

Actions

Initiate Hydration Therapy

🔷 Severe insensible losses from fever/diaphoresis plus gastrointestinal losses from diarrhea create intravascular volume depletion in hyperthyroidism.

🔷 Isotonic IV fluids restore preload and tissue perfusion, supporting delivery of oxygen to meet the elevated metabolic rate.

🔷 Adequate hydration helps protect renal function and facilitates clearance of catabolic by-products generated by the hypermetabolic state.

🔷 Volume repletion reduces the risk of lactic acidosis and shock, stabilizing hemodynamics while other definitive therapies (e.g., beta-blockade/antithyroid agents) are initiated.

🔷 Careful, titrated fluid administration is necessary given crackles/possible congestion; the goal is euvolemia with frequent reassessment of lungs, vitals, and urine output.

Place Client on Telemetry

🔷 Excess thyroid hormone increases β-adrenergic activity, predisposing to atrial fibrillation, SVT, and other cardiac dysrhythmias—a leading cause of deterioration in thyroid storm.

🔷 Continuous telemetry enables immediate detection of rate/rhythm changes, guiding timely beta-blocker titration or advanced interventions if instability occurs.

🔷 The client’s HR 125/min, palpitations, and chest pain indicate high arrhythmic risk and potential myocardial oxygen supply-demand mismatch.

🔷 Telemetry trend data (e.g., rate response to therapy, recurrence of ectopy) provides objective feedback on treatment effectiveness.

🔷 Coupled with strict vital-sign surveillance, telemetry improves early recognition of hemodynamic compromise and prevents unexpected cardiac events.

Parameters

Cardiac Dysrhythmias

🔷 Thyrotoxicosis is strongly associated with atrial fibrillation and rapid ventricular responses, which can precipitate hypotension, ischemia, or heart failure.

🔷 Continuous rhythm assessment verifies rate control and identifies conversion or worsening that might require urgent management.

🔷 Monitoring allows correlation of fever control, hydration, and beta-blockade with improvements in heart rate variability and rhythm stability.

🔷 Early detection of new ischemic changes or QT abnormalities reduces risk of ventricular arrhythmias.

🔷 Documenting dysrhythmia trends informs decisions about escalation, such as antiarrhythmic therapy or higher-level care.

Neurological Status

🔷 Agitation, anxiety, and insomnia can evolve into delirium, seizures, or coma in thyroid storm, reflecting worsening cerebral metabolic stress.

🔷 Serial assessments of LOC, orientation, pupils, and behavior track response to therapy and signal impending crisis requiring rapid intervention.

🔷 Neurologic monitoring complements temperature and hemodynamic data to gauge overall systemic control of the hypermetabolic state.

🔷 Worsening neuro signs may indicate hyperthermia, hypoxemia, or hypoperfusion, prompting reassessment of oxygenation, fluids, and medications.

🔷 Clear documentation of neuro trends enhances interprofessional communication and guides safe sedation/analgesia choices that won’t mask deterioration.

Answer 7

Correct Answers

Blank 1 Correct Option: Upper GI bleed
Blank 2 Correct Option: Test stools for occult blood.
Blank 3 Correct Option: Hemoglobin & hematocrit and Blood pressure.

Rationale :

Condition: Upper GI Bleed

🔶 The combination of coffee-ground emesis over two days followed by a large bright-red hematemesis (~1 cup) strongly indicates an active upper GI source (stomach or proximal duodenum).

🔶 Hypotension (89/52) with sinus tachycardia (115/min) and lethargy/dizziness signals volume depletion from acute blood loss, consistent with ongoing hemorrhage.

🔶 The low Hgb 9 g/dL and Hct 27% confirm significant blood-loss anemia, aligning with clinical signs of hypoperfusion (weak peripheral pulses).

🔶 Risk factors—chronic alcohol intake and smoking—increase the likelihood of peptic ulcer disease and gastritis, common causes of upper GI bleeding.

🔶 Hyperactive bowel sounds with abdominal tenderness further support a GI process, while clear lungs and adequate oxygenation point away from primary respiratory causes and focus attention on hemodynamic compromise from GI loss.

Action:

Test Stools for Occult Blood

🔶 Fecal occult blood testing (FOBT) detects ongoing or intermittent bleeding that may not be clinically visible, providing crucial data after an episode of hematemesis.

🔶 Serial positive occult tests indicate continued blood loss, prompting urgent escalation (e.g., endoscopy, transfusion strategy).

🔶 FOBT helps corroborate trends in Hgb/Hct, offering a low-risk, bedside adjunct to gauge whether bleeding is active, diminishing, or rebleeding.

🔶 In a patient with mixed emesis patterns (digested and fresh blood), stool testing refines the picture of total GI blood loss burden beyond what is seen in emesis alone.

🔶 Early documentation of occult bleeding supports timely GI consult and guides resuscitation targets while definitive therapy is arranged.

Parameters:

Hemoglobin & Hematocrit

🔶 Serial Hgb/Hct are the primary laboratory indicators for the severity and trajectory of acute GI hemorrhage.

🔶 Downward trends despite resuscitation signal ongoing bleeding and the need for more aggressive intervention (e.g., transfusion, endoscopic hemostasis).

🔶 Trending every 4–6 hours aligns with best practices for acute bleeding, allowing timely adjustments to fluids, blood products, and pharmacotherapy.

🔶 Coupling Hgb/Hct with clinical status (mental state, urine output, vitals) provides a comprehensive index of perfusion.

🔶 Stabilization or rise in values after treatment indicates hemostasis and effective resuscitation, supporting step-down in intensity of monitoring.

Blood Pressure

🔶 Systolic hypotension and narrowed pulse pressure in acute GI bleeding reflect decreased circulating volume and risk of shock.

🔶 Frequent BP checks (and continuous monitoring if available) detect hemodynamic instability early, guiding fluid boluses and transfusion thresholds.

🔶 A falling BP with a compensatory rise in HR indicates ongoing hemorrhage and the need for urgent escalation (rapid GI evaluation, vasoactive support if required).

🔶 BP trends, integrated with orthostatic measurements, help quantify volume responsiveness and resuscitation adequacy.

🔶 Stabilization of BP alongside symptom improvement (less dizziness, stronger pulses) marks resuscitative success while awaiting definitive hemostasis.

Answer 9

Correct Answers:

Serum ammonia

Rationale :

🟢In advanced liver disease, the liver loses its ability to convert ammonia into urea for excretion.

🟢Elevated serum ammonia leads to hepatic encephalopathy, causing confusion, altered LOC, and even coma.

🟢Monitoring ammonia levels helps evaluate the progression of encephalopathy and the effectiveness of therapies such as lactulose.

🟢Other labs (e.g., LFTs, PT/INR, albumin) are also monitored, but ammonia directly reflects neurotoxicity risk.

🟢Prompt recognition of elevated ammonia prevents irreversible neurologic injury.

Correct Order:

Order : 1 : No answer text available
Order : 2 : No answer text available
Order : 3 : No answer text available
Order : 4 : No answer text available

Rationale :

Check the client’s airway and level of consciousness

🔷 In DKA, ABCs come first—severe metabolic acidosis and fatigue can depress mental status and threaten airway protection.

🔷 Assessing LOC (e.g., AVPU/GCS) verifies the client can maintain the airway, manage secretions, and protect against aspiration.

🔷 Kussmaul respirations may be present as a compensatory response; confirming airway patency and effective ventilation is essential before other measures.

🔷 Early airway assessment guides the urgency for oxygen support and potential airway escalation if the client deteriorates.

🔷 Prioritizing airway/LOC prevents secondary hypoxia, which worsens lactic acidosis and overall instability.

Assess vital signs to determine hydration status

🔷 DKA produces osmotic diuresis (polyuria), causing hypovolemia with tachycardia, hypotension, and poor perfusion—vital signs show its severity.

🔷 A full set (HR, BP, RR, SpO₂, temperature) plus orthostatic changes clarifies the volume deficit and the immediacy of resuscitation needs.

🔷 Identifying shock physiology guides fluid type, rate, and monitoring plan, preventing under- or over-resuscitation.

🔷 Baseline vitals provide a reference to evaluate the client’s response to therapy in the next steps.

🔷 Accurate hydration assessment reduces risks like renal hypoperfusion and electrolyte derangements that compound DKA.

Administer prescribed IV fluids

🔷 Isotonic crystalloids (e.g., 0.9% NS) are first-line to restore intravascular volume, improve tissue perfusion, and begin lowering serum glucose via dilution and improved renal clearance.

🔷 Early fluids blunt counter-regulatory hormones, enhance insulin sensitivity, and help correct the hyperosmolar state.

🔷 Volume repletion protects the kidneys, improves lactate clearance, and prepares for insulin initiation (often started after initial fluid bolus).

🔷 Fluid therapy also helps correct electrolyte shifts—particularly potassium, which must be watched closely as acidosis resolves.

🔷 Titration is guided by hemodynamics, urine output (≥0.5 mL/kg/hr), mental status, and serial labs to achieve euvolemia without overload.

Monitor for pulmonary edema

🔷 After aggressive fluids, clients—especially those with older age, renal impairment, or cardiac disease—are at risk for fluid overload.

🔷 Continuous reassessment of lung sounds (crackles), work of breathing, SpO₂, JVD, and daily weights detects early pulmonary congestion.

🔷 Watching for rising oxygen needs or new dyspnea prompts immediate adjustment of fluid rates and consideration of diuretics if indicated.

🔷 Careful balance prevents trading hypovolemia for cardiopulmonary compromise, a common pitfall in rapid resuscitation.

🔷 Integrating clinical findings with I&O and chest exam trends ensures safe progression from resuscitation to definitive metabolic management.
