Question

A nurse is assisting in the care of a female client.

Answer 1

Correct Answers

Blank 1 Correct Option: blood pressure
Blank 2 Correct Option: potassium level

Rationale :

💎 Blood pressure is the nurse’s immediate priority due to the client's significant hypotension (BP dropped from 104/56 to 80/46 mm Hg), which indicates potential hypovolemic shock secondary to ongoing fluid loss from profuse diarrhea.

💎 Hypotension compromises tissue perfusion and oxygen delivery to vital organs, requiring prompt fluid resuscitation and hemodynamic support to prevent organ dysfunction.

💎 After stabilizing blood pressure, the nurse should address the potassium level (3.1 mEq/L), which is below the normal range and can lead to cardiac arrhythmias, muscle weakness, and worsened GI symptoms.

💎 Electrolyte imbalances are common in clients with Clostridium difficile-associated diarrhea due to excessive fluid and electrolyte loss.

💎 Although the elevated temperature and GI findings are important, circulatory collapse and hypokalemia represent the most life-threatening concerns and must be prioritized in nursing care.

Answer 2

Correct Highlights :

short of breath
intercostal retractions
Wheezing auscultated throughout lung fields.
Diffuse, raised rash present on trunk.
Blood pressure 90/55 mm Hg
Respiratory rate 30/min
Oxygen saturation 91% on room air

Rationale :

Shortness of breath

🟥 Shortness of breath is an early and critical sign of respiratory compromise in anaphylaxis.

🟥 It indicates that the client may be experiencing airway narrowing or bronchoconstriction, both of which can lead to hypoxemia if not addressed.

🟥 In allergic reactions, histamine release leads to mucosal edema and bronchial smooth muscle contraction, reducing airflow.

🟥 In the context of a recent antibiotic administration, this symptom should immediately raise concern for a severe allergic response.

🟥 Prompt recognition is essential to prevent respiratory failure and the need for intubation.

Intercostal retractions

🟥 Intercostal retractions are a visible sign of increased work of breathing and typically occur when airway resistance is elevated.

🟥 This finding indicates that the client’s accessory muscles are being recruited due to difficulty moving air through the narrowed airway.

🟥 It is an objective marker of respiratory distress and often precedes respiratory decompensation.

🟥 When paired with wheezing and hypoxia, retractions signal severe bronchospasm or upper airway obstruction, requiring urgent action.

🟥 The nurse must treat this as an emergency sign of worsening respiratory compromise in the setting of suspected anaphylaxis.

Wheezing auscultated throughout lung fields

🟥 Wheezing is caused by airflow through narrowed airways and is a hallmark symptom of bronchospasm, often seen in anaphylaxis and asthma.

🟥 In an allergic reaction, this reflects lower airway involvement, as smooth muscle constriction and mucosal edema limit airflow.

🟥 Widespread wheezing indicates a diffuse reactive airway, which can progress rapidly to complete airway obstruction if not treated.

🟥 This finding confirms that the client is experiencing respiratory involvement beyond just upper airway swelling.

🟥It requires immediate administration of epinephrine, bronchodilators (e.g., albuterol), and oxygen support.

Diffuse, raised rash present on trunk

🟥 A diffuse, raised rash (likely urticaria) indicates systemic histamine release, which is characteristic of type I hypersensitivity reactions.

🟥 While a rash alone may not be life-threatening, its appearance in conjunction with respiratory symptoms and hypotension confirms a multisystem reaction.

🟥 The trunk distribution suggests a generalized reaction, rather than a localized contact dermatitis.

🟥This is a visible indicator of immune system activation, supporting the diagnosis of anaphylaxis.

🟥 The rash may also precede or accompany angioedema, which can rapidly affect the airway, making it a key warning sign.

Blood pressure 90/55 mm Hg

🟥Hypotension is a defining feature of anaphylactic shock, resulting from vasodilation and increased capillary permeability caused by histamine and other mediators.

🟥 A drop in BP from 125/75 to 90/55 is clinically significant and reflects hemodynamic instability.

🟥 Without intervention, this can lead to organ hypoperfusion, shock, and death.

🟥 This drop is especially concerning in the presence of tachycardia, indicating a compensatory response to decreased perfusion.

🟥 The nurse must recognize this as an emergency and anticipate the need for IV fluid resuscitation and epinephrine administration.

Respiratory rate 30/min

🟥 A respiratory rate of 30/min is markedly elevated and indicates the body is attempting to compensate for hypoxia or airway obstruction.

🟥 In anaphylaxis, increased RR reflects the struggle to maintain adequate gas exchange despite bronchospasm or edema.

🟥 This hyperventilation may progress to fatigue and respiratory collapse if the underlying cause is not corrected quickly.

🟥 This is not simply anxiety-related; it is occurring alongside objective signs of airway compromise and oxygen desaturation.

🟥 It warrants immediate respiratory assessment and initiation of high-flow oxygen and emergency medications.

Oxygen saturation 91% on room air

🟥 An SpO₂ of 91% is below the normal threshold (< 94%) and reflects impaired oxygenation, likely due to ventilation-perfusion mismatch from airway inflammation.

🟥 In the context of recent cefdinir administration and allergy history, this drop strongly suggests the lungs are unable to adequately exchange gases.

🟥 This is particularly dangerous when combined with wheezing, increased RR, and retractions, pointing to progressive respiratory failure.

🟥 The nurse should recognize this as an urgent sign of hypoxia requiring immediate supplemental oxygen and epinephrine.

🟥 Persistent hypoxemia can lead to loss of consciousness and cardiac arrest if untreated.

Answer 3

Correct Answers:

“This medication can cause you to feel tired."
"You can take a second dose of this medication at least 2 hours after the initial dose if the headache persists."
"This medication should start to alleviate the headache within 1 hour."
“You might experience a feeling of pressure in your chest after taking this medication."
"Do not take more than 200 milligrams of this medication within 24 hours."
"You should discontinue this medication if pregnancy is planned or suspected."

Rationale :

"This medication can cause you to feel tired."

✳️ Sumatriptan, a serotonin receptor agonist, commonly causes fatigue, drowsiness, or sedation as a side effect.

✳️ Clients should be advised not to drive or operate heavy machinery until they know how the drug affects them.

"You can take a second dose of this medication at least 2 hours after the initial dose if the headache persists."

✳️ Sumatriptan is often taken as a single dose at headache onset, but if symptoms persist, one repeat dose may be taken after at least 2 hours.

✳️ The maximum dose varies depending on the form, but no more than two doses should be taken in 24 hours.

"This medication should start to alleviate the headache within 1 hour."

✳️ Sumatriptan typically begins to relieve migraine symptoms within 30–60 minutes.

✳️ Clients should be informed that prompt relief is expected after taking the dose.

"You might experience a feeling of pressure in your chest after taking this medication."

✳️ A known side effect of sumatriptan is chest discomfort, tightness, or pressure, which mimics cardiac symptoms but is usually non-cardiac in origin.

✳️ However, it should still be evaluated if severe or persistent.

"Do not take more than 200 milligrams of this medication within 24 hours."

✳️ The maximum daily dose of oral sumatriptan is 200 mg.

✳️ Exceeding this dose increases the risk of serious cardiovascular and neurological adverse effects, including serotonin syndrome and vasospasm.

"You should discontinue this medication if pregnancy is planned or suspected."

✳️ Although some studies suggest sumatriptan may be relatively safe in pregnancy, it is classified as Pregnancy Category C in many formularies.

✳️ It is not routinely recommended during pregnancy, and clients should notify their provider if they plan or suspect pregnancy.

Answer 4

Correct Answers:

"Measure your blood glucose levels periodically."

Rationale :

🔵 Prednisone, a corticosteroid, increases glucose metabolism, which can lead to hyperglycemia—even in non-diabetic clients.

🔵 Long-term use especially at high doses can impair glucose tolerance and trigger steroid-induced diabetes.

🔵 Clients should be taught to monitor blood glucose regularly, particularly if they have other risk factors.

🔵 Early detection of elevated glucose levels helps prevent long-term complications such as neuropathy and renal damage.

🔵 The nurse must reinforce this as a critical part of self-care when using prednisone chronically.

Answer 5

Correct Answers:

Increase fluid intake.

Rationale :

💧 Lithium is eliminated through the kidneys, and its levels are directly affected by the body's hydration status.

💧 Insufficient fluid intake can lead to increased lithium reabsorption, placing the client at risk for toxicity.

💧 Signs of lithium toxicity include tremors, confusion, nausea, and in severe cases, seizures or coma.

💧 Clients should maintain a daily fluid intake of 2–3 L, especially during illness, heat, or activity.

💧 Nurses must emphasize hydration as a core safety measure with lithium therapy.

Answer 6

Correct Answers:

Wheezing

Rationale :

🔴 Wheezing indicates a possible hypersensitivity or anaphylactic reaction to sulfasalazine, which requires immediate medical intervention.

🔴 Unlike minor side effects such as nausea or arthralgia, respiratory symptoms signal airway involvement, a life-threatening emergency.

🔴 This may be a sign of bronchospasm or laryngeal edema, which could rapidly progress to respiratory failure.

🔴 Prompt response, such as oxygen support, epinephrine, or antihistamines, may be necessary.

🔴 Nurses must prioritize any airway-compromising symptom above all others.

Answer 7

Correct Answers:

Hepatitis A vaccine

Rationale :

🟢 Clients with chronic liver disease are at higher risk for severe complications if they contract Hepatitis A.

🟢 The Hepatitis A vaccine provides prophylactic protection against liver infection, which could otherwise exacerbate hepatic dysfunction.

🟢 Other choices, like niacin or alprazolam, may cause hepatic injury and are not appropriate for this population.

🟢 The rotavirus vaccine is reserved for infants and not indicated for adults.

🟢 Vaccination helps prevent acute-on-chronic liver failure, a potentially fatal condition.

Answer 8

Correct Answers:

Offer the client a carbohydrate snack.

Rationale :

⏺️Glipizide is an oral antidiabetic agent that increases insulin secretion, lowering blood glucose levels.

⏺️ If mistakenly given to someone who doesn’t need it (e.g., intended was guaifenesin), it may cause dangerous hypoglycemia.

⏺️ Symptoms can develop rapidly, including dizziness, sweating, shakiness, and confusion.

⏺️ Administering a fast-acting carbohydrate such as juice or glucose tabs is the first line of treatment.

⏺️ Immediate correction prevents complications like seizures or loss of consciousness.

Answer 10

Correct Answers:

Firmness

Rationale :

🟠 A positive tuberculin skin test is identified by the presence of induration (firm swelling) at the injection site.

🟠 Redness, ulceration, or bleeding are not diagnostic of a positive result.

🟠 Induration of a certain size (e.g., ≥10 mm) is measured and interpreted based on the client’s risk profile.

🟠 Nurses should use a ruler to measure the diameter and document findings in millimeters.

🟠 Accurate interpretation is crucial for TB detection and prevention.
