Question

A patient with Acute Kidney Injury (AKI) has a serum potassium level of 7.0 mEq/L. You should plan which actions as a priority in caring for this patient? (Select all that apply.)

Answer 1

Correct Answers:

Place the patient on a cardiac monitor
Review the patient’s medications to determine if any contain or retain potassium

Rationale :

Place the patient on a cardiac monitor

⚡ A potassium level of 7.0 mEq/L is severe hyperkalemia, which is a life-threatening emergency requiring immediate nursing action.

⚡ Hyperkalemia disrupts the heart’s electrical conduction, placing the patient at high risk for lethal dysrhythmias such as ventricular fibrillation or asystole.

⚡ Continuous cardiac monitoring allows early detection of ECG changes like peaked T waves, widened QRS, or heart block.

⚡ Monitoring enables the nurse to quickly respond to any rhythm deterioration while awaiting treatment orders.

⚡ It also helps assess the effectiveness of emergency therapies like IV calcium, insulin-dextrose, or bicarbonate.

Review the patient’s medications to determine if any contain or retain potassium

(Correct — Safety Intervention)

📝 AKI reduces the kidneys’ ability to excrete potassium, increasing the risk of dangerous potassium accumulation.

📝 The nurse must review all medications for agents that raise potassium, including ACE inhibitors, ARBs, spironolactone, potassium supplements, NSAIDs, trimethoprim, and heparin.

📝 Holding these medications prevents further increases in serum potassium levels.

📝 Medication review is a critical step in preventing worsening hyperkalemia.

📝 Early identification of potassium-retaining drugs supports safe, effective management and reduces complications.

Notify the healthcare provider (HCP)

(Correct — Time-Critical)

📞 A potassium level of 7.0 mEq/L is a critical lab value requiring immediate reporting.

📞 The provider must initiate urgent interventions such as IV calcium gluconate, insulin with dextrose, beta-agonists, sodium bicarbonate, or emergency dialysis.

📞 Timely reporting ensures the patient receives life-saving treatment before arrhythmias occur.

📞 The nurse should report accompanying findings such as urine output, ECG abnormalities, or symptoms.

📞 Rapid communication is essential to prevent cardiac arrest and stabilize the patient’s condition.

❌ Incorrect Answers

Make the patient NPO except for ice chips

(Incorrect — Not relevant to hyperkalemia emergency)

🚫 NPO status does not lower potassium and is not part of hyperkalemia treatment.

🚫 Hyperkalemia requires immediate cardiac protection and potassium-lowering measures, not food restriction.

🚫 AKI dietary management involves low-potassium meals, not complete NPO.

🚫 NPO may delay necessary treatments such as oral potassium binders if ordered.

Allow an extra 500 mL of intravenous fluid to dilute the electrolyte concentration

(Incorrect — Unsafe in AKI)

❌ Giving excess fluids does not effectively dilute potassium during a hyperkalemic crisis.

❌ In AKI, additional IV fluids can cause fluid overload, pulmonary edema, and worsening kidney stress.

❌ Fluid must be given only if carefully prescribed—not to “dilute” electrolytes.

❌ This intervention can worsen the patient's condition rather than help it.

Answer 2

Correct Answers:

Weight gain
Cola-colored urine
Increased BUN

Rationale :

Weight gain

💧 Fluid retention is a hallmark of acute glomerulonephritis because the inflamed glomeruli cannot filter fluids normally.

💧 This leads to edema, especially in the face, hands, and lower extremities.

💧 Reduced kidney filtration causes sodium and water to accumulate, producing rapid weight gain in a short period.

💧 Monitoring daily weights helps track fluid status and detect worsening kidney function.

💧 Sudden weight increase is often one of the first noticeable signs of glomerular injury.

Cola-colored urine

🟤 Cola-colored or tea-colored urine occurs due to hematuria, a classic sign of glomerulonephritis.

🟤 Inflamed glomeruli allow red blood cells to leak into the urine.

🟤 The darker color results from RBC breakdown, giving urine a brown or smoky appearance.

🟤 This finding differentiates glomerulonephritis from conditions like cystitis or dehydration.

🟤 The presence of protein and RBCs together often confirms glomerular inflammation.

Increased BUN

🔼 Glomerulonephritis impairs the kidneys’ ability to excrete nitrogenous wastes.

🔼 As filtration decreases, BUN rises, indicating worsening kidney function.

🔼 Elevated BUN often appears along with increased creatinine, reflecting acute renal impairment.

🔼 Rising BUN can also correlate with symptoms like nausea, fatigue, and malaise.

🔼 Monitoring labs helps assess the severity and progression of the renal injury.

❌ Incorrect Options

Increased urine output

❌ Glomerulonephritis typically causes oliguria (low urine output), not increased output.

❌ Reduced filtration from glomerular inflammation leads to fluid retention rather than excess urination.

Hypotension

❌ Patients usually present with hypertension, not hypotension.

❌ Fluid retention and decreased kidney function raise blood pressure rather than lower it.

Answer 3

Correct Answers:

Assess for mental status changes and place on seizure precautions.

Rationale :

🧠 A sodium level of 115 mEq/L indicates severe hyponatremia, which can cause cerebral edema as water shifts into brain cells.

🧠 This places the patient at high risk for confusion, restlessness, decreased level of consciousness, and seizures.

🧠 The priority nursing role is to closely assess neurological status and immediately initiate seizure precautions (padded rails, suction, oxygen available, bed in low position).

🧠 Early recognition of mental status changes allows prompt intervention if the condition worsens and prevents injury during possible seizures.

🧠 This option directly addresses the most life-threatening complication of severe hyponatremia: neurological deterioration and seizures.

🔴Rapidly administer vasopressin (ADH) ❌

🚫 Vasopressin (ADH) causes the kidneys to retain free water, which would further dilute serum sodium and worsen hyponatremia.

🚫 Giving ADH in a patient who already has critically low sodium increases the risk of brain swelling and herniation.

🚫 Vasopressin is sometimes used for diabetes insipidus, where the problem is excessive water loss—not for dilutional hyponatremia.

🚫 This option does not treat the cause; it makes the sodium level drop even further, increasing danger.

🔴 Administer 10% saline solution IVPB ❌ (not the nurse’s independent FIRST move)

💉 Hypertonic saline (3% or sometimes 7.5%) is the usual treatment for severe symptomatic hyponatremia—not typically 10% saline, and never started independently by the nurse.

💉 Hypertonic solutions must be given very carefully, usually via a central line, with strict provider orders and close monitoring to avoid osmotic demyelination from rapid correction.

💉 Starting a strong hypertonic saline on your own (without orders) is not a safe nursing intervention, even though hypertonic fluids can be part of the medical treatment plan.

💉 The safer priority nursing response from the answers given is to monitor neuro status and implement seizure precautions while awaiting specific fluid orders from the provider (Option C).

🔴Encourage fluids orally ❌

🚱 Encouraging fluids would likely mean giving more free water, which would further dilute sodium and make the hyponatremia worse.

🚱 In severe hyponatremia, especially at 115 mEq/L, fluids are usually restricted, not pushed, unless under very specific orders.

🚱 Increasing water intake can worsen cerebral edema and raise the risk of seizures and brain herniation.

🚱 So this option is contraindicated and unsafe as a primary nursing intervention in this situation.

Answer 4

Correct Answers:

Hgb of 9 g/dL and Hct of 28% on a patient who is receiving a second unit of blood

Rationale :

🩸 A hemoglobin of 9 and hematocrit of 28% are still low, especially in a client currently receiving a second unit of blood—you’d expect improvement.

🩸 Persistently low or dropping values during transfusion may indicate ongoing bleeding, ineffective transfusion, or even a transfusion reaction depending on the trend and clinical picture.

🩸 Because blood transfusion carries risks such as acute hemolytic reaction, volume overload, and respiratory compromise, any concerning lab or clinical sign during transfusion must be addressed immediately.

🩸 The nurse should assess the patient right away (vital signs, symptoms like dyspnea, flank pain, chills) and be prepared to stop the transfusion and notify the provider if indicated.

🩸 Among the options listed, this situation is the one that most likely represents a current, unstable, or evolving problem that could quickly become life-threatening.

🔴 ABG pH 7.35, PaCO₂ 58 for a client diagnosed with COPD ❌

🌬️ In COPD, a chronic elevation of PaCO₂ is common due to long-standing hypoventilation and air trapping in the lungs.

🌬️ The pH 7.35 is at the lower end of normal, indicating the body has compensated for the elevated CO₂ with renal bicarbonate retention.

🌬️ This is an example of chronic compensated respiratory acidosis, which is often baseline for many COPD patients—not an emergency.

🌬️ While the client still needs routine monitoring and long-term management, these ABG values do not require immediate action compared to possible transfusion issues in Option A.

🔴 A patient with a right middle lobe chest tube whose oxygen saturation is 97% ❌

🫁 An oxygen saturation of 97% is normal and indicates that the patient is well oxygenated, even with a chest tube.

🫁 The presence of a chest tube is expected in certain conditions (e.g., pneumothorax, hemothorax, surgery), and good O₂ saturation suggests effective lung re-expansion and gas exchange.

🫁 There is nothing in this data suggesting acute deterioration, respiratory distress, or hypoxia.

🫁 This patient needs ongoing monitoring, but no immediate intervention is required based solely on this information.

🔴 BNP of 100 on a client with stage 4 congestive heart failure ❌

💚 BNP (B-type natriuretic peptide) is a marker used to assess heart failure severity; higher numbers generally indicate more volume overload and ventricular stretch.

💚 A BNP of 100 is relatively low, especially for someone with stage 4 heart failure, where you might expect much higher values when decompensated.

💚 This value may actually indicate that the patient is not currently in severe fluid overload, or that their condition is relatively stable at this moment.

💚 Therefore, while the disease stage is serious, this isolated BNP value does not represent an immediate crisis needing urgent nursing action compared with a possibly problematic transfusion (Option A).

Answer 5

Correct Answers:

Assessment of fluid volume status
Assessing the stoma for perfusion
Assess for skin breakdown around the stoma

Rationale :

Assessment of fluid volume status

💧 An ileostomy drains liquid stool rich in water and electrolytes, putting the patient at high risk for dehydration.

💧 Fluid loss through the stoma may reach 1–2 liters per day, especially in the early postoperative period.

💧 Monitoring for signs of volume depletion—such as tachycardia, dry mucous membranes, low urine output, hypotension—is a priority.

💧 Early fluid assessment helps prevent acute kidney injury, a complication common in new ileostomy patients with excessive output.

💧 Daily weights, intake/output tracking, and electrolyte monitoring are essential components of safe care.

Assessing the stoma for perfusion

❤️ The stoma must be checked frequently to ensure it is well-perfused, meaning healthy blood flow.

❤️ A normal stoma should appear moist, shiny, and red or pink.

❤️ Signs of compromised perfusion—such as dusky, pale, purple, or black coloring—signal ischemia or necrosis, which is a surgical emergency.

❤️ Early detection of perfusion problems ensures timely intervention to prevent stoma failure.

❤️ This is one of the highest priorities immediately after surgery because stoma viability determines long-term function.

Assess for skin breakdown around the stoma

🛡️ Ileostomy output contains digestive enzymes that are very irritating to the skin, leading to rapid breakdown if the skin is exposed.

🛡️ The nurse must check the peristomal skin for redness, erosion, ulceration, or leakage of stool under the appliance.

🛡️ Protecting the skin using proper pouch fitting, barrier films, and skin barriers prevents painful dermatitis and infections.

🛡️ Peristomal skin integrity is critical for patient comfort and long-term appliance adherence.

🛡️ Early detection of irritation promotes healing and reduces complications.

❌ Incorrect Answers

Change the patient’s diet to high residue

🚫 A high-residue diet (high-fiber foods like nuts, seeds, raw veggies) can cause blockages in a new ileostomy.

🚫 Patients with a new ileostomy require a low-fiber, low-residue diet initially to promote healing and prevent obstruction.

🚫 High-residue foods are reintroduced gradually over weeks to months depending on tolerance.

🚫 Therefore, this option is incorrect and unsafe for early post-operative ileostomy care.

Ambulating the patient once after surgery

🚶‍♂️ Encouraging mobility is important, but ambulating only once is inadequate and not a priority for ileostomy-specific risks.

🚶‍♂️ Patients should ambulate early and frequently, not just once, to prevent complications like ileus, DVT, and pneumonia.

🚶‍♂️ While activity is part of post-op care, it is not specific to ileostomy safety and not among the top priorities compared to fluid balance and stoma assessment.

🚫 Therefore, this answer does not meet the level of urgency needed for a new ileostomy patient.

Answer 6

Correct Answers:

Administer IV calcium gluconate, give 25 units of subcutaneous insulin, and 1 amp of D50

Rationale :

⚡ Peaked T waves = severe hyperkalemia, which can progress to ventricular tachycardia, ventricular fibrillation, or asystole.

⚡ IV calcium gluconate stabilizes the cardiac membrane, reducing the risk of lethal arrhythmias within minutes.

⚡ Insulin + D50 shifts potassium into the cells, rapidly lowering serum potassium levels and protecting the myocardium.

⚡ This is the fastest, most effective, life-saving intervention, making it the top priority.

⚡ Dialysis and long-term diet teaching matter—but after the immediate cardiac threat is addressed.

❌ Incorrect Answers

Prepare the patient for dialysis

💧 Dialysis does remove potassium effectively, but it does not act immediately, and the patient might arrest while waiting.

💧 Before dialysis can begin, the patient must be stabilized with IV calcium gluconate to protect the heart.

💧 Therefore, dialysis is appropriate later, but not the priority when peaked T waves are present.

Request an order for PO Kayexalate

🟤 Kayexalate lowers potassium by removing it through the bowel, but onset may take hours.

🟤 It is not useful for emergency hyperkalemia, especially when ECG changes are already present.

🟤 It does not stabilize the myocardium and offers no protection against immediate arrhythmias.

Teach the patient about avoiding foods with high potassium

🍌 Dietary teaching is important for long-term CKD management, but it offers no immediate correction of hyperkalemia.

🍌 Peaked T waves indicate that the patient is in acute danger, and teaching is never done during a life-threatening emergency.

🍌 Education becomes relevant after stabilization, not during ECG instability.

Answer 7

Correct Answers:

Adequate blood flow through pulmonary circulation

Rationale :

🫁 A pulmonary embolism (PE) causes an abrupt blockage of a pulmonary artery, which stops normal blood flow to areas of the lung.

🫁 Even though alveoli may be receiving oxygen, the blood cannot pick it up, leading to a ventilation–perfusion (V/Q) mismatch.

🫁 The core physiological disruption in a PE is impaired perfusion, not ventilation.

🫁 This results in hypoxemia, increased pulmonary vascular resistance, and strain on the right side of the heart.

🫁 Therefore, the primary alteration during a PE is failure of adequate pulmonary blood flow, making option D correct.

❌ Incorrect Answers

A. pH balance in the pulmonary veins and arteries

🚫 Although severe PE can contribute indirectly to respiratory alkalosis (from hyperventilation), this is not the primary alteration.

🚫 PE does not directly cause an acute disruption of arterial/venous pH balance—that is a secondary consequence, not the main physiological disturbance.

🚫 The essential problem is blocked blood flow, not acid–base imbalance.

B. Maintenance of muscle tone in the diaphragm

🚫 A pulmonary embolism does not affect the diaphragm’s muscle tone.

🚫 The diaphragm continues to function normally in PE; the problem lies in blocked circulation, not impaired muscle control.

🚫 Diaphragmatic dysfunction is seen in neuromuscular disorders, not pulmonary embolism.

C. Maintenance of constant osmotic pressure in the alveoli

🚫 Osmotic pressure in the alveoli is largely influenced by fluid balance and capillary permeability—not by blood clots in pulmonary arteries.

🚫 PE does not primarily alter alveolar osmotic forces; alveoli often remain structurally intact and ventilated.

🚫 The mismatch occurs because alveoli have air, but no blood is flowing past them.

Answer 9

Correct Answers:

Laparoscopic cholecystectomy

Rationale :

Laparoscopic cholecystectomy

🟢 This is the gold-standard treatment for symptomatic gallstones and cholecystitis.

🟢 The patient’s symptoms — jaundice, nausea, abdominal bloating, and back pain — indicate obstruction and inflammation, which typically require surgical removal of the gallbladder.

🟢 Laparoscopic cholecystectomy is preferred because it is minimally invasive, has faster recovery, and reduces the risk of complications compared to open surgery.

🟢 It permanently resolves the problem by removing the source of stone formation and inflammation.

🟢 This is the most anticipated and appropriate intervention for cholecystitis due to gallstones.

❌ Incorrect Answers (Elaborated)

Intracorporeal lithotripsy

❌ Typically used for kidney stones, not gallstones.

❌ Not standard therapy for gallbladder disease because gallstones are often multiple, cholesterol-based, and embedded within a diseased gallbladder.

❌ Does not treat inflammation or infection associated with cholecystitis.

Methyl tertiary butyl ether (MTBE) infusion

❌ MTBE is a chemical used for stone dissolution, rarely used today due to toxicity, irritation, and limited success.

❌ It is not recommended for acute cholecystitis.

❌ It does not treat the underlying inflammation or recurrent stone formation.

Extracorporeal shock wave therapy (ESWL)

❌ ESWL is used mainly for renal calculi, not gallstones.

❌ It may be used in highly select gallstone cases, but only when the gallbladder is functional — which is not the case in cholecystitis.

❌ ESWL does not address inflamed or obstructed gallbladders and is not first-line treatment.
