NCLEX Question of the Day – Sunday, May 31, 2026

Today’s question targets Pharmacology, with a focus on spotting a dangerous medication effect early and responding in the right order. This matters in real nursing because medication complications can move fast. A nurse who recognizes the pattern, checks the right data, and acts promptly can prevent a patient from getting much worse.

Clinical Scenario

A 72-year-old patient is on a medical-surgical unit for treatment of community-acquired pneumonia. He has a history of heart failure, chronic kidney disease stage 3, and atrial fibrillation. His scheduled medications include furosemide, lisinopril, and digoxin. During morning rounds, the nurse notes that the patient says, “My stomach feels off, and my breakfast tastes strange.” He also reports seeing “yellow halos” around the ceiling lights. The apical pulse is 52/min and irregular. Overnight urine output was adequate, but the morning basic metabolic panel shows a potassium level of 3.0 mEq/L.

The Question

Which action should the nurse take first?

Answer Choices

1. Administer the scheduled digoxin and recheck the heart rate in 1 hour.
2. Hold the digoxin dose and notify the provider of the findings.
3. Give the prescribed furosemide to improve cardiac output.
4. Encourage the patient to eat breakfast before taking morning medications.

Correct Answer

B. Hold the digoxin dose and notify the provider of the findings.

Detailed Rationale

This patient is showing several classic signs of digoxin toxicity. The key clues are nausea, visual changes described as yellow halos, bradycardia, and a low potassium level. Put together, these findings point to a medication problem that needs immediate nursing action.

The first nursing priority is to withhold the digoxin. Digoxin slows conduction through the heart. In a patient whose apical pulse is already 52/min and irregular, giving the medication could worsen bradycardia or trigger a more serious dysrhythmia. On the NCLEX, when a medication is likely causing harm, the safe first step is often to stop and reassess before giving more.

The next step is to notify the provider with the important data already gathered. This includes the apical pulse, rhythm change, symptoms, potassium level, kidney history, and current medications. That matters because digoxin is cleared by the kidneys. When kidney function is reduced, the drug can build up more easily. This patient also takes furosemide, which can lower potassium. Low potassium increases the risk of digoxin toxicity because it makes the heart more sensitive to the drug.

The nurse should also continue focused assessment. Check the full set of vital signs. Confirm the apical pulse for a full minute. Review the medication administration record for recent doses. Look for other symptoms such as weakness, confusion, dizziness, or worsening arrhythmias. If available by prescription or protocol, the provider may order a serum digoxin level, repeat electrolytes, and a 12-lead ECG.

Monitoring is a major part of the response. The nurse should watch for worsening bradycardia, new ectopy, atrioventricular block, or signs of decreased cardiac output such as hypotension, fatigue, or altered mental status. Potassium replacement may be ordered, but the nurse should not independently give anything that is not prescribed. In severe toxicity, antidote treatment may be needed, but that decision comes from the provider based on the full clinical picture.

The deeper lesson is this: do not focus on one symptom alone. Nausea by itself could seem minor. A slow pulse by itself could be baseline. But when you cluster the findings together, the pattern becomes dangerous. Safe nursing care depends on seeing the whole picture.

Why the Other Options Are Wrong

A. Administer the scheduled digoxin and recheck the heart rate in 1 hour.

This is unsafe. The patient already has warning signs of toxicity and a low apical pulse. Rechecking later delays action and may allow the patient’s condition to worsen. If a drug is likely causing harm now, the nurse should not give the next dose.

C. Give the prescribed furosemide to improve cardiac output.

This is the wrong priority and may make the problem worse. Furosemide can lower potassium further. Since hypokalemia increases the risk of digoxin toxicity, giving it without addressing the current findings could worsen arrhythmias. “Improve cardiac output” sounds reasonable, but NCLEX questions often test whether you notice when a routine medication becomes unsafe in a specific moment.

D. Encourage the patient to eat breakfast before taking morning medications.

This does not address the urgent issue. Food will not fix bradycardia, visual changes, or possible toxicity. Delaying the real intervention while focusing on comfort or routine is not safe when assessment data point to a high-risk medication effect.

Key Takeaways

• Digoxin toxicity can show up as nausea, vomiting, poor appetite, visual changes, confusion, and bradycardia.
• Low potassium raises the risk of digoxin toxicity because it increases the drug’s effects on the heart.
• Reduced kidney function matters because digoxin is cleared by the kidneys and can accumulate.
• Before giving digoxin, assess the apical pulse for 1 full minute and review relevant labs if available.
• If toxicity is suspected, hold the dose, assess closely, and notify the provider with clear, specific data.

• On-shift mini-checklist:
• Check apical pulse for 1 full minute.
• Ask about nausea, appetite changes, vision changes, and dizziness.
• Review potassium level and kidney function trends.
• Hold digoxin if findings are concerning.
• Notify the provider and continue cardiac monitoring.

Quick Practice Extension

1. A patient taking digoxin has an apical pulse of 58/min but no symptoms. What additional assessment data would help you decide the safest next step?
2. A patient on digoxin and a loop diuretic develops new weakness and skipped beats. Which lab values would you review first, and why?

One strong NCLEX habit is learning to connect the medication, the lab, and the assessment finding. In this case, digoxin + hypokalemia + bradycardia is not a routine morning pass. It is a warning sign that should change the nurse’s plan right away.
