NCLEX Question of the Day – Wednesday, June 03, 2026

Today’s question targets early recognition of medication-related complications in a real bedside setting. This matters because nurses are often the first to notice when a treatment is helping, harming, or suddenly becoming unsafe. The skill here is not just remembering a side effect. It is connecting assessment findings to the medication and acting before the patient declines.

Clinical Scenario

A 72-year-old man is admitted to a medical-surgical unit with worsening shortness of breath and bilateral lower-leg edema related to heart failure. His history includes chronic atrial fibrillation, hypertension, and stage 3 chronic kidney disease. Morning medications include furosemide, lisinopril, and digoxin. During the 1000 assessment, the nurse notes that the patient says, “I feel sick to my stomach, and my breakfast tasted strange.” He also reports seeing “yellow-green halos” around the room light. His apical pulse is 54/min and irregular. Morning lab results show potassium 3.0 mEq/L and creatinine 1.8 mg/dL.

The Question

Which action should the nurse take first?

Answer Choices

1. A. Administer the scheduled digoxin and recheck the apical pulse in 1 hour
2. B. Hold the digoxin dose and notify the provider of suspected digoxin toxicity
3. C. Encourage oral fluids to reduce the medication concentration in the bloodstream
4. D. Place the patient flat in bed and administer oxygen at 2 L/min by nasal cannula

Correct Answer

B. Hold the digoxin dose and notify the provider of suspected digoxin toxicity

Detailed Rationale

This patient is showing several classic signs that point to digoxin toxicity. The nurse should recognize the pattern, stop the next dose, and escalate care.

Start with the assessment clues. The patient has nausea, visual changes, and bradycardia. Those are not random findings. They fit digoxin toxicity very well. The yellow-green halos are especially important because visual disturbances are a known warning sign. The apical pulse of 54/min also matters. Digoxin slows conduction through the heart. If the rate is already low, giving more can worsen bradycardia or trigger dangerous dysrhythmias.

The lab values strengthen the concern. The potassium is 3.0 mEq/L, which is low. Low potassium increases the effects of digoxin at the cellular level, making toxicity more likely even if the dose was prescribed correctly. The creatinine is elevated, and the patient has chronic kidney disease. Digoxin is cleared through the kidneys, so reduced renal function can allow the drug to build up.

The first nursing action is to hold the medication. This prevents adding to the problem. Then the nurse should notify the provider promptly and report the specific findings: nausea, visual halos, apical pulse 54/min and irregular, low potassium, and impaired kidney function. These details matter because they explain why the nurse suspects toxicity and help the provider decide the next steps.

After that, the nurse should continue focused assessment and monitoring. This includes checking a full set of vital signs, placing the patient on cardiac monitoring if not already in place, and watching for worsening dysrhythmias such as heart block, ventricular ectopy, or severe bradycardia. The nurse should also anticipate provider orders such as a serum digoxin level, repeat electrolytes, and potassium replacement if appropriate. In more severe cases, digoxin immune Fab may be considered, but that decision comes after provider evaluation and depends on the severity of symptoms and rhythm changes.

The key point is that the nurse does not need to wait for a digoxin level before acting. NCLEX questions often test whether you can identify urgent signs from the bedside assessment. In real practice, the patient’s symptoms and pulse are enough to justify holding the dose and calling the provider.

Why the Other Options Are Wrong

A. Administer the scheduled digoxin and recheck the apical pulse in 1 hour

This is unsafe. The patient already has strong signs of toxicity and an apical pulse below the usual hold parameter of 60/min. Waiting an hour after giving the dose could allow the toxicity to worsen. Reassessment is important, but not after administering a medication that may already be causing harm.

C. Encourage oral fluids to reduce the medication concentration in the bloodstream

This sounds simple, but it does not address the immediate risk. Oral fluids do not quickly or reliably correct digoxin toxicity. Also, this patient has heart failure, so pushing fluids without a clear order may worsen volume overload. The problem is not dehydration. The problem is probable medication toxicity, worsened by low potassium and reduced kidney clearance.

D. Place the patient flat in bed and administer oxygen at 2 L/min by nasal cannula

This does not address the priority problem. There is no evidence here that the patient is in acute respiratory distress. Placing a heart failure patient flat may even make breathing less comfortable. Oxygen is not the first intervention for medication toxicity unless there is a clear oxygenation issue. The real priority is to stop the offending drug and report the findings.

Key Takeaways

• Digoxin toxicity can show up as nausea, poor appetite, visual changes, confusion, bradycardia, and dysrhythmias.
• Low potassium makes digoxin more dangerous because it increases the drug’s effect on the heart.
• Kidney impairment raises toxicity risk because digoxin is cleared renally.
• If the apical pulse is below 60/min, hold digoxin and assess further.
• Do not wait for a lab result if the bedside findings already suggest toxicity.

• What you’d do on shift: Check the apical pulse before giving digoxin.
• Review potassium and renal function before administration when available.
• Ask about nausea, appetite changes, and visual symptoms.
• Hold the dose for bradycardia or suspected toxicity.
• Notify the provider with clear, specific assessment data.
• Monitor rhythm and be ready for follow-up orders.

Quick Practice Extension

1. A patient taking digoxin has an apical pulse of 62/min, potassium of 3.1 mEq/L, and no symptoms. What additional assessment or action would most help the nurse decide whether the medication is safe to give?

2. A patient with suspected digoxin toxicity becomes confused and develops frequent premature ventricular contractions. What should the nurse prioritize monitoring next, and why?
