A nurse is caring for a 65-year-old male client in a cardiac clinic. The client was recently discharged from an acute hospital stay for worsening heart failure. Below are the exhibits related to the client’s condition:
Exhibit 1: Nurses’ Notes 2 Weeks Ago
The client was admitted to the hospital two weeks ago with worsening heart failure. He was experiencing significant shortness of breath, fatigue, and 2+ edema on bilateral lower extremities. Upon auscultation, an S3 heart sound was noted, and occasional expiratory wheezing was present. The client was managed with furosemide, captopril, and metoprolol at home, but these medications were not sufficient to control his symptoms.
Exhibit 2: Nurses’ Notes Today
The client reports some improvement in shortness of breath with exertion but continues to feel fatigued. Upon auscultation, an S3 heart sound is still noted, and lung sounds are clear. The client has 1+ edema on the ankles and reports nausea, constipation, and blurred vision.
Exhibit 3: History and Physical
The client was discharged from the hospital two days ago after being treated for worsening heart failure. During the hospitalization, he was prescribed digoxin and a potassium supplement in addition to his existing medications. The client will return to the office in two weeks to review lab work and medication management.
Exhibit 4: Laboratory Results Today
- Digoxin: 2.2 ng/mL (0.8 to 2 ng/mL)
- Potassium: 4.8 mEq/L (3.5 to 5 mEq/L)
Exhibit 5: Vital Signs Today
- Temperature: 36.8°C (98.2°F)
- Heart rate: 55/min
- Respiratory rate: 16/min
- Blood pressure: 110/80 mm Hg
- Oxygen saturation: 96% on room air

being treated for worsening heart failure
an S3 heart sound was noted, and occasional expiratory wheezing was present
The Correct Answer is ["A","B","C","E"]
The findings that indicate the client may be experiencing digoxin toxicity are:
- Digoxin level: 2.2 ng/mL (above the therapeutic range of 0.8 to 2 ng/mL)
- Heart rate: 55/min (bradycardia, which can be a sign of digoxin toxicity)
- Nausea
- Blurred vision
These symptoms and lab results are consistent with digoxin toxicity.

Correct Answer is B
Explanation
Choice A rationale
Decreased excretion of urine sodium is not an expected therapeutic effect of bumetanide. Bumetanide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle, leading to increased excretion of sodium and water.
Choice B rationale
Increased urinary output is the expected therapeutic effect of bumetanide. As a potent loop diuretic, bumetanide increases the excretion of water and electrolytes, which helps reduce fluid accumulation in conditions like ascites.
Choice C rationale
Decreased serum glucose is not associated with bumetanide. Bumetanide primarily affects fluid and electrolyte balance and does not have a significant impact on blood glucose levels.
Choice D rationale
Increased blood pressure is not an expected effect of bumetanide. On the contrary, bumetanide can help lower blood pressure by reducing fluid volume and decreasing the workload on the heart.
Correct Answer is A
Explanation
Choice A rationale
Naloxone is an opioid antagonist that rapidly reverses the effects of opioid overdose, including respiratory depression. It binds to opioid receptors and displaces the opioid molecules, reversing their effects.
Choice B rationale
Bisacodyl is a stimulant laxative used to treat constipation. It does not have any effect on opioid-induced respiratory depression.
Choice C rationale
Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepines, not opioids. It is not effective in treating opioid-induced respiratory depression.
Choice D rationale
Pentazocine is an opioid agonist-antagonist used for pain relief. It does not reverse opioid-induced respiratory depression and can potentially worsen the condition.
