A nurse in a provider's office is reviewing the laboratory results of four clients who take digoxin.
Which of the following clients is at risk for developing digoxin toxicity?
A client who takes glyburide for type 2 diabetes mellitus.
A client who takes furosemide for hypertension.
A client who takes cimetidine to reduce gastric acid secretion.
A client who takes azelastine for allergic rhinitis.
The Correct Answer is B
Choice A rationale:
A client who takes glyburide for type 2 diabetes mellitus is not at significant risk for developing digoxin toxicity. Glyburide is an antidiabetic medication and does not interact directly with digoxin.
Choice B rationale: Furosemide, a loop diuretic, can cause electrolyte imbalances such as hypokalemia (normal potassium levels: 3.5 to 5.0 mEq/L) and hypomagnesemia (normal magnesium levels: 1.7 to 2.2 mg/dL). These imbalances increase the sensitivity to digoxin and the risk of toxicity. Digoxin toxicity is associated with symptoms like nausea, vomiting, and arrhythmias. Furosemide's impact on electrolytes makes it a significant risk factor for digoxin toxicity.
Choice C rationale: Cimetidine, a histamine H2 receptor antagonist, can inhibit the metabolism of certain drugs by affecting liver enzymes. However, it does not significantly alter digoxin levels or increase the risk of toxicity. Normal liver enzyme levels include ALT (7 to 56 U/L) and AST (10 to 40 U/L). While cimetidine may interact with other medications, its effect on digoxin is minimal.
Choice D rationale:
A client who takes azelastine for allergic rhinitis is not at significant risk for developing digoxin toxicity. Azelastine is an antihistamine and does not interact directly with digoxin.

Correct Answer is A
Explanation
Choice A rationale:
The nurse should prioritize collecting data from a client who reports unilateral calf pain when ambulating. This symptom could indicate the presence of a deep vein thrombosis (DVT), a potentially life-threatening condition. DVT occurs when a blood clot forms in a deep vein, often in the lower extremities. If left untreated, the clot can dislodge and travel to the lungs, causing a pulmonary embolism. Immediate assessment is crucial to rule out DVT and provide appropriate interventions. The nurse should assess the client's calf for swelling, redness, warmth, and tenderness and may also order diagnostic tests like a duplex ultrasound.
Choice B rationale:
Taking a telephone prescription for a client being transferred from the PACU is important but not the top priority in this situation. While timely transfer and adequate post-operative care are essential, addressing a client with unilateral calf pain and the potential for a DVT takes precedence due to the risk of a life-threatening complication.
Choice C rationale:
Reassuring the partner of a client who sustained a closed head injury is a compassionate action but should not be the first priority. The partner's emotional support can be provided once the immediate medical concerns have been addressed.
Choice D rationale:
Reinforcing a client's dressing on an above-the-knee amputation surgical site is important for the client's post-operative care, but it is not the highest priority when compared to the possibility of a DVT. The nurse should address the client's calf pain first and then attend to the dressing reinforcement.
Correct Answer is C
Explanation
The correct answer is choice C. Monitor the client for black, tarry stools.
Choice A rationale:
Administering clopidogrel with each meal is not necessary. Clopidogrel can be taken with or without food. The primary concern with clopidogrel is its potential to cause bleeding, so monitoring for signs of bleeding is more critical.
Choice B rationale:
Having suction equipment at the bedside is not specifically required for clients taking clopidogrel. This action is more relevant for clients at risk of airway obstruction or those undergoing procedures that might require suctioning.
Choice C rationale:
Monitoring the client for black, tarry stools is essential because it can indicate gastrointestinal bleeding, a known side effect of clopidogrel. This medication increases the risk of bleeding, so observing for signs of internal bleeding, such as melena (black, tarry stools), is crucial.
Choice D rationale:
Initiating contact precautions is not necessary for clients taking clopidogrel. Contact precautions are typically used to prevent the spread of infections, not for managing clients on antiplatelet therapy.
By understanding these rationales, the nurse can ensure the safe administration and monitoring of clopidogrel therapy.
