A client with hypertension and benign prostate hyperplasia is prescribed doxazosin (Cardura). Which of the following statements below would the nurse emphasize regarding doxazosin (Cardura)?
"Increase your potassium intake by eating more bananas and apricots."
"Weigh yourself daily, and report any weight loss to your prescriber."
"The impaired taste associated with this medication usually goes away in 2 to 3 weeks."
"Be sure to lie down after taking the first dose, because first-dose hypotension may make you dizzy."
The Correct Answer is D
A) "Increase your potassium intake by eating more bananas and apricots.": Doxazosin is not a potassium-sparing medication, and there is no specific indication for increased potassium intake with this drug. This advice may be misleading, especially since excessive
potassium can pose risks, particularly in certain populations.
B) "Weigh yourself daily, and report any weight loss to your prescriber.": Daily weighing can be important for monitoring fluid retention in some conditions, but weight loss is not a common side effect of doxazosin. Instead, clients should be more concerned about weight gain due to fluid retention or potential side effects from the medication.
C) "The impaired taste associated with this medication usually goes away in 2 to 3 weeks.": Impaired taste is not a well-documented side effect of doxazosin. While some medications may cause changes in taste, this statement is not relevant for doxazosin and does not address the most critical aspects of its administration.
D) "Be sure to lie down after taking the first dose, because first-dose hypotension may make you dizzy.": This statement is accurate and important. Doxazosin can cause first-dose hypotension, leading to dizziness or fainting. Advising the client to lie down after the first dose helps mitigate the risk of hypotensive effects, making this the most appropriate emphasis for the nurse.

Correct Answer is A
Explanation
A) Hypokalemia: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Since digoxin competes with potassium for binding at the sodium-potassium ATPase site in the heart, low potassium levels can lead to increased digoxin effects and toxicity. Therefore, it is crucial to monitor potassium levels and correct any deficiencies before administering digoxin.
B) Hyperkalemia: While hyperkalemia is a serious concern and can also affect digoxin therapy, it usually results in decreased effectiveness of digoxin rather than increasing toxicity. Elevated potassium levels can diminish the drug's positive inotropic effect.
C) Hypocalcemia: Although calcium levels can influence cardiac function, hypocalcemia is not directly related to digoxin toxicity. Monitoring calcium is important for overall cardiac health, but it is not the primary focus when assessing the risk for digoxin toxicity.
D) Hypernatremia: Elevated sodium levels do not have a direct impact on the efficacy or toxicity of digoxin. While sodium levels are essential to monitor for overall health, they are not critical in the context of digoxin administration and toxicity risk.
Correct Answer is D
Explanation
A. "Depending on the level of your PT/INR, the clot will begin to dissolve.": This response is misleading, as heparin's effect is not primarily monitored by PT/INR; rather, heparin is monitored by activated partial thromboplastin time (aPTT). Moreover, heparin does not directly dissolve clots; it prevents further clot formation.
B. "After the first dose, the clot will begin to dissolve.": This statement inaccurately suggests that heparin has an immediate effect on dissolving existing clots. While heparin acts quickly to inhibit further clotting, it does not lead to the dissolution of clots after the first dose.
C. "It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.": This is not accurate for heparin, which has an immediate effect on coagulation. While the therapeutic effects can be optimized over several days, heparin begins to work right away to prevent further clotting.
D. "Heparin does not dissolve clots. It stops new clots from forming.": This response accurately describes the mechanism of action of heparin. Heparin prevents the extension of existing clots and the formation of new clots, but it does not actively dissolve clots. This clarification is essential for the client’s understanding of their treatment and expectations regarding DVT management.
