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) Dry, non-productive cough: One of the most common side effects associated with ACE inhibitors is a dry, non-productive cough. This occurs due to the accumulation of bradykinin, a peptide that can increase in the body when ACE is inhibited. Nurses should assess for this symptom, as it may require changing the medication if it becomes bothersome to the client.
B) Nausea and vomiting: While nausea and vomiting can occur with various medications, they are not specific or common side effects of ACE inhibitors. If these symptoms do arise, they may be due to other factors and should be investigated further.
C) Hypokalemia and vomiting: ACE inhibitors are more commonly associated with hyperkalemia (elevated potassium levels) rather than hypokalemia. Monitoring potassium levels is important, but vomiting is not a typical side effect of ACE inhibitors.
D) Epistaxis and headache: Although headaches can occur with many medications, epistaxis (nosebleeds) is not a common side effect associated with ACE inhibitors. While headache assessment is appropriate, the dry cough is the more characteristic and important symptom to monitor in clients on these medications.
Correct Answer is C
Explanation
A) "Acts on the beta cells within the heart and lungs to regulate cardiac rhythm.": This statement is incorrect because calcium channel blockers do not primarily act on beta cells. Instead, they block calcium channels in cardiac and smooth muscle, which affects heart contractility and conductivity.
B) "Increases heart rate and increases myocardial contractility.": Calcium channel blockers typically do the opposite; they decrease heart rate and myocardial contractility by inhibiting calcium entry into the heart muscle cells. Therefore, this statement does not accurately describe their mechanism of action.
C) "Reduces the contractility and conductivity of the heart.": This statement accurately reflects the action of calcium channel blockers. By blocking calcium entry, these medications decrease myocardial contractility and slow down electrical conduction through the heart, which can help manage dysrhythmias.
D) "Increase oxygen to the systemic circulation.": While calcium channel blockers can improve blood flow and reduce myocardial oxygen demand by decreasing heart workload, their primary action does not directly focus on increasing oxygen delivery to systemic circulation. Their primary role is in managing heart contractility and rhythm.
