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 ["C","D","E","F"]
Explanation
A) Constipation: While constipation can occur with digoxin use, it is not a classic sign of digoxin toxicity. Therefore, it is less critical for the client to monitor this symptom specifically in relation to toxicity.
B) Dark red urine: Dark red urine is not typically associated with digoxin toxicity. This symptom could indicate other conditions, such as blood in the urine or issues with the kidneys, but it is not a direct manifestation of digoxin toxicity.
C) Bradycardia: Digoxin toxicity can lead to bradycardia, characterized by a slower than normal heart rate. The client should be instructed to monitor their pulse and report any significant changes, especially if the heart rate drops below 60 beats per minute.
D) Nausea: Nausea is a common symptom of digoxin toxicity. Clients should be aware of this and report any persistent or severe nausea, as it may indicate that the digoxin levels in their system are too high.
E) Vomiting: Vomiting is another classic sign of digoxin toxicity. Clients should be instructed to report any episodes of vomiting, as this can further complicate their condition and may require adjustment of their medication.
F) Anorexia: Anorexia, or loss of appetite, can also occur with digoxin toxicity. Clients should be advised to monitor their appetite and report any significant changes, as this can be an early indicator of toxicity.
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.
