Correct Answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea, dizziness, and paresthesias. When a client is anxious, they may hyperventilate, leading to respiratory alkalosis. Tachypnea (rapid breathing) is a common sign of respiratory alkalosis. Dizziness and paresthesias (tingling or numbness in the extremities) are also typical symptoms. Choices A, B, and D are incorrect. Disorientation and dyspnea (Choice A) are not specific signs of respiratory alkalosis. Drowsiness, headache, and tachypnea (Choice B) may be more indicative of other conditions. Dysrhythmias and decreased respiratory rate and depth (Choice D) are not consistent with the expected signs of respiratory alkalosis.

Correct Answer: D

Rationale: The correct answer is D: 'Complaints of feeling sweaty.' Scopolamine, an anticholinergic medication, commonly causes the side effect of decreased sweating, not increased urine output or pupil constriction. While dry mouth is a possible side effect, it is less likely than the altered sweating pattern. Therefore, the nurse should monitor the client for complaints of feeling sweaty due to the potential side effect of decreased sweating associated with scopolamine.

Correct Answer: B

Rationale: Assessing blood pressure is the priority assessment when working with a population of African-American clients due to the high prevalence of hypertension in this group. African Americans have a higher risk of hypertension, which can lead to complications like end-stage renal disease. Monitoring blood pressure allows for the early detection and management of hypertension. While measuring height and weight, observing for signs of abuse, and asking about medications are important assessments, assessing blood pressure is crucial in this context to address the specific health needs of African-American clients.

Correct Answer: A

Rationale: The correct answer is A. Furosemide (Lasix) is a loop diuretic used to manage fluid overload and hypertension in clients with CKD. Monitoring daily weights is crucial as weight changes reflect fluid status. Each kilogram of weight change approximately corresponds to 1 liter of fluid retention or loss, making it essential for evaluating the medication's effectiveness. Auscultating heart and breath sounds is more relevant for heart failure cases with fluid retention, not specifically for assessing the effect of furosemide in CKD. Palpating the abdomen is not a direct indicator of furosemide's effectiveness; instead, assessing for edema would be appropriate. While assessing the client's diet history is important to monitor electrolyte balance due to potassium loss with furosemide, it does not directly evaluate the medication's efficacy.
