A nurse is assisting with a presentation about caring for clients who are receiving diuretic therapy. The nurse should explain that which of the following medications can put clients at risk for hyperkalemia?
Mannitol
Spironolactone
Hydrochlorothiazide
Furosemide
The Correct Answer is B
A) Mannitol:
Mannitol is an osmotic diuretic that works by increasing the osmotic pressure in the glomerular filtrate, leading to increased urine output. It is not associated with causing hyperkalemia.
B) Spironolactone:
This is the correct choice. Spironolactone is a potassium-sparing diuretic that can put clients at risk for hyperkalemia. It works by blocking the action of aldosterone in the distal tubules of the kidneys, leading to decreased sodium reabsorption and increased potassium retention.
C) Hydrochlorothiazide:
Hydrochlorothiazide is a thiazide diuretic that promotes the excretion of sodium and water and can lead to potassium depletion (hypokalemia) rather than hyperkalemia.
D) Furosemide:
Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption in the ascending loop of Henle. It can lead to potassium depletion (hypokalemia) rather than hyperkalemia.

Correct Answer is B
Explanation
A. Arrange referral for family therapy to deal with home stressors:
While family therapy may be beneficial in addressing underlying issues, suspected abuse must be reported promptly to protect the client's safety. Referral for family therapy can be considered as part of a comprehensive intervention plan but should not delay reporting of suspected abuse.
B. Follow the agency's guidelines for reporting suspected abuse:
Reporting suspected abuse is the first priority when there are concerns about a client's safety. Following the agency's guidelines ensures that the appropriate authorities are notified and that the client receives the necessary protection and support.
C. Check the bruises at the next visit to the client's home:
Delaying action and waiting until the next visit to check the bruises could put the client at further risk of harm. Suspected abuse requires immediate attention, and the nurse should follow established protocols for reporting and intervening in such situations.
D. Institute more frequent visits to the client's home:
While more frequent visits may allow for closer monitoring of the client's condition, suspected abuse should be addressed immediately through appropriate reporting channels. Increasing visit frequency alone may not adequately address the safety concerns and may delay necessary intervention.
Correct Answer is D
Explanation
A. Vomiting:
Vomiting can lead to metabolic alkalosis due to the loss of hydrochloric acid from the stomach, resulting in increased bicarbonate levels in the blood. It does not directly contribute to metabolic acidosis.
B. Hyperventilation:
Hyperventilation can lead to respiratory alkalosis due to excessive elimination of carbon dioxide (CO2) through increased respiratory rate and depth. It is not associated with metabolic acidosis.
C. Diarrhea:
Diarrhea can lead to metabolic acidosis due to the loss of bicarbonate-rich fluid from the gastrointestinal tract, resulting in decreased bicarbonate levels in the blood. While diarrhea can contribute to metabolic acidosis, it is not the case in this scenario.
D. Salicylate intoxication:
Salicylate intoxication, such as aspirin overdose, can lead to metabolic acidosis due to the accumulation of salicylic acid, which is a weak acid that dissociates in the body, contributing to an increased anion gap metabolic acidosis. This is a direct cause of metabolic acidosis in this scenario.
