Correct Answer: D

Rationale: The correct instruction for a client prescribed Losartan is to monitor for signs of dehydration. Losartan can lead to dehydration, so it is essential for the client to be vigilant for symptoms such as dry mouth, increased thirst, and decreased urine output. Providing this instruction ensures the client's safety and helps in early identification of any potential issues related to dehydration.

Correct Answer: B

Rationale: The presence of red blood cells in the urine is a significant finding that can indicate nephrotoxicity, a potential adverse effect of gentamicin. Nephrotoxicity can lead to kidney damage, and monitoring for this adverse reaction is crucial during gentamicin therapy.

Correct Answer: D

Rationale: The correct answer is 'Orthostatic hypotension.' Amitriptyline can lead to orthostatic hypotension, a sudden drop in blood pressure when standing up, which can cause dizziness and increase the risk of falls. It is crucial for the nurse to monitor the client for signs of orthostatic hypotension, such as dizziness or lightheadedness when changing positions, and to educate the client to move slowly when transitioning from lying or sitting to standing.

Correct Answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen.

Correct Answer: C

Rationale: Ezetimibe is contraindicated in clients with active moderate-to-severe liver disorders, particularly if they are already on a statin like simvastatin. Hepatitis C is a liver condition that can be exacerbated by Ezetimibe, leading to potential complications. Therefore, the nurse should identify active hepatitis C as a contraindication to adding Ezetimibe to the client's medications.
