Correct Answer: D

Rationale: Prasugrel is a platelet inhibitor, which increases the risk of bleeding. Monitoring for bleeding, particularly at the catheterization site and in other areas, is the most important assessment following administration of the drug. Checking platelet count and observing urine color are relevant but not as immediate. Reviewing liver function tests is not directly related to the adverse effects of prasugrel.

Correct Answer: A

Rationale: The correct answer is to monitor the client's electrolyte levels. When a client is receiving IV fluids for dehydration, it is crucial to assess their electrolyte levels regularly. Dehydration can lead to imbalances in electrolytes, especially sodium and potassium, which are essential for maintaining fluid balance and proper organ function. Checking urine output (Choice B) is important but not as critical as monitoring electrolyte levels. Assessing skin turgor (Choice C) is an indirect method of assessing dehydration but does not provide specific information about electrolyte imbalances. Monitoring blood pressure (Choice D) is important but not the most critical assessment in this scenario as electrolyte imbalances can have a more direct impact on the client's condition.

Correct Answer: A

Rationale: The correct answer is A: 'Monitor the client's hemoglobin and hematocrit.' When a client with chronic kidney disease is prescribed erythropoietin, the nurse's priority action is to monitor the client's hemoglobin and hematocrit. Erythropoietin stimulates red blood cell production, so monitoring these lab values helps evaluate the effectiveness of erythropoietin in treating anemia. Monitoring the client's blood pressure (choice B) is important but not the priority in this scenario. Assessing the client for signs of infection (choice C) is important but not the priority related to the prescription of erythropoietin. Monitoring the client for signs of bleeding (choice D) is relevant but not the priority action when erythropoietin is prescribed.

Correct Answer: C

Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.

Correct Answer: B

Rationale: The correct answer is to redirect the client to a quiet activity. This intervention helps reduce agitation and aggression in clients with Alzheimer's disease by providing a distraction and promoting a calming environment. Reassuring the client and providing emotional support (Choice A) can be beneficial but is not the priority in this situation. Administering a PRN dose of lorazepam (Choice C) should not be the first intervention due to the risk of adverse effects and should only be considered if other non-pharmacological interventions are ineffective. Applying restraints (Choice D) should be avoided unless absolutely necessary for the client's safety as it can lead to further distress and is not the initial priority intervention.
