1. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

A. Take the medication with an antacid.
B. Avoid dairy products while taking this medication.
C. Expect your stools to turn black.
D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

2. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?

A. PT
B. INR
C. aPTT
D. Platelet count

Correct answer: C

Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.

3. A client has a new prescription for Losartan. Which of the following client statements indicates an understanding of the teaching?

A. I will increase my intake of potassium-rich foods.
B. I will take the medication with a full glass of milk.
C. I should monitor my blood pressure weekly.
D. I will take the medication every other day.

Correct answer: C

Rationale: The correct answer is C: 'I should monitor my blood pressure weekly.' Monitoring blood pressure regularly is crucial for clients taking Losartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. This medication works to dilate blood vessels, lowering blood pressure, so monitoring is essential to assess its effectiveness. Choices A, B, and D are incorrect because increasing potassium-rich foods can be harmful due to the potassium-sparing effect of Losartan, taking the medication with milk is not recommended, and adherence to the prescribed daily dosing schedule is necessary for optimal therapeutic outcomes.

4. What is the expected outcome of Valproate therapy?

A. Decreased fever
B. Decreased sense of anxiety
C. Decreased blood pressure
D. Decreased seizure activity

Correct answer: D

Rationale: The correct answer is D: Decreased seizure activity. Valproate is commonly used in the treatment of epilepsy to help control and reduce seizure frequency. Choices A, B, and C are incorrect because Valproate is not primarily used to treat fever, anxiety, or blood pressure issues.

5. A patient on a medical-surgical unit administers a hypnotic medication to an older adult client at 2100. The next morning, the client is drowsy and wants to sleep instead of eating breakfast. Which of the following factors should the nurse identify as a possible reason for the client's drowsiness?

A. Reduced cardiac function
B. First-pass effect
C. Reduced hepatic function
D. Increased gastric motility

Correct answer: C

Rationale: In older adults, reduced hepatic function can lead to prolonged effects of medications metabolized by the liver. This prolonged effect may result in drowsiness the next morning. Adjusting the dosage of the hypnotic medication may be necessary for this client. Choices A, B, and D are incorrect. Reduced cardiac function (Choice A) is not typically associated with drowsiness due to medication effects. The first-pass effect (Choice B) relates to the initial metabolism of a drug in the liver before reaching systemic circulation, which is not directly linked to drowsiness the next morning. Increased gastric motility (Choice D) does not commonly cause drowsiness as described in the scenario.
