Correct Answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

Correct Answer: C

Rationale: The correct answer is a low-sodium diet. Patients with chronic kidney disease are often advised to follow a low-sodium diet to help manage fluid retention. Excessive sodium intake can lead to fluid buildup in the body, causing complications for individuals with kidney issues. Choices A and B are incorrect because while protein intake may need to be monitored in kidney disease, the primary focus is typically on sodium restriction. Choice D is incorrect as a high-sodium diet would exacerbate fluid retention in patients with chronic kidney disease.

Correct Answer: D

Rationale: The correct answer is D because a blood pressure drop or other signs of morphine overdose should be reported, especially when using a PCA pump. Choices A, B, and C are within normal limits and do not indicate an immediate concern related to morphine administration.

Correct Answer: A

Rationale: Encouraging compliance through education is crucial in helping patients understand the importance of consistent medication use. By providing education, the patient can make informed decisions about their health and better manage their condition. Contacting the healthcare provider (choice B) may be necessary in some cases, but the initial approach should focus on patient education. Documenting the refusal (choice C) is important for legal and medical records but does not address the root cause of non-compliance. Exploring alternative treatment options (choice D) should come after efforts to educate and encourage compliance with the current medication regimen.
