Correct Answer: A

Rationale: The correct answer is A. Ibuprofen can increase the risk of bleeding when taken with warfarin, as both medications affect clotting. The client should use alternative pain relievers like acetaminophen. Choice B is correct as using an electric razor is a safe choice to prevent cuts that could lead to bleeding. Choice C is correct as warfarin interacts with vitamin K found in leafy green vegetables. Choice D is correct as regular blood level checks are necessary to monitor the effects and adjust the warfarin dosage if needed.

Correct Answer: C

Rationale: Choice C is the most appropriate response because it encourages the mother to express her feelings and explore the reasons behind her guilt. This approach allows the mother to process her emotions effectively and address her grief. Choices A and B do not directly address the mother's feelings of guilt and may not help her work through her emotions. Choice D acknowledges the mother's emotional state but does not delve into the underlying issues causing her guilt and grief.

Correct Answer: C

Rationale: Offering to go for a walk with the client helps redirect their energy in a non-confrontational way, avoiding escalation of aggressive behavior while promoting de-escalation.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease often develop anemia due to reduced erythropoietin production, leading to decreased red blood cell production. Iron supplementation is frequently required to enhance red blood cell production. Choices B, C, and D are incorrect because in chronic kidney disease, there is a need to restrict phosphorus intake, control carbohydrate intake for blood sugar management, and monitor electrolytes and fluid balance rather than blood glucose levels.

Correct Answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.
