Correct Answer: D

Rationale: The correct instruction for self-administration of enoxaparin is to inject it into the fat tissue of the abdomen for proper absorption. Choice A is incorrect as enoxaparin should not be injected into the muscle. Choice B is unnecessary for enoxaparin administration. Choice C is incorrect as rubbing the injection site after administering the medication is not recommended.

Correct Answer: A

Rationale: Priming the IV tubing with 0.9% sodium chloride is crucial before administering packed RBCs as it prevents hemolysis and ensures the safe transfusion of blood. Using a smaller 20- to 22-gauge IV catheter is recommended for packed RBCs to prevent hemolysis due to the small tubing size and faster flow rate. Obtaining filterless IV tubing is incorrect as blood products should be administered through a specialized filter to prevent potential clots or contaminants from reaching the patient. Placing blood in the warmer for an hour is unnecessary and could lead to overheating, potentially causing harm to the patient.

Correct Answer: D

Rationale: The correct answer is D. Black, tarry stools can indicate gastrointestinal bleeding, a serious adverse effect of warfarin that requires immediate medical attention. Option A is incorrect because while bruising is a common side effect of warfarin, it is not limited to the elbows. Option B is incorrect as a red rash is not a typical adverse effect of warfarin. Option C is also incorrect because developing a cough is not a reason to discontinue warfarin unless advised by a healthcare provider.

Correct Answer: C

Rationale: The correct answer is C: "I should remain upright for at least 30 minutes after taking this medication." This statement indicates understanding because clients taking alendronate should remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Choice A is incorrect because alendronate should be taken with a full glass of water after waking up, not before breakfast. Choice B is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because alendronate should be taken separately from antacids.

Correct Answer: D

Rationale: Placing the client's left arm on a pillow while they are sitting helps prevent shoulder displacement and provides support for the limb post-stroke. This positioning is important to maintain proper alignment and prevent complications. Choices A, B, and C are incorrect because placing food on the left side of the mouth, providing total assistance with ADLs, and maintaining the client on bed rest do not directly address the specific needs related to unilateral paralysis and dysphagia post right hemispheric stroke.
