Correct Answer: A

Rationale: The correct answer is A: 'Weigh yourself daily and report a gain of 2 pounds in 24 hours.' Daily weight monitoring is crucial for detecting fluid retention early in clients with heart failure. Reporting a gain of 2 pounds in 24 hours can indicate fluid overload, prompting timely intervention. Choice B is incorrect because increasing fluid intake can exacerbate fluid overload in clients with heart failure. Choice C is incorrect as a high-sodium diet can worsen fluid retention. Choice D is incorrect as vigorous exercise can strain the heart and worsen heart failure symptoms.

Correct Answer: B

Rationale: The best advice the nurse can provide to a client concerned about odor from a new colostomy is to use an odor-proof pouch. This option helps control odors effectively by containing and masking any unpleasant smells. Avoiding high-fiber foods (Choice A) is not the best advice as fiber is essential for bowel health, and decreasing fluid intake (Choice C) can lead to dehydration and other complications. Increasing dairy products in the diet (Choice D) is not directly related to controlling odors from a colostomy.

Correct Answer: A

Rationale: When a postoperative client reports incisional pain and has two prescriptions for PRN analgesia, the nurse should first compare the client's pain scale rating with the prescribed dosing. This action ensures that the client receives the appropriate medication based on their pain level. Determining the onset of action or asking the client to choose the medication does not guarantee that the right medication is administered according to the pain intensity. Documenting the pain report is important but should not be the first action when deciding which medication to administer.

Correct Answer: B

Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.

Correct Answer: C

Rationale: To infuse 150 mL over 90 minutes, the pump should be set to 100 ml/hour (150 mL / 1.5 hours). This rate ensures that the medication is delivered at the proper rate as prescribed. Choices A, B, and D are incorrect because they do not reflect the correct calculation based on the volume of the IV bag and the infusion duration provided in the question.
