Correct Answer: A

Rationale: The correct action for the nurse preparing to administer a controlled substance is to witness the waste of the controlled substance by another nurse. This practice is crucial to prevent misuse and ensure accurate documentation. Choice B is incorrect because disposing of the controlled substance by oneself without proper witnessing is not in accordance with safety protocols. Choice C is incorrect as leaving a controlled substance unattended in a client's room poses risks of diversion or unauthorized access. Choice D is incorrect because documenting the administration and signing off at the end of the shift is important but does not specifically address the issue of witnessing the waste of a controlled substance, which is a critical step in ensuring proper handling and accountability.

Correct Answer: B

Rationale: The correct answer is to 'Use a 7th-grade reading level.' This ensures that the material is accessible to most clients by keeping the language simple and easy to understand. Emphasizing important information using bold lettering (Choice A) can be helpful but may not enhance overall readability. Avoiding cartoons (Choice C) is not a universal rule and can sometimes make the material more engaging. Using words with three or four syllables (Choice D) can make the material difficult to comprehend for many clients.

Correct Answer: C

Rationale: The correct answer is C. A respiratory rate of 10/min indicates respiratory depression, a serious adverse effect of morphine that should be reported immediately. Options A, B, and D are within acceptable ranges and not indicative of life-threatening complications when administering morphine.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration in clients receiving enteral feedings is to elevate the head of the bed during feedings. This position helps prevent regurgitation and aspiration of the feeding. Positioning the client supine (Choice A) increases the risk of aspiration as it promotes reflux. Administering feedings over 10 minutes (Choice B) does not directly reduce the risk of aspiration. Placing the client in a lateral position after feedings (Choice D) does not address the risk of aspiration during the feeding process.

Correct Answer: C

Rationale: The correct answer is C: 'Ensure that the client has a referral for physical therapy.' For a client with left-sided hemiplegia, physical therapy is crucial in restoring function and mobility. It is the nurse's priority to ensure the client receives the necessary rehabilitation services. Consulting with a case manager about insurance coverage (Choice A) is important but not the priority at this stage. Counseling caregivers on respite care options (Choice B) and referring the client to a local stroke support group (Choice D) are also valuable but not as essential as ensuring the client has access to physical therapy for rehabilitation.
