Correct Answer: B

Rationale: Tachycardia and low blood pressure are indicative of worsening dehydration in a patient. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased intravascular volume, while low blood pressure reflects inadequate perfusion due to decreased fluid levels. Bradycardia and shallow respirations are not typical findings in worsening dehydration, and clear lung sounds do not directly correlate with the severity of dehydration.

Correct Answer: A

Rationale: When a task is assigned that is outside the scope of a nursing assistant, it is essential for the assistant to refuse the task and report it to the charge nurse. This ensures that tasks are appropriately delegated, maintaining patient safety and adherence to professional standards. Performing the task without reporting can lead to potential risks for the patient and legal implications. Asking another nurse to perform the task may not address the issue of improper delegation. Accepting the task but documenting it later does not resolve the immediate concern of working within the assistant's scope of practice and seeking appropriate delegation.

Correct Answer: B

Rationale: Correct answer: Before administering morphine sulfate, the nurse should monitor for respiratory depression as it is a significant side effect of this medication. Assessing for pain relief (Choice A) is important but not a pre-administration assessment. Checking the infusion site for complications (Choice C) is relevant for IV medications, not specifically for morphine sulfate. Increasing the dosage if the client reports more pain (Choice D) is not appropriate without further assessment and medical orders.

Correct Answer: B

Rationale: The correct answer is to place the patient on NPO (nothing by mouth) status. Patients recovering from a stroke with difficulty swallowing are at high risk for aspiration, which can lead to serious complications like aspiration pneumonia. Therefore, the priority is to keep the patient on NPO until a thorough evaluation by a healthcare provider is completed. Choice A is incorrect as feeding the patient soft solids can increase the risk of aspiration. Choice C is incorrect as providing ice chips may further compromise swallowing safety. Choice D is incorrect as starting the patient on a clear liquid diet can also increase the risk of aspiration in this scenario.

Correct Answer: C

Rationale: The correct answer is to encourage the patient to reduce sodium intake. The Dietary Approaches to Stop Hypertension (DASH) diet emphasizes reducing sodium intake to help manage hypertension. While increasing fruits and vegetables (Choice A) is important in the DASH diet, reducing sodium intake is considered more crucial. Limiting saturated fats (Choice B) is beneficial but not as critical as reducing sodium. Avoiding caffeine (Choice D) is not a specific recommendation of the DASH diet for managing hypertension.
