Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. The nurse should first assess the client's chest pain, then administer nitroglycerin if indicated for suspected cardiac origin. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart. This can alleviate chest pain associated with angina or myocardial infarction. Administering morphine or aspirin should come after nitroglycerin if needed. Performing an ECG is important but should not delay immediate treatment with nitroglycerin for chest pain of cardiac origin.

Correct Answer: A

Rationale: Correct Answer: A - Administer antiemetics Rationale: The priority nursing action for a client vomiting post-surgery is to administer antiemetics to control nausea and vomiting, preventing complications like dehydration and electrolyte imbalance. Antiemetics help the client feel more comfortable and promote recovery. Administering fluids (choices B and C) is important, but addressing the vomiting itself takes precedence. Pain relief (choice D) is essential, but not the priority in this case.

Correct Answer: D

Rationale: The correct answer is D: Objective. During a physical assessment, the nurse gathers data through observation and measurement, such as vital signs and physical appearance, which are objective and measurable. This type of data is based on facts rather than opinions or interpretations, making it reliable for assessing the client's health status. Patient-centered data (A) refers to information focused on the client's perspective, subjective data (B) is based on the client's symptoms or feelings, and unconfirmed data (C) lacks validation or evidence, making them unreliable for making clinical decisions.

Correct Answer: A

Rationale: The correct first step is to administer pain relief (Choice A) because addressing the client's pain is a top priority to ensure their comfort and well-being. Pain management is crucial post-surgery to prevent complications and aid in recovery. Monitoring vital signs (Choice B) is important but should follow pain relief to ensure the client's stability. Assessing the wound (Choice C) is necessary but not the immediate priority when the client is in acute pain. Applying a warm compress (Choice D) may provide temporary relief but does not address the underlying cause of the pain. Therefore, administering pain relief is the most appropriate initial action to alleviate the client's discomfort and start the healing process effectively.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. In shock, the priority nursing action is to restore intravascular volume to improve tissue perfusion. IV fluids help increase blood pressure and cardiac output, addressing the underlying cause of shock. Monitoring vital signs (B) is important but administering fluids takes precedence. Administering fluids (C) is a general term and does not specify the urgency of IV fluids. Administering blood transfusion (D) may be indicated in certain types of shock but is not the initial priority.
