Correct Answer: A

Rationale: The correct answer is A: Immobilize the spine. This is the most appropriate intervention for a client with a suspected spinal cord injury to prevent further damage. Immobilization helps stabilize the spine and reduce the risk of spinal cord compression or injury. Administering pain relief (B) or IV fluids (C) should only be done after proper spinal immobilization to avoid exacerbating the injury. Placing the client in a supine position (D) can be beneficial if done carefully after spine immobilization, but immobilizing the spine takes precedence to prevent any potential movement that could worsen the injury.

Correct Answer: D

Rationale: The correct answer is D: cirrhosis. Cirrhosis leads to impaired liver function, causing the liver to be unable to effectively metabolize ammonia, leading to high ammonia levels in the blood. Renal failure (choice A) is associated with high creatinine levels, not ammonia. Psoriasis (choice B) is a skin condition unrelated to ammonia levels. Lupus (choice C) is an autoimmune disease affecting various organs, not directly linked to high ammonia levels. In summary, cirrhosis is the only condition among the options that directly impacts liver function and can lead to high ammonia levels in the blood.

Correct Answer: D

Rationale: The correct answer is D: Urologist consult. This is the appropriate intervention for a client with suspected genitourinary trauma and visible blood at the urethral meatus because a urologist is an expert in diagnosing and managing issues related to the genitourinary system. They can perform a thorough evaluation, order appropriate tests (such as imaging studies), and provide the necessary treatment for any potential trauma. Option A (Insert a Foley catheter) could worsen the trauma if there is an underlying injury. Option B (In and out catheter specimen) and Option C (Voided urine specimen) focus on specimen collection and do not address the potential trauma, making them inappropriate interventions in this situation. Consulting a urologist ensures proper assessment and management of the suspected genitourinary trauma.

Correct Answer: A

Rationale: The correct answer is A: Administer antiepileptics. Administering antiepileptics is the priority nursing action for a client with a history of seizures to prevent seizure recurrence. Antiepileptics help control and manage seizure activity effectively. Monitoring vital signs (B) and placing the client in a lateral position (C) are important actions during a seizure but are not the priority over administering antiepileptics. Providing seizure precautions (D) is also important but does not directly address the immediate need of administering antiepileptics to prevent a seizure.

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.
