Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

Correct Answer: A

Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.

Correct Answer: B

Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.

Correct Answer: A

Rationale: In a scenario where a person is unconscious and there is an indication of a possible heart attack, the immediate priority for the nurse should be to administer cardiac compressions. This action helps maintain circulation and ensures oxygenated blood reaches vital organs until the AED is available. Checking for a pulse or performing rescue breaths may delay essential circulation support, and attaching AED pads should follow the initial step of administering compressions to maximize the chances of a successful resuscitation.

Correct Answer: D

Rationale: The correct answer is D: Tuberculosis. Coughing up blood (hemoptysis) is a key symptom of tuberculosis. Tuberculosis is a respiratory infection caused by the bacterium Mycobacterium tuberculosis. The other options are incorrect because an allergic reaction typically involves symptoms like itching, hives, or swelling, not coughing up blood. Ringworm is a fungal skin infection characterized by a red, circular rash, and systemic lupus erythematosus is an autoimmune disease that primarily affects joints and skin without causing hemoptysis.
