1. A nurse administers insulin for a misread glucose level. What should the nurse monitor for?

Correct answer: A

Rationale: When a nurse administers insulin for a misread glucose level, they should monitor for hypoglycemia. Insulin lowers blood sugar levels, so the patient may experience hypoglycemia if given insulin unnecessarily. Monitoring for hypoglycemia involves observing for symptoms such as shakiness, sweating, dizziness, confusion, and palpitations. Choices B and C are incorrect because administering insulin for a misread glucose level would lower blood sugar levels, resulting in hypoglycemia, not hyperglycemia or hyperkalemia. Choice D is not the immediate priority; the focus should be on patient safety and monitoring for potential adverse effects of the unnecessary insulin.

2. What ECG changes are expected in a patient with hypokalemia?

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

3. What are the expected manifestations in a patient experiencing a thrombotic stroke?

Correct answer: A

Rationale: The correct manifestation in a patient experiencing a thrombotic stroke is sudden numbness or loss of function on one side of the body. This is due to the blockage of a blood vessel by a clot, leading to a lack of blood flow to a specific part of the brain. Choices B, C, and D are incorrect. Sudden loss of consciousness and seizure are more commonly associated with hemorrhagic strokes. Gradual onset of difficulty speaking is often seen in ischemic strokes affecting language areas, not specifically in thrombotic strokes. Loss of sensation in the affected limb is more indicative of sensory nerve damage rather than the motor deficits seen in thrombotic strokes.

4. What is the initial action for treating chest pain in acute coronary syndrome?

Correct answer: A

Rationale: The correct initial action for treating chest pain in acute coronary syndrome is to administer sublingual nitroglycerin. Nitroglycerin helps dilate blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle. Administering aspirin can also be beneficial, but the priority is to address chest pain promptly. Checking cardiac enzymes and obtaining IV access are important steps but are not the initial actions needed to alleviate chest pain in acute coronary syndrome.

5. A nurse is caring for a client who has a new diagnosis of tuberculosis. Which of the following precautions should the nurse initiate to prevent transmission of the disease?

Correct answer: B

Rationale: Tuberculosis is spread through small droplets measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client who has TB under airborne precautions to prevent the spread of microbes. Choice A, contact precautions, are used for diseases spread by direct or indirect contact. Choice C, droplet precautions, are for diseases spread by larger droplets. Choice D, protective environment, is used for immunocompromised clients to protect them from environmental pathogens.
