Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A nurse is assessing the heart sounds of a client who has developed chest pain that becomes worse with inspiration. The nurse auscultates a high-pitched scratching sound during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border. Which of the following heart sounds should the nurse document?

• A. Pericardial friction rub
• B. Mitral stenosis
• C. Aortic regurgitation
• D. Tricuspid stenosis

Correct answer: B

Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.

3. The client is receiving discharge instructions for a new antihypertensive medication. Which statement by the client indicates a need for further teaching?

• A. I will stop taking the medication if I experience dizziness.
• B. I will monitor my blood pressure regularly.
• C. I will avoid drinking alcohol while taking this medication.
• D. I will rise slowly from a sitting to a standing position.

Correct answer: A

Rationale: The correct answer is A. Stopping antihypertensive medication abruptly can lead to rebound hypertension, which can be dangerous. Clients should never discontinue their medication without consulting their healthcare provider first. Choice B is correct because monitoring blood pressure is essential when taking antihypertensive medication to ensure it stays within the target range. Choice C is correct as alcohol can potentiate the hypotensive effects of antihypertensive medications. Choice D is correct as orthostatic hypotension can occur, so rising slowly helps prevent dizziness and falls. Therefore, choice A is the statement that indicates a need for further teaching.

4. A client requires bed rest and has a prescription for anti-embolic stockings. Which of the following actions should the nurse take?

• A. Apply the stockings with the creases on the front of the leg.
• B. Apply the stockings while the client's legs are in a dependent position.
• C. Remove the stockings at least once per shift.
• D. Remove the stockings while the client is sitting in a reclining chair.

Correct answer: C

Rationale: The correct action for the nurse to take is to remove the anti-embolic stockings at least once per shift. This is essential to assess the client's circulation and skin integrity. Option A is incorrect because the stockings should be applied without creases to ensure proper compression. Option B is incorrect as the stockings should be applied when the client's legs are elevated, not in a dependent position. Option D is incorrect as removing the stockings while the client is sitting in a reclining chair is not necessary and does not provide the appropriate assessment opportunity.

5. A nurse is reviewing evidence-based practice principles about the administration of oxygen therapy with a newly licensed nurse. Which of the following actions should the nurse include?

• A. Regulate oxygen via nasal cannula at a flow rate no more than 6 L/min
• B. Administer oxygen at a higher flow rate for better saturation
• C. Use a high-flow nasal cannula for all clients
• D. Adjust oxygen flow based on client comfort

Correct answer: A

Rationale: The correct answer is A. Regulating oxygen flow at no more than 6 L/min via nasal cannula is a safe practice to prevent potential complications such as oxygen toxicity. Option B suggesting administering oxygen at a higher flow rate for better saturation is incorrect as it can lead to adverse effects. Option C is incorrect because using a high-flow nasal cannula for all clients is not necessary and should be based on individual client needs. Option D is incorrect as adjusting oxygen flow solely based on client comfort without considering the prescribed flow rate can compromise the effectiveness of oxygen therapy.
