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. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?

• A. 1/2 tablet.
• B. 1 tablet.
• C. 1 1/2 tablets.
• D. 2 tablets.

Correct answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

3. An elderly male client who suffered a cerebral vascular accident is receiving tube feedings via a gastrostomy tube. The LPN knows that the best position for this client during administration of the feedings is

• A. prone.
• B. Fowler's.
• C. Sims'.
• D. supine.

Correct answer: B

Rationale: Fowler's position is the optimal position for a client receiving tube feedings via a gastrostomy tube because it reduces the risk of aspiration. In Fowler's position, the client is sitting up at a 45- to 60-degree angle, which helps prevent the formula from flowing back into the esophagus and causing aspiration pneumonia. Choice A, prone position (lying face down), would not be suitable for administering tube feedings as it increases the risk of aspiration. Sims' position (lying on the left side with the right knee flexed) and supine position (lying flat on the back) are also not ideal for administering tube feedings as they do not provide the same level of protection against aspiration as Fowler's position does.

4. A nurse has an order to remove sutures from a client. After retrieving the suture removal kit and applying sterile gloves, which of the following actions should the nurse take next?

• A. Clean sutures along the incision site.
• B. Remove sutures using sterile technique.
• C. Inspect the wound for signs of infection.
• D. Document the removal of sutures.

Correct answer: B

Rationale: After applying sterile gloves, the nurse should proceed to remove the sutures using sterile technique. This step ensures the safe and effective removal of sutures without introducing infection. Choice A, cleaning sutures along the incision site, would not be the next step as the primary focus is on suture removal. Inspecting the wound for signs of infection (Choice C) is important but typically follows suture removal. Documenting the removal of sutures (Choice D) is essential but usually occurs after the procedure is completed.

5. A patient has been diagnosed with osteoporosis and lactose intolerance. What intervention will the nurse implement?

• A. Encourage dairy alternatives.
• B. Monitor intake of vitamin D.
• C. Increase intake of caffeinated drinks.
• D. Assist the patient with daily activities.

Correct answer: B

Rationale: The correct intervention for a patient diagnosed with osteoporosis and lactose intolerance is to monitor their intake of vitamin D. Since the patient has lactose intolerance, encouraging dairy alternatives (Choice A) would not be appropriate. Increasing intake of caffeinated drinks (Choice C) is not beneficial for managing osteoporosis and may even have negative effects on bone health. Assisting the patient with daily activities (Choice D) is a general nursing intervention that may not directly address the specific needs related to osteoporosis and lactose intolerance.
