Nursing Elites

1. A client with pneumonia has a decrease in oxygen saturation from 94% to 88% while ambulating. Based on these findings, which intervention should the LPN/LVN implement first?

• A. Assist the ambulating client back to the bed.
• B. Encourage the client to ambulate to resolve pneumonia.
• C. Obtain a prescription for portable oxygen while ambulating.
• D. Move the oximetry probe from the finger to the earlobe.

Correct answer: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

2. A client with a new diagnosis of diabetes mellitus is being taught how to administer insulin. Which of the following instructions should the nurse include?

• A. Administer the insulin in the same body area each time.
• B. Store the insulin according to the manufacturer's instructions.
• C. Rotate injection sites within the same body area.
• D. Inject the insulin at a 45-degree angle.

Correct answer: C

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same body area. This practice helps prevent lipodystrophy, a condition characterized by the thickening or thinning of subcutaneous fat at the injection sites, which can affect insulin absorption. Choice A is incorrect because administering insulin in the same area each time can lead to lipodystrophy. Choice B is incorrect as insulin should be stored according to the manufacturer's instructions, which may include refrigeration. Choice D is incorrect because the angle of insulin injection (usually 90 degrees) is determined by the length of the needle and the amount of subcutaneous fat, not a fixed 45-degree angle.

3. A nurse is called away for an emergency while conversing with a client who is concerned about his medical diagnosis. The nurse returns to the client promptly, as promised. Which of the following ethical principles is the nurse demonstrating?

• A. Fidelity
• B. Autonomy
• C. Beneficence
• D. Justice

Correct answer: A

Rationale: The correct answer is A: Fidelity. Fidelity in nursing ethics involves keeping promises and being faithful to commitments, demonstrating reliability and trustworthiness. In this scenario, the nurse is exemplifying fidelity by returning promptly to the client as promised. Choice B, Autonomy, refers to respecting a patient's right to make their own decisions, not relevant in this situation. Choice C, Beneficence, involves the duty to act in the best interest of the patient, which is not the primary focus here. Choice D, Justice, pertains to fairness and equity in the distribution of healthcare resources, not applicable to the nurse's actions in this case.

4. While reviewing the medical records of a client with a pressure ulcer, a nurse should expect which of the following findings?

• A. Albumin level of 3 g/dL
• B. Hemoglobin level of 12 g/dL
• C. WBC count of 6,000/mm³
• D. Blood glucose level of 100 mg/dL

Correct answer: A

Rationale: An albumin level below 3.5 g/dL indicates protein deficiency, which can impair wound healing and contribute to pressure ulcer formation. Hemoglobin level and WBC count are not directly associated with pressure ulcers. Blood glucose level, while important for overall health, is not specifically linked to pressure ulcer development.

5. 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.
