Nursing Elites

1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

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 client has extracellular fluid volume deficit. Which of the following findings should the nurse expect?

• A. Postural hypotension
• B. Distended neck veins
• C. Dependent edema
• D. Bradycardia

Correct answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

4. A nurse is preparing to administer enoxaparin subcutaneously. Which of the following actions should the nurse take?

• A. Administer the medication with the needle at a 45-degree angle.
• B. Administer the medication with the needle at a 90-degree angle.
• C. Administer the medication with the needle at a 30-degree angle.
• D. Administer the medication with the needle at a 15-degree angle.

Correct answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

5. When assessing the respiratory system for complications of immobility, what action should the nurse take?

• A. Inspect chest wall movements primarily during the expiratory cycle.
• B. Auscultate the entire lung region to assess lung sounds.
• C. Focus auscultation on the upper lung fields.
• D. Assess the patient at least every 4 hours.

Correct answer: B

Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.
