Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. How should a healthcare professional prepare a patient for a colonoscopy?

• A. Provide clear instructions on diet
• B. Explain the procedure in detail
• C. Ensure the patient has an empty stomach
• D. Give a bowel prep solution

Correct answer: D

Rationale: Giving a bowel prep solution is essential to clean out the colon thoroughly before a colonoscopy. This process is crucial as it helps to achieve a clear view of the colon during the procedure. Providing clear instructions on diet (Choice A) and ensuring the patient has an empty stomach (Choice C) are important steps in the preparation process but may not be sufficient on their own to adequately cleanse the colon. Explaining the procedure in detail (Choice B) is helpful for patient education but does not directly contribute to the physical preparation required for a successful colonoscopy.

3. A nurse is assessing a client who has a sodium level of 125 mEq/L. Which of the following findings should the nurse expect?

• A. Increased appetite
• B. Dry mucous membranes
• C. Hypotension
• D. Hyperreflexia

Correct answer: C

Rationale: A sodium level of 125 mEq/L indicates hyponatremia, which can lead to hypotension. Hyponatremia is associated with signs such as confusion and weakness, rather than increased appetite, dry mucous membranes, or hyperreflexia. Therefore, the nurse should expect hypotension as a finding in a client with a sodium level of 125 mEq/L.

4. A client with heart failure is receiving furosemide. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 80/min.
• B. Weight loss of 1.1 kg (2.5 lb) in 24 hours.
• C. Potassium level of 3.8 mEq/L.
• D. Urine output of 60 mL/hr.

Correct answer: B

Rationale: A weight loss of 1.1 kg (2.5 lb) in 24 hours may indicate dehydration or fluid imbalance, which should be reported. This rapid weight loss could be a sign of excessive diuresis, potentially leading to hypovolemia or electrolyte imbalances. Monitoring weight changes is crucial in clients with heart failure receiving diuretics. The other findings are within normal ranges and expected in a client receiving furosemide for heart failure. A heart rate of 80/min, a potassium level of 3.8 mEq/L, and a urine output of 60 mL/hr are generally acceptable in this scenario.

5. A nurse is caring for a client who has a new prescription for levothyroxine. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Calcium
• B. Sodium
• C. Thyroid-stimulating hormone (TSH)
• D. Magnesium

Correct answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.
