Nursing Elites

1. A nurse is assessing a client with chronic kidney disease. Which laboratory value would indicate the need for hemodialysis?

• A. Glomerular filtration rate (GFR) 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 GFR of 14 mL/min indicates significant kidney damage and a severe decrease in kidney function. This level of GFR typically indicates the need for hemodialysis to help the kidneys perform their function adequately. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and managing chronic kidney disease but do not specifically indicate the need for hemodialysis. Therefore, choices B, C, and D are incorrect.

2. Before an amniocentesis, what action by the client will need to be completed?

• A. Increase fluid intake
• B. Empty the bladder
• C. Avoid eating for 12 hours
• D. Take a sedative

Correct answer: B

Rationale: Before an amniocentesis, the client should empty their bladder. This is necessary to reduce the risk of bladder puncture during the procedure. A full bladder can be in the path of the needle, increasing the risk of injury. Increasing fluid intake (choice A) is not necessary before an amniocentesis. Avoiding eating for 12 hours (choice C) is not a standard preparation for an amniocentesis. Taking a sedative (choice D) is not routinely required for this procedure.

3. A nurse is providing teaching to a client who is scheduled for electromyography (EMG). Which of the following information should the nurse include in the teaching?

• A. “You will receive a fixed dose of radioisotope 2 hours before the procedure.”
• B. “Momentary flushing may occur at the beginning of the procedure.”
• C. “You should inform your provider if you are claustrophobic.”
• D. “You should expect insertion of small needle electrodes into the muscles.”

Correct answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to identify muscle weakness and evaluate local nerve responses. This information is crucial for the client to know beforehand. Choice A is incorrect because radioisotopes are not used in EMG procedures. Choice B is incorrect because flushing is not a common occurrence during EMG. Choice C is incorrect because claustrophobia is more relevant to MRI or CT scans, not EMG procedures.

4. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

5. A nurse is caring for a client who is postoperative following a thyroidectomy. The client reports tingling in the fingers and around the mouth. The nurse should anticipate which of the following interventions?

• A. Administer calcium gluconate
• B. Provide a high-protein diet
• C. Administer levothyroxine
• D. Apply a warm compress to the client's neck

Correct answer: A

Rationale: Tingling in the fingers and around the mouth is a sign of hypocalcemia, which can occur after thyroid surgery due to accidental damage to the parathyroid glands. Hypocalcemia is common after thyroidectomy due to potential parathyroid damage. Calcium gluconate is the appropriate intervention to treat hypocalcemia. Providing a high-protein diet or administering levothyroxine are not indicated for hypocalcemia. Applying a warm compress to the client's neck would not address the underlying issue of hypocalcemia.
