Nursing Elites

1. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

2. The nurse is providing discharge teaching to a client with a new diagnosis of osteoporosis. Which instruction should the nurse include?

• A. Increase dietary intake of calcium-rich foods.
• B. Avoid activities that increase the risk of falls.
• C. Avoid prolonged exposure to sunlight.
• D. Increase intake of vitamin D supplements.

Correct answer: B

Rationale: Avoiding activities that increase the risk of falls (B) is the most crucial instruction for a client with osteoporosis to prevent fractures. Osteoporosis weakens bones, making them more susceptible to fractures from falls. While increasing calcium intake (A) is important for bone health, avoiding falls takes precedence to prevent immediate harm. Avoiding prolonged exposure to sunlight (C) is not directly related to osteoporosis management. Increasing vitamin D supplements (D) is beneficial for bone health, but fall prevention is more critical in this scenario.

3. When assessing a client with wrist restraints, the nurse observes that the fingers on the right hand are blue. What action should the nurse implement first?

• A. Loosen the right wrist restraint.
• B. Apply a pulse oximeter to the right hand.
• C. Compare hand color bilaterally.
• D. Palpate the right radial pulse.

Correct answer: A

Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.

4. The client has a chest tube. What is the most important action for the nurse to take?

• A. Ensure the chest tube remains unclamped at all times.
• B. Empty the chest tube every 2 hours.
• C. Keep the drainage system below the level of the chest.
• D. Assess for subcutaneous emphysema.

Correct answer: C

Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.

5. The healthcare professional observes a UAP taking a client's blood pressure in the lower extremity. Which observation of this procedure requires the healthcare professional's intervention?

• A. The cuff wraps around the girth of the leg.
• B. The UAP auscultates the popliteal pulse with the cuff on the lower leg.
• C. The client is placed in a prone position.
• D. The systolic reading is 20 mm Hg higher than the blood pressure in the client's arm.

Correct answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.
