HESI Fundamentals Practice Exam
1. Which serum laboratory value should the nurse monitor carefully for a client who has had an NG tube for suctioning for the past week?
- A. White blood cell count
- B. Albumin
- C. Calcium
- D. Sodium
Correct answer: D
Rationale: The nurse should carefully monitor serum sodium levels for a client with an NG tube on suction for an extended period due to potential fluid loss and the risk of developing hyponatremia, an electrolyte imbalance. Hyponatremia can occur as a result of continual suctioning leading to fluid loss, making it crucial to monitor sodium levels to prevent complications associated with low sodium levels. Monitoring white blood cell count, albumin, or calcium is not directly related to the impact of NG tube suction on fluid and electrolyte balance, so these values are not the priority in this scenario.
2. The client is being taught how to self-administer a subcutaneous injection. To ensure sterility of the procedure, which subject is most important for the instructor to include in the teaching plan?
- A. Hand washing before preparing the injection.
- B. Technique for drawing medication from a vial.
- C. Selection and rotation of injection sites.
- D. Proper disposal of injection equipment.
Correct answer: B
Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial. This ensures that the medication remains sterile during preparation and administration. While hand washing, injection site selection, and equipment disposal are important aspects of injection safety, the key focus should be on maintaining the sterility of the medication itself to prevent infections and ensure the effectiveness of the treatment.
3. When assessing for orthostatic hypotension during blood pressure measurement, what action should the nurse implement first?
- A. Position the client supine for a few minutes
- B. Assist the client to stand at the bedside
- C. Apply the blood pressure cuff securely
- D. Record the client’s pulse rate and rhythm
Correct answer: A
Rationale: When assessing for orthostatic hypotension, the initial step is to position the client supine for a few minutes. This allows the body to adjust to the supine position before assessing blood pressure changes that may indicate orthostatic hypotension. By observing the blood pressure after the client has rested supine, the nurse can accurately assess for any drop in blood pressure upon standing, which is indicative of orthostatic hypotension. Choices B, C, and D are incorrect as they do not address the initial step in assessing for orthostatic hypotension, which is ensuring the client is positioned correctly to detect blood pressure changes upon standing.
4. During the digital removal of a fecal impaction, the nurse should stop the procedure and take corrective action if which client reaction is noted?
- A. Temperature increases from 98.8° to 99.0° F.
- B. Pulse rate decreases from 78 to 52 beats/min.
- C. Respiratory rate increases from 16 to 24 breaths/min.
- D. Blood pressure increases from 110/84 to 118/88 mmHg.
Correct answer: B
Rationale: During digital removal of a fecal impaction, a vagal response can occur due to stimulation of the anal sphincter. If the client experiences bradycardia (pulse rate decreases), the nurse should stop the procedure immediately and take corrective action to prevent any complications. Choices A, C, and D are incorrect because they do not indicate a vagal response, which is the expected adverse reaction during this procedure.
5. 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.
