1. A client is admitted with a fever of unknown origin. To assess fever patterns, which intervention should the nurse implement?
- A. Document the client’s temperature fluctuations
- B. Assess for flushed, warm skin consistently
- C. Measure temperature at regular intervals
- D. Use different sites for temperature measurement
Correct answer: C
Rationale: To assess fever patterns accurately, the nurse should measure the client’s temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.
2. 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.
3. When performing sterile wound care in the acute care setting, the nurse obtains a bottle of normal saline from the bedside table that is labeled 'opened' and dated 48 hours prior to the current date. Which is the best action for the nurse to take?
- A. Use the normal saline solution once more and then discard.
- B. Obtain a new sterile syringe to draw up the labeled saline solution.
- C. Use the saline solution and then relabel the bottle with the current date.
- D. Discard the saline solution and obtain a new unopened bottle.
Correct answer: D
Rationale: When performing sterile wound care, it is essential to use only newly opened and unexpired solutions to maintain sterility and prevent infections. The normal saline solution obtained by the nurse is labeled 'opened' and dated 48 hours prior to the current date, making it no longer considered sterile. The best action for the nurse to take in this situation is to discard the saline solution and obtain a new unopened bottle to ensure the safety and effectiveness of wound care. Choices A, B, and C are incorrect because reusing an already opened and outdated solution or attempting to relabel it with a current date can compromise patient safety and increase the risk of infection.
4. The client is being taught how to perform active range of motion (ROM) exercises. To exercise the hinge joints, which action should the client be instructed to perform?
- A. Tilt the pelvis forwards and backwards
- B. Bend the arm by flexing the ulnar to the humerus
- C. Turn the head to the right and left
- D. Extend the arm at the side and rotate it in circles
Correct answer: B
Rationale: Hinge joints, like the elbow, primarily allow movement in one direction, in this case, bending the arm. The correct action to exercise hinge joints is to bend the arm by flexing the ulnar to the humerus. This movement specifically targets the hinge joint and promotes its range of motion. Choices A, C, and D involve movements that do not specifically target hinge joints. Tilt the pelvis involves the ball-and-socket joints of the hip, turning the head involves the pivot joint of the neck, and extending the arm and rotating it in circles involve multiple joints including ball-and-socket and pivot joints.
5. 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.
