A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?
- A. White blood cell count of 6,000/mm³
- B. Urine specific gravity of 1.025
- C. History of asthma
- D. History of allergy to shellfish
Correct Answer: D
Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

A client has a chest tube connected to a water-seal drainage system. Which of the following actions should be taken?
- A. Clamp the chest tube during ambulation
- B. Keep the collection chamber below the level of the chest
- C. Add sterile water to the water-seal chamber
- D. Empty the collection chamber every 12 hours
Correct Answer: C
Rationale: The correct action for the nurse to take when caring for a client with a chest tube connected to a water-seal drainage system is to add sterile water to the water-seal chamber. This is necessary to maintain the correct water level for proper chest tube function. Clamping the chest tube during ambulation (Choice A) is incorrect as it can lead to complications by obstructing drainage. Keeping the collection chamber below the level of the chest (Choice B) is incorrect because it should be kept below the chest to facilitate drainage. Emptying the collection chamber every 12 hours (Choice D) is incorrect as it should be emptied whenever it reaches the fill line or as per facility policy, not on a fixed time schedule.
A client in active labor has ruptured membranes. What action should the nurse take?
- A. Apply a fetal heart rate monitor.
- B. Initiate fundal massage.
- C. Administer oxytocin IV.
- D. Insert an indwelling urinary catheter.
Correct Answer: A
Rationale: When a client in active labor has ruptured membranes, the priority action for the nurse is to apply a fetal heart rate monitor. This is crucial for continuous monitoring of the baby's heart rate and ensuring fetal well-being. Initiating fundal massage may be indicated for uterine atony after delivery, not for ruptured membranes during labor. Administering oxytocin IV could be appropriate in some cases to augment labor, but it is not the immediate priority after ruptured membranes. Inserting an indwelling urinary catheter is not necessary solely based on ruptured membranes; it may be indicated for specific situations like epidural anesthesia where the client cannot void.
A client is 2 hr postoperative following a total hip arthroplasty. Which of the following actions should the nurse take?
- A. Position the client supine with a pillow between the legs.
- B. Place an abduction pillow between the client's legs.
- C. Place a pillow under the client's knees.
- D. Position the client's legs in adduction.
Correct Answer: B
Rationale: After a total hip arthroplasty, it is crucial to prevent hip dislocation. Placing an abduction pillow between the client's legs helps maintain proper alignment of the hip joint and prevents adduction, which could lead to dislocation. Therefore, choice B is the correct action. Choice A is incorrect because positioning the client supine with a pillow between the legs does not provide the necessary abduction to prevent dislocation. Choice C, placing a pillow under the client's knees, does not address the need for abduction. Choice D, positioning the client's legs in adduction, is incorrect as adduction increases the risk of hip dislocation following hip arthroplasty.
A client is receiving furosemide for heart failure. Which of the following findings should the nurse report to the provider?
- A. Weight loss of 0.5 kg (1.1 lb) in 24 hours.
- B. Heart rate of 68/min.
- C. Potassium level of 3.8 mEq/L.
- D. Urine output of 60 mL/hr.
Correct Answer: B
Rationale: The correct answer is B. A heart rate of 68/min is lower than expected and should be reported as it may indicate digoxin toxicity. Choices A, C, and D are within normal limits for a client receiving furosemide for heart failure and do not require immediate reporting. Weight loss may be expected due to diuretic therapy, a potassium level of 3.8 mEq/L is within the normal range, and a urine output of 60 mL/hr indicates adequate renal perfusion.
A nurse is assessing a client who has Guillain-Barr© syndrome. Which of the following findings should the nurse expect?
- A. Increased urine output.
- B. Hyperactive reflexes.
- C. Hypoactive bowel sounds.
- D. Facial weakness.
Correct Answer: D
Rationale: Facial weakness is a common finding in clients with Guillain-Barr© syndrome due to muscle weakness. While increased urine output is not typically associated with Guillain-Barr© syndrome, hyperactive reflexes are more indicative of conditions like hyperthyroidism or spinal cord injury. Hypoactive bowel sounds are not a classic finding in Guillain-Barr© syndrome, making it an incorrect choice.
