Which finding would delay a computed tomography (CT) scan?
- A. Patient's allergy to shellfish or iodine
- B. Patient has a suspected tumor
- C. Patient's allergy to milk products
- D. Patient's gluten intolerance
Correct Answer: A
Rationale: Allergy to shellfish predicts an allergy to iodine, the contrast media used in the CT scan. This test can detect tumors of the soft tissue; it is not contraindicated when the patient has a suspected tumor. Allergy to milk or intolerance to gluten is not a reason to delay a CT scan.

Which patient statement indicates the need for additional teaching for a patient with rheumatoid arthritis who is taking meloxicam?
- A. I am keeping a daily record of my blood pressure.'
- B. I take aspirin before I go to bed.'
- C. I know I can take meloxicam with or without regard to meals.'
- D. I weigh every day so I will be aware of any weight gain.'
Correct Answer: B
Rationale: Aspirin or products containing aspirin should be avoided while taking meloxicam. While taking meloxicam, there is no reason to record blood pressure readings. This medication can be taken without regard to meals. Meloxicam does not cause weight gain.
The patient that has a bipolar hip replacement following an intracapsular fracture has an order to be turned every 2 hours. The nurse understands that the correct nursing intervention is to keep the legs in which position?
- A. together so they do not separate while turning.
- B. flexed to stabilize the prosthesis.
- C. abducted so the prosthesis does not become dislocated.
- D. adducted to prevent additional pain for the patient with turning.
Correct Answer: C
Rationale: Nursing interventions also involve postoperative maintenance of leg abduction by using an abduction splint for 7 to 10 days to prevent dislocation of the prosthesis. Leg abduction does not involve keeping the legs together, flexion to stabilize the prosthesis or to keep the legs adducted to prevent additional pain with turning.
A patient has been casted to stabilize a fracture of the right radius and ulna. The nurse assesses a capillary refill of 5 seconds and cold fingers of the right hand. Which initial intervention should the nurse deploy?
- A. Notify the charge nurse of a probable compartment syndrome.
- B. Apply a warm compress to the fingers to relieve swelling.
- C. Elevate the right hand to heart level to maintain arterial pressure.
- D. Cut the cast off to release constriction.
Correct Answer: C
Rationale: The nurse should first elevate the right hand to heart level and notify the charge nurse. Permanent damage can occur in as little time as 6 hours. While the charge nurse does need to be notified it is most crucial to elevate the hand to heart level first. A warm compress would likely cause blood vessels to dilate, worsening the edema. The nurse cannot independently cut the cast off.
When the patient with rheumatoid arthritis reports not liking daily exercise, the nurse encouragingly reminds the patient that exercise has which benefit?
- A. Keeping the joints from 'freezing.'
- B. Ensuring longer and better sleep.
- C. Stimulating joints when done vigorously
- D. When performed weekly, having greater benefits.
Correct Answer: A
Rationale: Daily gentle exercises keep the joints from 'freezing' and keep the muscles from weakening. Exercise does not ensure better sleep. Joint exercises should not be performed vigorously. The patient benefits when gently exercises are performed daily.
The nurse explains to a patient who has had a hip replacement that warfarin is prescribed for which reason?
- A. increase the red blood cells.
- B. reduce the threat of hemorrhage.
- C. prevent formation of emboli.
- D. help stabilize the prosthesis.
Correct Answer: C
Rationale: Warfarin is a standard postsurgical drug to prevent the formation of emboli. Warfarin does not increase red blood cells. The risk of hemorrhage is higher when an anticoagulant is taken. Warfarin does not help stabilize the prosthesis.
