Skin closure with heterograft will be performed on a client with a burn injury. When the client asks the nurse where the heterograft comes from, the nurse should explain it is from which source?
- A. A cadaver
- B. Another animal species
- C. The burned client themselves
- D. A man-made synthetic source
Correct Answer: B
Rationale: Biologic dressings are usually heterograft or homograft material. Heterograft is skin from another species. The most commonly used type of heterograft is pig skin because of its availability and its relative compatibility with human skin. Homograft is skin from another human, which is usually obtained from a cadaver and is provided through a skin bank. Autograft is skin from the client. Synthetic dressings are also available for covering burn wounds.

A client is scheduled to have a percutaneous transluminal coronary angioplasty (PTCA). What information about the balloon-tipped catheter should nurse plan to include when providing client education concerning the procedure?
- A. A mesh-like device within the catheter will be inflated causing it to spring open.
- B. The catheter will be used to compress the plaque against the coronary blood vessel wall.
- C. The catheter will cut away the plaque from the coronary vessel wall using an embedded blade.
- D. The catheter will be positioned in a coronary artery to take pressure measurements in the vessel.
Correct Answer: B
Rationale: In PTCA, a balloon-tipped catheter is used to compress the plaque against the coronary blood vessel wall. Option 1 describes placement of a coronary stent, option 3 describes coronary atherectomy, and option 4 describes part of the process used in cardiac catheterization.
The nurse is caring for a client diagnosed with a herniated lumbar intervertebral disk who is experiencing low back pain. Which position should the nurse place the client in to minimize the pain?
- A. Supine with the knees slightly raised
- B. High Fowler's position with the foot of the bed flat
- C. Semi-Fowler's position with the foot of the bed flat
- D. Semi-Fowler's position with the knees slightly raised
Correct Answer: D
Rationale: Clients with low back pain are often more comfortable in the semi-Fowler's position with the knees raised sufficiently to flex the knees (William's position). This relaxes the muscles of the lower back and relieves pressure on the spinal nerve root. Keeping the bed flat or lying in a supine position with the knees raised would excessively stretch the lower back. Keeping the foot of the bed flat will enhance extension of the spine.
A client seeks medical attention for intermittent signs and symptoms that suggest a diagnosis of Raynaud's disease. The nurse should assess the trigger of these signs/symptoms by asking which question?
- A. Does being exposed to heat seem to cause the episodes?
- B. Do the signs and symptoms occur while you are asleep?
- C. Does drinking coffee or ingesting chocolate seem related to the episodes?
- D. Have you experienced any injuries that have limited your activity levels lately?
Correct Answer: C
Rationale: Raynaud's disease is vasospasm of the arterioles and arteries of the upper and lower extremities. It produces closure of the small arteries in the distal extremities in response to cold, vibration, or external stimuli. Episodes are characterized by pallor, cold, numbness, and possible cyanosis of the fingers, followed by erythema, tingling, and aching pain. Attacks are triggered by exposure to cold, nicotine, caffeine, trauma to the fingertips, and stress. Prolonged episodes of inactivity are unrelated to these episodes.
The nurse is caring for a client with a nasogastric tube that is attached to low suction. If the client's HCO3- is 30, which additional value is most likely to be noted in this client?
- A. pH 7.52
- B. pH 7.36
- C. pH 7.25
- D. pH 7.20
Correct Answer: A
Rationale: Loss of gastric fluid via nasogastric suction or vomiting causes metabolic alkalosis because of the loss of hydrochloric acid (HCl), an acid secreted in the stomach. This occurs as HCO3 rises above normal. Thus, the loss of hydrogen ions in the HCl results in alkalosis. A pH above 7.45 would be noted.
A client who has sustained a neck injury is unresponsive and pulseless. What should the emergency department nurse do to open the client's airway?
- A. Insert oropharyngeal airway.
- B. Tilt the head and lift the chin.
- C. Place in the recovery position.
- D. Stabilize the skull and push up the jaw.
Correct Answer: D
Rationale: The health care team uses the jaw-thrust maneuver to open the airway until a radiograph confirms that the client's cervical spine is stable to avoid potential aggravation of a cervical spine injury. Options 1 and 2 require manipulation of the spine to open the airway, and option 3 can be ineffective for opening the airway.
