1. Your patient has a retractable gastric peptic ulcer and has had a gastric vagotomy. Which factor increases as a result of vagotomy?
- A. Peristalsis.
- B. Gastric acidity.
- C. Gastric motility.
- D. Gastric pH.
Correct answer: D
Rationale: After a gastric vagotomy, the gastric pH increases as a result of reduced acid secretion.
2. What procedure involves using a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent?
- A. Angioplasty
- B. Valve replacement
- C. Coronary artery bypass graft (CABG)
- D. Endarterectomy
Correct answer: A
Rationale: The correct answer is A, Angioplasty. Angioplasty is a procedure that uses a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent to maintain vessel patency. Choice B, Valve replacement, involves replacing damaged heart valves, not treating narrowed blood vessels. Choice C, Coronary artery bypass graft (CABG), is a procedure to bypass blocked coronary arteries, not directly open them using a balloon. Choice D, Endarterectomy, is a surgical procedure to remove plaque from the inner lining of an artery, not involving the use of a balloon and stent to open a vessel.
3. A nurse is caring for a client who is experiencing acute alcohol withdrawal. Which of the following actions should the nurse take?
- A. Administer haloperidol as prescribed.
- B. Keep the client in a supine position.
- C. Administer lorazepam as prescribed.
- D. Encourage the client to drink fluids with meals.
Correct answer: C
Rationale: The correct action the nurse should take when caring for a client experiencing acute alcohol withdrawal is to administer lorazepam as prescribed. Lorazepam is a benzodiazepine used to prevent seizures and manage agitation in clients undergoing alcohol withdrawal. Administering haloperidol (Choice A) is not recommended in alcohol withdrawal as it may lower the seizure threshold. Keeping the client in a supine position (Choice B) is not specifically indicated in managing alcohol withdrawal. Encouraging the client to drink fluids with meals (Choice D) is important for hydration but does not address the acute symptoms of alcohol withdrawal.
4. When a client experiences a major incident, what is the time frame for reporting the incident?
- A. 24 hours.
- B. 36 hours.
- C. 48 hours.
- D. 72 hours.
Correct answer: A
Rationale: The correct answer is A: '24 hours.' It is crucial to report a major incident within 24 hours of its occurrence to ensure timely and accurate documentation. Reporting incidents promptly allows for a swift response and investigation to prevent future occurrences. Choices B, C, and D are incorrect as they exceed the recommended time frame for reporting a major incident, which is 24 hours.
5. A nurse is assessing a client who is 2 hours postoperative following a gastrectomy. Which of the following findings should the nurse report to the provider?
- A. Heart rate of 94/min
- B. Oxygen saturation of 88%
- C. Respiratory rate of 18/min
- D. Temperature of 37.6°C (99.7°F)
Correct answer: B
Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a serious condition post-gastrectomy. Hypoxemia can lead to inadequate oxygen delivery to tissues, potentially causing complications like organ dysfunction or failure. This finding requires immediate attention to prevent further deterioration. The heart rate, respiratory rate, and temperature are within normal ranges for a client post-gastrectomy, so they do not require immediate reporting to the provider.
