- A. Altered balance.

The nurse is instructing the client about postsurgery activity following cataract surgery. What position should the nurse teach the client to use?
- A. Remain in a semi-Fowler's position.
- B. Position the feet higher than the body.
- C. Lie on the operative side.
- D. Place the head in a dependent position.
Correct Answer: A
Rationale: A semi-Fowler's position (head elevated 30-45 degrees) helps reduce intraocular pressure and swelling by promoting drainage and preventing fluid accumulation in the surgical eye.
The nurse has been assigned to provide care for four clients at the beginning of the day shift. In what order should the nurse assess these clients?
- A. A client awaiting surgery for a hiatal hernia repair at 11 a.m.
- B. A client with suspected gastric cancer who is on nothing-by-mouth (NPO) status for tests.
- C. A client with peptic ulcer disease experiencing a sudden onset of acute stomach pain.
- D. A client who is requesting pain medication 2 days after surgery to repair a fractured jaw.
Correct Answer: C
Rationale: The client with sudden onset of acute stomach pain (C) should be assessed first, as this could indicate a serious complication like ulcer perforation. The other clients' conditions are less urgent: the hiatal hernia client is stable, the NPO client is awaiting tests, and the jaw surgery client's pain is expected postoperatively.
The nurse is supervising a newly hired nurse administer prescribed medications via a double-lumen nasogastric tube (NGT) with an air vent. Which action by the newly hired nurse requires follow-up?

Which of the following explains the influence of aging on the development of peripheral vascular disease?
- A. Decreased resistance
- B. Increased resistance
- C. Decreased viscosity
- D. Increased viscosity
Correct Answer: B
Rationale: Aging increases vascular resistance due to arterial stiffening and reduced elasticity from collagen buildup and atherosclerosis. This elevates blood pressure and impairs peripheral blood flow, contributing to PVD. Resistance does not decrease, and viscosity changes are less significant in aging-related PVD.
