Correct Answer: B

Rationale: The correct answer is B: In a flat side-lying position. Rationale: 1. A flat side-lying position helps reduce pressure on the surgical site, promoting comfort and preventing injury. 2. This position minimizes strain on the spine and supports proper alignment. 3. High Fowlers position may increase pressure on the surgical area due to increased intra-abdominal pressure. 4. Trendelenberg position and reverse Trendelenberg position are not appropriate for spine surgery patients as they can cause increased blood flow to the surgical site, leading to potential complications.

Correct Answer: D

Rationale: The correct answer is D: Surgical intervention. Cataracts are a clouding of the lens in the eye, which can lead to vision impairment. Surgery is the most common and effective treatment for cataracts, involving the removal of the cloudy lens and replacement with an artificial one. Antioxidant supplements (Choice A) may help prevent cataracts but are not a treatment for existing ones. Eyeglasses or magnifying lenses (Choice B) can help with vision correction but do not address the cataracts themselves. Corticosteroid eye drops (Choice C) are used for treating inflammation in the eye, not cataracts. Therefore, surgical intervention is the most appropriate treatment option for age-related cataracts.

Correct Answer: B

Rationale: The correct answer is B: Administer calcium gluconate. Magnesium sulfate can cause respiratory depression, leading to a low respiratory rate. Calcium gluconate is the antidote for magnesium sulfate toxicity, as it antagonizes the effects of magnesium on the neuromuscular junction. Administering calcium gluconate helps reverse the respiratory depression caused by magnesium sulfate. Increasing IV fluids (Choice A) is not directly related to treating respiratory depression. Vigorously stimulating the patient (Choice C) can exacerbate respiratory depression. Instructing the patient to take deep breaths (Choice D) may not be effective in addressing the underlying cause of respiratory depression due to magnesium sulfate toxicity.

Correct Answer: A

Rationale: The correct answer is A because habit training involves keeping a bladder diary to identify patterns and develop a toileting schedule. This helps in promoting regular voiding habits. B is incorrect because timed voiding isn't solely based on the patient's urge to void, but rather on a predetermined schedule. C is incorrect as prompted voiding involves reminding patients to use the restroom at regular intervals, not just asking if they are wet or dry. D is incorrect because elevating feet in patients with edema may help reduce swelling but has no direct impact on nighttime voiding.

Correct Answer: C

Rationale: The correct answer is C: Risk for falls. Patients with vertigo experience a false sensation of spinning or movement, which can lead to imbalance and increased risk of falls. Prioritizing the risk for falls is crucial to prevent injuries and ensure patient safety. Other choices are incorrect as they do not directly address the immediate safety concern of falls associated with vertigo. A: Risk for disturbed sensory perception may be present, but the priority is preventing falls. B: Risk for unilateral neglect is not typically associated with vertigo. D: Risk for ineffective health maintenance is important but falls take precedence due to the immediate risk of injury.
