Correct Answer: A

Rationale: The correct answer is A: Pelvic floor exercises. Pelvic floor exercises help strengthen the muscles that control urination, promoting continence. These exercises can improve bladder control and reduce urinary incontinence post-prostatectomy. Intermittent urinary catheterization (B) may lead to increased risk of infection. Reduced physical activity (C) can weaken pelvic floor muscles, worsening incontinence. Active range of motion exercises (D) do not directly address urinary incontinence.

Correct Answer: A

Rationale: The correct answer is A because an ultrasound-guided core biopsy is indeed faster, less expensive, and does not use radiation. - "Faster": Ultrasound-guided biopsies are typically quicker compared to stereotactic biopsies, as they are performed in real-time using ultrasound imaging. - "Less expensive": Ultrasound-guided biopsies are generally more cost-effective than stereotactic biopsies due to the equipment and resources required. - "Does not use radiation": Unlike stereotactic biopsies which involve the use of X-rays for guidance, ultrasound-guided biopsies do not expose the patient to radiation, making them safer in that aspect. The other choices are incorrect because they either inaccurately state that ultrasound-guided biopsies use radiation (C), take more time (D), or imply a slight increase in cost without highlighting the key advantages of speed and lack of radiation (B).

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.

Correct Answer: D

Rationale: The correct answer is D because it addresses a crucial aspect of preoperative care for a patient undergoing a hysterectomy due to endometriosis. Emptying the bladder before surgery helps prevent urinary retention postoperatively. Placing a catheter during surgery ensures proper drainage and prevents bladder distention. This education topic is essential for the patient's comfort and well-being during and after the procedure. Choices A, B, and C are incorrect: A: Menstrual periods will not continue after a hysterectomy as the uterus is removed. B: Normal activity is usually restricted after a hysterectomy to promote healing. C: Hormone levels are affected after a hysterectomy, especially if the ovaries are also removed.

Correct Answer: B

Rationale: Step 1: Prostate surgery can damage nerves responsible for erectile function. Step 2: Nerve damage can lead to erectile dysfunction post-prostatectomy. Step 3: Choice B correctly states that all prostatectomies carry a risk of nerve damage and consequent erectile dysfunction, aligning with the potential impact of surgery on sexual function. Step 4: Other choices lack accuracy: A incorrectly attributes erectile dysfunction solely to hormonal changes, C falsely suggests temporary nature of dysfunction, and D wrongly claims no risk of dysfunction due to modern techniques.
