Correct Answer: B

Rationale: The correct answer is B: Hematoma at the surgical site. This is a potential complication of cervical discectomy due to the risk of bleeding post-surgery. Hematoma can compress nearby structures and lead to increased pain and swelling. A: Vertebral fracture is not a typical complication of cervical discectomy, as the surgery aims to relieve pressure on the spinal cord caused by a herniated disc, not to cause fractures. C: Scoliosis is a condition characterized by abnormal lateral curvature of the spine, and it is not directly related to cervical discectomy. D: Renal trauma is not a common complication of cervical discectomy, as the surgery focuses on the cervical spine and does not involve the kidneys or renal system.

Correct Answer: D

Rationale: The correct answer is D because it emphasizes the importance of consistent and correct condom use in preventing HIV transmission. Here's the rationale: 1. Abstinence is the most effective way to prevent HIV, but since the teen is sexually active, abstinence may not be feasible for her. 2. Using condoms consistently and correctly is the next best method for preventing HIV transmission during sexual activity. 3. Choice A is incorrect because it implies that using condoms is not effective, which is not true. 4. Choice B is incorrect because it only mentions female condoms, while both male and female condoms can be effective in preventing HIV. 5. Choice C is incorrect because while new prevention methods are being researched, the established method of consistent condom use remains the most effective.

Correct Answer: C

Rationale: The correct answer is C: Semisolid food with thick liquids. Patients with Parkinson's disease often have dysphagia, leading to aspiration and respiratory complications. Semisolid food with thick liquids helps prevent aspiration and promotes safer swallowing. TPN (A) is not necessary for meeting nutritional needs unless the patient cannot tolerate oral intake. A low-residue diet (B) may not address the specific swallowing issues in Parkinson's disease. Minced foods and fluid restriction (D) may not provide adequate nutrition and hydration.

Correct Answer: C

Rationale: The correct choice is C because if no urine is obtained, it indicates that the catheter is not in the urethra. The nurse should remove the catheter, wipe with alcohol to maintain cleanliness, and reinsert after lubrication to ensure proper placement in the urethra. This step-by-step approach allows for a more accurate catheter insertion and prevents potential complications. Choice A is incorrect as discarding the catheter and starting over without addressing the issue does not solve the problem. Choice B is incorrect as filling the balloon with sterile water is not relevant to the situation of catheter misplacement. Choice D is incorrect as leaving the catheter in the vagina can lead to infection and is not a recommended practice.

Correct Answer: B

Rationale: The correct answer is B because injecting air into the stomach via the tube and auscultating helps confirm the tube placement in the stomach before administering the feeding. This step ensures the safety of the patient by preventing accidental lung feeding. Choice A is incorrect because securing the tube with a safety pin to the gown is not a standard practice and can lead to complications. Choice C is incorrect because the temperature of the feeding does not affect the tube placement or safety. Choice D is incorrect because checking the pH level is not a reliable method for verifying tube placement.
