Correct Answer: A

Rationale: Step 1: Mammograms use low-dose X-rays to create images of the breast tissue. Step 2: The radiation exposure in a mammogram is minimal and considered safe. Step 3: Choice A is correct as it states that mammograms do not use radiation, which is accurate. Step 4: Other choices are incorrect because B wrongly implies that annual mammograms are safe due to low radiation levels, C is incorrect as radiation effects can accumulate over time, and D is incorrect as the amount of radiation in a mammogram is much lower than an hour of sunlight.

Correct Answer: A

Rationale: The correct answer is A. Postoperative day 6 following tympanoplasty and mastoidectomy is still within the early phase of recovery, where occasional sharp, shooting pains in the affected ear can be expected due to the healing process. Here's a step-by-step rationale: 1. Timing: It is only day 6 post-surgery, so it is normal to experience some pain as part of the healing process. 2. Nature of pain: Sharp, shooting pains are common post-surgery due to tissue healing and nerve regeneration. 3. Lack of other symptoms: The patient did not report any other concerning symptoms like fever or discharge, which would be more indicative of an infection. 4. Unlikely complications: Spontaneous rupture of the tympanic membrane or unsuccessful surgery would typically present with more severe and consistent symptoms. Summary: - B: Unlikely as there are no other signs of infection. - C: Unlikely as the pain is described as occasional and sharp. - D:

Correct Answer: C

Rationale: The correct answer is C: Promote positive nitrogen balance. In a postsurgical patient, promoting positive nitrogen balance is crucial for wound healing and tissue repair. This goal helps prevent muscle wasting and promotes overall recovery. A: Reduce dependent nitrogen balance is incorrect as it does not address the need for positive nitrogen balance in wound healing. B: Maintain negative nitrogen balance is incorrect because negative nitrogen balance indicates a loss of protein stores, which is detrimental for healing. D: Facilitate neutral nitrogen balance is incorrect as it does not actively support the increased protein needs for wound repair.

Correct Answer: C

Rationale: The correct answer is C: anticonvulsant. Magnesium sulfate is used in the treatment of preeclampsia to prevent seizures, making it an anticonvulsant. It works by reducing neuromuscular excitability and stabilizing nerve cell membranes. Choice A (diuretic) is incorrect because magnesium sulfate does not primarily promote diuresis. Choice B (tocolytic) is incorrect as it does not inhibit uterine contractions. Choice D (antihypertensive) is incorrect because although magnesium sulfate can help lower blood pressure in preeclampsia, its primary indication in this case is for seizure prophylaxis.

Correct Answer: A

Rationale: The correct answer is A: Testicular cancer is a highly curable type of cancer. This is the most appropriate point to emphasize because early detection through regular self-examinations can lead to early treatment and a high survival rate. Testicular cancer has a very high cure rate, especially when detected and treated early. Emphasizing this point encourages boys to perform monthly self-exams, leading to early detection and better outcomes. Explanation of other choices: B: Testicular cancer is very difficult to diagnose - This is incorrect because testicular cancer is actually one of the more easily detectable cancers through self-examinations. C: Testicular cancer is the number one cause of cancer deaths in males - This is incorrect as testicular cancer is not the leading cause of cancer deaths in males. D: Testicular cancer is more common in older men - This is incorrect as testicular cancer is more common in younger men, typically between the ages of 15 and 44.
