Correct Answer: A

Rationale: The correct answer is A: Falls. A cerebellar tumor can affect coordination and balance, leading to an increased risk of falls. Measures to prevent falls include maintaining a clutter-free environment, using assistive devices, and providing supervision. Choice B (Audio hallucinations) is incorrect as cerebellar tumors typically do not cause auditory hallucinations. Choice C (Respiratory depression) is incorrect as cerebellar tumors do not directly affect the respiratory system. Choice D (Labile BP) is incorrect as cerebellar tumors are not typically associated with blood pressure fluctuations.

Correct Answer: B

Rationale: The correct answer is B: Mammography. Mammography is the gold standard for diagnosing breast cancer as it can detect abnormalities such as lumps or tumors in the breast tissue. It provides detailed images that can help healthcare providers identify suspicious areas that may require further testing or biopsy. Supervised breast self-examination (choice A) is important for early detection but is not a diagnostic tool. Fine-needle aspiration (choice C) is a procedure used to obtain a sample of cells for further analysis but is not definitive for diagnosing breast cancer. Chest x-ray (choice D) is used to evaluate the lungs and heart, not the breast tissue for cancer.

Correct Answer: A

Rationale: The correct answer is A. Recording times when the patient is incontinent is crucial in identifying patterns and establishing a structured bowel training program. This data helps in determining the optimal timing for toileting. Choices B, C, and D are incorrect. Choice B is not specific to bowel training and may not address the patient's individual needs. Choice C is not a recommended posture for effective bowel elimination. Choice D, while important for overall health, is not directly related to bowel training.

Correct Answer: A

Rationale: The correct answer is A: Previous birth of large infant. This factor increases the risk of gestational diabetes mellitus due to a history of delivering a large baby, indicating a higher likelihood of insulin resistance in subsequent pregnancies. Maternal age younger than 25 years (B) is not a known risk factor for gestational diabetes. Being underweight prior to pregnancy (C) is actually associated with a decreased risk of gestational diabetes. A previous diagnosis of type 2 diabetes mellitus (D) is a separate condition and does not directly increase the risk of gestational diabetes.

Correct Answer: B

Rationale: The correct answer is B. Stress, like having three final examinations on the same day, can lead to increased peristalsis due to the activation of the sympathetic nervous system. This can result in faster movement of food through the digestive system. The other choices are incorrect because: A - Ignoring the urge to defecate does not directly relate to increased peristalsis. C - Major depressive disorder is more likely to be associated with decreased peristalsis due to the effects of stress on the body. D - Elderly individuals tend to have reduced peristalsis due to age-related changes in the digestive system.
