Correct Answer: D

Rationale: Diaper dermatitis can be caused by various factors, one of which includes introducing new foods to the infant's diet. Discontinuing the new food that was added just before the rash can help identify and eliminate the potential cause. Options A and C are not directly related to addressing the cause of diaper dermatitis. While using cloth diapers rinsed in bleach may be a preventive measure for diaper dermatitis, it is not addressing a specific cause. Option B, advising against using occlusive ointments on the rash, may actually be beneficial in managing diaper dermatitis, but it does not address the cause of the condition.

Correct Answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

Correct Answer: B

Rationale: Assertive communication respects the rights and responsibilities of both parties. Choice B is the best example of assertive communication in this scenario. It addresses the issue directly by requesting clarification without blaming or devaluing the prescriber. This approach shows concern for safe practice and acknowledges the importance of clear communication in healthcare. Choices A, C, and D either involve self-depreciation, blaming the prescriber, or making demands without a respectful request for clarification, making them less effective in promoting effective communication and safe patient care.

Correct Answer: C

Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.

Correct Answer: C

Rationale: The correct answer is self-blame. In this scenario, the victim is attributing the abuse to their own inadequacies or faults, thinking that if they were different, the abuse would not occur. This is a common response seen in victims of domestic violence, where they wrongly internalize the blame for the abuser's actions. Fear (Choice A) is a valid emotion, but in this case, the victim is not expressing fear but rather self-blame. Helplessness (Choice B) is also a common feeling in victims of domestic violence, but in this specific statement, the victim is demonstrating self-blame. Rejection (Choice D) does not accurately reflect the victim's statement and emotional response in the given scenario.
