Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Increasing physical activity helps in maintaining a healthy weight and overall health. 2. Regular exercise can reduce the risk of chronic diseases like heart disease and diabetes. 3. Physical activity improves mental health and overall well-being. 4. Exercise boosts immunity and helps in managing stress levels. Summary of why other choices are incorrect: B. Keeping total fat intake to 10% or less is a specific dietary recommendation and not a comprehensive approach to staying healthy. C. Maintaining body weight in a healthy range is important but does not encompass all aspects of staying healthy. D. Choosing and preparing foods with little salt is a specific dietary recommendation and does not address the importance of physical activity in staying healthy.

Correct Answer: C

Rationale: The correct answer is C because an older patient with glaucoma is at risk for increased intraocular pressure when receiving an enema. This situation requires immediate attention to prevent potential complications like vision loss. The other choices do not pose immediate risks that require urgent intervention. A and B can wait for a brief period, while D is not time-sensitive in the context of a myocardial infarction. The priority is always given to the patient with the highest risk of harm if the intervention is delayed.

Correct Answer: A

Rationale: Correct Answer: A. Maintain the irrigation fluid at a warm temperature. Rationale: 1. Warm fluid helps prevent vertigo and nausea by minimizing stimulation of the vestibular system. 2. Cold fluid can cause dizziness and nausea due to the temperature effect on the inner ear. 3. Warm fluid promotes patient comfort and relaxation during the procedure. 4. Cold fluid can lead to vasoconstriction, potentially exacerbating ear discomfort. Summary of other choices: B. Instilling short, sharp bursts of fluid can be uncomfortable and increase the risk of vertigo and nausea. C. Following with a curette may not be necessary if the irrigation effectively removes the impacted cerumen. D. Having the patient stand can increase the risk of falling or losing balance due to potential dizziness from the procedure.

Correct Answer: C

Rationale: The correct answer is C: Permanent vascular damage. Priapism is a prolonged erection that can lead to ischemia and damage to the penile tissue due to impaired blood flow, potentially resulting in permanent vascular damage. Urinary tract infection (A) is unrelated to priapism. Chronic pain (B) may occur but is not the primary concern. Future erectile dysfunction (D) can result from priapism but is not as immediate or severe as permanent vascular damage. Therefore, C is the most critical consequence to address in priapism.

Correct Answer: D

Rationale: The correct answer is D: Demographic changes in the population. This is because as the population ages, there is a higher prevalence of chronic illnesses and an increased number of people facing end-of-life care needs. This has led to a greater demand for palliative and hospice care services, shifting the focus of nursing towards providing care for the dying. A: Increased incidence of infections and acute illnesses is not the primary factor contributing to the increased focus on care for the dying. While these conditions do require nursing care, they do not directly explain the shift in focus. B: Increased focus of health care providers on disease prevention is important but does not directly explain the increased attention on care for the dying. Disease prevention aims to reduce the incidence of illnesses, not necessarily address end-of-life care needs. C: Larger numbers of people dying in hospital settings may be a consequence of the increased focus on care for the dying, but it is not the underlying phenomenon driving the shift in nursing care towards end-of
