Correct Answer: D

Rationale: The correct answer is D: Frequent douching. Douching disrupts the natural balance of vaginal flora, making the environment more susceptible to infections. High estrogen levels (A) can actually protect against vaginal infections. Late menarche (B) and nonpregnant state (C) are not direct risk factors for vaginal infections. In summary, frequent douching is the most significant risk factor as it disrupts the vaginal microbiome.

Correct Answer: C

Rationale: The nurse will use the history of angina for "B" when using SBAR because it provides relevant background information about the patient's cardiac condition. This helps the nurse understand the context of the current situation and make appropriate decisions. Pulse rate of 108 (choice B) is a specific vital sign and not an appropriate choice for "B" in SBAR. Having chest pain (choice A) is important but does not provide the necessary background information like the history of angina does. Oxygen being needed (choice D) is a current intervention and not relevant for "B" in SBAR, which focuses on providing background information.

Correct Answer: D

Rationale: The correct answer is D, balancing calories. This is because the ChooseMyPlate program emphasizes the importance of maintaining a balance between the calories consumed and calories expended for overall health and weight management. By balancing calories, individuals can ensure they are meeting their nutritional needs without overeating or consuming excess calories. A: Balancing sodium and potassium is important for managing blood pressure, but this is not a specific guideline of the ChooseMyPlate program. B: Decreasing water consumption is not a guideline of the ChooseMyPlate program. Adequate hydration is essential for overall health. C: Increasing portion size is not recommended in the ChooseMyPlate program. It emphasizes portion control and eating appropriate serving sizes of different food groups.

Correct Answer: C

Rationale: The correct answer is C: Assessing and addressing the patient's emotional needs. This should be prioritized because the patient has undergone a traumatic experience losing their eye due to a workplace accident. Emotions such as fear, anxiety, and grief are common postoperatively. Addressing these emotional needs is crucial for the patient's overall well-being and recovery. Options A, B, and D are important aspects of care but not the priority in this situation. Teaching about eye prostheses, depth perception, and medication regimen can be addressed once the patient's emotional needs are stabilized.

Correct Answer: C

Rationale: The correct answer is C because primary brain tumors originate from cells within the brain itself. These tumors develop from abnormal growth of brain cells. Choice A is incorrect as primary brain tumors do not come from outside the central nervous system (CNS). Choice B is incorrect as primary brain tumors do not typically start in glands. Choice D is incorrect as primary brain tumors do not arise from nerve tissue elsewhere in the body. In summary, the nurse should explain to the patient that the tumor originated from cells within his brain to provide accurate information about the nature of primary brain tumors.
