Correct Answer: B

Rationale: The correct answer is B: Montelukast (Singulair). Montelukast is a leukotriene receptor antagonist that helps prevent asthma exacerbations by reducing inflammation in the airways. It is used as a maintenance medication to control and prevent asthma symptoms. Diphenhydramine (A) is an antihistamine used for allergies, not asthma prevention. Albuterol sulfate (C) is a rescue inhaler used for acute asthma symptoms, not prevention. Epinephrine (D) is used for severe allergic reactions (anaphylaxis), not asthma prevention.

Correct Answer: D

Rationale: The correct answer is D: Lithotomy position. In lithotomy position, the patient's legs are elevated and positioned higher than the heart, which can lead to venous stasis and increase the risk of deep vein thrombosis (DVT). This position compresses the femoral veins, hindering blood flow and predisposing the patient to DVT formation. Summary: A: Fowlers position - Not typically associated with increased DVT risk. B: Prone position - Not typically associated with increased DVT risk. C: Supine position - Generally considered a safe position regarding DVT risk.

Correct Answer: A

Rationale: The correct answer is A because it addresses the key issue of perception of risk among older adults. Many older adults may not perceive themselves as being at risk for HIV infection due to misconceptions or lack of awareness. This principle guides the nurse to tailor educational interventions to address this specific barrier. Choices B, C, and D are incorrect as they do not directly address the perception of risk among older adults. Older adults' awareness of HIV/AIDS, number of sex partners, or incidence of intravenous drug use are not the primary factors influencing their perception of HIV risk.

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

Correct Answer: D

Rationale: The correct answer is D - The patient will benefit from a low-protein diet. Patients with Huntington disease often experience difficulty swallowing and may have involuntary movements, leading to weight loss. A low-protein diet can help manage these symptoms and reduce the risk of aspiration pneumonia. This diet can also help control the chorea movements associated with the disease. Choice A is incorrect as patients with Huntington disease often have reduced appetite due to swallowing difficulties. Choice B is incorrect as enzyme supplements are not typically indicated in the management of Huntington disease. Choice C is incorrect as a clear liquid diet is not suitable for meeting the nutritional needs of a patient with Huntington disease, who may already be at risk for malnutrition.
