Acyclovir (Zovirax) is the agent of choice for which of the following infections?

Correct Answer: D

Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.

Correct Answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

Correct Answer: A

Rationale: When assessing a client with a cast, it is crucial to check for capillary refill to ensure adequate circulation. Warm toes indicate good circulation, while the absence of discomfort suggests the cast is not causing any pain or undue pressure on the client. Therefore, choices B, C, and D are incorrect as they do not address the essential components of assessing a client with a cast.

Correct Answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

Correct Answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.

Correct Answer: B

Rationale: The correct answer is to promote healthy nutritional practices. This goal focuses on preventive measures to address the client's nutritional risk. Providing oxygen (Choice A) is not directly related to addressing nutritional problems. Treating complications of malnutrition (Choice C) involves addressing the consequences rather than preventing or managing the nutritional problems. Increasing weight (Choice D) would only be appropriate if the client is underweight; it does not address the broader aspect of promoting overall healthy nutritional practices.

Correct Answer: D

Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.

Correct Answer: D

Rationale: The most appropriate nursing diagnosis for Mrs. Peterson is 'Sleep Pattern Disturbances (related to chronic leg pain).' Mrs. Peterson's sleep issues are directly linked to her chronic leg pain, which is a result of her arthritis. This nursing diagnosis addresses the primary cause of her sleep disturbances and allows for interventions that focus on managing the pain to improve her sleep. Choices A, B, and C are incorrect. Choice A correctly identifies the relationship between sleep disturbances and chronic leg pain, addressing the root cause. Choice B is incorrect as it only focuses on fatigue and does not encompass the broader sleep issues. Choice C is not relevant as there is no indication that Mrs. Peterson lacks knowledge about sleep hygiene measures.

Correct Answer: C

Rationale: A risk management program within a hospital is responsible for identifying risks, controlling financial loss due to malpractice claims, and analyzing risks and trends to guide further interventions or programs. It is not responsible for ensuring that staff follow their job descriptions. Monitoring staff adherence to their job descriptions falls under the purview of departmental managers or supervisors. The primary focus of a risk management program is to assess, mitigate, and manage risks related to patient safety, quality of care, and financial implications, rather than overseeing staff job descriptions.
