Correct Answer: D

Rationale: Vaccines are crucial in preventing communicable diseases. Smallpox has been eradicated globally, so its vaccine is no longer used. Polio, pertussis, and measles are diseases that are controlled by routine childhood immunization. While smallpox has been eradicated, these diseases still exist, making it essential for children to be vaccinated against them. Choices A, B, and C include diseases that are not prevented by vaccination or are not related to routine immunizations, making them incorrect choices.

Correct Answer: D

Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.

Correct Answer: A

Rationale: For stress incontinence, advising the client to consider trying Kegel exercises is appropriate. Kegel exercises involve tightening and releasing the pelvic floor muscles, which can improve stress incontinence by strengthening the muscles that control urination. Choice B suggesting immediate surgery is incorrect as surgery is usually considered after conservative treatments like Kegel exercises have been tried. Choice C advising to avoid all forms of treatment is dangerous and neglectful. Choice D recommending to ignore the issue is inappropriate as it can impact the client's quality of life and may worsen over time without intervention.

Correct Answer: D

Rationale: Vaccines are crucial in preventing communicable diseases. Smallpox has been eradicated globally, so its vaccine is no longer used. Polio, pertussis, and measles are diseases that are controlled by routine childhood immunization. While smallpox has been eradicated, these diseases still exist, making it essential for children to be vaccinated against them. Choices A, B, and C include diseases that are not prevented by vaccination or are not related to routine immunizations, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is B: secondary prevention. This type of prevention focuses on reducing the impact of a disease by early detection and treatment. In the case of gonorrhea, teaching the client how to prevent reinfection and further spread falls under secondary prevention because it aims to reduce the prevalence and morbidity of the disease. Choice A (primary prevention) involves measures to prevent the disease from occurring in the first place, such as vaccination. Choice C (tertiary prevention) focuses on managing the long-term consequences of a disease to prevent complications. Choice D (primary health care prevention) is not a recognized term in prevention strategies.
