Correct Answer: A

Rationale: Offering vaccinations at convenient locations and times is the most effective intervention as it reduces barriers to access and makes it easier for parents to get their children vaccinated. This strategy directly addresses the issue of convenience and accessibility, which are common reasons for low vaccination rates. Distributing educational materials about vaccines (Choice B) can be helpful but may not directly address access issues. Providing incentives for getting vaccinated (Choice C) may be controversial and not sustainable in the long term. Hosting informational sessions for parents (Choice D) can be beneficial for education but may not directly improve vaccination rates as much as increasing access.

Correct Answer: C

Rationale: The correct intervention for a client with a platelet count of 20,000/mm3 due to chemotherapy is to avoid invasive procedures. Chemotherapy can cause a decrease in platelet count, leading to an increased risk of bleeding. By avoiding invasive procedures, the nurse helps reduce the risk of bleeding complications. Applying ice packs to bruised areas (Choice A) may further increase the risk of bleeding due to the pressure and potential trauma to the skin. Encouraging frequent oral hygiene (Choice B) is important for overall health but does not directly address the risk of bleeding associated with a low platelet count. Placing the client in a private room (Choice D) is not directly related to managing the platelet count and risk of bleeding; it is more about privacy and infection control, which are important but not the priority in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Absence of breath sounds. This finding is concerning in a client with asthma as it may indicate a severe asthma exacerbation, airway obstruction, or pneumothorax, all of which require immediate intervention. Absence of breath sounds suggests a lack of airflow in the lungs, which is a critical sign that should prompt immediate action. Expiratory wheezes (choice A) are common in asthma and may not warrant immediate intervention unless severe. An increased respiratory rate (choice B) is expected in a client with asthma experiencing shortness of breath, but it does not indicate an immediate threat to the airway. Frequent coughing (choice D) is a common symptom in asthma exacerbations but does not signify an immediate need for intervention as it can be managed with appropriate asthma treatments.

Correct Answer: C

Rationale: The most critical factor to evaluate when assessing a community's readiness for a smoking cessation program is the community's attitude towards smoking. Understanding the community's perceptions, beliefs, and behaviors related to smoking is crucial as it helps determine the level of receptiveness and potential success of the program. Assessing smoking rates (Choice A) could provide valuable epidemiological data but may not reflect the community's readiness for change. While the availability of smoking cessation resources (Choice B) is important, without considering the community's attitude, the program's effectiveness may be limited. Local healthcare providers' support (Choice D) is valuable but secondary to the community's attitude, which directly influences the program's acceptance and impact.

Correct Answer: A

Rationale: Surveying employees to determine how many are smoking 2 months after the end of the program provides a direct assessment of the program's effectiveness. This measurement evaluates the actual behavior change related to smoking cessation. Choice B, testing knowledge of OTC nicotine substitute products, does not directly measure smoking cessation outcomes. Choice C relies on self-reporting, which may not be accurate or reliable. Choice D focuses on identifying lifestyle changes but does not directly assess the program's impact on smoking cessation.
