Correct Answer: C

Rationale: Pregnant women should be prioritized for flu vaccination as they are at higher risk for complications from the flu. During pregnancy, changes in the immune, heart, and lung functions make pregnant women more susceptible to severe illness from the flu. Vaccinating pregnant women not only protects them but also provides passive immunity to their newborns. Children under 5, adults aged 50-65, and healthcare workers are important groups for vaccination but do not have the same level of increased risk for flu complications as pregnant women.

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: In renal failure and osteodystrophy, there is an alteration in serum electrolyte balance. The correct answer is serum potassium of 5.5 mEq/L and total calcium of 6 mg/dL. Renal failure is associated with hyperkalemia (elevated serum potassium) and hypocalcemia (low total calcium levels). Hyperphosphatemia is also commonly seen in renal failure. Choice A is incorrect as it describes normal levels of serum potassium and total calcium. Choice B is unrelated to the client's condition. Choice D is incorrect as it does not reflect the typical electrolyte imbalances seen in renal failure and osteodystrophy.

Correct Answer: A

Rationale: Prioritizing the benefits of immunizations is crucial in helping parents comprehend the significance of vaccines in safeguarding their children against preventable diseases. Understanding the positive impact of immunizations can alleviate concerns and misconceptions that parents may have, ultimately encouraging them to make informed decisions regarding their children's health. Discussing potential side effects (choice B) is important but should come after highlighting the benefits to avoid instilling unnecessary fear. While the immunization schedule (choice C) is essential information, it may be overwhelming if presented as the initial focus. Comforting children during vaccinations (choice D) is valuable but secondary to ensuring parents understand the benefits of immunizations.

Correct Answer: C

Rationale: The correct answer is C: reduced rates of childhood obesity. A reduction in childhood obesity rates is a direct indicator that the program is successful in achieving its goal. Increased participation in physical activities (choice A) and higher attendance at nutrition education sessions (choice B) are positive outcomes, but they do not directly measure the program's effectiveness in reducing obesity. Greater knowledge of healthy eating habits (choice D) is important but does not guarantee a decrease in obesity rates. Therefore, the most significant outcome to determine the success of a childhood obesity reduction program is a reduction in obesity rates.
