Correct Answer: D

Rationale: The correct answer is D: greater use of contraception among teens. This outcome indicates successful prevention of pregnancies by demonstrating that teens are taking proactive steps to avoid unintended pregnancies. Increased attendance at health education classes (choice A) may show improved knowledge but does not directly measure the prevention of pregnancies. While a decreased number of repeat pregnancies among teens (choice B) is positive, it does not necessarily indicate prevention of initial pregnancies. A higher number of teens seeking prenatal care (choice C) is important for maternal and fetal health but does not directly reflect the prevention of teen pregnancies.

Correct Answer: A

Rationale: Lethargy is a critical finding that requires the nurse's immediate attention when a client with a recent skull fracture is readmitted to the hospital. It can indicate increased intracranial pressure or other serious complications such as hemorrhage or infection. Addressing lethargy promptly is crucial to prevent further deterioration. Agitation, ataxia, and hearing loss are important to assess but do not signify the same level of urgency as lethargy in this context.

Correct Answer: C

Rationale: Ascites is a common finding in clients with portal hypertension. Portal hypertension results in increased pressure in the portal vein, leading to the development of ascites, which is the accumulation of fluid in the abdominal cavity. Expiratory wheezes (Choice A) are associated with respiratory conditions. Blurred vision (Choice B) is more commonly linked to eye disorders or neurological issues. Dilated pupils (Choice D) can be related to neurological conditions or drug effects, but not specifically to portal hypertension.

Correct Answer: D

Rationale: A decrease in chest wall expansion suggests that the client may be experiencing a serious complication, such as worsening pneumonia or respiratory failure, requiring immediate medical attention. This finding indicates a potential decrease in lung function, which could lead to respiratory distress. Pleuritic pain on inspiration may be related to the disease process but does not indicate an immediate need for intervention. Dry mucus membranes in the mouth may require attention but are not as critical as a decrease in chest wall expansion. A decrease in respiratory rate could be concerning but is not as urgent as a decrease in chest wall expansion, which directly impacts respiratory function.

Correct Answer: C

Rationale: Studying knowledge, attitudes, and practices of the people is the best method to determine appropriate health teaching for a community. This approach provides valuable insights into the specific needs, beliefs, and behaviors of the population, allowing for tailored and effective health education interventions. Interviewing midwives may offer some insights, but focusing on the broader community is more comprehensive. Reviewing records and reports can provide historical data but may not capture current community needs as effectively as studying current knowledge, attitudes, and practices. Reviewing health statistics is important but may not provide the detailed understanding of community perceptions and behaviors that directly impact health education planning.
