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.

Correct Answer: B

Rationale: The correct answer is B: higher rates of condom use among teenagers. This outcome indicates that the teenagers are adopting safer sexual practices, which can effectively reduce the incidence of STIs. Increased attendance at educational sessions (Choice A) may show interest but does not directly reflect behavior change. More teenagers seeking testing for STIs (Choice C) indicates awareness but not necessarily prevention. Greater knowledge of STI prevention methods (Choice D) is valuable but does not guarantee behavioral change like increased condom use.

Correct Answer: B

Rationale: The correct answer is B: Organizing free cholesterol screenings. This intervention is crucial because it helps identify individuals at risk for heart disease by assessing their cholesterol levels. High cholesterol is a significant risk factor for heart disease, and identifying it early can lead to timely interventions and medical care. Choices A, C, and D, while beneficial for overall health, may not directly address the specific risk factor of high cholesterol associated with heart disease. Distributing educational materials on heart-healthy diets (A) could be helpful in preventing heart disease, but identifying individuals already at risk is a more urgent need. Holding workshops on stress management (C) and partnering with local gyms for fitness classes (D) are important for overall health promotion but may not target the specific risk factor of high cholesterol as directly as organizing cholesterol screenings.

Correct Answer: D

Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.

Correct Answer: A

Rationale: The correct answer is A: 'Ptosis on the left eyelid.' Ptosis is the term used to describe an eyelid droop that covers a large portion of the iris, which may be caused by issues with the oculomotor nerve or eyelid muscles. Choice B, 'Nystagmus,' refers to involuntary eye movements and is not related to eyelid drooping. Choice C, 'Astigmatism,' is a refractive error affecting vision due to an irregularly shaped cornea or lens, not an eyelid condition. Choice D, 'Exophthalmos,' is a protrusion of the eyeball associated with conditions like hyperthyroidism, not eyelid drooping.
