Correct Answer: B

Rationale: Dizziness after hemodialysis can indicate hypovolemia, hypotension, or other complications that require immediate intervention to prevent further deterioration or adverse events. Weight gain of 2 pounds may not be immediately concerning post-hemodialysis. A blood pressure of 150/90 mm Hg is slightly elevated but may not require immediate intervention unless accompanied by symptoms. A heart rate of 88 beats per minute falls within the normal range and may not be an immediate cause for concern after hemodialysis.

Correct Answer: D

Rationale: Suctioning the tracheostomy is the priority action because it ensures a patent airway before proceeding with any other tracheostomy care interventions. This step helps clear secretions and maintain airway patency, which is crucial for the client's respiratory status. Removing the inner cannula, cleaning the stoma, or changing the tracheostomy ties can follow once the airway is clear. Therefore, options A, B, and C are secondary actions compared to suctioning the tracheostomy.

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: The correct answer is A: motor vehicle accidents. Motor vehicle accidents are a significant cause of spinal cord injuries among adolescents due to the high impact forces involved. While violent assault, sports injuries, and falls can also lead to spinal cord injuries, statistics show that motor vehicle accidents are a leading cause in this age group. Educating adolescents about the risks and preventive measures related to motor vehicle accidents is crucial in promoting their safety and well-being.

Correct Answer: C

Rationale: A temperature of 99°F (37.2°C) in a postoperative client requires immediate intervention as it may indicate the presence of infection. Elevated temperature post-surgery can be a sign of surgical site infection or systemic infection, which can lead to serious complications if not addressed promptly. Monitoring and managing a fever in a postoperative client is crucial to prevent further complications. The other findings, such as a heart rate of 90 beats per minute, oxygen saturation of 92%, and pain at the surgical site, are common postoperative assessments that may not necessarily require immediate intervention unless they are significantly out of normal range or causing severe distress to the client.
