Correct Answer: C

Rationale: Confusion is a common manifestation of pneumonia in older adults. It can result from inadequate oxygenation to the brain due to respiratory compromise. Bradycardia, night sweats, and narrowed pulse pressure are not typically specific findings associated with pneumonia and should be further assessed or monitored, but confusion is a key indicator that warrants immediate attention.

Correct Answer: D

Rationale: In an asthma action plan, the yellow zone indicates caution and signals a need to monitor symptoms closely. When a student is in the yellow zone, the appropriate action is to follow the prescribed steps, which typically include using a quick-relief inhaler and closely monitoring peak flow. Going to the hospital is usually reserved for severe asthma exacerbations in the red zone. Therefore, the information that the student needs to go to the hospital is not typically appropriate when the student is in the yellow zone.

Correct Answer: C

Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.

Correct Answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.
