A client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?
- A. Petechiae on the chest and abdomen
- B. WBC 16,000/mm3
- C. Negative throat culture
- D. Severe hyperemia of pharyngeal mucosa
Correct Answer: C
Rationale: The correct answer is C, negative throat culture. In viral pharyngitis, the infection is caused by a virus, not bacteria. Therefore, a throat culture would be negative as it tests for bacterial infection. Option A is incorrect as petechiae are more commonly seen in conditions like meningococcal sepsis. Option B is incorrect as a WBC count of 16,000/mm3 is more indicative of a bacterial infection. Option D is incorrect as severe hyperemia of the pharyngeal mucosa is more typical of bacterial pharyngitis, not viral.

A healthcare professional is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the healthcare professional expect?
- A. Bradycardia
- B. Bradypnea
- C. Lethargy
- D. Intercostal retractions
Correct Answer: D
Rationale: The correct answer is D: Intercostal retractions. In postoperative atelectasis, there is a collapse of lung tissue leading to decreased oxygen exchange and hypoxia. Intercostal retractions indicate increased work of breathing as the body tries to compensate for the decreased lung function. Bradycardia and bradypnea are not typically associated with hypoxia but rather with decreased oxygen delivery to tissues. Lethargy is a nonspecific symptom and may not directly correlate with hypoxia in this scenario.
