In assessing a 2-year-old boy with croup, the practical nurse (PN) finds that he has become increasingly irritable and has developed tachypnea and resting stridor. Which intervention is best for the PN to implement?

The correct answer is choice B: Culture for sensitive organisms.

• Choice A rationale:
• C-reactive protein level - C-reactive protein (CRP) is a blood test marker for inflammation in the body. While it could indicate an infection, it is not specific enough to identify the type of infection or the causative organism.
• Choice B rationale:
• Culture for sensitive organisms - When a wound has a moderate amount of yellow and green drainage and a foul odor, it is often a sign of a bacterial infection. A culture for sensitive organisms can help identify the specific bacteria causing the infection, which is crucial for determining the most effective treatment.
• Choice C rationale:
• Serum albumin - Serum albumin levels can indicate a person’s nutritional status. Low levels can slow wound healing, but they do not directly indicate the presence of an infection.
• Choice D rationale:
• Serum blood glucose (BG) level - High blood glucose levels can impair the immune response and slow wound healing, making a person more susceptible to infections. However, like CRP, it does not provide information about the specific organism causing the infection.

The correct answer is Choice C:

Suggest that an increase in fruits and vegetables is more beneficial.

Choice C rationale:

While dairy products do provide essential nutrients like calcium and vitamin D, there is no strong evidence to suggest that increasing dairy intake alone will significantly reduce the risk of cancer. On the other hand, fruits and vegetables are known to be rich in antioxidants and phytochemicals that have been associated with a reduced risk of cancer. Therefore, suggesting an increase in fruits and vegetables is a more evidence-based approach to reducing cancer risk.

Choice A rationale:

Encouraging exercise is a good recommendation for overall health, but it does not directly address the client's concern about reducing cancer risk. Focusing on a balanced diet, including plenty of fruits and vegetables, is more relevant to the client's specific concern.

Choice B rationale:

Reminding the client about Vitamin D-fortified dairy products may be helpful for addressing Vitamin D intake, but it doesn't necessarily address the broader concern of reducing cancer risk. Moreover, the link between dairy and cancer risk reduction is not as well-established as the benefits of fruits and vegetables.

Choice D rationale:

Providing information about cancer warning signs is important for cancer awareness but doesn't address the client's current dietary choices and concerns about cancer prevention. The focus should be on evidence-based dietary recommendations to reduce cancer risk.
