A parent of an 8-month-old asks the nurse how it will be determined whether their child has respiratory syncytial virus (RSV). Which is the nurse's best answer?

"We will do a simple blood test."

"We will swab you child's nose and send the specimen for testing."

"We will have to sedate your child and do a CT scan of his chest."

“There is no specific test for RSV."

Answer and Explanation

The Correct Answer is B

A. "We will do a simple blood test. A blood test may show signs of infection, such as elevated white blood cells, but it cannot confirm RSV. It is not a specific or reliable method for diagnosing respiratory syncytial virus in infants.

B. "We will swab your child’s nose and send the specimen for testing. Nasopharyngeal swabs are commonly used to detect RSV using antigen detection or polymerase chain reaction (PCR) testing. The procedure is non-invasive, and highly specific for diagnosing RSV.

C. "We will have to sedate your child and do a CT scan of his chest." CT scans are not used to diagnose RSV and carry unnecessary risk, especially with sedation in infants. Imaging is reserved for complicated or atypical cases and does not confirm viral etiology.

D. “There is no specific test for RSV." There are several reliable tests available for detecting RSV, including rapid antigen tests and PCR from nasal secretions. Accurate testing is important for confirming diagnosis and preventing transmission.

Correct Answer is D

Explanation

A. Blood pressure of 138/84 mmHg:This is within the acceptable range for a 68-year-old adult, especially with a history of hypertension. It does not indicate an acute threat or require immediate intervention in the context of pneumonia.

B. WBC count of 15,000/mm³:An elevated WBC count is expected in response to infection, such as pneumonia. While it confirms an inflammatory process, it is not the most urgent issue requiring immediate nursing action.

C. Blood glucose of 198 mg/dL:This mild hyperglycemia is not uncommon in infections and stress responses, particularly in patients with diabetes. It should be monitored, but it is not an immediate danger to the patient.

D. Oxygen saturation 89%:This low oxygen saturation indicates hypoxemia and impaired gas exchange, which is critical in a patient with pneumonia. Immediate oxygen therapy is necessary to prevent tissue hypoxia and respiratory failure.

A. lint-free pipe cleaner B. The inner cannula does not need to be dried before reinserting it into the outer cannula. C. Q-tip D. medical air

Correct Answer is A

Explanation

A. Lint-free pipe cleaner:A lint-free pipe cleaner is ideal for drying the inner cannula because it won’t introduce fibers or debris into the airway. It ensures that the cannula is thoroughly dried without increasing the risk of aspiration or airway irritation from lint.

B. The inner cannula does not need to be dried before reinserting it into the outer cannula:Moisture left inside the cannula can promote bacterial growth and lead to infection. Drying the cannula is an essential step to prevent microbial contamination and to maintain patency and safety.

C. Q-tip:Q-tips can shed fibers and are not suitable for internal tracheostomy components. Using them may lead to lint being introduced into the airway, increasing the risk of irritation or infection.

D. Medical air:Medical air is not used to dry tracheostomy components. It is not practical, and it may not fully dry narrow internal surfaces. Manual drying with a lint-free material is safer and more effective.
