A school-age child is admitted to the ER with status asthmaticus. The parent states the child is taking montelukast, albuterol, and fluticasone. Which is the most important piece of information that the nurse needs to ask the parent to best treat the child?

"Has your child been exposed to any of the usual asthma triggers?"

"What time did your child's symptoms begin?"

"When was your child's last dose of medication?"

"When was your child last admitted to the hospital with asthma?"

Answer and Explanation

The Correct Answer is C

A.   While this information is important for understanding the cause of the asthma exacerbation, it is not the most critical piece of information needed for immediate treatment.
B.   Knowing when the symptoms began can help determine the severity of the exacerbation and the need for additional interventions. However, it is not as important as knowing the last dose of medication.
C.   This information is crucial for determining the appropriate treatment. If the child has not received their regular medications as prescribed, they may need additional doses to manage the exacerbation.
D.   Knowing the child's history of asthma exacerbations is important for assessing the severity of the current episode and planning long-term management. However, it is not the most critical piece of information needed for immediate treatment.

Correct Answer is B

Explanation

A. The ASO titer is a blood test used to detect streptococcal infections, particularly post-streptococcal sequelae like rheumatic fever or glomerulonephritis. It is not related to tuberculosis.
B. The Purified Protein Derivative (PPD) test, also known as the tuberculin skin test (TST), is specifically used to identify exposure to the tuberculosis bacteria. If a person has been exposed, the immune system will react to the PPD injection, causing a localized skin reaction that can be measured after 48-72 hours.
C. While a chest X-ray is an important tool for diagnosing active tuberculosis or assessing lung involvement, it is not the initial test for determining exposure to TB. It is usually ordered after a positive PPD test or when there are clinical symptoms of TB.
D. C-reactive protein (CRP) is a nonspecific marker of inflammation and infection in the body. It does not specifically indicate exposure to tuberculosis and is not used for TB testing.

Correct Answer is ["400"]

Explanation

Total volume = 100 mL

Time = 15 minutes = 0.25 hours (15 minutes / 60 minutes/hour)

Infusion rate = Total volume / Time Infusion rate = 100 mL / 0.25 hours Infusion rate = 400 mL/hour

Therefore, the nurse should set the IV infusion pump to 400 mL/hour.
