Which lab value is a cause for concern that the nurse should report to the healthcare provider?

HCT=50

RBC= 4.5

WBC= 2

Platelets=325,000

Answer and Explanation

The Correct Answer is C

A. HCT = 50: Hematocrit of 50% may be slightly elevated, but is not immediately dangerous and could be normal in dehydration.

B. RBC = 4.5: This value is within normal range for most children and adults, so not concerning.

C. WBC = 2: A WBC of 2 (2,000/mm³) indicates leukopenia, increasing risk of infection. This is especially concerning in immunocompromised or post-chemotherapy clients.

D. Platelets = 325,000: This value is within the normal range (150,000–450,000), so not a cause for concern.

Correct Answer is A

Explanation

A. have a tracheotomy set at the bedside. Acute epiglottitis is a medical emergency due to the risk of sudden airway obstruction. Manipulating the throat may trigger complete airway blockage. Emergency airway equipment must be available.
B. restrain the child's arms. Restraint can worsen anxiety and possibly exacerbate airway obstruction.
C. immobilize the child's head. This is not a priority and may interfere with breathing efforts.
D. have oxygen available. While oxygen is important, having emergency airway support (e.g., tracheotomy) is the priority in case of airway collapse.

A. Initiate airborne precautions. B. Apply humidified oxygen via a mask. C. Use a tongue depressor to observe the back of the throat. D. Attempt to obtain a throat culture.

Correct Answer is B

Explanation

A. Initiate airborne precautions: Epiglottitis is transmitted via droplets, so droplet precautions are sufficient, not airborne isolation.
B. Apply humidified oxygen via a mask: Provides oxygenation and helps moisturize the airway, which is essential in epiglottitis while minimizing distress.
C. Use a tongue depressor to observe the back of the throat: This may trigger complete airway obstruction and is contraindicated in suspected epiglottitis.
D. Attempt to obtain a throat culture: Like the tongue depressor, this may provoke laryngospasm or airway blockage-throat inspection is avoided until the airway is secured.
