Which is the treatment of choice for severe aplastic anemia?

A. Obtaining a throat culture and B. visualizing the epiglottis with a tongue depressor are not safe actions for the nurse to perform without appropriate medical equipment and expertise. These actions can trigger a sudden airway obstruction in a child with epiglottitis. The priority is to ensure airway patency and seek immediate medical assistance.

C. Place the child in an upright position.

Suspected epiglottitis is a medical emergency that can result in rapid airway obstruction. Placing the child in an upright position helps improve airflow by allowing the throat to open and reduces the risk of complete airway obstruction. It's important not to perform invasive procedures (such as throat culture or visualization of the epiglottis) without proper medical equipment and expertise, as these actions can lead to worsening airway obstruction.

D. Transporting the child to radiology for a throat x-ray is not appropriate in this situation, as it may delay necessary interventions to secure the airway.

A.Altered level of consciousness and thready pulse.

In a child after heart surgery to correct Tetralogy of Fallot (TOF), a thready pulse and altered level of consciousness can be indicative of poor cardiac output. This may suggest that the heart is not effectively pumping blood to meet the body's needs.

B. Bounding pulses and mottled skin: Bounding pulses and mottled skin are not typical signs of decreased cardiac output. Bounding pulses are often associated with increased cardiac output.

C. Capillary refill of 2 seconds and blood pressure of 96/47 mmHg: A capillary refill of 2 seconds is within the normal range, and a blood pressure of 96/47 mmHg is reasonable for a child. These findings do not necessarily indicate poor cardiac output.

D. Extremities warm to the touch and pale skin: Warm extremities and pale skin are not typical signs of decreased cardiac output. Cold extremities and cyanosis may be more concerning signs.
