A nurse is preparing to administer erythromycin ethylsuccinate 800 mg PO every 4 hr. Available is erythromycin ethylsuccinate 200 mg/5mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["20"]
To administer the correct dose of erythromycin ethylsuccinate, which is 800 mg, when the available medication concentration is 200 mg per 5 mL, the nurse needs to calculate the volume of medication to provide the prescribed dose. The calculation is as follows: 800 mg divided by 200 mg equals 4. Then, multiply 4 by 5 mL to get the total volume needed for the 800 mg dose. Therefore, the nurse should administer 20 mL of erythromycin ethylsuccinate to deliver the prescribed 800 mg dose.

Correct Answer is C
Explanation
A. While heart failure can occur in many congenital heart defects, it is not the most specific condition commonly associated with tetralogy of Fallot.
B. Asthma is not typically associated with tetralogy of Fallot. It is a respiratory condition that does not have a direct link to congenital heart defects.
C. Tetralogy of Fallot is associated with polycythemia due to chronic hypoxemia. The body produces more red blood cells in response to low oxygen levels, leading to an increased hematocrit.
D. While pulmonary hypertension can occur in congenital heart defects, tetralogy of Fallot is more directly associated with polycythemia as a result of the decreased blood flow to the lungs.
Correct Answer is A
Explanation
A. The FLACC scale (Face, Legs, Activity, Cry, Consolability) is designed for infants and young children who cannot verbally communicate their pain, making it suitable for a 2-month-old.
B. The FACES scale is used for older children who can point to or choose faces that represent their pain level and is not suitable for a 2-month-old.
C. The OUCHER scale is used for children aged 3 to 13 years and includes pictures representing pain, so it is not appropriate for a 2-month-old.
D. The PANAD scale is not a standard pain rating scale used for infants and is less commonly used than the FLACC scale.
