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.)

Answer and Explanation

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","D"]

Explanation

A. Contact precautions are not indicated unless there is an infectious disease concern, which is not mentioned in this scenario.

B. Head circumference is routine for well-baby visits and neurological conditions (e.g., hydrocephalus). It is not related to pyloric stenosis assessment.

C. Regular weighing is crucial to assess for weight loss due to vomiting and dehydration. Monitoring weight helps evaluate the severity of the infant's condition and the effectiveness of ongoing treatment.

D. Tracking intake and output is essential for managing hydration status and ensuring the infant is receiving adequate fluids. It helps in assessing the balance between fluid loss due to vomiting and fluid replacement.

E. This intervention is not appropriate for hypertrophic pyloric stenosis. The primary treatment for this condition is surgical intervention, and feeding changes alone will not resolve the underlying issue.

F. The FACES scale is typically used for older children who can self-report pain. For an infant, alternative pain assessment methods would be used, such as observing behavioral cues.

G. An enema is not indicated for hypertrophic pyloric stenosis and may worsen the infant's condition. The focus should be on hydration and surgical preparation rather than enemas.

A. Prepare for seizures. B. Expect the skin to turn yellow. C. Encourage progressive activity. D. Prevent dehydration

Correct Answer is D

Explanation

A. Seizures are not a typical complication of polycythemia, though they may occur if the condition progresses to severe levels of blood viscosity.

B. Yellowing of the skin (jaundice) is not associated with polycythemia but with liver conditions.

C. While activity is important, preventing dehydration is more critical in managing polycythemia because dehydration increases blood viscosity, exacerbating the condition.

D. Preventing dehydration is essential as it helps maintain adequate blood flow and reduces the risk of thrombotic events in a child with polycythemia.
