A nurse is assisting in the admission of a client who has measles. Which of the following isolation precautions should the nurse initiate?

Choice A rationale:
Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by dehydration and electrolyte imbalances, and fluid replacement is a crucial aspect of its management. Restricting fluids could worsen dehydration and hinder the correction of metabolic imbalances.
Choice B rationale:
(Correct Choice) Monitoring vital signs every 8 hours is an important intervention for a school-age child with DKA. Vital signs, including heart rate, respiratory rate, blood pressure, and temperature, provide valuable information about the child's overall condition, fluid status, and response to treatment. More frequent monitoring might be necessary during the acute phase of DKA.
Choice C rationale:
Initiating continuous cardiac monitoring is not typically indicated for a school-age child with DKA. While DKA can have effects on the cardiovascular system, continuous cardiac monitoring is reserved for more critical situations where immediate changes in heart rhythm need to be detected.
Choice D rationale:
Administering subcutaneous insulin 30 minutes before meals is not appropriate for a child with DKA. In DKA management, insulin is typically administered intravenously to achieve more precise control over blood glucose levels. Subcutaneous insulin might not provide the rapid and consistent action needed to address the acute hyperglycemia and metabolic acidosis in DKA.

The correct answer is choice C. 6.8 to 7.7 kg (15 to 17 lb).

Choice A rationale:

This weight range is above the average for a 6-month-old infant. According to growth charts, the 50th percentile weight for a 6-month-old male is approximately 7.9 kg (17 lb 8 oz), and for a female, it’s about 7.3 kg (16 lb 1 oz). Therefore, 8.6 to 9.5 kg would be considered above average and not the anticipated weight for most infants.

Choice B rationale:

This weight range is below the average for a 6-month-old infant. The average weight at 6 months is significantly higher than 4.1 to 5 kg, as infants are expected to double their birth weight by 5 months of age. Therefore, an infant weighing between 9 to 11 lb at 6 months would be considered underweight.

Choice C rationale:

This weight range is within the average for a 6-month-old infant. As mentioned, the 50th percentile weights for 6-month-old infants are approximately 7.9 kg for males and 7.3 kg for females. This choice falls within the expected weight gain trajectory where an infant is anticipated to double their birth weight by 5 months and then gain an additional pound or so by 6 months.

Choice D rationale:

This weight range is significantly above the average for a 6-month-old infant. It is well above the 95th percentile for this age group and would be considered unusual without underlying health conditions that could contribute to such a weight at this age. An infant weighing between 23 to 25 lb at 6 months would be exceptionally rare and likely indicative of an abnormal growth pattern.
