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

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.

Choice A rationale:
Cleaning the infant's suture line with chlorhexidine solution is not indicated immediately after cleft lip repair. The primary concern in the immediate postoperative period is pain management and wound healing, and cleaning the suture line with chlorhexidine could potentially disrupt the healing process.
Choice B rationale:
Applying elbow immobilizers to the infant is not necessary after cleft lip repair. Elbow immobilizers are typically used in situations where there's a need to restrict arm movement, such as preventing a child from bending their arms after certain types of surgery. Cleft lip repair does not involve the arms, so this action is not relevant.
Choice C rationale:
Correct Choice. Offering the infant a pacifier with sucrose for pain relief is appropriate. Non-nutritive sucking, such as using a pacifier, has been shown to have pain-relieving effects in infants. Sucrose, a sweet solution, is often used in combination with non-nutritive sucking to further enhance pain relief during minor procedures or painful experiences. It provides comfort and distraction to the infant, helping to reduce their discomfort.
Choice D rationale:
Placing the infant in a prone position for sleeping is contraindicated after cleft lip repair. Placing an infant prone (on their stomach) for sleep increases the risk of sudden infant death syndrome (SIDS). The recommended sleep position for infants is supine (on their back) to ensure their safety.
