A 6-month-old boy weighed 8 lbs. 2 oz. at birth. Understanding developmental milestones, what should the nurse caring for the child calculate his current weight as?
Approximately 18 lbs. 6 oz.
Approximately 14 lbs. 8 oz.
Approximately 24 lbs. 4 oz.
Approximately 16 lbs. 4 oz.
The Correct Answer is D
A. Approximately 18 lbs. 6 oz.:
This option represents an overestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is higher than the expected weight.
B. Approximately 14 lbs. 8 oz.:
This option represents an underestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is lower than the expected weight.
C. Approximately 24 lbs. 4 oz.:
This option represents a significant overestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is much higher than the expected weight.
D. Approximately 16 lbs. 4 oz.:
This option is the correct estimate based on doubling the birth weight of 8 lbs. 2 oz. It accurately reflects the expected weight of a 6-month-old child according to developmental milestones.

Correct Answer is ["25"]
Explanation
To calculate the drops per minute for an IV infusion, we need to use the following formula:
gtt/min = (volume x drop factor) / time
In this case, the volume is 50 mL, the drop factor is 20 gtt/mL, and the time is 40 minutes. Plugging these values into the formula, we get:
gtt/min = (50 x 20) / 40
gtt/min = 1000 / 40
gtt/min = 25
Therefore, the adolescent patient should receive 25 drops per minute of Cefazolin IV.
