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.

Answer and Explanation

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 ["0.1696"]

Explanation

To calculate the ordered dose by the physician in mg/kg/dose, we need to convert the infant's weight from pounds and ounces to kilograms. One pound is equal to 0.4536 kg and one ounce is equal to 0.02835 kg. Therefore, the infant's weight in kilograms is:

6 x 0.4536 + 3 x 0.02835 = 2.948 kg

The ordered dose by the physician is 0.5 mg IV q 2 hours prn. To find the dose in mg/kg/dose, we divide the dose in mg by the weight in kg:

0.5 / 2.948 = 0.1696 mg/kg/dose

The recommended dosage for a child is 0.1-0.2 mg/kg/dose q2-4 hours prn. The ordered dose by the physician falls within this range, so it is a safe dosage for the infant.

A. “We will keep our household hot water heater at 130 degrees.” B. “We will place poisonous substances in a high cupboard.” C. “We will place a gate at the top and bottom of stairways.” D. “We will put plastic fillers in all electrical plugs.” E. “We will turn handles of pans on the stove toward the back of the stove.”

Correct Answer is ["B","C","D","E"]

Explanation

A. “We will keep our household hot water heater at 130 degrees.”

The recommended setting for a hot water heater is typically 120 degrees Fahrenheit to prevent scalds. Setting it at 130 degrees may still pose a risk of burns to young children.

B. “We will place poisonous substances in a high cupboard.”

Placing poisonous substances out of reach in a high cupboard is a safety measure to prevent children from accessing potentially harmful substances.

C. “We will place a gate at the top and bottom of stairways.”

Using safety gates at the top and bottom of stairways is an effective way to prevent young children from falling down stairs.

D. “We will put plastic fillers in all electrical plugs.”

Placing plastic fillers in electrical plugs helps prevent children from inserting objects into outlets, reducing the risk of electric shock.

E. “We will turn handles of pans on the stove toward the back of the stove.”

Turning handles of pans on the stove toward the back is a safety measure to prevent young children from reaching up and pulling hot items off the stove.
