A nurse is assessing a 12-month-old infant who is brought to the clinic by the parents for a well-child visit. The nurse reviews the infant's health history and notes that the infant weighed 8 lb at birth. When assessing the infant's weight at this visit, the nurse would anticipate that the infant would weigh approximately how much at this time?

Answer and Explanation

The Correct Answer is C

A. 20 lbs: This is a plausible estimate. By 12 months, an infant's birth weight typically triples. Therefore, an 8 lb birth weight would approximately translate to 24 lbs at 12 months.

B. 32 lbs: This estimate is too high. If an infant's birth weight triples by 12 months, an 8 lb birth weight would not be expected to reach 32 lbs.

C. 24 lbs: An infant's weight usually triples by their first birthday. Therefore, an infant born weighing 8 lbs would be expected to weigh about 24 lbs at 12 months.

D. 16 lbs: This is an underestimate. An 8 lb infant would double their birth weight by about 4 to 6 months, and by 12 months, they would typically have tripled their birth weight to around 24 lbs.

Correct Answer is A

Explanation

A. Ask the client to read a Snellen chart: Cranial nerve II (Optic nerve) is responsible for vision. Assessing the client's ability to read a Snellen chart tests visual acuity, which is a function of cranial nerve II.

B. Listen to the client's speech: This assesses cranial nerves V (Trigeminal) and VII (Facial), which are involved in speech and facial sensation.

C. Ask the client to clench his teeth: This assesses cranial nerve V (Trigeminal), which controls jaw movement and sensation.

D. Ask the client to identify scented aromas: This assesses cranial nerve I (Olfactory), which is responsible for the sense of smell.

A. Bend at the knees when picking up an object. B. Relax her abdominal muscles when she lifts an object. C. Twist at the waist when she moves an object to one side. D. Hold an object away from her body as she lifts it.

Correct Answer is A

Explanation

A. Bend at the knees when picking up an object: This technique helps distribute the weight of the object and reduces strain on the back muscles.

B. Relax her abdominal muscles when she lifts an object: Tensing the abdominal muscles can provide core support, but relaxing them while lifting can increase the risk of injury.

C. Twist at the waist when she moves an object to one side: Twisting at the waist can strain the back muscles and should be avoided.

D. Hold an object away from her body as she lifts it: Holding objects close to the body reduces strain on the back muscles and is a good technique to prevent injury.
