12-month-old boy weighed 8 lb 2 oz at birth. Understanding developmental milestones, what should the nurse caring for the child expect the current weight to be?
24 lb 6 oz
20 lb 5oz
32 lb 8 0z
16 lb 4 oz
The Correct Answer is A
To predict the expected weight of the 12-month-old boy, we can use the general guideline that a child's weight should triple from birth to 12 months.
Given that the boy weighed 8 lb 2 oz at birth, we can calculate the expected weight at 12 months by tripling this weight.
8 lb 2 oz = 8.125 lb
Tripling this weight:
8.125 lb * 3 = 24.375 lb
Now, we convert this weight back to pounds and ounces:
0.375 lb * 16 = 6 oz
So, the expected weight of the 12-month-old boy should be approximately 24 lb 6 oz.

Correct Answer is A
Explanation
A. Projectile vomiting
Projectile vomiting is a classic symptom of pyloric stenosis in infants. It typically occurs within 30 minutes of feeding and is forceful, often projecting several feet away from the infant. This occurs due to the obstruction at the pyloric sphincter, leading to the stomach forcefully emptying its contents.
B. Metabolic acidosis
Metabolic acidosis is not a typical finding associated with pyloric stenosis. Pyloric stenosis leads to vomiting, which can result in dehydration and electrolyte imbalances, but it typically does not cause metabolic acidosis directly.
C. Effortless regurgitation
Effortless regurgitation is not a characteristic finding of pyloric stenosis. In pyloric stenosis, vomiting is forceful and projectile, rather than a passive regurgitation of stomach contents.
D. Distended abdomen
A distended abdomen can be a finding in pyloric stenosis. The obstruction at the pyloric sphincter can lead to gastric retention, causing the stomach to become distended over time. However, it's important to note that not all infants with pyloric stenosis will present with a visibly distended abdomen.
Correct Answer is D
Explanation
A. Patches of baldness: Patches of baldness on the scalp could be indicative of conditions like alopecia areata, a disorder characterized by hair loss in patches. However, it is not a typical manifestation of pediculosis capitis, which primarily presents with scalp itchiness due to lice bites rather than hair loss.
B. Blisters on the scalp: Blisters on the scalp may suggest other conditions such as herpes simplex infection or contact dermatitis. While scratching from head lice infestation could lead to skin irritation, blisters are not a common presentation of pediculosis capitis.
C. Dry patches on the scalp: Dry patches on the scalp might be caused by conditions like seborrheic dermatitis or eczema. While scalp dryness can occur with pediculosis capitis due to irritation from scratching, it is not a specific symptom associated with head lice infestation.
D. Reports of scalp itchiness: Scalp itchiness is a hallmark symptom of pediculosis capitis. It occurs as a result of lice bites and the body's inflammatory response to their saliva. It is the most characteristic and common manifestation of head lice infestation and often prompts further examination for the presence of lice or their eggs (nits).
