Where do the lesions of atopic dermatitis (eczema) most commonly occur in the infant? (Select all that apply.)
- A. Cheeks
- B. Buttocks
- C. Extensor surfaces of arms and legs
- D. Back
Correct Answer: A
Rationale: In infants with atopic dermatitis (eczema), the lesions most commonly occur on the cheeks (option A) and the extensor surfaces of the arms and legs (option C). The cheeks are a common site of involvement due to increased exposure to irritants and saliva from drooling. The extensor surfaces of the arms and legs are also frequently affected due to scratching and rubbing against clothing. While atopic dermatitis can occur in other areas such as the buttocks, back, and trunk, the cheeks and extensor surfaces are the most common locations in infants.
In the newborn, intramuscular phytonadione (vitamin K) is administered into which muscle?
- A. Deltoid
- B. Dorsogluteal
- C. Vastus medialis
- D. Vastus lateralis
Correct Answer: D
Rationale: In newborns, intramuscular phytonadione (vitamin K) is typically administered into the vastus lateralis muscle. This muscle is located on the front of the thigh and is a commonly used site for IM injections in infants due to its large muscle mass, accessibility, and low risk of hitting major nerves or blood vessels. The vastus lateralis muscle is considered a safe and effective site for administering medications to newborns.
a hospitalized child with nephrosis is receiving high doses of prednisone. which of the following is an appropriate nursing goal related to this?
- A. prevent infection.
- B. stimulate appetite.
- C. detect evidence of edema.
- D. assist in raising osmotic pressure.
Correct Answer: A
Rationale: High doses of prednisone suppress the immune system, putting the hospitalized child at an increased risk for infections. Therefore, an appropriate nursing goal related to this situation would be to prevent infection by implementing measures such as hand hygiene, maintaining a clean environment, and monitoring for signs and symptoms of infection. It is crucial to protect the child from acquiring additional illnesses while undergoing treatment for nephrosis.
An 8-day-old is admitted with vomiting and dehydration. His HR is 170, RR is 44, BP is 85/52, and T is 99°F. The parents ask if these vital signs are normal. Which is the best response?
- A. The BP is elevated.
- B. The temperature is elevated.
- C. The heart rate is elevated; normal for a neonate is 90-160 bpm.
- D. The respiratory rate is elevated.
Correct Answer: C
Rationale: A neonatal heart rate of 170 is above the normal range (90-160 bpm), which is concerning for dehydration.
A neonate, who was delivered by Cesarean section for a breech presentation, is being examined in the neonatal nursery. For which of the following complications should the nurse carefully assess the baby?
- A. Developmental dysplasia of the hips (DDH)
- B. Legg-Calve-Perthes (LCP)
- C. Duchenne muscular dystrophy (DMD)
- D. Slipped capital femoral epiphysis (SCFE)
Correct Answer: A
Rationale: A neonate delivered by Cesarean section for a breech presentation is at higher risk for developmental dysplasia of the hips (DDH). Breech presentation, especially frank breech, increases the chance of hip instability and DDH due to the positioning of the legs in utero. DDH is a condition where the ball and socket joint of the hip does not properly form, leading to potential dislocation of the hip joint. It is important for the nurse to carefully assess the neonate for signs of hip dysplasia, such as limited hip abduction or asymmetry in the thigh folds, to facilitate early detection and intervention for optimal outcomes. Legg-Calve-Perthes (LCP), Duchenne muscular dystrophy (DMD), and slipped capital femoral epiphysis (SCFE) are not specifically related to breech delivery, and therefore, are less likely to be
