Nursing Elites

1. The LPN is assessing for fontanels on the head of a 6-month-old. Which fontanel is expected to still be present?

• A. Posterior
• B. Anterior
• C. Sphenoid
• D. Lambdoid

Correct answer: B

Rationale: The correct answer is B: Anterior. The anterior fontanel usually remains open until about 12-18 months of age, while the posterior fontanel closes by 2-3 months. Choices A, C, and D are incorrect as the posterior fontanel closes by 2-3 months of age, and the sphenoid and lambdoid fontanels are not typically assessed in routine infant head examinations.

2. Which pediatric condition is characterized by a "string sign" on an upper GI series?

• A. Intussusception
• B. Hypertrophic pyloric stenosis
• C. Hirschsprung disease
• D. Meckel diverticulum

Correct answer: B

Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.

3. The parents of a 2-month-old boy are concerned about spoiling their son by picking him up when he cries. What is the nurse's best response?

• A. Allow him to cry for no longer than 15 minutes and then pick him up
• B. Babies need comforting and cuddling. Meeting these needs will not spoil him
• C. Babies this young cry when they are hungry. Try feeding him when he cries
• D. If he isn’t soiled or wet, leave him, and he'll cry himself to sleep

Correct answer: B

Rationale: Comforting and cuddling a 2-month-old baby when they cry helps build trust and security. At this age, responding to cries does not lead to spoiling, but rather supports healthy emotional development.

4. The nurse is teaching a client to prevent future urinary tract infections (UTIs). What factor is most important to emphasize as the potential cause?

• A. Poor hygiene
• B. Constipation
• C. Urinary stasis
• D. Congenital anomalies

Correct answer: C

Rationale: Urinary stasis is the most important factor in the development of UTIs because it provides an environment for bacterial growth. While poor hygiene and congenital anomalies are contributing factors, preventing urinary stasis is key in UTI prevention.

5. Which of the following is the best indicator of a child's nutritional status?

• A. Weight
• B. Height
• C. Head circumference
• D. Mid-upper arm circumference

Correct answer: D

Rationale: Mid-upper arm circumference is a good indicator of muscle mass and fat stores, reflecting a child's nutritional status. It is particularly useful in assessing malnutrition, as it is less affected by fluid retention or dehydration compared to other anthropometric measurements. Weight can fluctuate due to factors like hydration status, making it less reliable as a sole indicator of nutritional status. Height reflects growth but may not directly indicate current nutritional status. Head circumference is more related to brain growth and development rather than overall nutritional status.
