The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?
- A. One portion of the intestines invaginates or telescopes into another
- B. Hypertrophy of the circular pylorus muscle
- C. Relaxed cardiac sphincter
- D. Absent ganglion cells in the colon
Correct Answer: B
Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

- B. Sexual promiscuity

- B. Hispanics believe the evil eye enters when a person gets cold
- C. The parent is trying to restore normal balance through appropriate hot remedies

At what stage can infants raise their heads and gain control of their trunks before walking due to which directional pattern of development?
- A. Cephalocaudal
- B. Anterior to posterior
- C. Proximodistal
- D. Normal growth curve charts
Correct Answer: A
Rationale: The correct answer is A: Cephalocaudal. The cephalocaudal pattern of development means that growth and motor control proceed from the head downward through the body. This explains why infants can raise their heads before they can sit and gain control of their trunks before walking. Choices B, C, and D are incorrect. Anterior to posterior refers to development from the front to the back, while proximodistal refers to development from the center of the body outward. Normal growth curve charts are used to track physical growth over time and are not directly related to the directional pattern of development in infants.
