Baby M is 5 months old. You notice that she now has the ability to grasp objects between her fingers and opposing thumb. This is known as:
- A. Parachute reflex
- B. Grasp reflex
- C. Pincer grasp
- D. Prehension
Correct Answer: C
Rationale: The correct answer is C: Pincer grasp. The pincer grasp is the ability to hold objects between the thumb and another finger, typically developed around 9-12 months. At 5 months, it is early for a pincer grasp to fully develop, but the beginning of this skill can be seen as early as 5 months. Choices A and B are incorrect as the parachute reflex is a protective response to falling and the grasp reflex is an automatic response to touch. Choice D, prehension, is a general term for the act of grasping or holding objects, but it does not specifically refer to holding objects between the thumb and fingers like the pincer grasp does.

The parents of a child with sickle cell anemia ask why their child did not have a sickle cell crisis until he was approximately 6 months old. How should the nurse respond?
- A. Your child probably had a crisis, and you were unaware of the symptoms.
- B. Are you sure your child has sickle cell anemia and not sickle cell trait?
- C. Affected children can be asymptomatic in early infancy because of high levels of fetal hemoglobin that inhibit sickling.
- D. Have you asked your doctor about this yet?
Correct Answer: C
Rationale: The correct answer is C. Fetal hemoglobin (HbF) is present in high levels during early infancy, inhibiting sickling unlike adult hemoglobin (HbS). As the levels of HbF decrease and HbS increases, the risk of sickling and crises becomes more pronounced, typically after 6 months of age. Choice A is incorrect because it assumes the crisis went unnoticed, which is not supported by medical knowledge. Choice B is incorrect as it questions the child's diagnosis rather than explaining the phenomenon of delayed crises. Choice D is incorrect as it does not provide the parents with the necessary information regarding their query.
Why is knowledge of developmental theories useful for the nurse?
- A. Allows the nurse to know exactly what to do when caring for pediatric patients
- B. Is predictable and aids in controlling the child's development
- C. Is a set of facts that each child follows in a prescribed method
- D. Provides a framework to guide the nurse in caring for the patient
Correct Answer: D
Rationale: The correct answer is D. Understanding developmental theories helps nurses anticipate and plan appropriate care based on the child's developmental stage. Choice A is incorrect because developmental theories provide a framework but do not dictate exact actions. Choice B is incorrect as developmental processes are not entirely predictable and are not meant to control a child's development. Choice C is incorrect as developmental theories are not a strict set of facts that all children follow in a prescribed manner, but rather guidelines for understanding and supporting a child's growth and development.
