1. What is a physical characteristic of infants whose mothers smoked during pregnancy?
- A. Being large for gestational age
- B. Growth restriction in weight only
- C. Preterm but size appropriate for gestational age
- D. Growth restriction in weight, length, and chest and head circumference
Correct answer: D
Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.
2. The nurse is teaching parents guidelines for feeding their 8-month-old infant with failure to thrive (FTT). Which statement by the parents indicates a need for further teaching?
- A. We will continue to use the 24-kcal/oz formula.
- B. We will be sure to follow the formula preparation instructions.
- C. We will be sure to give our infant at least 8 oz of juice every day.
- D. We will be sure to feed our infant according to the written schedule.
Correct answer: C
Rationale: Providing 8 oz of juice daily is excessive for an 8-month-old infant and can displace other nutrient-rich foods or formulas that are necessary for growth, especially in an infant with FTT.
3. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?
- A. Low hemoglobin
- B. Normal platelet count
- C. High reticulocyte count
- D. Low hematocrit
Correct answer: C
Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.
4. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?
- A. Isotonic dehydration
- B. Hypotonic dehydration
- C. Hypertonic dehydration
- D. Hyperosmotic dehydration
Correct answer: B
Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.
5. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic shock
- B. Cardiogenic shock
- C. Hypovolemic shock
- D. Anaphylactic shock
Correct answer: D
Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.
