1. Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?
- A. Increased blood pressure
- B. A sunken fontanel
- C. Decreased pulse rate
- D. Low urine specific gravity
Correct answer: B
Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.
2. Which reflex is expected to disappear by 4 months of age?
- A. Rooting reflex
- B. Moro reflex
- C. Babinski reflex
- D. Palmar grasp
Correct answer: B
Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.
3. What is the first sign of puberty in girls?
- A. Acne
- B. Hair growth in the pubic area and underarms
- C. Thelarche
- D. Menarche
Correct answer: C
Rationale: The correct answer is C, Thelarche. Thelarche refers to the onset of breast development, which is typically the first sign of puberty in girls. This occurs before menarche (the first menstrual period). Choices A and B, acne and hair growth in the pubic area and underarms, are not the first signs of puberty in girls. While acne can be a common occurrence during puberty, it usually appears after other physical changes. Hair growth in the pubic area and underarms also occurs later in the puberty process.
4. The nurse determines that a child's intravenous infusion has infiltrated. The infused solution is a vesicant. What is the most appropriate nursing action?
- A. Stop the infusion and apply ice.
- B. End the infusion and notify the practitioner.
- C. Slow the infusion rate and notify the practitioner.
- D. Discontinue the infusion and apply warm compresses.
Correct answer: B
Rationale: If a vesicant solution infiltrates, stopping the infusion immediately and notifying the practitioner is critical to prevent tissue damage. Cold or warm compresses should only be applied following specific medical advice based on the vesicant involved.
5. What is the best indicator of fluid balance in a pediatric patient?
- A. Blood pressure
- B. Heart rate
- C. Weight
- D. Urine output
Correct answer: C
Rationale: Weight is the most accurate indicator of fluid balance in pediatric patients. Changes in weight reflect shifts in body fluid levels more directly compared to other parameters. Blood pressure and heart rate may be affected by various factors other than fluid balance. While urine output is important in assessing renal function, it may not provide a comprehensive picture of overall fluid balance in pediatric patients.
