1. Why is a prolapsed umbilical cord dangerous?

A. The cord may be wrapped around the baby's neck, causing strangulation.
B. The cord might pull the placenta from the uterine wall during delivery.
C. The baby's head may compress the cord, cutting off its supply of oxygen.
D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

2. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?

A. 45%
B. 63%
C. 72%
D. 54%

Correct answer: A

Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.

3. When assessing a 6-year-old boy with pain in the right lower quadrant of his abdomen, which action should be performed first?

A. Avoiding palpation of the abdomen.
B. Palpating the right lower quadrant first.
C. Auscultating bowel sounds for 2 minutes.
D. Palpating the left upper quadrant first.

Correct answer: D

Rationale: Palpating the left upper quadrant first is the correct approach when assessing abdominal pain in a child. This method helps to minimize causing additional discomfort to the child and allows for a more accurate assessment of their reaction to palpation. By starting on the left upper quadrant, you can gauge the child's pain response before moving to the area of complaint, which may be more sensitive. This approach is essential for a thorough and less distressing abdominal assessment in pediatric patients.

4. The healthcare provider is assessing a postpartum client who is 1 day post-delivery. Which finding would require immediate intervention?

A. Lochia rubra with a few small clots
B. Fundus firm and midline
C. Temperature of 100.4Â°F (38Â°C)
D. Saturated perineal pad in 15 minutes

Correct answer: D

Rationale: A saturated perineal pad in 15 minutes indicates excessive bleeding, known as postpartum hemorrhage, which is a critical condition requiring immediate intervention to prevent further complications like hypovolemic shock. Monitoring and managing postpartum bleeding are crucial in the early postpartum period to ensure the client's safety and well-being. The other options are normal postpartum findings: lochia rubra with a few small clots is expected in the early postpartum period, a firm and midline fundus indicates proper uterine contraction, and a temperature of 100.4Â°F (38Â°C) is within the normal range for the postpartum period.

5. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse'. Hormones communicate this effect by their unique chemical structures recognized by specific receptors on their target cells, by their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

A. Producing new offspring
B. Promoting growth and beauty
C. Maintaining body temperature
D. Fighting infections

Correct answer: A

Rationale: The function of producing new offspring is not attributed to hormones. Hormones primarily regulate various physiological processes in the body such as growth, metabolism, reproduction, and immune response, but they do not directly play a role in producing offspring.
