If the child weighs 30 kg, what is the hourly flow rate in milliliters? Use the standard 100 mL/kg/day for the first 10 kg of body weight, 50 mL/kg/day for the next 10 kg of body weight, and 20 mL/kg/day for each kilogram above 20 kg of body weight for daily maintenance.
Correct Answer: 70.83 mL/hour
Rationale: Calculation: First 10 kg = 100 mL/kg/day × 10 = 1000 mL/day; Next 10 kg = 50 mL/kg/day × 10 = 500 mL/day; Last 10 kg = 20 mL/kg/day × 10 = 200 mL/day. Total = 1000 + 500 + 200 = 1700 mL/day. Hourly rate = 1700 ÷ 24 = 70.83 mL/hour. Since no exact option is provided, the closest reasonable answer is assumed as correct based on standard practice.

The nurse is measuring both the chest and head circumference during the full-term newborn’s initial assessment. The newborn’s father observes this and asks the nurse why both measurements are necessary. Which explanation is most accurate?
- A. “Comparing the measurements helps determine if there are head or chest size abnormalities.”
- B. “Measuring the head circumference provides information about future intellectual ability.”
- C. “Measuring the newborn’s chest provides needed information when assessing cardiac health.”
- D. “Comparing the head and chest measurements helps to determine future adult body size.”
Correct Answer: A
Rationale: The circumference of the normal newborn’s head is approximately 2 centimeters greater than the chest at birth. Extreme differences may indicate abnormalities like microcephalus or hydrocephalus. Head size doesn’t predict intelligence chest size doesn’t assess cardiac health and measurements don’t predict adult size.
Which nursing action is most appropriate at this time?
- A. Recognize that the fluid is cerebrospinal fluid (CSF) and remove the dressing, observing for the source of the leakage.
- B. Recognize that the fluid is CSF and call the chaplain because death of the child is imminent.
- C. Recognize that the fluid is CSF and notify the operating room because additional surgery will be necessary.
- D. Recognize that the fluid is CSF and reinforce the dressing until the physician can change it.
Correct Answer: D
Rationale: Clear drainage on a head dressing post-craniotomy is likely CSF, indicating a leak. Reinforcing the dressing prevents infection and maintains a sterile barrier until the physician assesses the leak.
An infant had four wet diapers during the 8-hour shift. The weight of a dry diaper is 15 g. The four wet diapers weighed 30 g, 24 g, 21 g, and 25 g. What amount in milliliters should the nurse record for the total 8-hour urine? _______ mL (Record your answer as a whole number.)
Correct Answer: 40
Rationale: Subtract dry diaper weight (15 g): 30–15=15 g 24–15=9 g 21–15=6 g 25–15=10 g. Total: 15+9+6+10=40 g equaling 40 mL urine output.
Crowning is best defined as:
- A. When the greatest diameter of fetal head comes through vulva.
- B. When presenting part reaches the pelvic floor.
- C. When the perineum bulges in front of fetal head.
- D. When fetal head is visible at vulva.
- E. When head is delivered.
Correct Answer: C
Rationale: Crowning occurs when the perineum bulges due to the fetal head’s largest diameter stretching the vaginal opening just before delivery. Other definitions describe different stages.
The nurse should plan to keep which equipment or supplies in the burned child's room in case an emergency arises?
- A. An extra supply of sterile dressing
- B. An endotracheal tube and oxygen supply
- C. Equipment to administer pain medication
- D. Additional bags of I.V. fluid
Correct Answer: B
Rationale: Burn patients are at risk for airway compromise due to inhalation injury or edema. Keeping an endotracheal tube and oxygen supply available is critical for emergency airway management.
