Extract:
Question 1 of 5
The nurse is caring for an infant admitted with dehydration, irritability, signs of extreme hunger, and a palpable olive-like mass in the upper right abdominal quadrant. When feeding the infant, the nurse should monitor for which development?
Correct Answer: C
Rationale: Projectile vomiting is characteristic of pyloric stenosis, indicated by the olive-like mass, hunger, and dehydration.
Question 2 of 5
A 34-week gestation multigravida comes to the clinic for her bimonthly appointment. Which assessment finding should the nurse report to the healthcare provider (HCP)?
Correct Answer: B
Rationale: Fundal height of 30 cm is below the expected range (32-36 cm) for 34 weeks gestation, suggesting possible intrauterine growth restriction (IUGR) or oligohydramnios, which requires further evaluation. Mild edema is common, weight gain is normal, and a fetal heart rate of 110 bpm is within the acceptable range.
Question 3 of 5
The mother of a 4-month-old baby girl asks the nurse when should she introduce solid foods to her infant. The mother states, 'My mother says I should put rice cereal in the baby's bottle now.' The nurse should instruct the mother to introduce solid foods when her child exhibits which behavior?
Correct Answer: D
Rationale: Opening the mouth for food, along with head control and sitting support, indicates readiness for solids around 4-6 months.
Question 4 of 5
The nurse is caring for a child with a unilateral long-leg cast applied for the correction of club foot. Which action is most important for the nurse to perform?
Correct Answer: C
Rationale: Monitoring capillary refill ensures adequate circulation in the casted limb, detecting complications like compartment syndrome.
Question 5 of 5
A child who weighs 25 kg receives a prescription for isoniazid 10 mg/kg/day by mouth once a day. The bottle is labeled 'Isoniazid Oral Solution, USP 50 mg per 5 mL.' How many mL should the nurse administer?
Correct Answer: A
Rationale: For a 25 kg child, the dose is 250 mg/day (25 kg × 10 mg/kg). With a concentration of 50 mg/5 mL (10 mg/mL), the volume is 250 mg ÷ 10 mg/mL = 25 mL.
