Question 1 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.
Question 2 of 5
The nurse is caring for a primigravida client who delivered vaginally 48-hours ago. The client's laboratory results are: hemoglobin 12.5 g/dL (125 g/L), hematocrit 34% (0.34 volume fraction), hepatitis B surface antigen negative, rubella non-immune, group B Streptococcus positive. Which prescription should the nurse prepare to administer?
Correct Answer: B
Rationale: The client's rubella non-immune status requires postpartum vaccination to prevent future congenital defects. Normal hemoglobin/hematocrit, negative hepatitis B, and post-delivery GBS status do not warrant other interventions.
Question 3 of 5
A preschool-aged child who is experiencing respiratory distress is brought to the emergency department by the parents. The child is anxious, has a temperature of 102.8° F (39.3° C), and is drooling from the mouth while leaning forward when sitting. Which action should the nurse implement next?
Correct Answer: C
Rationale: Symptoms suggest epiglottitis, requiring immediate airway management. Intubation/tracheotomy trays are critical to address potential airway obstruction.
Question 4 of 5
A multiparous client with active herpes lesions is admitted to the unit with spontaneous rupture of membranes. Which action should the nurse take?
