Extract:
Question 1 of 5
A patient in active labor is prescribed oxytocin 12 milliunits/min intravenously (IV). The IV bag contains 5 units of oxytocin in 500 mL of lactated Ringer's solution. How many mL/hour should the nurse set the infusion pump to? (Enter numerical value only)
Correct Answer: 0.72
Rationale: The concentration is 5 units/500 mL = 0.01 units/mL. Convert 12 milliunits/min to 0.72 units/hour (12/1000 * 60). Infusion rate is 0.72/0.01 = 72 mL/hour.
Question 2 of 5
The MMR vaccine (measles, mumps, and rubella) is given subcutaneously at a dose of 0.5 mL if the patient is not immune to rubella. How should the risk of Venous Thromboembolism (VTE) and Postpartum Hemorrhage (PPH) be evaluated?
Correct Answer: B
Rationale: MMR vaccination does not directly increase VTE or PPH risk. Evaluating based on overall health and pregnancy factors, with prophylaxis for moderate to high risk, is appropriate per policy.
Question 3 of 5
A female adolescent with pelvic inflammatory disease (PID) is admitted to the hospital after 14 days of taking levofloxacin 500 mg by mouth (PO) once daily and metronidazole 500 mg PO twice daily. She asks the nurse, 'Why do I have to be in the hospital? Why can't I get my treatment at home?' What purpose should the nurse provide that supports an effective outcome?
Correct Answer: B
Rationale: Hospitalization ensures effective treatment through supervised parenteral antibiotics for severe PID, improving outcomes. Contact precautions, Jarisch-Herxheimer reaction, and cultures are not primary reasons.
Question 4 of 5
The nurse finds that an infant admitted for surgical repair of an inguinal hernia voids a urinary stream from the ventral surface of the penis. What action should the nurse take?
Correct Answer: C
Rationale: Voiding from the ventral penis suggests hypospadias, a congenital condition. Documenting this finding ensures it is reported and addressed appropriately.
Question 5 of 5
A client's maternal serum alpha-fetoprotein level is elevated at 17 weeks. What condition should the nurse identify as the likely cause of this increase?
Correct Answer: D
Rationale: Elevated maternal serum alpha-fetoprotein at 17 weeks is most commonly associated with neural tube defects. Multiple gestation may also increase levels but is less likely, while Down syndrome and fetal hypoxia typically do not cause this elevation.
