A nurse is assisting with the care of a client who is at 34 weeks of gestation and received a dose of nifedipine 2 hr ago. For which of the following therapeutic effects should the nurse monitor?
An increase in platelet count
A decrease in blood pressure
A decrease in FHR
An increase in urinary output
The Correct Answer is B

Correct Answer is A
Explanation
A. Increased uterine tone: Methylergonovine is a medication used to prevent or treat postpartum hemorrhage. It works by causing uterine contractions, which helps to control bleeding. An indication that the medication is effective would be an increase in uterine
tone, as this signifies that the uterus is contracting appropriately.
B. Blood pressure 120/74 mm Hg: While a blood pressure of 120/74 mm Hg is within the normal range, it does not specifically indicate the effectiveness of methylergonovine.
Blood pressure is an important parameter to monitor, but it alone does not determine the effectiveness of the medication.
C. Decreased perineal edema: Decreased perineal edema may be a positive sign for the client's overall recovery, but it is not a direct indicator of methylergonovine's
effectiveness. Perineal edema is not a primary concern addressed by this medication.
D. Urinary output 100 mL/hr: Urinary output of 100 mL/hr is an important parameter to monitor for renal function. However, it does not specifically indicate the effectiveness of methylergonovine in preventing or treating postpartum hemorrhage. Urinary output is crucial for assessing kidney function and fluid balance but is not directly related to the action of this medication.
Correct Answer is A
Explanation
A. Among the options listed, the intrauterine device (IUD) has the lowest failure rate. IUDs are highly effective at preventing pregnancy with a failure rate of less than 1%.
B. Oral contraceptives have a higher failure rate compared to IUDs.
C. The contraceptive sponge has a higher failure rate compared to IUDs.
D. The diaphragm has a higher failure rate compared to IUDs.
