A nurse is preparing to administer levothyroxine 50 mcg to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Desired dose = 50 mcg
Available strength = 0.025 mg/tablet
- Convert desired dose to milligrams (mg):
1 mg = 1000 mcg
50 mcg / 1000 mcg/mg = 0.05 mg
- Calculate the number of tablets:
Number of tablets = Desired dose (mg) / Available strength (mg/tablet)
= 0.05 mg / 0.025 mg/tablet
= 2 tablets

Correct Answer is B
Explanation
A. Initiate an oxytocin IV infusion. Oxytocin may be used to augment labor, but it should not be started immediately without first assessing maternal and fetal well-being. Continuous monitoring is necessary before initiating any uterotonic agent.
B. Apply a fetal heart rate monitor. After rupture of membranes, assessing the fetal heart rate is critical to detect signs of umbilical cord prolapse or fetal distress. Continuous electronic fetal monitoring helps evaluate the baby's response to labor.
C. Initiate fundal massage. Fundal massage is performed after delivery of the placenta to help contract the uterus and reduce postpartum bleeding. It is not appropriate during active labor.
D. Insert an indwelling urinary catheter. A catheter may be placed if necessary during labor, especially before epidural anesthesia, but it is not the immediate priority following membrane rupture. Fetal monitoring takes precedence.
Correct Answer is D
Explanation
A. Urinary output 120 mL/4 hr. This is on the lower end of normal but not critical. It should be monitored, especially in clients on opioids, but does not require immediate reporting ahead of more life-threatening findings.
B. Pupil diameter 6 mm. Dilated pupils may suggest other issues such as anxiety, medication effects, or pain, but are not a common concern with morphine, which usually causes miosis (pupil constriction). Still, this is not the most urgent concern.
C. Bowel movement 5 days ago. Constipation is a common side effect of opioids, including morphine, and should be addressed with stool softeners or laxatives. However, it is not an emergency.
D. Blood pressure 80/40 mm Hg. This indicates hypotension, a potentially life-threatening side effect of IV morphine, especially if it results in decreased perfusion or shock. It requires immediate intervention and provider notification.
