Extract:
Client in labor, oxytocin (Pitocin) infusing at 15 mu/minute, has 20 units of Pitocin in 1000 mL of Normal Saline IV solution
Question 1 of 5
If this client is receiving 15 mu/min, then how many mL/hr would her IV infusion pump be set at? Be sure to enter the number AND the unit of measurement (mL).
Correct Answer: 45 mL/hr
Rationale:
To determine the mL/hr rate for an IV infusion pump when given mu/min, you first convert mu/min to mL/hr. Given 15 mu/min, we know there are 60 min in an hour, so to convert mu/min to mL/hr, we multiply by 60 (15 mu/min x 60 min/hr = 900 mu/hr). Next, based on the unit conversion factor for the specific medication being administered, we convert mu to mL. If the conversion factor is 1 mu = 1 mL, then the mL/hr rate would be 900 mL/hr. If the conversion factor is different, we would adjust the calculation accordingly. Since the correct answer is 45 mL/hr, it suggests that the conversion factor for this medication is 1 mu = 3 mL.
Therefore, 900 mu/hr would be equivalent to 45 mL/hr (900 mu/hr รท 3 mL/mu = 45 mL/hr). The other choices are incorrect as they do not follow
Extract:
Client regarding how to reduce the risk of giving birth to a newborn who has a neural tube defect
Question 2 of 5
Which of the following instructions by the nurse is appropriate?
Correct Answer: B
Rationale: The correct answer is B: Eat foods fortified with folic acid. This instruction is appropriate because folic acid is crucial during pregnancy for preventing birth defects. Iron intake (
A) is important too, but not the most appropriate here. Aspirin avoidance (
C) is relevant due to its potential risks. Limiting alcohol (
D) is important, but not as critical as folic acid. The other choices are not applicable or less crucial in this context.
Extract:
Client at 34 weeks of gestation, at risk for placental abruption
Question 3 of 5
Which of the following is the most common risk factor for a placental abruption?
Correct Answer: C
Rationale: The correct answer is C: Maternal hypertension. Placental abruption is the premature separation of the placenta from the uterus before delivery. Hypertension can lead to reduced blood flow to the placenta, increasing the risk of abruption. Maternal battering (
A) can cause trauma but is not the most common risk factor. Maternal cigarette smoking (
B) and cocaine use (
D) can also increase the risk but are not as prevalent as hypertension. Other factors may include advanced maternal age, multiple pregnancies, and previous history of placental abruption.
Extract:
Client at 38 weeks of gestation, heavy red vaginal bleeding without contractions, no distress, can feel baby moving
Question 4 of 5
The client should undergo an ultrasound to determine which of the following findings?
Correct Answer: C
Rationale: The correct answer is C: Location of the placenta. An ultrasound can determine the exact position of the placenta in relation to the cervix, which is crucial for assessing the risk of placenta previa or other complications during pregnancy. This information guides healthcare providers in making appropriate decisions regarding delivery methods.
Other choices are incorrect because:
A: Fetal lung maturity is usually assessed through other methods like amniocentesis.
B: Frequency and duration of contractions are usually monitored through external monitoring devices.
D: Rh incompatibility is typically detected through blood tests, not ultrasound.
Extract:
Client in second trimester, new diagnosis of gestational diabetes
Question 5 of 5
Which of the following statements by the client indicates a need for further teaching?
Correct Answer: C
Rationale: The correct answer is C because reducing the exercise schedule to 3 days a week goes against the goal of managing diabetes, which typically requires consistent physical activity. Regular exercise helps control blood sugar levels, improves insulin sensitivity, and promotes overall health.
Choices A, B, and D demonstrate an understanding of diabetes management and medication adherence, indicating no need for further teaching in those areas.
