Extract:
Client at 34 weeks of gestation, at risk for placental abruption
Question 1 of 5
Which of the following is the most common risk factor for a placental abruption?
Correct Answer: C
Rationale: Hypertension is the most common risk factor for placental abruption because it damages placental blood vessels, leading to hemorrhage and detachment. Maternal battering, smoking, and cocaine use are risk factors but are less common than hypertension.
Extract:
Client experiencing preterm labor, scheduled for amniocentesis
Question 2 of 5
The client needs an amniocentesis to determine which of the following findings?
Correct Answer: C
Rationale: In preterm labor, amniocentesis assesses lung maturity (e.g., lecithin/sphingomyelin ratio) to guide delivery planning. Gender, gestation weeks, and anomalies are not primary indications.
Extract:
Client in second trimester, new diagnosis of gestational diabetes
Question 3 of 5
Which statement by the client indicates a need for further teaching?
Correct Answer: C
Rationale: Exercise is crucial for managing gestational diabetes, and reducing it to 3 days a week is insufficient. Clients should aim for moderate exercise most days to control blood glucose.
Extract:
Adult patient, physician orders Magnesium 4 gms loading dose to infuse over 30 minutes at 0500, then infuse a maintenance dose of 1 gram/hr, pharmacy sends 80 Gms in 1000 mL of LR
Question 4 of 5
What would the nurse set the pump for the loading dose at 5 Am? Be sure to enter the number AND the unit of measurement (mL).
Correct Answer: 200 mL/hr
Rationale:
To calculate the IV pump rate for the loading dose, we need to determine how many mL of the solution will deliver 4 grams of magnesium over 30 minutes. The solution is 80 grams in 1000 mL, so the concentration is 80 g / 1000 mL = 0.08 g/mL.
To deliver 4 grams, the volume required is 4 g / 0.08 g/mL = 50 mL. Since this must be infused over 30 minutes (0.5 hours), the rate is 50 mL / 0.5 hr = 100 mL/hr. However, the provided answer is 200 mL/hr, which suggests a possible error in the provided solution. The correct calculation yields 100 mL/hr, but per the document, the answer is listed as 200 mL/hr.
Extract:
