A nurse is providing prenatal care to a pregnant client. At which time would the nurse expect to screen the client for group B streptococcus infection?

28 weeks' gestation

32 weeks' gestation

16 weeks' gestation

36 weeks' gestation

Answer and Explanation

The Correct Answer is D

Choice A: 28 weeks' gestation is too early to screen for group B streptococcus infection. Group B streptococcus (GBS) is a type of bacteria that can cause serious infections in newborns if transmitted from the mother during labor and delivery. The optimal time to screen for GBS is between 35 and 37 weeks' gestation.

Choice B: 32 weeks' gestation is also too early to screen for GBS infection. Screening at this time may not reflect the true colonization status of the mother at the time of delivery, as GBS can be transient or intermittent.

Choice C: 16 weeks' gestation is much too early to screen for GBS infection. Screening at this time has no clinical value, as GBS colonization can change throughout pregnancy.

Choice D: 36 weeks' gestation is the appropriate time to screen for GBS infection. Screening at this time can identify mothers who are colonized with GBS and who need intrapartum antibiotic prophylaxis to prevent neonatal sepsis, pneumonia, and meningitis.

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because ferrous sulfate is an iron supplement that is used to treat or prevent iron-deficiency anemia. It has no effect on magnesium sulfate, which is a medication that lowers blood pressure and prevents seizures in severe preeclampsia.

Choice B Reason: This is incorrect because potassium chloride is an electrolyte supplement that is used to treat or prevent low levels of potassium in the blood. It has no effect on magnesium sulfate, which can cause hypermagnesemia, or high levels of magnesium in the blood.

Choice C Reason: This is incorrect because calcium carbonate is an antacid that is used to treat or prevent heartburn, indigestion, or calcium deficiency. It has no effect on magnesium sulfate, which can cause hypocalcemia, or low levels of calcium in the blood.

Choice D Reason: This is correct because calcium gluconate is an antidote that is used to treat magnesium toxicity, which can occur when magnesium sulfate is given in high doses or for prolonged periods. Calcium gluconate reverses the effects of magnesium sulfate on the neuromuscular and cardiovascular systems, such as muscle weakness, respiratory depression, cardiac arrhythmias, or cardiac arrest.

Correct Answer is ["2"]

Explanation

Step 1: Determine the total daily dose of quetiapine.

The provider prescribes 50 mg every 12 hours.
Total daily dose = 50 mg × 2 = 100 mg.

Step 2: Calculate the total dose for 3 days.

Total dose for 3 days = 100 mg × 3 = 300 mg.

Step 3: Determine the dose per administration.

The total daily dose is divided into two doses (every 12 hours).
Dose per administration = 100 mg ÷ 2 = 50 mg.

Step 4: Calculate the number of tablets needed per dose.

Each tablet is 25 mg.
Number of tablets per dose = 50 mg ÷ 25 mg = 2 tablets.

Step 5: Confirm the number of tablets to be administered per dose on day 3.

The dose per administration remains the same each day.
Therefore, the nurse should administer 2 tablets per dose on day 3.

So, the nurse should administer 2 tablets per dose on day 3.
