A client's last menstrual period was April 11. Using Naegele's rule, her estimated date of birth (EDB) would be:

February 24

January 18

January 25

February 18

Answer and Explanation

The Correct Answer is D

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 18.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because difficulty in arousing is a sign of magnesium toxicity, which is a serious complication of magnesium sulfate therapy. Magnesium toxicity can cause central nervous system depression, muscle weakness, and cardiac arrest. The nurse should monitor the client's level of consciousness and stop the infusion if the client becomes lethargic or unresponsive.

Choice B Reason: This is correct because deep tendon reflexes 2+ indicate a normal and expected response to magnesium sulfate therapy. Magnesium sulfate is a muscle relaxant that can reduce the risk of seizures in gestational hypertension. The nurse should assess the client's deep tendon reflexes regularly and maintain them at 2+ or slightly diminished.

Choice C Reason: This is incorrect because urinary output of 30 mL per hour is below the normal range of 40 to 80 mL per hour and may indicate renal impairment or dehydration. Magnesium sulfate can cause renal toxicity or fluid retention, which can affect the urinary output. The nurse should monitor the client's urinary output and fluid balance and report any abnormalities to the doctor.

Choice D Reason: This is incorrect because respiratory rate of 10 breaths/minute is below the normal range of 12 to 20 breaths/minute and may indicate respiratory depression. Magnesium sulfate can cause respiratory depression or failure, which can be life-threatening. The nurse should monitor the client's respiratory rate and oxygen saturation and administer oxygen or antidote if needed.

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.
