By adding 7 days to the first day of the client's last menstrual cycle and then subtracting 3 months and 1 year

Answer and Explanation

The Correct Answer is A

A. By subtracting 3 months from the first day of the client's last menstrual cycle and then adding 7 days and 1 year: This is Naegele's rule for estimating the due date: subtract 3 months from the first day of the last menstrual period (LMP), add 7 days, and then add 1 year.

B. By adding 3 months to the first day of the client's last menstrual cycle and then subtracting 7 days and 1 year: This reverses the correct order. You subtract 3 months, not add.

C. By subtracting 7 days from the first day of the client's last menstrual cycle and then adding 3 months and 1 year: This calculation incorrectly subtracts days instead of adding days.

D. By adding 7 days to the first day of the client's last menstrual cycle and then subtracting 3 months and 1 year: The rule adds days and subtracts months, but adding a year here is not correct. You add 1 year at the end.

Correct Answer is B

Explanation

A. Keep the client on bed rest. While bed rest may be ordered in some cases, it is not the primary intervention for incomplete abortion. Active management, such as monitoring for complications or surgical interventions, is often needed.

B. Determine the amount and type of vaginal bleeding. Assessing the type and amount of vaginal bleeding is crucial in monitoring the progress of an incomplete abortion and determining the need for further interventions, such as dilation and curettage (D&C) or medication.

C. Administer oxygen via facemask. Oxygen administration is not routinely indicated for incomplete abortion unless there is severe blood loss or signs of shock, which is not mentioned in this scenario.

D. Instruct the client in appropriate birth control methods. While birth control instruction is important, it is not a priority at this moment when the focus should be on managing the incomplete abortion.

A. A 15-year old client who has acne B. A client who has a menstrual cycle every 14 days C. A client who has a hematocrit of 39% (expected range 37% -47%) D. A client who has a blood pressure of 146/92 mm Hg

Correct Answer is D

Explanation

A. A 15-year-old client who has acne: Oral contraceptives are often used to treat acne in adolescents and are not contraindicated in this case.

B. A client who has a menstrual cycle every 14 days: Irregular or frequent menstrual cycles are not a contraindication to oral contraceptive use. In fact, oral contraceptives are sometimes used to regulate menstrual cycles.

C. A client who has a hematocrit of 39% (expected range 37%-47%): A hematocrit of 39% is within the normal range and does not pose a contraindication to oral contraceptive use.

D. A client who has a blood pressure of 146/92 mm Hg: Oral contraceptives can increase blood pressure and are contraindicated in clients with uncontrolled hypertension (above 140/90 mm Hg) due to the risk of thromboembolic events and cardiovascular complications.
