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 C

Explanation

A. "There is no way to predict how long it will last for each individual client, so you'll just have to wait and see." While there is some individual variation, urinary frequency generally follows a predictable pattern during pregnancy, subsiding after the first trimester and returning near the end.

B. "No, in most cases it only lasts until about the 12th week, but it will continue if you have poor bladder tone." Bladder tone does not typically affect the course of urinary frequency during pregnancy. This response provides misleading information and lacks support.

C. "No, it should only last until about your 12th week, but it will return near the end of the pregnancy." Urinary frequency is common in the first trimester due to hormonal changes and increased blood flow to the pelvic area. It typically subsides after the 12th week of pregnancy when the uterus rises out of the pelvis. However, it often returns in the third trimester when the growing uterus presses on the bladder again.

D. "Yes, it will, but if you decrease your fluid intake, especially at bedtime, it won't be so bothersome." Although reducing fluid intake at bedtime may help with nighttime frequency, advising the client to reduce fluid intake overall is not recommended, as adequate hydration is essential during pregnancy.

A. Prepare the client for admission to the hospital B. Document the findings as expected in the client records. C. Repeat the contraction stress test in 24 hr. D. Check the client's cervix for dilation.

Correct Answer is A

Explanation

A. Prepare the client for admission to the hospital. A positive contraction stress test indicates that there are late decelerations of the fetal heart rate with contractions, suggesting that the fetus may not tolerate labor well. Hospital admission is often necessary for further monitoring and possible intervention.

B. Document the findings as expected in the client records. A positive contraction stress test is an abnormal finding, not an expected one. It indicates potential fetal distress and requires immediate attention.

C. Repeat the contraction stress test in 24 hr. If the test is positive, further immediate action is needed, such as close monitoring or possible delivery, rather than waiting 24 hours to repeat the test.

D. Check the client's cervix for dilation. While cervical dilation may be assessed if the client is in labor, this action does not address the immediate concern of fetal distress indicated by a positive contraction stress test.
