A pregnant woman experiencing nausea and vomiting should:.

To calculate the estimated date of confinement (EDC) using Nagele's rule, follow these steps:

1. Take the first day of the last menstrual period (LMP).

2. Add 7 days to that date.

3. Count back 3 months.

4. Add 1 year to the resulting date, and that will be the EDC.

In this case, the client's LMP started on December 1.

1. December 1

2. December 8 (adding 7 days)

3. September 8 (counting back 3 months)

4. Add 1 year: September 8 of the following year

So, the most accurate EDC for the client using Nagele's rule would be September 8 of the following year.

Choice A rationale:

Pouring water from a squeeze bottle over the woman's perineum is a common technique used to ease perineal discomfort after childbirth, but it does not address the issue of a full bladder preventing the uterus from contracting normally.

Choice B rationale:

Placing oil of peppermint in a bedpan under the woman is a technique used to encourage relaxation and help the woman empty her bladder spontaneously. The smell of peppermint can stimulate the relaxation of pelvic muscles, making it easier for the woman to urinate. This method is often effective in encouraging postpartum women to empty their bladders, which is important for uterine contraction and preventing postpartum hemorrhage.

Choice C rationale:

Asking the physician to prescribe analgesics may help manage pain but does not directly address the issue of a full bladder preventing normal uterine contractions.

Choice D rationale:

Inserting a sterile catheter is a medical intervention that might be necessary if the woman cannot empty her bladder spontaneously. However, it is typically considered after other non-invasive methods, such as the use of peppermint oil, have been attempted and failed. Inserting a catheter should be done with caution to avoid introducing infection and discomfort to the woman.
