A nurse is caring for a client who has placenta previa. Which of the following interventions should the nurse implement for this client? (Select all that apply.)

Choice A rationale:

Leaving the diaphragm in place for 4 hours following intercourse is incorrect. The diaphragm should be left in place for at least 6 hours after intercourse to ensure effectiveness in preventing pregnancy.

Choice B rationale:

Removing the diaphragm by catching the rim below the dome with the forefinger is incorrect. The diaphragm should be removed by hooking the finger behind the rim to avoid damaging the dome and ensure proper removal.

Choice C rationale:

Placing a thin layer of mineral oil on the diaphragm once per week is incorrect. Mineral oil can weaken latex diaphragms, reducing their effectiveness. Water-based lubricants are recommended for use with diaphragms.

Choice D rationale:

Placing 2 teaspoons of spermicide on the inside of the diaphragm before insertion is the correct technique. Spermicide helps to immobilize and kill sperm, enhancing the contraceptive effect of the diaphragm.

Choice A rationale:

While there is a risk of infection with any internal examination, it is not the primary reason for avoiding internal examinations in a client with placenta previa. The main concern is avoiding trauma to the placenta, which could result in significant bleeding.

Choice B rationale:

Although internal examinations may potentially stimulate uterine contractions, leading to preterm labor in some cases, this is not the primary reason for avoiding such examinations in clients with placenta previa. The primary concern remains the risk of bleeding due to placental disruption.

Choice C rationale:

The correct explanation for the nurse to provide is that an internal examination could result in profound bleeding. Placenta previa occurs when the placenta partially or completely covers the cervix, and any manipulation of the cervix or uterus through an internal examination could disrupt the placenta and cause severe bleeding, endangering both the mother and the baby.

Choice D rationale:

While there is a risk of rupturing the membranes during an internal examination, this is not the primary reason for avoiding such examinations in clients with placenta previa. The primary concern remains the risk of bleeding due to placental disruption.
