A nurse in a provider's office is planning care for a client who has a new diagnosis of polycystic ovarian syndrome. The nurse should plan to monitor which of the followinglaboratory values?

Rationale:

A. Metronidazole: Metronidazole is an antibiotic and does not have significant interactions with sildenafil.

B. Phenytoin: Phenytoin is an anticonvulsant medication and does not have significant interactions with sildenafil.

C. Prednisone: Prednisone is a corticosteroid and does not have significant interactions with sildenafil.

D. Isosorbide: Isosorbide is a nitrate medication used to treat angin

A. Combining sildenafil with nitrate medications can lead to severe hypotension and is contraindicated. Sildenafil potentiates the vasodilatory effects of nitrates, which can result in a dangerous drop in blood pressure.

- A. Administer oxygen via face mask.
- Administering oxygen can be beneficial as it increases maternal oxygenation, which can improve fetal oxygenation. However, it is not the first-line action for late decelerations.Late decelerations are a sign of uteroplacental insufficiency, and while oxygen helps, repositioning the mother is more critical to address the root cause. Oxygen administration is a supportive measure but does not directly address the potential compression of the umbilical cord or placental perfusion issues.

- B. Position the client on her side.
Positioning the client on her side, specifically the left side, can improve uteroplacental circulation, addressing the cause of late decelerations.This position helps to relieve pressure on the inferior vena cava, enhancing blood flow to the placenta and fetus.It is a non-invasive, immediate intervention that can potentially correct the issue of late decelerations quickly.

- C. Increase the infusion rate of the IV fluid.Increasing the infusion rate of IV fluids can improve maternal blood volume, potentially improving placental perfusion.However, this action is not as immediate in effect as repositioning the client and is considered a secondary measure.It may be used in conjunction with other actions but should not be the priority intervention for late decelerations.

- D. Elevate the client's legs.
Elevating the client's legs can increase venous return to the heart, potentially improving maternal cardiac output and placental blood flow.However, this action is less effective than lateral positioning in addressing uteroplacental insufficiency.It is not the first-line response for late decelerations and may not provide the immediate correction needed.
