A nurse is caring for a client who is in labor and has an external fetal monitor in place. The nurse observes late decelerations in the fetal heart rate. Which of the following findings should the nurse identify as the cause of late decelerations?

Correct Answer: B

Rationale: Late decelerations in the fetal heart rate are caused by uteroplacental insufficiency, which results from inadequate blood flow to the placenta. This leads to reduced oxygen and nutrients reaching the fetus during contractions. Choice A, fetal head compression, does not typically cause late decelerations but can result in variable decelerations. Choice C, umbilical cord compression, usually leads to variable decelerations. Choice D, fetal hypoxia, is a broad term and not the direct cause of late decelerations, which are specifically linked to uteroplacental insufficiency.

Correct Answer: B

Rationale: The correct answer is to assist the client to the left Sims' position when administering an enema. This position helps facilitate the flow of the enema solution into the rectum. Placing the client in a high-Fowler's position (Choice A) is not ideal for administering an enema. Inserting the enema tubing 2.5 cm (1 in) into the rectum (Choice C) is incorrect as it should be inserted 7.5-10 cm (3-4 in) for an adult. Lubricating the tip of the enema tubing with petroleum jelly (Choice D) is a correct step to ease insertion but is not the most critical action among the choices provided.

Correct Answer: B

Rationale: The correct answer is to inject the medication into the client's abdomen. Enoxaparin is a medication that should be administered subcutaneously into the abdomen to ensure proper absorption. Choice A is incorrect because enoxaparin should not be administered intramuscularly. Choice C is incorrect because massaging the injection site after administration is not recommended for enoxaparin injections. Choice D is incorrect because aspirating for blood return is not necessary before administering a subcutaneous injection like enoxaparin.

Correct Answer: A

Rationale: The correct answer is A. Taking omeprazole before meals is important as it improves the medication's effectiveness in reducing gastric acid production. Option B is incorrect as omeprazole should not be taken with antacids as it can interfere with its absorption. Option C is incorrect because omeprazole is usually recommended to be taken before breakfast, not at bedtime. Option D is incorrect as omeprazole is generally taken on an empty stomach, at least 1 hour before a meal.

Correct Answer: B

Rationale: Sanguineous drainage from the surgical site 48 hours after surgery could indicate a complication such as hemorrhage or infection and should be reported. Sanguineous drainage is typically seen in the early postoperative period due to the presence of blood. Serous drainage, on the other hand, is normal in the later stages of wound healing. A heart rate of 80/min is within the normal range for an adult. A temperature of 37.5°C (99.5°F) is slightly elevated but not a concerning finding in the absence of other symptoms.
