Correct Answer: D

Rationale: Administering methylergonovine intramuscularly helps contract the uterus, reducing the risk of postpartum hemorrhage. Monitoring for signs of infection (Choice A) is important but not directly related to preventing postpartum hemorrhage. Uterine massage (Choice B) is beneficial to prevent uterine atony, but methylergonovine is a more specific intervention to prevent hemorrhage. Applying ice packs to the perineum (Choice C) is helpful for perineal pain and swelling, not for preventing postpartum hemorrhage.

Correct Answer: D

Rationale: The correct answer is D. A WBC count of 14,000/mm³ is elevated, indicating a potential infection or inflammation, and should be reported to the provider for further evaluation and management. Choices A, B, and C are within normal ranges and do not require immediate reporting as they indicate normal hemoglobin, platelet count, and hematocrit levels for a school-age child.

Correct Answer: A

Rationale: Corrected Rationale: Bradypnea, or slow breathing, is a common sign of opioid toxicity. When a client is experiencing opioid toxicity, the respiratory system is usually the most affected, leading to a decrease in the respiratory rate (bradypnea). Tachycardia (increased heart rate), hypertension (high blood pressure), and diaphoresis (excessive sweating) are not typical manifestations of opioid toxicity. Therefore, the correct answer is bradypnea.

Correct Answer: D

Rationale: The correct answer is D: Elevated temperature. Cocaine is a stimulant drug that can lead to an increase in body temperature. Hypotension (choice A) is less likely as cocaine tends to increase blood pressure. Memory loss (choice B) and slurred speech (choice C) are not typically immediate effects of recent cocaine use.

Correct Answer: D

Rationale: The correct action the nurse should take is to flush the tube with 0.9% sodium chloride every 4 hours. This helps maintain patency and prevents clogs during enteral feedings. Keeping the head of the bed elevated to 15 degrees (Choice A) is important for preventing aspiration but is not directly related to tube care. Changing the feeding bag every 48 hours (Choice B) is not a standard practice as the bag should be changed every 24 hours to prevent bacterial growth. Administering the feeding through a large-bore syringe (Choice C) is incorrect as enteral feedings should be given through an appropriate feeding pump for accuracy and safety.
