Correct Answer: A

Rationale: The correct instruction for a client prescribed ferrous sulfate is to take the medication with orange juice to enhance absorption. Orange juice is recommended because of its vitamin C content, which aids in the absorption of iron. Choice B, taking the medication on an empty stomach, is incorrect because ferrous sulfate is better absorbed with food. Choice C, taking the medication with milk if it causes stomach upset, is incorrect as calcium in milk can interfere with iron absorption. Choice D, taking the medication at bedtime, is incorrect as it is usually recommended to take iron supplements between meals or with food to enhance absorption.

Correct Answer: B

Rationale: The correct answer is B: Ammonia 145 mcg/dL. An elevated ammonia level can indicate hepatic encephalopathy in clients with liver cirrhosis, leading to confusion. Bilirubin (Choice A) is within the normal range, indicating adequate liver function. Albumin (Choice C) and Hemoglobin (Choice D) levels are also within normal limits and are not directly related to the client's confusion in this scenario.

Correct Answer: C

Rationale: The correct action the nurse should include in the care plan for a client with thrombocytopenia is to provide the client with a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to increased bleeding tendencies. Providing a stool softener helps prevent constipation and straining during bowel movements, reducing the risk of bleeding. Encouraging the client to floss daily (Choice A) is important for oral hygiene but is not directly related to managing thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is more related to preventing infections in immunocompromised clients. Avoiding serving raw vegetables (Choice D) is important for clients with compromised immune systems but is not specifically targeted at managing thrombocytopenia.

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 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.
