Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy.

Rationale: The correct answer is to avoid close contact with pregnant women for one week. This precaution is essential to prevent radiation exposure to vulnerable populations. Pregnant women and small children are more sensitive to radiation, making it crucial for patients undergoing radioactive iodine therapy to avoid close contact with them for a specified period.

Rationale: The correct advice for the administration of ferrous sulfate is to take it on an empty stomach for best absorption. This enhances the absorption of iron. If gastrointestinal upset occurs, the medication can be taken with food. Taking ferrous sulfate with dairy products or before bedtime is not recommended. Vitamin C can actually help with the absorption of iron and is often recommended to be taken alongside iron supplements to enhance absorption.

Correct Answer: D

Rationale: The correct action for the nurse to include on the care plan for a patient with a calcium level of 12.1 mg/dL is to encourage fluid intake up to 4000 mL every day. This is essential to decrease the risk for renal calculi associated with hypercalcemia. While bed rest is not necessary, ambulation is encouraged to help decrease the loss of calcium from the bone. Monitoring for Trousseau's and Chvostek's signs is more relevant when hypocalcemia is suspected. Auscultating lung sounds every shift is a routine assessment, not required every 4 hours unless there is a specific respiratory concern.

Correct Answer: B

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. To minimize this risk, patients with thrombocytopenia should avoid activities that can cause injury or bleeding, such as intramuscular injections. Encouraging light exercise can be beneficial, as it promotes circulation without increasing the risk of trauma. Aspirin should be avoided as it can further impair platelet function. Additionally, using a soft toothbrush for oral care is recommended to prevent gum bleeding in patients with thrombocytopenia.
