A nurse is providing discharge instructions to a client who has a new prescription for warfarin. Which of the following foods should the nurse advise the client to limit in their diet?
Spinach
Bananas
Cheese
Eggs
The Correct Answer is A
A) Correct. The nurse should advise the client to limit spinach in their diet as this food is high in vitamin K, which can antagonize the anticoagulant effect of warfarin and increase the risk of thrombosis.
B) Incorrect. The nurse should not advise the client to limit bananas in their diet as this food is high in potassium, which can help prevent hypokalemia that can occur with some anticoagulants such as heparin. Bananas do not affect the action of warfarin.
C) Incorrect. The nurse should not advise the client to limit cheese in their diet as this food is high in calcium, which can help prevent osteoporosis that can occur with long-term use of warfarin. Cheese does not affect the action of warfarin.
D) Incorrect. The nurse should not advise the client to limit eggs in their diet as this food is high in protein, which can help maintain muscle mass and wound healing that can be impaired by warfarin. Eggs do not affect the action of warfarin.

Correct Answer is C
Explanation
C) Incorrect. The client should avoid taking their medication with grapefruit juice as it can interfere with the metabolism of some antihypertensive drugs and increase the risk of adverse effects.
A) Correct. The client should not stop taking their medication even if they feel better as this can cause a rebound increase in blood pressure and worsen their condition.
B) Correct. The client should check their blood pressure regularly and record the readings to monitor their response to treatment and identify any changes that may require adjustment of their medication dose.
D) Correct. The client should inform their doctor if they experience any side effects from their medication such as dizziness, headache, fatigue, or cough, as these may indicate a need for a different drug or a lower dose.
Correct Answer is B
Explanation
B) Correct. The nurse should obtain a blood sample from the client for a complete blood count as these symptoms can indicate agranulocytosis, a potentially fatal adverse effect of clozapine that causes a severe decrease in white blood cells and increases the risk of infection.
A) Incorrect. The nurse should not administer acetaminophen to the client as this drug can mask the signs of infection and delay diagnosis and treatment of agranulocytosis.
C) Incorrect. The nurse should encourage the client to drink plenty of fluids and rest, but this action alone would not address the potential serious adverse effect of agranulocytosis associated with clozapine. Obtaining a blood sample for a complete blood count is necessary to assess the client's white blood cell count and determine if agranulocytosis is present.
D) Incorrect. Discontinuing clozapine and notifying the provider is important, but it should be done after obtaining a blood sample for a complete blood count to confirm the presence of agranulocytosis. This allows for appropriate medical management and alternative treatment options to be initiated.
