A nurse is teaching a client who has a new prescription for warfarin. Which of the following statements by the client indicates a need for further teaching?
I will avoid eating foods that are high in vitamin K.
I will use an electric razor for shaving.
I will check my blood pressure regularly.
I will report any signs of bleeding or bruising.
The Correct Answer is A
A) Incorrect. The client should eat a consistent amount of foods that are high in vitamin K, such as leafy greens, broccoli, and cabbage. Vitamin K can interfere with the anticoagulant effect of warfarin and increase the risk of clotting.
B) Correct. The client should use an electric razor for shaving to prevent cuts and bleeding.
C) Correct. The client should check their blood pressure regularly to monitor for hypertension, which can increase the risk of bleeding complications.
D) Correct. The client should report any signs of bleeding or bruising to their provider, as they may indicate a high INR level or a bleeding disorder.

Correct Answer is C
Explanation
A) Incorrect. Extrapyramidal symptoms (EPS), such as dystonia, akathisia, and tardive dyskinesia, are caused by dopamine antagonists, such as haloperidol. However, these symptoms are not related to the combination of medications that the client is taking.
B) Incorrect. Serotonin syndrome is a potentially life-threatening condition that results from excessive serotonin activity in the central nervous system. It is caused by serotonin-enhancing medications, such as antidepressants, opioids, and triptans. None of the medications that the client is taking have this effect.
C) Correct. Neuroleptic malignant syndrome (NMS) is a rare but serious condition that occurs due to dopamine blockade in the brain and peripheral tissues. It is caused by antipsychotic medications, such as haloperidol. The risk of NMS is increased when lithium carbonate is added to antipsychotic therapy, as lithium can potentiate the dopamine-blocking effect of antipsychotics.
D) Incorrect. Lithium toxicity is a condition that occurs when lithium levels exceed the therapeutic range of 0.6 to 1.2 mEq/L. It is caused by factors that affect lithium excretion, such as dehydration, renal impairment, drug interactions, and overdose. None of the other medications that the client is taking interact with lithium or affect its excretion.
