Question 1 of 5
Warfarin (Coumadin) is an anticoagulant and interferes with the action of:
Correct Answer: B
Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.
Question 2 of 5
A patient is prescribed an oral anticoagulant. What should the nurse monitor for?
Correct Answer: C
Rationale: Correct! When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants are medications that prevent blood clot formation but can increase the risk of bleeding. Monitoring for signs such as easy bruising, blood in urine or stool, and prolonged bleeding from minor cuts is essential. Choices A, B, and D are incorrect because oral anticoagulants do not typically affect blood glucose levels, blood pressure, or appetite.
Question 3 of 5
For a patient on lithium therapy, which dietary recommendation is essential?
Correct Answer: B
Rationale: The correct answer is to increase sodium intake. For patients on lithium therapy, maintaining consistent sodium intake is crucial to avoid fluctuations in drug levels. Increasing caffeine intake (choice A) is not recommended as it can interfere with lithium levels. While protein intake (choice C) is important for overall health, it is not specifically essential for patients on lithium therapy. Similarly, increasing fiber intake (choice D) is beneficial but not a primary concern for patients on lithium therapy.
Question 4 of 5
A patient with a history of peptic ulcer disease should avoid which medication?
Correct Answer: C
Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.
Question 5 of 5
A patient with hypothyroidism should be advised to consume more of which nutrient?
Correct Answer: B
Rationale: The correct answer is B: Iodine. Iodine is crucial for the production of thyroid hormones. A deficiency in iodine can lead to hypothyroidism. Calcium (Choice A) is important for bone health but is not directly related to thyroid function. Vitamin C (Choice C) is essential for the immune system and skin health but does not play a significant role in thyroid function. Iron (Choice D) is vital for red blood cell production and oxygen transport but is not specifically relevant to hypothyroidism.
