1. What is the pharmacological class of Lithium?
- A. Antidiabetics, biguanides
- B. Mood stabilizers
- C. Antiarrhythmics, anticonvulsants
- D. Vascular headache suppressants
Correct answer: B
Rationale: Lithium is classified as a mood stabilizer due to its primary use in managing bipolar disorder, where it helps stabilize mood swings and prevent episodes of mania and depression. While it can have other effects on the body, its main therapeutic role lies in its mood-stabilizing properties. Choices A, C, and D are incorrect as lithium is not classified as antidiabetics, biguanides, antiarrhythmics, anticonvulsants, or vascular headache suppressants. Its main pharmacological class is mood stabilizers.
2. A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
- A. Monitor for signs of bleeding.
- B. Avoid taking the medication with food.
- C. Expect to have increased urination.
- D. Take the medication with an antacid.
Correct answer: A
Rationale: Corrected Rationale: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. The client should monitor for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stool, and report them promptly to their healthcare provider for further evaluation and management. Choice B is incorrect because Clopidogrel can be taken with or without food. Choice C is incorrect as increased urination is not a common side effect of Clopidogrel. Choice D is incorrect as taking Clopidogrel with an antacid may reduce its effectiveness.
3. A client is being discharged with a new prescription for furosemide 40 mg PO daily. Which of the following instructions should be included?
- A. Avoid foods rich in potassium.
- B. Take the medication with food.
- C. Weigh yourself daily.
- D. Stand up slowly to minimize orthostatic hypotension.
Correct answer: D
Rationale: The correct answer is D: 'Stand up slowly to minimize orthostatic hypotension.' Clients prescribed furosemide are at risk for orthostatic hypotension, a sudden drop in blood pressure when changing positions. Advising the client to stand up slowly can help prevent this complication. Instructing the client to avoid rapid position changes decreases the likelihood of dizziness or fainting episodes. Choices A, B, and C are incorrect because furosemide does not require avoiding potassium-rich foods, taking the medication with food, or daily weighing as specific instructions.
4. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?
- A. Avoid consuming foods high in vitamin K.
- B. Monitor your blood pressure regularly.
- C. Increase your intake of green, leafy vegetables.
- D. Take the medication with a high-fat meal.
Correct answer: A
Rationale: The correct answer is to advise the client to avoid consuming foods high in vitamin K. Warfarin's effectiveness can be affected by vitamin K intake. Clients should maintain a consistent intake of vitamin K and avoid sudden increases in foods high in vitamin K to ensure the medication works properly and consistently. Choices B, C, and D are incorrect. Monitoring blood pressure, increasing intake of green, leafy vegetables, or taking the medication with a high-fat meal are not specific instructions related to Warfarin therapy.
5. What is the primary action of warfarin as an anticoagulant?
- A. Prevents the formation of blood clots
- B. Dissolves existing blood clots
- C. Dilates coronary arteries
- D. Treats rhythm disturbances
Correct answer: A
Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
