1. What is the antidote for Warfarin?
- A. Naloxone
- B. Vitamin K
- C. Glucagon
- D. Vitamin B
Correct answer: B
Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.
2. A client is prescribed Ciprofloxacin and seeks guidance from a nurse. Which instruction should the nurse provide?
- A. Take this medication with meals.
- B. Avoid taking this medication with dairy products.
- C. Take this medication at bedtime.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct answer is B: 'Avoid taking this medication with dairy products.' Ciprofloxacin should not be taken with dairy products due to the interference of calcium with medication absorption. Taking Ciprofloxacin 1 hour before or 2 hours after consuming dairy products ensures optimal effectiveness. Choice A is incorrect because Ciprofloxacin is usually taken on an empty stomach or with a light meal, not necessarily with heavy meals. Choice C is incorrect as there is no specific instruction to take Ciprofloxacin at bedtime. Choice D is incorrect because there is no need to increase potassium-rich foods intake specifically related to Ciprofloxacin use.
3. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?
- A. Press your finger on the inside corner of your eye for 1 minute after application.
- B. Apply the eye drops directly on the cornea.
- C. Drop the prescribed amount of medication into the center of the conjunctival sac.
- D. Wipe your eyes gently with a tissue immediately after application.
Correct answer: C
Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.
4. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?
- A. Sodium
- B. Potassium
- C. Magnesium
- D. Calcium
Correct answer: B
Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.
5. 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.
