1. A client has a new prescription for Folic Acid. Which of the following instructions should the nurse include?

A. Take the medication with food.
B. Expect a metallic taste in your mouth.
C. Increase your intake of green, leafy vegetables.
D. Avoid citrus fruits.

Correct answer: C

Rationale: The correct answer is C: 'Increase your intake of green, leafy vegetables.' Folic acid is naturally found in green, leafy vegetables. By increasing the intake of these vegetables, the client can supplement their folic acid levels. This dietary adjustment supports the client in meeting the prescription requirements and enhances the overall health benefits of folic acid. Choices A, B, and D are incorrect because they do not directly relate to increasing folic acid intake as required by the prescription.

2. A client has a new prescription for Furosemide. Which of the following instructions should be included?

A. Take this medication at bedtime.
B. Avoid eating foods high in potassium.
C. Change positions slowly.
D. Take this medication with meals.

Correct answer: C

Rationale: Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and falls. Instructing the client to change positions slowly helps prevent these adverse effects by allowing the body to adjust to postural changes gradually, reducing the risk of significant blood pressure drops upon standing up quickly.

3. When taking Digoxin, low levels of what can cause toxicity?

A. Potassium
B. Calcium
C. Sodium
D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

4. Which of the following drugs is associated with the reaction of Cinchonism?

A. Valproic acid
B. Quinidine
C. Isoniazid
D. Ethosuximide

Correct answer: B

Rationale: Cinchonism is associated with Quinidine, not Valproic acid, Isoniazid, or Ethosuximide. Cinchonism is characterized by symptoms such as tinnitus, dizziness, and headaches. Quinidine, being an antiarrhythmic agent, can lead to this condition as a side effect.

5. What does it mean when a medication has a half-life?

A. It only lasts for 30 minutes after the medication is given
B. How long it takes for half of the dose to be eliminated from the bloodstream
C. It is the peak of how effective the medicine is
D. Drug is greatly reduced before it reaches the systemic circulation

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.
