1. What is the antidote for Heparin?

A. Protamine sulfate
B. Vitamin K
C. Naloxone
D. Toradol

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant that prevents blood clotting. Protamine sulfate is the antidote for Heparin as it binds to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another anticoagulant. Naloxone is an opioid antagonist for opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) for pain relief. Therefore, the correct antidote for Heparin is Protamine sulfate.

2. 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.

3. A nurse is providing discharge instructions for a client who has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?

A. Take the medication before bed.
B. Monitor for increased blood pressure.
C. Take the medication on an empty stomach.
D. Monitor for leg cramps.

Correct answer: D

Rationale: The correct answer is D: 'Monitor for leg cramps.' Leg cramps may indicate hypokalemia, an adverse effect of hydrochlorothiazide, and should be reported to the provider. Choice A is incorrect because hydrochlorothiazide is usually taken in the morning to avoid nocturia. Choice B is incorrect as hydrochlorothiazide is a diuretic that helps lower blood pressure. Choice C is incorrect as hydrochlorothiazide can be taken with or without food.

4. A healthcare provider is caring for a client who has a new prescription for Epoetin Alfa. Which of the following laboratory values should the healthcare provider monitor?

A. WBC count.
B. Platelet count.
C. Hemoglobin.
D. Serum potassium.

Correct answer: C

Rationale: Epoetin alfa is a medication that stimulates red blood cell production, so hemoglobin levels should be monitored to assess the effectiveness of the drug. Monitoring hemoglobin levels helps evaluate the response to Epoetin Alfa treatment and ensures that the client's anemia is being appropriately managed.

5. A patient has been taking hydrocodone, an opioid analgesic for their moderate pain, and they have taken more than the prescribed dose. What should you administer as the antidote if they experience toxicity?

A. Naloxone
B. N-acetylcysteine
C. Atropine
D. Digoxin immune Fab

Correct answer: A

Rationale: Naloxone is the specific antidote for opioid toxicity. It works by blocking the effects of opioids on the central nervous system, thereby reversing symptoms like respiratory depression and sedation. N-acetylcysteine is used for acetaminophen overdose, while atropine is indicated for certain types of poisonings. Digoxin immune Fab is used for digoxin toxicity. Therefore, in the case of opioid toxicity due to hydrocodone overdose, naloxone is the appropriate antidote.
