1. When caring for a client prescribed Digoxin, which finding should the nurse monitor to assess for potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hypoglycemia
• D. Hypercalcemia

Correct answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxic effects such as bradycardia, which is a slow heart rate. Therefore, the nurse should closely monitor the client's heart rate for any significant decreases, as this could indicate Digoxin toxicity and prompt further intervention. Choices B, C, and D are incorrect because Digoxin toxicity typically presents with bradycardia, not hypertension, hypoglycemia, or hypercalcemia.

2. 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.

3. A healthcare provider is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.

4. A client is receiving IV Dopamine for the treatment of shock. Which of the following findings indicates that the medication is effective?

• A. Increased heart rate
• B. Decreased blood pressure
• C. Increased urine output
• D. Decreased respiratory rate

Correct answer: C

Rationale: The correct answer is increased urine output. Dopamine increases cardiac output and improves renal perfusion, leading to increased urine output. This response indicates that the medication is effective in treating shock by enhancing renal function and perfusion. Choices A, B, and D are incorrect because an increased heart rate, decreased blood pressure, and decreased respiratory rate are not findings that indicate the effectiveness of IV Dopamine in treating shock.

5. Which drug is the antidote for Alprazolam?

• A. Physostigmine
• B. Protamine sulfate
• C. Flumazenil
• D. Acetylcysteine

Correct answer: C

Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.
