1. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

2. A client has a new prescription for Prednisone. Which of the following laboratory values should the nurse monitor?

• A. Serum potassium
• B. Serum calcium
• C. Serum sodium
• D. Serum glucose

Correct answer: D

Rationale: The correct answer is D, Serum glucose. Prednisone is a corticosteroid that can lead to hyperglycemia. Monitoring serum glucose levels is essential to assess for elevated blood sugar levels. Choices A, B, and C are incorrect as Prednisone does not directly affect potassium, calcium, or sodium levels.

3. When caring for a school-age child with a new prescription for Atomoxetine, the nurse should monitor the client for which of the following adverse effects of this medication?

• A. Kidney toxicity
• B. Liver damage
• C. Seizure activity
• D. Adrenal insufficiency

Correct answer: B

Rationale: The correct answer is B: Liver damage. Atomoxetine can lead to liver damage as an adverse effect. Symptoms of liver damage include jaundice, upper abdominal tenderness, dark urine, and elevated liver enzymes. Monitoring for these signs is crucial when a child is on this medication. Choices A, C, and D are incorrect because Atomoxetine is not known to cause kidney toxicity, seizure activity, or adrenal insufficiency as primary adverse effects.

4. What is the antidote for copper toxicity?

• A. Glucagon
• B. Aminocaproic acid
• C. Atropine
• D. Penicillamine

Correct answer: D

Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.

5. A client with deep vein thrombosis has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?

• A. Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
• B. I will call the provider to get a prescription for discontinuing the IV heparin today.
• C. Both heparin and warfarin work together to dissolve the clots.
• D. The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay.

Correct answer: A

Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.
