1. 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.

2. A client has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Tachycardia
• B. Hyperglycemia
• C. Hyponatremia
• D. Constipation

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use. Therefore, the correct answer is A: Tachycardia.

3. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?

• A. Remove the patch each evening.
• B. Do not cut the patch in half even if angina attacks are under control.
• C. Remove the nitroglycerin patch for 30 minutes if a headache occurs.
• D. Apply a new patch every 48 hours.

Correct answer: A

Rationale: The correct instruction for a client using a Nitroglycerin transdermal patch is to remove the patch each evening to prevent tolerance. This allows for a nitrate-free period of 10 to 12 hours during each 24-hour period, reducing the risk of developing tolerance to the medication. Choice B is incorrect because cutting the patch could alter the dose delivery and is not recommended. Choice C is incorrect as removing the patch for 30 minutes when a headache occurs may not be effective in managing symptoms. Choice D is incorrect as Nitroglycerin patches are usually applied once daily, not every 48 hours.

4. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?

• A. Naloxone
• B. Vitamin K
• C. Digibind
• D. Flumazenil

Correct answer: C

Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.

5. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?

• A. Hemoglobin
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.
