Which of the following medications would you administer for an overdose of acetaminophen?
- A. Naloxone
- B. Vitamin K
- C. Acetylcysteine
- D. Atropine
Correct Answer: C
Rationale: Acetylcysteine is the specific antidote for acetaminophen overdose. Acetaminophen (also known as paracetamol) toxicity can cause severe liver damage if not treated promptly. Acetylcysteine works by replenishing the depleted glutathione stores in the liver, helping to prevent liver damage and improving the patient's outcome. Naloxone is used for opioid overdose, vitamin K for reversing the effects of certain anticoagulants, and atropine for specific heart and nerve related conditions.

Barium enema is a drug used for :
- A. diagnosis;
- B. prevention;
- C. contraception;
- D. stimulation ;
Correct Answer: A
Rationale: Barium enema is a diagnostic imaging test used to examine the large intestine (colon and rectum). It involves the administration of a contrast material containing barium into the colon through the rectum, followed by X-rays to produce clear images of the colon's lining. This procedure helps in the diagnosis of various conditions such as colon polyps, diverticulosis, colorectal cancer, and inflammatory bowel disease. Therefore, barium enema is primarily used for diagnostic purposes, not for prevention, contraception, stimulation, or treatment of conditions.

Which drug concentration is appropriate to administer in an order for epinephrine 0.3 mg IM to treat a severe allergic reaction in an adult patient?
- A. 1:10,000
- B. 0.736111111
- C. 0.111111111
- D. 1:10
Correct Answer: B
Rationale: The appropriate concentration for epinephrine 0.3 mg IM in an adult for a severe allergic reaction is 1:1000. This concentration is used for intramuscular administration, while 1:10,000 (A) is used for intravenous administration in cardiac arrest. Concentrations of 1:100 (C) and 1:10 (D) are not standard for this purpose.
Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
- A. Heparin
- B. Alprazola
- C. Digoxin
- D. Levothyroxine
Correct Answer: C
Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heartbeats. It works by increasing the force of contraction of the heart muscle, thereby increasing cardiac output. Additionally, digoxin also has the ability to slow down the heart rate, making it helpful in conditions such as atrial fibrillation. Heparin is an anticoagulant medication used to prevent blood clot formation, while Alprazolam is a benzodiazepine used to treat anxiety disorders. Levothyroxine is a thyroid hormone replacement medication to treat hypothyroidism. None of these drugs have the therapeutic effects of increasing cardiac output and slowing heart rate like digoxin.
The patient accidentally takes too much of the prescribed warfarin (Coumadin) and is readmitted to the hospital with bleeding. Which drug can the nurse anticipates administrating?
- A. Protamine sulfate
- B. Alteplase (Activase, Cathflo Activas
- D. Reteplase (Retavas
Correct Answer: D
Rationale: Warfarin, also known as Coumadin, is an anticoagulant medication that works by inhibiting the production of clotting factors in the liver, specifically factors II, VII, IX, and X. In the event of warfarin overdose, which can lead to excessive bleeding, the antidote is vitamin K. Vitamin K promotes the production of these clotting factors and helps reverse the effects of warfarin. Therefore, in this situation, the nurse can anticipate administering vitamin K to the patient to help stop the bleeding caused by the excess warfarin in the system.
