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.
A patient is receiving an IV infusion of a thrombolytic drug during treatment for an acute MI. The nurse notices that there is a slight amount of bleeding from the antecubital area where venous lab work was drawn. What will the nurse do first?
- A. Monitor the site for further bleeding.
- B. Apply pressure to the site with a gauze pa
- D. Slow the rate of infusion of the thrombolytic drug.
Correct Answer: B
Rationale: Applying pressure to the site with a gauze pad is the first action the nurse should take when noticing bleeding from the antecubital area. This will help control the bleeding and prevent further blood loss. Monitoring the site for further bleeding is important, but immediate intervention by applying pressure is necessary to address the issue. Slowing the rate of infusion of the thrombolytic drug or stopping the infusion should be considered if bleeding continues despite applying pressure or if there are signs of significant bleeding or hemorrhage.
Heparin is classified under what class?
- A. Laxative
- B. ACE inhibitor
- C. Anti-convulsant
- D. Antithrombotic
Correct Answer: D
Rationale: Heparin is classified as an antithrombotic agent. It is a medication that helps prevent blood clot formation by inhibiting the activity of certain clotting factors in the blood. Heparin is commonly used in the treatment and prevention of conditions such as deep vein thrombosis, pulmonary embolism, and during certain medical procedures to prevent clot formation. It is not classified as a laxative, ACE inhibitor, or anti-convulsant based on its mechanism of action and therapeutic use.
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.
A patient is experiencing mucositis (stomatitis) after receiving chemotherapy. Which symptomatic treatments will be appropriate? (Select all that apply.)
- A. Frequent mouth rinses
- B. Antiemetics
- C. Topical anesthetics
- D. Stress reduction
Correct Answer: A
Rationale: Mucositis, or stomatitis, is a painful inflammation of the mucous membranes caused by chemotherapy. Frequent mouth rinses with saline or baking soda solutions help keep the mouth clean and promote healing. Topical anesthetics, such as lidocaine, can provide pain relief. Stress reduction techniques, such as relaxation or mindfulness, may help manage the discomfort associated with mucositis. Antiemetics are used to control nausea and vomiting, which are not directly related to mucositis. Antibiotics are only necessary if there is a secondary infection, which is not mentioned in this scenario.
