Question 1 of 5
A patient has overdosed on Warfarin, what should be given to the patient to be reveresed?
Correct Answer: D
Rationale: Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the body. Overdosing on warfarin can lead to excessive bleeding due to the lack of functional clotting factors. To reverse the effects of warfarin overdose, Vitamin K is given because it helps the body restore the levels of clotting factors that were reduced by warfarin. Vitamin K promotes the synthesis of clotting factors II, VII, IX, and X, which allows the blood to clot effectively again. Therefore, in the case of a warfarin overdose, Vitamin K is the appropriate antidote to help reverse the anticoagulant effects.

Question 3 of 5
A patient has been receiving intravenous heparin. When laboratory tests are drawn, the nurse has difficulty
Correct Answer: C
Rationale: Protamine sulfate is the specific antidote for heparin, which is used to reverse the effects of heparin in cases of bleeding or elevated PTT/aPTT levels. It works by binding to heparin, neutralizing its anticoagulant activity. Therefore, in this scenario where the patient is experiencing bloody stools, abdominal pain, and has elevated PTT/aPTT levels, the appropriate action for the nurse to take is to obtain an order for protamine sulfate to reverse the effects of heparin. This will help normalize the patient's coagulation profile and manage any bleeding complications associated with heparin therapy.
Question 4 of 5
Nonselective adrenergic blocking agents have a variety of therapeutic uses. Which agent is used for the treatment of heart failure?
Correct Answer: A
Rationale: Carvedilol is available orally and is used to treat hypertension as well as congestive heart failure and left ventricular dysfunction after a myocardial infarction. Sotalol is a nonselective beta-adrenergic blocking agent used to treat potentially life-threatening ventricular arrhythmias and to maintain normal sinus rhythm in patients with atrial fibrillation or flutter. Propranolol is a nonselective beta-adrenergic blocking agent used for treatment of hypertension, angina, idiopathic hypertrophic subaortic stenosis (IHSS) induced palpitations, angina and syncope, some cardiac arrhythmias induced by catecholamines or digoxin, pheochromocytoma; prevention of reinfarction after myocardial infarction; prophylaxis for migraine headache (which may be caused by vasodilation and is relieved by vasoconstriction, although the exact action is not clearly understood); prevention of stage fright (which is a sympathetic stress reaction to a particular situation); and treatment of essential tremors. Tamsulosin is used to treat benign prostatic hyperplasia and is an alpha1-selective adrenergic blocking agent.
