Correct Answer: B
Rationale: Protamine is the antidote for Heparin. Heparin is an anticoagulant medication that works by increasing the activity of antithrombin III, leading to the inhibition of clotting factors. In cases of excessive bleeding or overdose with Heparin, protamine can be administered to neutralize its anticoagulant effects. Protamine works by binding to heparin to form a stable complex, thereby reversing the anticoagulant activity of Heparin. It is important for healthcare providers to be familiar with the antidotes for various medications to manage potential complications effectively.
Question 2 of 5
The nurse notes in the patient™s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?
Correct Answer: C
Rationale: The primary goal of anticoagulant therapy is to prevent the formation of blood clots or thrombus. Anticoagulants work by inhibiting the coagulation cascade, which ultimately prevents the blood from clotting too easily. By preventing the formation of clots, anticoagulant therapy helps reduce the risk of conditions such as deep vein thrombosis, pulmonary embolism, stroke, and heart attack, which are all associated with blood clot formation. Anticoagulant therapy does not stabilize or dissolve existing clots but rather focuses on preventing new clots from forming. Dilating the vessel around a clot is not the primary purpose of anticoagulant therapy.
Question 3 of 5
A patient wants to take garlic tablets to improve his cholesterol levels. Which condition would be a contraindication?
Correct Answer: D
Rationale: Scheduled surgery would be a contraindication for taking garlic tablets because garlic has blood-thinning properties that could potentially increase the risk of bleeding during or after surgery. This can interfere with the blood's ability to clot properly, leading to excessive bleeding and other complications during the surgical procedure. It is important to inform healthcare providers about all supplements being taken, including garlic tablets, before undergoing any surgery to ensure patient safety.
Question 4 of 5
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?
Correct Answer: D
Rationale: In the scenario described where the patient has accidentally taken too much warfarin (Coumadin) and is experiencing bleeding, the nurse can anticipate administering Vitamin K. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the liver. By administering Vitamin K, it helps reverse the anticoagulant effect of warfarin by supplying the needed vitamin K for the production of clotting factors. This aids in the clotting process and helps to stop the bleeding that may occur due to excess warfarin in the system. Other medications listed (such as Protamine sulfate, Alteplase, Reteplase) are not specific antidotes for warfarin overdose-related bleeding but are used for different therapeutic purposes.
Question 5 of 5
The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician?
Correct Answer: D
Rationale: Diphenhydramine, a first-generation antihistamine, has anticholinergic effects, including urinary hesitancy , due to reduced bladder contractility. This can escalate to retention, a serious issue, especially in older adults or those with prostate issues, warranting physician reporting. Sedation is expected and manageable, not typically reported unless severe. Diarrhea isn't common; constipation is more likely. Projectile vomiting suggests a different pathology, not a typical antihistamine effect. The nurse teaches reporting urinary hesitancy as it's a significant anticholinergic complication requiring intervention, making choice D the priority symptom to monitor.
