Med Surg Cardiovascular Practice Questions Questions
Question 1 of 5
The client has paroxysmal supraventricular tachycardia. What is the drug of choice to treat this condition?
Correct Answer: D
Rationale: The correct answer is D: Adenosine. Adenosine is the drug of choice for treating paroxysmal supraventricular tachycardia (PSVT) because it works by slowing down conduction through the AV node, effectively terminating the tachycardia. Flecainide (A) and lidocaine (B) are antiarrhythmic drugs used for ventricular arrhythmias, not PSVT. Metoprolol (C) is a beta-blocker that may be used for long-term management of PSVT but is not the first-line acute treatment like adenosine.
Question 2 of 5
The client is to be given warfarin. What is a contraindication to giving this drug?
Correct Answer: A
Rationale: The correct answer is A: Thrombocytosis. Warfarin is an anticoagulant that works by inhibiting blood clotting. Thrombocytosis is a condition where there is an excessive number of platelets in the blood, increasing the risk of blood clots. Giving warfarin to a patient with thrombocytosis can further increase the risk of bleeding complications. Summary of incorrect choices: B: Mild thrombocytopenia - This condition involves a low platelet count, which would actually make the patient more susceptible to blood clots, not a contraindication for warfarin. C: Lumbar puncture - This procedure involves obtaining cerebrospinal fluid and is not directly related to the use of warfarin. D: History of eye surgery in the distant past - This is not a contraindication for warfarin unless there were specific complications related to the surgery that would increase the risk of bleeding
Question 3 of 5
The client is taking a glycoprotein IIB/IIIA receptor antagonist for the prevention of stroke. What drug is the client likely taking?
Correct Answer: D
Rationale: The correct answer is D: Abciximab. Glycoprotein IIb/IIIa inhibitors like abciximab are used for preventing stroke in high-risk patients. These drugs block platelet aggregation by binding to the glycoprotein IIb/IIIa receptor. Plavix (A) and Ticlid (B) are antiplatelet drugs that work through different mechanisms and are not glycoprotein IIb/IIIa inhibitors. Aspirin (C) is also an antiplatelet drug but does not specifically target the glycoprotein IIb/IIIa receptor.
Question 4 of 5
The client is taking gemfibrozil. What drug-drug interaction does the nurse tell the client about?
Correct Answer: B
Rationale: The correct answer is B because gemfibrozil can potentiate the hypoglycemic effects of sulfonylurea drugs by displacing them from protein binding sites, leading to increased free drug levels. This interaction can result in dangerously low blood sugar levels. A: Gemfibrozil does not affect digoxin levels. C: Gemfibrozil does not lower theophylline levels. D: Gemfibrozil can be taken with cimetidine without significant drug-drug interactions.
Question 5 of 5
The nurse is assessing the client’s aortic valve. Where is the stethoscope placed to best hear the aortic valve?
Correct Answer: A
Rationale: The correct answer is A: Second intercostal space to the right of the sternum. This is the location of the aortic valve. The aortic valve is best heard at the second intercostal space on the right side of the sternum. The aortic valve is located at the level of the second right intercostal space. Placing the stethoscope at this specific location allows for optimal auscultation of the aortic valve. Choices B, C, and D are incorrect because they do not correspond to the correct anatomical location of the aortic valve. Placing the stethoscope at those locations would not provide the best assessment of the aortic valve.
