Med Surg Cardiovascular Practice Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The client has an EKG showing a gradually lengthening PR interval and a dropped QRS at the longest PR interval. What rhythm does the client have?
Correct Answer: A
Rationale: The correct answer is A: Third degree AV block. In this condition, there is complete dissociation between the atria and ventricles, leading to independent rhythms. The gradually lengthening PR interval followed by a dropped QRS complex is characteristic of third degree AV block. The atria and ventricles are firing independently, resulting in no association between the P waves and QRS complexes. Choices B, C, and D do not match the description provided and do not involve complete dissociation between the atria and ventricles as seen in third degree AV block.
Question 5 of 5
The nurse is admitting a patient who has chest pain. Which assessment data suggest that the pain is caused by an acute myocardial infarction (AMI)?
Correct Answer: B
Rationale: The correct answer is B because chest pain lasting longer than 30 minutes is a key indicator of an acute myocardial infarction (AMI) due to the prolonged ischemia of the heart muscle. Choice A is incorrect because chest pain increasing with deep breathing is more indicative of pleuritic chest pain, not AMI. Choice C is incorrect because relief with nitroglycerin suggests the pain is due to angina, not AMI. Choice D is incorrect because reproducible pain with arm movement is more likely musculoskeletal in nature, not related to AMI.
