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 effect of sulfonylurea drugs, leading to low blood sugar levels. This interaction is important to prevent hypoglycemia in patients taking both medications. Other choices are incorrect because gemfibrozil does not significantly affect digoxin levels (A), theophylline levels (C), or interact with cimetidine (D) in a clinically significant manner.

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 a gradual lengthening of the PR interval and eventual dropped QRS complex. This indicates that the atria and ventricles are beating independently. Type 2 second degree AV block (B) presents with intermittent dropped QRS complexes without PR interval prolongation. Type 1 second degree AV block (C) displays a progressive prolongation of the PR interval until a dropped QRS complex occurs. Junctional escape rhythm (D) would not be consistent with the EKG findings of a gradually lengthening PR interval.

Correct Answer: B

Rationale: The correct answer is B because chest pain lasting longer than 30 minutes is a hallmark symptom of an acute myocardial infarction (AMI). This prolonged duration indicates potential heart tissue damage. Choice A is incorrect as pain worsening with deep breathing is more indicative of musculoskeletal issues. Choice C is incorrect as relief with nitroglycerin suggests angina, not AMI. Choice D is incorrect as reproducible pain with arm movement is more indicative of musculoskeletal issues.

Correct Answer: C

Rationale: The correct answer is C: “What time did your chest pain begin?” This question is crucial for determining if the patient is a candidate for thrombolytic therapy as the time of symptom onset is a key factor in deciding the eligibility for this treatment. Thrombolytic therapy is most effective when administered within a specific timeframe from the onset of symptoms, typically within the first few hours of symptom onset. Therefore, knowing the exact time when the chest pain started will help healthcare providers assess if the patient falls within the window of opportunity for thrombolytic therapy. Choices A, B, and D are incorrect because they do not directly address the time-sensitive nature of thrombolytic therapy eligibility. Allergies and daily aspirin intake are important considerations in healthcare, but they are not immediate factors in determining thrombolytic therapy candidacy. The pain rating on a scale of 0 to 10 is subjective and does not provide specific information regarding the urgency of thrombolytic therapy

Correct Answer: A

Rationale: The correct answer is A: when cardiac rehabilitation will begin. This is important teaching for a patient following an AMI and PCI as cardiac rehabilitation plays a crucial role in improving recovery and reducing the risk of future cardiac events. It helps in improving physical strength, managing stress, and promoting overall heart health. By educating the patient about the timing and benefits of cardiac rehabilitation, the nurse is empowering the patient to actively participate in their recovery process. Incorrect choices: B: The typical emotional responses to AMI - While emotional support is important, teaching about emotional responses may not be as crucial as focusing on physical recovery through cardiac rehabilitation. C: Information regarding discharge medications - Important, but not as immediate as cardiac rehabilitation for post-AMI recovery. D: The pathophysiology of coronary artery disease - While education is important, understanding the pathophysiology may not be as pressing as knowing when to start cardiac rehabilitation for immediate recovery.
