Flashcards Cardiology 1-5 focused

A patient presents with shortness of breath, fatigue, and fluid buildup. Using your understanding of cardiovascular conditions, reason through which condition is most likely responsible and explain why.

• Hypertension, because it directly causes fluid retention in the lungs.

• Heart Failure, because the heart cannot pump effectively, leading to these symptoms.

• Arrhythmias, because abnormal heart rhythms always cause fluid buildup.

• Coronary Artery Disease, because it only causes chest pain and not fluid buildup.

Given a patient with elevated blood pressure, explain the potential long-term risks and justify why managing this condition is crucial in pharmacology.

• Only risk is chest pain, so management is not crucial.

• Risks include heart attack, stroke, and kidney disease, making management vital.

• Only risk is fainting, so management is not important.

• Risks are limited to fatigue, so management is optional.

A person experiences palpitations and fainting episodes. Using strategic reasoning, determine which cardiovascular condition is most likely and discuss the potential consequences if left untreated.

• Hypertension; consequences are only mild headaches.

• Arrhythmias; consequences can include sudden cardiac death.

• Heart Failure; consequences are limited to chest pain.

• Coronary Artery Disease; consequences are only shortness of breath.

Analyze why understanding the cardiovascular system is considered vital in pharmacology, especially in the context of managing multiple conditions.

• Because it only affects the delivery of oxygen, not nutrients.

• Because it plays a crucial role in circulating blood and delivering nutrients, impacting conditions like hypertension, heart failure, arrhythmias, and coronary artery disease.

• Because it is only important for treating infections.

• Because it is unrelated to the management of chronic diseases.

A patient with hypertension is not responding well to beta-blockers and diuretics. Using your knowledge of antihypertensive drug classes, propose an alternative pharmacological approach and justify your choice based on the mechanisms of action.

• Prescribe an ACE inhibitor, as it reduces blood pressure by inhibiting the conversion of angiotensin I to angiotensin II.

• Increase the dose of beta-blockers, as higher doses always improve efficacy.

• Switch to antiarrhythmic drugs, as they are primarily used for hypertension.

• Use nitrates, as they are the first-line treatment for hypertension.

A patient with heart failure is already on diuretics and beta-blockers but continues to have symptoms. Strategically select an additional drug class from the list provided and explain your reasoning.

• Add an angiotensin II receptor blocker (ARB) to further reduce afterload and improve cardiac function.

• Add nitrates, as they are primarily used for arrhythmias.

• Add sodium channel blockers, as they are the mainstay for heart failure.

• Add calcium channel blockers, as they are always preferred in heart failure.

A patient presents with arrhythmia and has a history of adverse reactions to beta-blockers. Using strategic reasoning, which alternative drug class would you consider and why?

• Sodium channel blockers, as they can help stabilize cardiac electrical activity.

• Diuretics, as they are the primary treatment for arrhythmias.

• Nitrates, as they are the first-line therapy for arrhythmias.

• ACE inhibitors, as they directly control heart rhythm.

A patient with angina is already taking nitrates but continues to experience chest pain. Based on the pharmacological options listed, which additional class of drugs could be added, and what is the rationale for your choice?

• Add a calcium channel blocker to reduce myocardial oxygen demand and improve coronary blood flow.

• Add a diuretic, as it is the mainstay for angina.

• Add an ACE inhibitor, as it is the first-line for angina.

• Add a sodium channel blocker, as it is primarily used for angina.

A patient with hypertension is prescribed a medication that reduces systemic vascular resistance and decreases blood volume. Using your understanding of pharmacological mechanisms, explain how this medication helps in lowering blood pressure and identify which class of drugs it belongs to.

• It increases cardiac output and belongs to heart failure medications.

• It modifies electrical impulses and belongs to antiarrhythmics.

• It reduces systemic vascular resistance and blood volume, and belongs to antihypertensives.

• It increases blood flow to the heart muscle and belongs to antianginals.

A patient with heart failure is given a medication that improves cardiac output, reduces preload and afterload, and modulates neurohormonal systems. Strategically reason how these combined effects contribute to improved heart function.

• By increasing blood flow to the heart muscle and reducing oxygen demand.

• By restoring normal rhythm and rate through electrical impulse modification.

• By improving the heart’s pumping efficiency and reducing the workload on the heart, thus enhancing overall heart function.

• By decreasing systemic vascular resistance and lowering blood pressure.
