ACE inhibitors are protective to the heart in all of the following ways, EXCEPT:
-
Decrease vascular resistance
-
Decrease venous tone
-
Increase Na retention
-
Decrease BP
Correct Answer
A. Increase Na retentionExplanation
ACE inhibitors are medications that work by inhibiting the action of the enzyme ACE, which is responsible for converting angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, so by inhibiting its production, ACE inhibitors can decrease vascular resistance and lower blood pressure. Additionally, ACE inhibitors can also decrease venous tone, further reducing the workload on the heart. However, ACE inhibitors do not increase sodium retention. In fact, they can have a mild diuretic effect, promoting the excretion of sodium and water from the body. Therefore, the correct answer is that ACE inhibitors do not increase Na retention.Rate this question:

Your pt is on Enalapril and is complaining of a dry cough. She states that she would prefer not to take this medication anymore. What is an appropriate substitute?
-
Spironolactone
-
Metoprolol
-
Aspirin
-
Losartan
Correct Answer
A. LosartanExplanation
The appropriate substitute for Enalapril in this case would be Losartan. Enalapril belongs to a class of medications called ACE inhibitors, which can sometimes cause a dry cough as a side effect. Losartan, on the other hand, belongs to a class of medications called ARBs (angiotensin receptor blockers) and is less likely to cause a dry cough. Therefore, switching to Losartan would be a suitable alternative for the patient who wishes to stop taking Enalapril due to the cough.Rate this question:

What HF medication can help relieve pulmonary congestion and peripheral edema?
-
ACE inhibitors
-
ARBs
-
Diuretics
-
Direct Vasodilators
Correct Answer
A. DiureticsExplanation
Diuretics are medications that help to increase urine production and reduce fluid retention in the body. They are commonly used to treat conditions such as pulmonary congestion and peripheral edema, which are characterized by excess fluid in the lungs and swelling in the extremities. By increasing the excretion of water and salt from the body, diuretics help to alleviate these symptoms and improve overall cardiovascular function. Therefore, diuretics are an appropriate medication for relieving pulmonary congestion and peripheral edema.Rate this question:

_______ are commonly used venous dilators in CHF.
-
Resins
-
Nitrates
-
Inotropic agents
-
Statins
Correct Answer
A. NitratesExplanation
Nitrates are commonly used as venous dilators in congestive heart failure (CHF). Nitrates work by relaxing and dilating the veins, which helps to reduce the workload on the heart and improve blood flow. This can help to relieve symptoms such as shortness of breath and reduce fluid buildup in the body. Nitrates are often used in combination with other medications for the management of CHF.Rate this question:

______ reduces afterload, while _____ reduces preload.
-
Hydralazine, nitrate
-
Nitrate, hydralazine
Correct Answer
A. Hydralazine, nitrateExplanation
Hydralazine reduces afterload, which refers to the pressure or resistance that the heart has to overcome to pump blood out of the left ventricle. By reducing afterload, hydralazine helps the heart pump more efficiently. On the other hand, nitrates reduce preload, which is the amount of blood that fills the ventricles during diastole. By reducing preload, nitrates decrease the workload on the heart and improve its ability to pump blood.Rate this question:

Beta blockers improve heart's function by:
-
Inhibiting renin release
-
Decreasing heart rate
-
Blocking deleterious effects of NE on cardiac muscle fibers
-
All of the above
Correct Answer
A. All of the aboveExplanation
Beta blockers improve the heart's function by inhibiting renin release, decreasing heart rate, and blocking the deleterious effects of NE (norepinephrine) on cardiac muscle fibers. Renin is an enzyme that plays a role in regulating blood pressure, and by inhibiting its release, beta blockers help to lower blood pressure. By decreasing heart rate, beta blockers reduce the workload on the heart and improve its efficiency. NE is a neurotransmitter that can have negative effects on the heart, and beta blockers block its actions, further improving cardiac function. Therefore, all of the given options are correct explanations for how beta blockers improve heart function.Rate this question:

All of the following are positive inotropic agents, EXCEPT:
-
Beta adrenergic agonists
-
Digitalis glycosides
-
Beta adrenergic antagonists
-
Phosphodiesterase inhibitors
Correct Answer
A. Beta adrenergic antagonistsExplanation
Beta adrenergic antagonists, also known as beta blockers, are not positive inotropic agents. In fact, they have a negative inotropic effect, meaning they decrease the force of contraction of the heart. This is because beta blockers block the beta adrenergic receptors on the heart, which are responsible for the stimulatory effects of catecholamines such as epinephrine and norepinephrine. By blocking these receptors, beta blockers reduce the heart rate and contractility, making them useful in conditions such as hypertension and angina. However, they are not considered positive inotropic agents.Rate this question:

Diuretics help in heart failure by: (check all that apply)
-
Decrease preload
-
Decrease cardiac workload
-
Increase preload
-
Increase after load
-
Decrease O2 demand
Correct Answer(s)
A. Decrease preload
A. Decrease cardiac workload
A. Decrease O2 demandExplanation
Diuretics help in heart failure by decreasing preload, decreasing cardiac workload, and decreasing oxygen demand. Preload refers to the amount of blood filling the heart before it contracts, and by decreasing preload, diuretics reduce the volume of blood returning to the heart and ease the workload on the heart. Additionally, diuretics decrease the amount of fluid in the body, which reduces the workload on the heart and decreases oxygen demand. Therefore, these actions of diuretics help improve symptoms and outcomes in heart failure patients.Rate this question:

All of the following are factors predisposing a pt to digoxin toxicity, EXCEPT:
-
Hypokalemia
-
Hyperkalemia
-
Hypercalcemia
-
Hypomagnesemia
Correct Answer
A. HyperkalemiaExplanation
Digoxin toxicity is more likely to occur in patients with low potassium levels (hypokalemia), as low potassium levels enhance the effects of digoxin on the heart. Hyperkalemia, on the other hand, can actually reduce the effects of digoxin, making toxicity less likely. Hypercalcemia and hypomagnesemia can also increase the risk of digoxin toxicity by enhancing the effects of digoxin on the heart.Rate this question:

Avoid ________ in patients with HF.
Correct Answer
calcium channel blockersExplanation
Patients with heart failure (HF) should avoid calcium channel blockers. This is because calcium channel blockers can cause negative effects on the heart's contractility and can worsen HF symptoms. They can also lead to fluid retention and increase the workload on the heart, which can be detrimental for patients with HF. Therefore, it is recommended to avoid calcium channel blockers in these patients to prevent exacerbation of their condition.Rate this question:

All of the following are platelet inhibitors, EXCEPT:
-
Aspirin
-
Ticlopidine
-
Abciximab
-
Warfarin
-
Eptifibatide
Correct Answer
A. WarfarinExplanation
Warfarin is not a platelet inhibitor, but rather an anticoagulant. It works by inhibiting the synthesis of clotting factors in the liver. Platelet inhibitors, on the other hand, prevent platelets from aggregating and forming blood clots. Aspirin, Ticlopidine, Abciximab, and Eptifibatide are all examples of platelet inhibitors that work by different mechanisms to inhibit platelet function and prevent clot formation.Rate this question:

What is the most commonly used diuretic in HF?
Correct Answer
Loop DiureticsExplanation
Loop diuretics are the most commonly used diuretics in heart failure (HF) because they are highly effective in reducing fluid overload. They work by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys, leading to increased urine production and excretion of excess fluid. Loop diuretics, such as furosemide and bumetanide, are preferred in HF because they have a rapid onset of action and can provide significant symptomatic relief by reducing edema and congestion. Additionally, loop diuretics have been shown to improve outcomes in HF patients by reducing hospitalizations and mortality rates.Rate this question:

-
Epelerenone
-
Spironolactone
-
Melrinone
-
Clopidogrel
Correct Answer
A. EpelerenoneExplanation
Epelerenone is a medication that acts as a competitive antagonist of aldosterone at mineralocorticoid receptors. This means that it blocks the action of aldosterone, a hormone that promotes sodium and water retention and potassium excretion. By blocking aldosterone, epelerenone helps to reduce fluid retention and decrease blood pressure, making it an effective treatment for heart failure (HF) and left ventricular systolic dysfunction. Additionally, it has been shown to reduce mortality in patients with HF after acute myocardial infarction (MI). Therefore, the correct answer is epelerenone.Rate this question:

Neutropenia, thrombotic thrombocytopenic purpura, and aplastic anemia are all side effects of....
-
Ticlopidine
-
Warfarin
-
Heparin
-
Lovastatin
Correct Answer
A. TiclopidineExplanation
Neutropenia, thrombotic thrombocytopenic purpura, and aplastic anemia are all side effects associated with Ticlopidine. Ticlopidine is an antiplatelet medication used to prevent blood clots. However, it can lead to a decrease in the number of neutrophils (a type of white blood cell) in the body, causing neutropenia. It can also cause thrombotic thrombocytopenic purpura, a rare blood disorder characterized by blood clot formation throughout the body, leading to low platelet count and damage to organs. Additionally, Ticlopidine can result in aplastic anemia, a condition where the bone marrow fails to produce enough new blood cells.Rate this question:
