Questions and Answers

1.

What happens when you stimulate beta 1 receptors?
- A.
  
  Bronchodilation
- B.
  
  Urinary retention
- C.
  
  Increase HR, increase AV conduction velocity & increase force of contraction
- D.
  
  Stimulation decreases further norepinephrine release
Correct Answer
C. Increase HR, increase AV conduction velocity & increase force of contraction

Explanation
Stimulating beta 1 receptors leads to an increase in heart rate (HR), an increase in atrioventricular (AV) conduction velocity, and an increase in the force of contraction. This means that when beta 1 receptors are stimulated, the heart beats faster, the electrical signals between the atria and ventricles are conducted more quickly, and the strength of the heart's contractions is enhanced. This response is important for increasing cardiac output and maintaining adequate blood flow throughout the body.

What happens when you stimulate alpha 2 receptors?
- A.
  
  Decreases further norepinephrine release
- B.
  
  Urinary retention, pupil dilation, vasoconstriction in vessels of skin, mucous membranes & most organs
- C.
  
  Increase HR, AV velocity conduction, and force of contraction
- D.
  
  Relaxation of uterine muscles
Correct Answer
A. Decreases further norepinepHrine release

Explanation
Stimulating alpha 2 receptors leads to a decrease in the release of norepinephrine. This means that less norepinephrine is released into the body, which can have various effects. These effects include urinary retention, pupil dilation, vasoconstriction in vessels of the skin, mucous membranes, and most organs. On the other hand, stimulating alpha 2 receptors does not increase heart rate, AV velocity conduction, or force of contraction. Additionally, it does not cause relaxation of uterine muscles.

What happens when you stimulate the beta 2 receptors?
- A.
  
  Decrease further norepinephrine release
- B.
  
  Increase liver sugar production, vasodilation in vessels of skeletal muscles, lungs, & heart, relaxation of uterine muscles
- C.
  
  Urinary retention
- D.
  
  Increase HR, AV conduction velocity & force of contraction
Correct Answer
B. Increase liver sugar production, vasodilation in vessels of skeletal muscles, lungs, & heart, relaxation of uterine muscles

Explanation
Stimulating the beta 2 receptors leads to an increase in liver sugar production, vasodilation in vessels of skeletal muscles, lungs, and heart, as well as relaxation of uterine muscles. This means that when these receptors are stimulated, the body increases the production of sugar in the liver, which can provide a quick source of energy. Additionally, the blood vessels in skeletal muscles, lungs, and heart widen, allowing for increased blood flow and oxygen delivery to these areas. Finally, the muscles of the uterus relax, which can be beneficial during childbirth.

What happens when you stimulate the alpha 1 receptors?
- A.
  
  Increase in HR, AV conduction velocity & force of contraction
- B.
  
  Bronchodilation
- C.
  
  Pupil dilation, urinary retention
- D.
  
  Decrease further release of norepinephrine
Correct Answer
C. Pupil dilation, urinary retention

Explanation
Stimulation of alpha 1 receptors causes pupil dilation and urinary retention. Alpha 1 receptors are located in the smooth muscle of the iris and the urinary bladder. Activation of these receptors leads to contraction of the radial muscle of the iris, causing pupil dilation. It also causes contraction of the smooth muscle in the urinary bladder, leading to urinary retention.

Adrenergic Agonists may cause reflex bradycardia with increased blood pressure.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Adrenergic agonists are drugs that stimulate the adrenergic receptors in the sympathetic nervous system, leading to an increase in heart rate and blood pressure. However, this increase in blood pressure can trigger a reflex response in the body, causing the heart rate to slow down, resulting in bradycardia. Therefore, it is true that adrenergic agonists may cause reflex bradycardia with increased blood pressure.

- B.
  
  Alpha 2 adrenergic agonist
- C.
  
  Cardioselective beta 1 blocker
- D.
  
  Non-selective beta blocker
Correct Answer
A. AlpHa 1 blocker

Explanation
Prazosin is classified as an alpha 1 blocker. Alpha 1 blockers work by blocking the alpha 1 adrenergic receptors, which are found in smooth muscle tissues of blood vessels. By blocking these receptors, prazosin causes the blood vessels to relax and dilate, leading to a decrease in blood pressure. This class of drugs is commonly used to treat conditions such as hypertension and benign prostatic hyperplasia.

Rate this question:
14.

Which are the key drugs for managing hypertension?
- A.
  
  ARB's
- B.
  
  Beta Blockers
- C.
  
  ACE-Inhibitors
Correct Answer
C. ACE-Inhibitors

Explanation
ACE-Inhibitors are key drugs for managing hypertension because they work by blocking the action of an enzyme called angiotensin-converting enzyme (ACE), which is responsible for the production of a hormone called angiotensin II. Angiotensin II causes blood vessels to constrict and promotes the release of another hormone called aldosterone, which increases blood pressure. By inhibiting ACE, ACE-Inhibitors help to relax and widen blood vessels, reducing blood pressure and improving blood flow. They are commonly prescribed as a first-line treatment for hypertension and have been shown to be effective in reducing cardiovascular events and mortality rates in patients with hypertension.

Rate this question:
15.

Which CCB does not have negative inotropic effects?
- A.
  
  Amlodipine
- B.
  
  Diltiazem
- C.
  
  Felodipine
Correct Answer
A. Amlodipine

Explanation
Amlodipine is a calcium channel blocker (CCB) that does not have negative inotropic effects. Negative inotropic effects refer to the ability of a drug to decrease the strength of the heart's contractions. Amlodipine works by blocking calcium channels in the smooth muscle cells of blood vessels, leading to vasodilation and reduced peripheral resistance. It does not significantly affect cardiac contractility, making it a suitable choice for patients with heart conditions who need blood pressure control without compromising cardiac function. Diltiazem and felodipine, on the other hand, are CCBs that can have negative inotropic effects.

Spironolactone can cause hypokalemia.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Spironolactone is a medication commonly used to treat conditions such as high blood pressure and heart failure. It is a potassium-sparing diuretic, meaning it helps the body retain potassium instead of excreting it through urine. Therefore, it does not cause hypokalemia, which is a condition characterized by low levels of potassium in the blood. Hence, the statement that Spironolactone can cause hypokalemia is false.

Rate this question:
20.

Furosemide is a loop diuretic.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Furosemide is indeed a loop diuretic. Loop diuretics, such as furosemide, work by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys. This leads to increased excretion of water and electrolytes, resulting in diuresis. Furosemide is commonly used to treat conditions such as edema and hypertension.

Rate this question:
21.

Which drugs can cause dehydration, hypokalemia & electrolyte imbalance?
- A.
  
  Furosemide & spironolactone
- B.
  
  Furosemide & hydrochlorothiazide
- C.
  
  Spironolactone & amiloride
- D.
  
  Verapamil & hydrochlorothiazide
Correct Answer
B. Furosemide & hydrochlorothiazide

Explanation
Furosemide and hydrochlorothiazide are both diuretic medications that increase urine production, leading to fluid loss from the body. This fluid loss can result in dehydration. Additionally, both drugs can cause imbalances in electrolytes such as potassium, leading to hypokalemia. Therefore, furosemide and hydrochlorothiazide are the drugs that can cause dehydration, hypokalemia, and electrolyte imbalance.

Rate this question:
22.

An adverse effect of loop diuretics is hyperuricemia (gout).
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Loop diuretics, such as furosemide, can lead to an increase in uric acid levels in the blood, which can result in hyperuricemia or gout. This occurs because loop diuretics inhibit the reabsorption of sodium and chloride in the loop of Henle, leading to increased excretion of uric acid. As a result, uric acid levels can rise, potentially causing gout attacks in individuals who are predisposed to the condition. Therefore, the statement "An adverse effect of loop diuretics is hyperuricemia (gout)" is true.

NSAIDS can worsen CHF
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
NSAIDs (nonsteroidal anti-inflammatory drugs) can worsen CHF (congestive heart failure) because they can cause fluid retention and decrease the effectiveness of diuretics, which are commonly used to manage CHF symptoms. Additionally, NSAIDs can also increase blood pressure and put extra strain on the heart, leading to further deterioration of heart function in individuals with CHF. Therefore, it is important for individuals with CHF to avoid or use NSAIDs cautiously under the guidance of a healthcare professional.

Thiazide and loop diuretics can be used together.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Thiazide and loop diuretics can be used together because they have different mechanisms of action and target different parts of the kidney. Thiazide diuretics work on the distal convoluted tubule to inhibit sodium reabsorption, while loop diuretics work on the ascending loop of Henle to inhibit sodium and water reabsorption. Combining these two types of diuretics can lead to a more potent diuretic effect and can be beneficial in certain clinical situations, such as in patients with resistant edema or congestive heart failure.

Which drug can cause ototoxicity?
- A.
  
  HCTZ
- B.
  
  Furosemide
- C.
  
  Spironolactone
- D.
  
  Amiloride
Correct Answer
B. Furosemide

Explanation
Furosemide is a loop diuretic commonly used to treat conditions such as edema and hypertension. One of the potential side effects of furosemide is ototoxicity, which refers to damage to the inner ear and resulting hearing loss or balance problems. Ototoxicity can occur due to the drug's impact on the delicate structures of the inner ear, specifically the hair cells responsible for transmitting sound signals to the brain. Therefore, furosemide is known to have the potential to cause ototoxicity.

Which drugs should be used in chronic exertional angina?
- A.
  
  CCB
- B.
  
  Beta blockers
- C.
  
  Nitrates
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Chronic exertional angina is a condition characterized by chest pain or discomfort that occurs during physical activity or exertion. The goal of treatment is to relieve symptoms and reduce the frequency and severity of angina episodes. CCBs (calcium channel blockers) help relax and widen the blood vessels, reducing the workload on the heart. Beta blockers help decrease the heart rate and blood pressure, reducing the demand for oxygen by the heart. Nitrates help dilate the blood vessels, improving blood flow to the heart. Therefore, all of the mentioned drugs (CCBs, beta blockers, and nitrates) can be used in the treatment of chronic exertional angina.

Patients with chronic exertional angina should be told to stop smoking, exercise & avoid excessive alcohol use.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Patients with chronic exertional angina should be told to stop smoking, exercise, and avoid excessive alcohol use because these lifestyle modifications can help improve their condition. Smoking can constrict blood vessels and decrease oxygen supply to the heart, while exercise can help strengthen the heart and improve blood flow. Excessive alcohol use can also have negative effects on the heart and worsen symptoms. Therefore, it is important for patients with chronic exertional angina to make these changes to reduce the risk of complications and improve their overall health.

Concurrent use of fibrates and statins increases the risk of muscle myopathy.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The concurrent use of fibrates and statins increases the risk of muscle myopathy. This is because both fibrates and statins can cause muscle-related side effects, such as muscle pain, weakness, and inflammation. When used together, these medications can potentiate each other's effects and further increase the risk of muscle myopathy. Therefore, it is important to monitor patients closely and consider alternative treatment options if necessary.

325 mg of ASA is a cardiac dose of aspirin.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
A cardiac dose of aspirin refers to the specific dosage of aspirin that is commonly prescribed for individuals with heart conditions. It is typically recommended for its blood-thinning properties, which can help prevent blood clots and reduce the risk of heart attacks or strokes. In this case, 325 mg of ASA (acetylsalicylic acid), which is the active ingredient in aspirin, is considered a cardiac dose. Therefore, the statement is true.
