    Which one of the following antihypertensive drugs can precipitate a hypertensive crisis following abrupt cessation of therapy?

    • Clonidine

    • Diltiazem

    • Enalapril

    • Losartan

    Correct Answer
    A. Clonidine
    Explanation
    Clonidine is an antihypertensive drug that works by reducing blood pressure. However, if clonidine is abruptly stopped, it can cause a sudden increase in blood pressure, leading to a hypertensive crisis. This is because clonidine acts on certain receptors in the brain that regulate blood pressure, and abrupt cessation can cause these receptors to become overactive. Therefore, clonidine is the correct answer as it can precipitate a hypertensive crisis if therapy is abruptly discontinued.

    An 8 yo has a fever and muscles aches from viral infection?

    • Acetaminophen

    • Aspirin

    • Celecoxib

    • Codeine

    Correct Answer
    A. Acetaminophen
    Explanation
    Acetaminophen is the correct answer because it is a commonly used over-the-counter medication for reducing fever and relieving mild to moderate pain. It is safe and effective for children, including an 8-year-old, when used as directed. Aspirin is not recommended for children due to the risk of Reye's syndrome. Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that is typically used for arthritis and not for treating viral infections. Codeine is an opioid medication that is generally not recommended for children due to safety concerns.

    Digoxin has a profound effect on myocyte intracellular concentrations of sodium, potassium and calcium.  These effects are caused by digoxin inhibiting:

    • Ca-ATPase of the sarcoplasmic reticulum

    • Sodium ATpase of the myocyte membrane

    • Cardiac phosphodiesterase

    • Cardiac beta receptors

    • Juxtoglomerular renin release

    Correct Answer
    A. Sodium ATpase of the myocyte membrane
    Explanation
    Digoxin inhibits the sodium ATPase of the myocyte membrane. This inhibition leads to an increase in intracellular sodium levels, which subsequently affects the function of other ion transporters, including the sodium-calcium exchanger. The higher intracellular sodium concentration reduces the activity of the exchanger, resulting in an increase in intracellular calcium levels. This increase in calcium enhances myocardial contractility, making digoxin an effective treatment for heart failure.

    Rate this question:

  • 7. 

    Which of the following is associated with digoxin in patients wtih HF?

    • Improvement of symptoms in a patient with CHF

    • Increase myocardial contractility

    • All of these

    • Slowing down AV conduction

    • Inhibition of sympathetic activity

    Correct Answer
    A. All of these
    Explanation
    Digoxin is a medication commonly used in the treatment of heart failure (HF). It works by increasing myocardial contractility, which improves the pumping ability of the heart and helps alleviate symptoms of HF. Additionally, digoxin can slow down atrioventricular (AV) conduction, which can be beneficial in certain cases. Moreover, it can also inhibit sympathetic activity, further contributing to the improvement of symptoms in patients with congestive heart failure (CHF). Therefore, all of these options are associated with digoxin in patients with HF.

    A 56 yo has chest pain following any sustained exercise.  He is dianosed with atherosclerotic angina.  He is prescribed sublingual nitro  - which is likely to be experienced?

    • Braydcardia

    • Sexual dysfunction

    • Throbbing HA

    • Hypertension

    Correct Answer
    A. Throbbing HA
    Explanation
    Atherosclerotic angina is caused by the narrowing of coronary arteries due to the buildup of plaque. Sublingual nitroglycerin is a medication commonly used to treat angina. It works by relaxing and widening the blood vessels, improving blood flow to the heart. One of the common side effects of nitroglycerin is a throbbing headache (throbbing HA). Therefore, it is likely that the patient may experience throbbing headaches as a side effect of taking sublingual nitro for their atherosclerotic angina.

    A 58 yo is being treated for chronic suppression of vent arrhytmia.  After 2 months of therapy she complains about feeling tired all the time.  Exam reveals resting HR of 10 bpm lower than previous rate.  Her skin is cool and clammy.  Lab test results indicate low thyroxin and elevated TSh.  Which of the following is the likely cause of these symptoms?

    • Amiodarone

    • Procainamide

    • Propranolol

    • Quinidine

    • Verapamil

    Correct Answer
    A. Amiodarone
    Explanation
    The likely cause of the symptoms described (feeling tired, lower heart rate, cool and clammy skin, low thyroxin, and elevated TSH) is amiodarone. Amiodarone is a medication commonly used to treat arrhythmias, but it can also cause hypothyroidism as a side effect. Hypothyroidism can lead to fatigue, bradycardia (lower heart rate), and cool and clammy skin. The lab test results of low thyroxin and elevated TSH further support the diagnosis of amiodarone-induced hypothyroidism.

    • Exenatide

    • Glyburide

    • Nateglinide

    • Rosliglitazone

    Correct Answer
    A. Rosliglitazone
    Explanation
    Rosiglitazone would be a poor choice for the 64-year-old woman with a history of type 2 diabetes and heart failure (HF). Rosiglitazone belongs to the thiazolidinedione class of antidiabetic medications, which have been associated with an increased risk of cardiovascular events and heart failure. Therefore, prescribing rosiglitazone to a patient with HF would not be recommended due to the potential harm it may cause to the cardiovascular system.

    IN which of the following would aspirin be contraindicated?

    • Myalgia

    • Fever

    • Peptic ulcer

    • RA

    Correct Answer
    A. Peptic ulcer
    Explanation
    Aspirin would be contraindicated in individuals with peptic ulcer. This is because aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the stomach lining and increase the risk of bleeding or ulceration in individuals with peptic ulcers. Therefore, it is recommended to avoid aspirin in such cases and consider alternative pain relievers that are safer for individuals with peptic ulcers.

    What is contraindicated in patient with hyperkalemia?

    • Chlorotiazide

    • Acetazolomide

    • Spironolactone

    Correct Answer
    A. Spironolactone
    Explanation
    Spironolactone is contraindicated in patients with hyperkalemia because it is a potassium-sparing diuretic. This means that it helps the body retain potassium instead of excreting it through urine. In patients with hyperkalemia, there is already an excess of potassium in the blood, and taking spironolactone can further increase potassium levels, potentially leading to serious complications such as cardiac arrhythmias. Therefore, it is important to avoid spironolactone in patients with hyperkalemia to prevent worsening of their condition.

    Which of the following statements concerning H1 antihistamines is correct?

    • Second gen are relatively free of adverse effects

    • H1 antihistamines can be used in the treatment of acute anaphylaxis

    Correct Answer
    A. Second gen are relatively free of adverse effects
    Explanation
    The correct answer is "second gen are relatively free of adverse effects". Second generation H1 antihistamines, such as loratadine and cetirizine, are known to have fewer adverse effects compared to first generation antihistamines. They have a reduced sedative effect and are less likely to cause drowsiness, dizziness, or impair cognitive function. This makes them a preferred choice for long-term use in the treatment of allergies. However, it is important to note that H1 antihistamines, including second generation ones, are not typically used in the treatment of acute anaphylaxis, as this requires more immediate and specific interventions such as epinephrine administration.

    Which one of the following would impair the ability to drive an automobile?

    • Diphenhydramine

    • Ergotamine

    • Fexofenadine

    • Ranitidine

    Correct Answer
    A. Diphenhydramine
    Explanation
    Diphenhydramine is an antihistamine that can cause drowsiness and impair cognitive and motor skills, which are essential for safe driving. It is a common ingredient in many over-the-counter sleep aids and allergy medications. Impairment of these abilities can increase the risk of accidents while operating a vehicle. Ergotamine, fexofenadine, and ranitidine do not typically have sedative effects and are less likely to impair driving ability.

    Compensatory increases in heart rate and renin release that occur in heart failure may be alleviated by which of the following drugs?

    • Metoprolol

    • Dobutamine

    • Enalapril

    • Milrinone

    • Digoxin

    Correct Answer
    A. Metoprolol
    Explanation
    Metoprolol is a beta-blocker that can alleviate compensatory increases in heart rate and renin release that occur in heart failure. It works by blocking the effects of adrenaline on the heart, reducing heart rate and blood pressure. This helps to improve the efficiency of the heart and reduce the workload on the heart, ultimately alleviating the symptoms of heart failure. Dobutamine, enalapril, milrinone, and digoxin are not specifically indicated for alleviating compensatory increases in heart rate and renin release in heart failure.

    • Furosemide

    • Chlorthalidone

    Correct Answer
    A. Spironolactone
    Explanation
    Spironolactone is prescribed to control ascites and edema in a patient with hepatic cirrhosis. This medication is a potassium-sparing diuretic that works by blocking the effects of aldosterone, a hormone that can cause fluid retention. By blocking aldosterone, spironolactone helps to reduce fluid buildup in the body and control the symptoms of ascites and edema. Hydrochlorothiazide, acetazolamide, furosemide, and chlorthalidone are diuretics that may be used to treat other conditions but are not typically prescribed for ascites and edema in patients with hepatic cirrhosis.

    A 54 yo with prosthetic valve has black and tarry stools - PE unremarkable except for subconunctival hemorrhages and bleeding gums.  Stools tested positive for heme.  Patient has been on oral warfarin since valve replacement one year ago.  PT elevated.  Which of the following therapies should be given?

    • Intravenous vitamin K

    • Transfusion of FFP

    • IV protamine sulfate

    • Immediate withdrawal of warfarin treatment

    Correct Answer
    A. Transfusion of FFP
    Explanation
    The patient's presentation of black and tarry stools, subconjunctival hemorrhages, and bleeding gums suggests gastrointestinal bleeding, which can be a complication of anticoagulant therapy with warfarin. The positive test for heme in the stools further supports this suspicion. The elevated PT indicates that the patient's blood is not clotting properly. Transfusion of fresh frozen plasma (FFP) is the appropriate therapy in this situation as it contains clotting factors that can help restore normal clotting function and control the bleeding. Intravenous vitamin K is not the correct choice as it takes longer to take effect compared to FFP. IV protamine sulfate is used to reverse the anticoagulant effects of heparin, not warfarin. Immediate withdrawal of warfarin treatment may worsen the bleeding and is not recommended.

    A 57 yo man is being treated for an atrial arrhythmia.  He complains of HA, dizziness, and tinnitus.  Which one of the following antiarrhtymics is the most likely cause?

    • Amiodarone

    • Procainamide

    • Propranolol

    • Quinidine

    • Verapamil

    Correct Answer
    A. Quinidine
    Explanation
    Quinidine is the most likely cause of the symptoms described in the question. Quinidine is an antiarrhythmic medication that can cause side effects such as headache (HA), dizziness, and tinnitus. These symptoms are consistent with the patient's complaint. Amiodarone, procainamide, propranolol, and verapamil are also antiarrhythmic medications, but they are not known to commonly cause these specific symptoms.

    A 48 yo hypertensive patient has been successfully treated with a thiazide diuretic for the last 5 years.  Over the last 3 months, his diastolic pressure has steadily increased and he has started on an additional antihypertensive med.  He has severael instances of being unable to achieve an erection and is no longer able to complete three sets of tennis.  Which of the following is the likely cause?

    • Captopril

    • Losartan

    • Minoxidil

    • Metoprolol

    Correct Answer
    A. Metoprolol
    Explanation
    Metoprolol is the likely cause for the patient's inability to achieve an erection and decreased exercise capacity. Metoprolol is a beta-blocker commonly used to treat hypertension. One of its side effects is sexual dysfunction, including difficulty achieving and maintaining an erection. Additionally, beta-blockers can cause fatigue and decreased exercise tolerance, which could explain the patient's inability to complete three sets of tennis.

    Which one of the following is true for COx 2?

    • COX 2 have greater analgesic effects that tranditional NSAIDS

    • COX 2 decrease platelet function

    • COX 2 do not affect the kidney

    • COX 2 show antiinflammatory effects similar to traditional NSAIDS

    Correct Answer
    A. COX 2 show antiinflammatory effects similar to traditional NSAIDS
    Explanation
    COX 2 show antiinflammatory effects similar to traditional NSAIDs. This means that COX 2 inhibitors, like traditional NSAIDs, can help reduce inflammation in the body. This is an important property for medications used to treat conditions such as arthritis, where inflammation is a major component of the disease. COX 2 inhibitors specifically target the COX 2 enzyme, which is responsible for producing inflammatory molecules called prostaglandins. By inhibiting COX 2, these medications can help reduce inflammation and alleviate symptoms associated with inflammatory conditions.

    Which of the following can precipitate a hypertensive crisis following abrupt cessation of therapy?

    • Losartan

    • Enalapril

    • HCTZ

    • Clonidine

    Correct Answer
    A. Clonidine
    Explanation
    Clonidine is an alpha-2 adrenergic agonist commonly used to treat hypertension. Abrupt cessation of clonidine can cause a rebound effect, leading to a hypertensive crisis. This occurs because clonidine suppresses the release of norepinephrine, a neurotransmitter that constricts blood vessels and increases blood pressure. When clonidine is suddenly stopped, there is an unopposed surge in norepinephrine release, causing a sudden increase in blood pressure. Therefore, clonidine is the correct answer as it can precipitate a hypertensive crisis following abrupt cessation of therapy.

    Which one of hte following drugs causes a decrease in liver triacylglycerol by limitng available free fatty acids needed as buildig blocks for this pathway?

    • Cholestyramine

    • Fenofibrate

    • Niacin

    • Lovastatin

    Correct Answer
    A. Niacin
    Explanation
    Niacin is the correct answer because it causes a decrease in liver triacylglycerol by limiting available free fatty acids needed as building blocks for this pathway. Niacin, also known as vitamin B3, inhibits the breakdown of stored fats in adipose tissue, leading to a decrease in the release of free fatty acids into the bloodstream. This reduction in free fatty acids limits the availability of substrates for the synthesis of triacylglycerol in the liver, ultimately resulting in a decrease in liver triacylglycerol levels. Cholestyramine, fenofibrate, and lovastatin do not directly affect the availability of free fatty acids and therefore do not cause a decrease in liver triacylglycerol in the same manner as niacin.

    Which predisposes the most to hyperkalemia?

    • Enalapril plus HCT

    • Enalaprils in patients with poor renal functio

    • Enalapril plus furosemide

    • Furosemide in poor renal function

    Correct Answer
    A. Enalaprils in patients with poor renal functio
    Explanation
    Patients with poor renal function are more likely to develop hyperkalemia when taking enalaprils. Enalaprils are a type of medication known as ACE inhibitors, which can increase the levels of potassium in the blood. Poor renal function can impair the kidneys' ability to excrete excess potassium, leading to its accumulation in the bloodstream. This combination of enalaprils and poor renal function increases the risk of hyperkalemia, a condition characterized by high levels of potassium in the blood.

    Suppression of arrhytmias resulting from a reentry focus is most likely to occur if the drug:

    • Has vagomimetic effects on the AV node

    • Is a beta blocker

    • Converts a unidirectional block to a bidirectional block

    • Slows conduction through the atria

    • Has atropine like effects on the AV node

    Correct Answer
    A. Converts a unidirectional block to a bidirectional block
    Explanation
    When a reentry focus is present, the arrhythmias occur due to the reentry circuit. By converting a unidirectional block (where the electrical signal can only pass through in one direction) to a bidirectional block (where the electrical signal can pass through in both directions), the drug can disrupt the reentry circuit and suppress the arrhythmias. This allows the normal electrical conduction to resume and prevents the reentry circuit from perpetuating the arrhythmias.

    A 60 yo man has a DVT and was started with a bolus of heparin.  One hour later he was bleeding profusely from IV site.  The heparin was suspended and bleeding continued.  Protamine sulfate was administered IV and the bleeding resolved - The protamine

    • Degrades the heparin

    • Inactivates the antithrombin

    • Activates the coagulation cascade

    • Ionically combines with heparin

    Correct Answer
    A. Ionically combines with heparin
    Explanation
    Protamine sulfate ionically combines with heparin. Protamine is a positively charged molecule that binds to the negatively charged heparin, forming a stable complex. This complex helps to neutralize the anticoagulant effects of heparin and prevent further bleeding.

    Which would be the initial treatment choice to manage the hypertension in an AA women with a past medical history of gout and severe hypokalemia?

    • HCTZ

    • Spironolactone

    • Valsartan

    • Atenolol

    • Enalapril

    Correct Answer
    A. Spironolactone
    Explanation
    Spironolactone would be the initial treatment choice to manage hypertension in an AA woman with a past medical history of gout and severe hypokalemia. Spironolactone is a potassium-sparing diuretic that not only helps to lower blood pressure but also helps to prevent hypokalemia. This is especially important in this case since the patient already has a history of severe hypokalemia. Additionally, spironolactone is a good choice for patients with gout as it does not increase uric acid levels like other diuretics such as HCTZ.
