Questions and Answers
  • 1. 

    Which of the following are beta 1 adrenergics

    • A.

      Dobutamine

    • B.

      Dopamine

    • C.

      Epinephrine

    • D.

      Norepinephrine

    Correct Answer(s)
    A. Dobutamine
    B. Dopamine
    Explanation
    Dobutamine and dopamine are both beta 1 adrenergics because they selectively stimulate the beta 1 adrenergic receptors in the body. These receptors are found primarily in the heart and play a role in increasing heart rate and contractility. Epinephrine and norepinephrine, on the other hand, are non-selective adrenergic agonists that stimulate both beta 1 and beta 2 adrenergic receptors.

    Which of the following are non selective adrenergics (both alpha and beta)

    • A.

      Epinephrine

    • B.

      Norepinephrine

    • C.

      Dopamine

    • D.

      Midodrine

    Correct Answer(s)
    A. Epinephrine
    B. Norepinephrine
    Explanation
    Epinephrine and norepinephrine are both non-selective adrenergic agonists that activate both alpha and beta adrenergic receptors. They are naturally occurring catecholamines and play a crucial role in the body's response to stress. Epinephrine is commonly used in emergency situations to treat severe allergic reactions, cardiac arrest, and asthma attacks. Norepinephrine is primarily involved in regulating blood pressure and is used in the treatment of hypotension. Dopamine, on the other hand, primarily acts on dopamine receptors and has limited activity on alpha and beta receptors. Midodrine is a selective alpha-1 adrenergic agonist used to treat orthostatic hypotension.

    Which of the following are alpha adrenergics?

    • A.

      Midodrine

    • B.

      Phenylephrine

    • C.

      Epinephrine

    • D.

      Dobutamine

    Correct Answer(s)
    A. Midodrine
    B. Phenylephrine
    Explanation
    Midodrine and phenylephrine are alpha adrenergics because they act on alpha-adrenergic receptors in the body. These receptors are found in various tissues and organs, including blood vessels. Activation of alpha adrenergic receptors causes vasoconstriction, which leads to an increase in blood pressure. Midodrine and phenylephrine are commonly used to treat conditions such as low blood pressure and orthostatic hypotension. Epinephrine and dobutamine, on the other hand, are not alpha adrenergics but rather beta adrenergics, as they primarily act on beta-adrenergic receptors.

  • 4. 

    Which of the following are alpha blockers

    • A.

      Phentolamine

    • B.

      Tamsulosin

    • C.

      Atenolol

    • D.

      Carvedilol

    Correct Answer(s)
    A. Phentolamine
    B. Tamsulosin
    Explanation
    Phentolamine and tamsulosin are both alpha blockers. Alpha blockers work by blocking the alpha receptors in certain muscles and blood vessels, causing them to relax. This relaxation helps to lower blood pressure and improve blood flow. Atenolol and carvedilol, on the other hand, are beta blockers, which work by blocking the beta receptors in the heart and blood vessels, reducing the effects of stress hormones like adrenaline. Therefore, the correct answer is phentolamine and tamsulosin.

    • A.

      Carvedilol

    • B.

      Atenolol

    • C.

      Propranalol

    • D.

      Labetalol

    • E.

      Sotalol

    • F.

      Metoprolol

    Correct Answer(s)
    A. Carvedilol
    C. Propranalol
    D. Labetalol
    E. Sotalol
    Explanation
    Carvedilol, propranolol, labetalol, and sotalol are nonselective beta blockers because they block both beta-1 and beta-2 receptors. Atenolol and metoprolol, on the other hand, are selective beta blockers as they primarily target beta-1 receptors.

    Rate this question:

  • 6. 

    Which of the following are cardioselective beta blockers

    • A.

      Atenolol

    • B.

      Esmolol

    • C.

      Metoprolol

    • D.

      Labetalol

    • E.

      Propranolol

    Correct Answer(s)
    A. Atenolol
    B. Esmolol
    C. Metoprolol
    Explanation
    Atenolol, esmolol, and metoprolol are cardioselective beta blockers because they primarily target and block the beta-1 receptors in the heart. This selectivity allows them to reduce heart rate and blood pressure without significantly affecting the beta-2 receptors in the lungs and blood vessels, minimizing the risk of bronchoconstriction and peripheral vasoconstriction. Labetalol and propranolol, on the other hand, are non-selective beta blockers that block both beta-1 and beta-2 receptors, leading to a wider range of effects throughout the body.

    • C.

      Structurally similar to dopamine

    • D.

      Speeds up HR

    • E.

      Increases cardiac output and stroke volume

    • F.

      Bronchodilation

    Correct Answer(s)
    A. Beta 1 adrenergic
    C. Structurally similar to dopamine
    D. Speeds up HR
    E. Increases cardiac output and stroke volume
    Explanation
    Dobutamine is a medication that has multiple effects on the body. It is a beta 1 adrenergic agonist, meaning it specifically targets and activates beta 1 adrenergic receptors. It is also structurally similar to dopamine, another neurotransmitter in the body. Dobutamine speeds up the heart rate, which is known as tachycardia. Additionally, it increases cardiac output and stroke volume, which means it improves the ability of the heart to pump blood. However, it does not have bronchodilatory effects, so it does not cause the relaxation of bronchial smooth muscles.

    A. Beta 1 adrenergic
    B. Different receptor activity depending on dosage
    C. Naturally occurring catecholamine
    D. Speeds up HR
    E. Helps treat shock at certain dosages
    Explanation
    Dopamine is a naturally occurring catecholamine that acts on beta 1 adrenergic receptors. Its receptor activity can vary depending on the dosage, meaning that it can have different effects at different doses. Dopamine speeds up heart rate (HR) and can be used to treat shock at certain dosages. It does not have a direct effect on bronchodilation.

    • E.

      Shock related symptoms

    Correct Answer(s)
    B. Nonselective adrenergic
    C. Used to treat anaphylactic shock
    D. Used to treat asthma
    Explanation
    Epinephrine is a nonselective adrenergic drug, meaning it acts on both beta 1 and beta 2 adrenergic receptors. It is used to treat anaphylactic shock, a severe allergic reaction that can cause life-threatening symptoms. Epinephrine is also used to treat asthma, as it helps to relax the muscles in the airways and improve breathing. Therefore, the correct answer includes "nonselective adrenergic," "used to treat anaphylactic shock," and "used to treat asthma."

    Correct Answer(s)
    A. Alpha 1 adrenergic
    C. Used primarily for symptomatic orthostatic hypotension
    D. Last dose should not be given after 6 pm
    Explanation
    Midodrine is a medication that works as an alpha 1 adrenergic agonist, which means it stimulates the alpha 1 adrenergic receptors. It is primarily used for symptomatic orthostatic hypotension, a condition where a person's blood pressure drops significantly when they stand up. It helps raise blood pressure and improve symptoms in these patients. Additionally, it is recommended that the last dose of midodrine should not be given after 6 pm to prevent any potential sleep disturbances or difficulties falling asleep.

    Correct Answer(s)
    A. Directly metabolized to dopamine
    B. Non-selective adrenergic
    C. Primarily used in the treatment of hypotension and shock
    Explanation
    Norepinephrine is a neurotransmitter and hormone that is directly metabolized to dopamine in the body. It is also a non-selective adrenergic agent, meaning it activates both alpha and beta adrenergic receptors. Norepinephrine is primarily used in the treatment of hypotension and shock, as it increases blood pressure by constricting blood vessels. However, it cannot be given as a large bolus because it can cause severe vasoconstriction and tissue damage. Additionally, it cannot be administered topically as an ophthalmic drug.

    Correct Answer(s)
    A. Alpha adrenergic
    C. Short term treatment to raise blood pressure
    D. Can be applied topically as an opthalmic drug
    E. Vasoconstriction in anesthesia
    Explanation
    Phenylephrine is an alpha adrenergic drug, meaning it acts on alpha adrenergic receptors in the body. It is used for short-term treatment to raise blood pressure, as it causes vasoconstriction, narrowing the blood vessels and increasing blood pressure. It can also be applied topically as an ophthalmic drug, as it causes constriction of blood vessels in the eye, reducing redness and swelling. Additionally, phenylephrine is used for vasoconstriction in anesthesia, helping to control bleeding during surgical procedures.
