15. Which one of the following agents will increase pulse pressure?
a) Adrenaline
b) Dopamine
c) Isoprenaline
d) Phenylephrine
e) Salbutamol


Answer: a) Adrenaline
The answer is A, Epinephrine has a positive ionotropic and chronotropic effect on the heart because of its beta 1-adrenergic activity. It also has an alpha-1 adrenergic activity that causes vasoconstriction in the vascular beds. These actions result in a rise in systolic blood pressure. Epinephrine also has beta 2-adrenergic activity, which causes vasodilation in skeletal muscle. Because of this latter effect, total peripheral resistance can fall, resulting in a drop in diastolic pressure, particularly at low doses of epinephrine. Pulse pressure = systolic BP – diastolic BP, so Epinephrine increases pulse pressure caused by the widening gap between systolic and diastolic BP.
Katzung has mentioned that Isoprenaline also decreases pulse pressure due to its beta 1 and beta 2 actions, however among the two adrenaline is slightly more likely to increase pulse pressure because it can further increase systolic BP via its alpha-1 agonist effect.

21. Exaggerated IgE mediated response causes Atopic diseases e.g asthma rhinitis, are what type of hypersensitivity?
A. Type I
B. Type II
C. Type III
D. Type IV

Answer: A. Type I
Hypersensitivity: exaggerated immune response that is harmful to the individual.
Type I hypersensitivity: also known as immediate hypersensitivity or allergy and include atopy e.g allergic rhinitis or hay fever, food allergies, eczema, Asthma and anaphylaxis.
Caused by elevated IgE production, IgE being bound by Fc epsilon receptor on the surface of mast cells this IgE bound to mast cells causes release of others mediators e.g histamine.
