FREE DHA Pharmacist Questions and Answers

Question 1

A ___________ is sodium chromoglycate.

Accepted Answer

Mast cell stabilization

Answer

Sodium cromoglycate (or cromolyn sodium) is classified as a mast cell stabilizer. It works by preventing the release of inflammatory mediators, such as histamine and leukotrienes, from mast cells. This action helps to prevent allergic reactions and reduce inflammation, particularly in conditions like asthma and allergic rhinitis.

Question 2

The treatment for anaphylactic shock is _________.

Accepted Answer

Epinephrine

Answer

Epinephrine (adrenaline) is the first-line and most critical treatment for anaphylactic shock. It acts rapidly to reverse the severe symptoms of anaphylaxis by causing vasoconstriction, bronchodilation, and reducing swelling. Delay in administering epinephrine can be life-threatening, making it the cornerstone of emergency management for this severe allergic reaction.

Question 3

The cause of respiratory acidosis is ____________.

Accepted Answer

CO2 retention

Answer

Respiratory acidosis occurs when the lungs cannot adequately remove carbon dioxide (CO2) from the body, leading to an accumulation of CO2 in the blood. This retention of CO2 results in an increase in carbonic acid, which lowers the blood's pH, making it more acidic. Conditions like hypoventilation, COPD, or respiratory depression can cause CO2 retention.

Question 4

When treating acute gout, indomethacin is the ________ option.

Accepted Answer

First

Answer

Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that is considered a first-line treatment option for acute gout attacks. It is highly effective in reducing the pain and inflammation associated with gout due to its potent anti-inflammatory properties. Other first-line options include other NSAIDs, colchicine, and corticosteroids, but indomethacin is frequently chosen due to its efficacy.

Question 5

Which applies to the dosage of insulin.

Accepted Answer

Everything mentioned

Answer

The correct answer, 'Everything mentioned,' is right because all the options describe valid aspects of insulin dosage. An initial insulin dose for type 1 diabetes is commonly around 0.5-0.6 U/kg/day, often split with a larger morning dose. Standard NPH insulin regimens frequently use specific ratios (e.g., 1:1 or 1:2) when combined with rapid-acting insulin. Furthermore, during acute illness or stress, insulin requirements typically increase due to the release of counter-regulatory hormones, necessitating a dosage adjustment.
