Pharmacokinetics

Step 1: Understanding the half-life of insulin.
The half-life of insulin is relatively short compared to other hormones. It is typically around 5-6 minutes in the bloodstream after administration.
Step 2: Analyzing the options.
(1) : Incorrect, insulin's half-life is longer than 1 minute.
(2) 5-6 mins: Correct — The half-life of insulin is approximately 5-6 minutes.
(3) 30-40 mins: Incorrect, insulin's half-life is much shorter.
(4) 1-2 hrs: Incorrect, this is far longer than insulin's actual half-life.
Step 3: Conclusion.
The correct half-life of insulin is (2) 5-6 mins.

Step 1: Understanding iron deficiency anemia in pregnancy.
Iron deficiency anemia during pregnancy is common and typically treated with iron supplements, such as ferrous sulphate, which helps replenish iron stores and supports healthy fetal development.
Step 2: Analyzing the options.
(1) Ferrous sulphate: Correct — Ferrous sulphate is the most commonly used treatment for iron deficiency anemia during pregnancy.
(2) Iron-dextrin tablet: Incorrect, iron-dextrin is a type of iron supplement, but ferrous sulphate is typically preferred.
(3) Folic acid: Incorrect, while folic acid is important for pregnancy, it does not treat iron deficiency anemia.
(4) Iron-dextrin injection: Incorrect, iron injections are typically used when oral supplements are not effective or well-tolerated.
Step 3: Conclusion.
The correct treatment for iron deficiency anemia during pregnancy is (1) Ferrous sulphate.
