**Question:** DMPA-True: a) Failure @ 0.3/100 WY b) 150 mg/3 monthly delivered c) Weight gain d) Glucose intolerance occurs e) Anemia improves
**Core Concept:** Depot Medroxyprogesterone Acetate (DMPA) is a long-acting progestin-only contraceptive hormone used for contraception and treatment of heavy menstrual bleeding. It is administered as an intramuscular injection. DMPA works by suppressing the menstrual cycle and reducing ovulation, thereby preventing pregnancy.
**Why the Correct Answer is Right:**
a) **Failure @ 0.3/100 WY:** The failure rate of DMPA refers to the number of women who become pregnant annually while using DMPA. A failure rate of 0.3/100 women-years indicates a high contraceptive effectiveness, making this option incorrect.
b) **150 mg/3 monthly delivered:** DMPA comes in a 150 mg dose, but the correct answer should mention the frequency of administration. DMPA is given as an intramuscular injection every 3 months, not once every 3 months.
c) **Weight gain:** DMPA might cause mild to moderate weight gain in some users due to fluid retention and redistribution of body fat. However, the correct answer should emphasize this is less common and not a universal side effect.
d) **Glucose intolerance occurs:** DMPA can cause mild hyperglycemia (elevated blood glucose levels) in some patients due to a decrease in insulin sensitivity, but this is not a universal side effect. The correct answer should mention that the risk of glucose intolerance is relatively low.
e) **Anemia improves:** DMPA may increase red blood cell mass, leading to improvement in anemia in some cases, particularly in women with a history of anemia. However, this is not a universal effect. The correct answer should emphasize that the improvement in anemia is observed in some patients.
**Why Each Wrong Answer is Incorrect:**
a) **Contraceptive failure at 0.3/100 women-years:** High contraceptive effectiveness (0.3/100 women-years) makes this option incorrect.
b) **150 mg dose administered every 3 months:** The correct answer should mention the frequency of administration (every 3 months) and emphasize that the dose is 150 mg.
c) **Frequent mood swings:** While some users may experience changes in mood, this is not a universal side effect. The correct answer should mention that mood changes are not always observed.
d) **Increased blood glucose levels:** Though some patients experience hyperglycemia (elevated blood glucose levels), the risk of glucose intolerance is relatively low. The correct answer should emphasize that glucose intolerance is not universal.
e) **Increased blood pressure:** DMPA may transiently increase blood pressure in some patients, but this is not a universal side effect. The correct answer should mention that blood pressure changes are not always observed.
f) **
