Why is a primigravida instructed to offer her breast to the baby for the first time within 30 minutes after delivery?

Correct Answer: C

Rationale: Rationale: 1. Primigravida refers to a woman pregnant for the first time. 2. Colostrum is the first milk produced after childbirth, rich in antibodies and nutrients. 3. Offering the breast within 30 minutes ensures the baby receives this vital colostrum. 4. Colostrum provides immune protection and establishes the baby's gut microbiome. 5. Options A and B relate to mature milk production, not colostrum. 6. Option D focuses on practice, not the immediate benefits of colostrum.

Correct Answer: D

Rationale: The correct answer is D: Post-natal care. Post-natal care refers to the care given to a woman within a month after delivering a baby. This care is crucial for monitoring the mother's physical and emotional health, providing support with breastfeeding, ensuring proper healing, and addressing any postpartum complications. Follow-up care (A) is a general term that may include various types of care beyond the immediate post-natal period. Maternity care (B) typically refers to the care provided during pregnancy and childbirth, not specifically after delivery. Puerperal care (C) specifically focuses on the period immediately following childbirth and may not encompass the entire month post-delivery.

Correct Answer: B

Rationale: The correct answer is B: OPV. The oral polio vaccine (OPV) used in the Expanded Program on Immunization (EPI) is stored in the freezer to maintain its potency. OPV is a live vaccine that requires cold storage to prevent the virus from becoming inactive. DPT, Hepatitis B vaccine, and Measles vaccine are typically stored in the refrigerator, not the freezer, as they are either killed or attenuated vaccines that remain stable at higher temperatures. Therefore, the need for freezer storage specifically points to OPV as the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Immunization coverage. This is the most effective measure as it ensures a high percentage of the population is vaccinated, leading to herd immunity. This reduces the spread of diseases. Cold chain (B) ensures vaccine quality but doesn't directly control disease occurrence. Potency of vaccines (C) is important but doesn't address population coverage. Health education (D) is valuable but doesn't directly prevent disease spread like high immunization coverage does.

Correct Answer: A

Rationale: The correct answer is A: BCG. BCG vaccine is administered through intradermal injection, leaving a small scar due to the immune response it triggers. The scar formation is a characteristic feature of the BCG vaccine and is used as an indicator of successful vaccination. Other vaccines like DPT, Hepatitis B, and Measles do not typically leave a permanent scar at the injection site. The scar formation with BCG vaccine is a result of the body's immune response to the live attenuated Mycobacterium bovis strain in the vaccine, leading to a localized inflammatory reaction and subsequent scarring.
