What is the appropriate action to take if a child is found to have a fever on the day of immunization?

Correct Answer: B

Rationale: The correct action is to delay the immunization until the fever subsides. This is because administering a vaccine during a fever may affect the body's immune response and efficacy of the vaccine. Giving a lower dose (choice C) may not provide adequate protection. Administering an antipyretic (choice D) may temporarily reduce fever but does not address the underlying illness causing the fever. Administering the vaccine as scheduled (choice A) can be harmful and is not recommended when the child has a fever.

Correct Answer: B

Rationale: The correct answer is B: Children aged 1-4 years. This age group is most vulnerable to PEM due to their rapid growth and development, high energy requirements, and dependency on caregivers for nutrition. Infants below 6 months are typically protected by breast milk, adolescents have lower risk due to fewer growth demands, and elderly are more at risk for other types of malnutrition. Therefore, children aged 1-4 years are the most vulnerable to PEM.

Correct Answer: C

Rationale: The primary purpose of administering Vitamin K to newborns is to prevent bleeding disorders. Vitamin K is essential for the production of blood clotting factors, which helps prevent excessive bleeding. Newborns are born with low levels of Vitamin K, putting them at risk for bleeding disorders like vitamin K deficiency bleeding. Administering Vitamin K at birth helps ensure proper blood clotting function. The other choices are incorrect because Vitamin K does not directly prevent infection, promote growth, or enhance immune function in newborns.

Correct Answer: C

Rationale: The correct answer is C: Measles, Mumps, Rubella (MMR) vaccine. Live attenuated vaccines contain weakened forms of the virus. MMR vaccine is made from weakened live viruses of measles, mumps, and rubella. When administered, the body develops an immune response without causing the disease. Choice A, Hepatitis B vaccine, is a subunit vaccine. Choice B, Inactivated polio vaccine, is a killed virus vaccine. Choice D, Diphtheria, Tetanus, Pertussis (DPT) vaccine, is a toxoid vaccine. Live attenuated vaccines provide stronger and longer-lasting immunity as they mimic natural infection without causing illness.

Correct Answer: C

Rationale: The correct answer is C: 12 months. The first dose of the MMR vaccine is typically administered at 12 months of age because this is when a child's immune system is more developed to respond effectively to the vaccine. Administering it earlier may not provide adequate protection. Choice A (At birth) is incorrect because newborns have maternal antibodies that can interfere with the vaccine's efficacy. Choice B (6 months) is too early as infants need time to develop their immune system. Choice D (18 months) is also incorrect as delaying the vaccine may leave the child vulnerable to diseases like measles, mumps, and rubella.
