Correct Answer: C

Rationale: The correct statement about breastfeeding is that breastmilk given exclusively for the first 4 to 6 months of life helps avoid the introduction of infection. This practice is recommended by health experts for optimal infant health. Choice A is incorrect because breastfeeding should ideally start within the first hour after birth to stimulate breastmilk production. Choice B is incorrect because breastmilk should be initiated as soon as possible after delivery, not after 24 hours. Choice D is incorrect because while feeding on demand is generally encouraged, it should also follow a schedule to ensure adequate nutrition and growth for the baby.

Correct Answer: A

Rationale: The correct answer is A because a client with diabetic ketoacidosis (DKA) that is being well-managed and has shown improvement within 24 hours is more stable and can be considered for discharge sooner than those with more acute or unstable conditions. Choice B is incorrect as Tylenol intoxication may require further monitoring and intervention. Choice C is incorrect as a client with an automatic defibrillator and episodes of passing out needs careful evaluation and monitoring. Choice D is incorrect as suspected bacterial meningitis is a serious condition that typically requires a longer hospital stay for treatment and observation.

Correct Answer: A

Rationale: Newborns are at the highest risk for hepatitis B virus due to potential transmission from the mother. The hepatitis B virus can be transmitted from an infected mother to her baby during childbirth. Children born to mothers infected with hepatitis B are at the highest risk of acquiring the infection. Choices B, C, and D are at lower risk compared to a newborn as they are less likely to have been exposed to the virus during childbirth.

Correct Answer: C

Rationale: The correct first action for the community health RN to take in this situation is to review current epidemiological population data that might document a low immunization rate. By doing so, the RN can gather evidence to support further intervention strategies. Option A is incorrect because taking a health history would not provide immediate data on immunization rates in the community. Option B is incorrect as initiating an immunization program without confirming the actual immunization rates may not address the specific needs of the community. Option D is incorrect as a blanket referral without assessing the situation may not be the most effective first step.

Correct Answer: C

Rationale: The correct answer is C because homeless individuals who are alcoholics and smoke have a higher risk of developing community-acquired pneumonia due to factors like poor living conditions, compromised immune systems, and increased exposure to infections. Choice A is less likely as the teacher's profession, while involving contact with children, may not pose as high a risk as the factors in choice C. Choice B may have respiratory issues but does not have the same risk factors as choice C. Choice D, the aerobics instructor, may have a healthy lifestyle but skipping meals and a restrictive diet do not directly correlate with a higher risk of pneumonia compared to the risk factors in choice C.
