Correct Answer: B

Rationale: Community health nurses are primarily responsible for populations. While they do provide care and support to individuals and families within the community, their focus is on the health and well-being of entire populations. Choice A is incorrect as the primary responsibility is broader than just individuals. Choice C is incorrect as families are part of the population but not the sole focus. Choice D, 'class E citizens', is too specific and not a standard term in public health, making it an incorrect choice.

Correct Answer: A

Rationale: The correct answer is A. Focusing on the older children's needs during the initial days at home is crucial as it helps them feel secure and valued during the transition. This approach allows the children to adjust to the new family dynamics and feel included in the care of their newborn sister. Choice B is incorrect as it focuses on tasks rather than addressing the children's emotional needs. Choice C is not the initial step and does not involve directly addressing the children's needs. Choice D puts the decision-making burden on the children rather than providing guidance and support.

Correct Answer: A

Rationale: The correct answer is A. Audible wheezing and grunting in an infant indicate respiratory distress, which is a critical condition requiring immediate assessment and intervention by the healthcare provider. Choices B, C, and D do not present with immediate life-threatening conditions that require urgent evaluation. Soot on the face and shirt, second-degree burns on the hand, and singed hair, while concerning, do not pose an immediate threat to life compared to respiratory distress in an infant.

Correct Answer: A

Rationale: Vaginal bleeding immediately after birth is most often due to uterine atony, which is the failure of the uterus to contract following delivery. This results in inadequate compression of blood vessels at the placental site, leading to hemorrhage. Genital lacerations and abnormal clotting mechanisms can also cause bleeding but are less common immediately after birth compared to uterine atony. Endometritis, inflammation of the lining of the uterus, usually presents with symptoms like fever and pelvic pain rather than immediate postpartum bleeding.

Correct Answer: B

Rationale: The client's inability to effectively clear the airway due to pain and sputum production hinders the cough mechanism, making 'Ineffective airway clearance' the most appropriate nursing diagnosis. Although impaired gas exchange may occur due to the pneumonia, the immediate issue is the inability to clear the airway. 'Ineffective breathing pattern' does not address the specific issue of airway clearance. 'Anxiety' is not the priority when the focus should be on the physical complications of pneumonia.
