Correct Answer: A

Rationale: The correct first step for thermal protection of a newborn is to dry the baby thoroughly immediately after birth. This helps prevent heat loss and is crucial in maintaining the baby's body temperature. Choice B, covering the baby with a clean, dry cloth after the cord has been cut, is not the initial step as drying the baby comes first. Choice C, drying the baby thoroughly after the cord has been cut, is also not the first step. Choice D, covering the baby with a clean, dry cloth immediately after birth, is not as effective as drying the baby to prevent heat loss.

Correct Answer: B

Rationale: Prevalence is the correct answer as it refers to the number of existing cases of a disease in a specific population at a given time. Incidence, on the other hand, refers to the number of new cases of a disease in a defined population over a specific period. Mortality rate is the measure of the number of deaths in a particular population due to a specific cause, while morbidity rate is the frequency of a disease in a specific population.

Correct Answer: B

Rationale: In situations where a client's condition worsens and the caregiver is no longer able to provide sufficient care, the first action to implement is to assign a home health care aide to provide daily care. This ensures that the client's immediate needs are met and that they receive proper care and support. Requesting a chaplain for counseling (Choice A) may be beneficial but is not the most urgent action. Discussing placing the wife in a nursing home (Choice C) should only be considered after assessing the client's needs and exploring all other options. Contacting the client's children (Choice D) can be helpful but does not address the immediate need for daily care that the client requires.

Correct Answer: D

Rationale: Epidemiological studies are used by community health nurses to identify the health needs of a population. These studies involve investigating patterns, causes, and effects of health and disease conditions in defined populations. While health surveys, medical records, and patient interviews are valuable tools in healthcare, epidemiological studies provide a broader population-based perspective essential for understanding and addressing community health needs.

Correct Answer: D

Rationale: Building a healthy community is indeed based on principles like concreteness, group dynamics, and focusing on community-level change. However, stating that environmental factors are more basic than institutional factors is incorrect. Both environmental and institutional factors play crucial roles in community health. Environmental factors like access to healthcare, clean water, and safe housing are vital, while institutional factors such as healthcare systems, education, and governance also significantly impact community health. Therefore, the correct answer is D, as environmental factors are not more basic than institutional factors.
