People living in poverty are most likely to obtain health care from:

Correct Answer: D

Rationale: People living in poverty often face barriers to accessing regular healthcare services, leading them to seek care in Emergency Departments or urgent care centers. These facilities are more accessible and do not require appointments or insurance, making them a common choice for individuals with limited resources. Neighborhood clinics, while a good option, may not always be available or affordable for those in poverty. Specialists provide specialized care but usually require a referral from a primary care provider, which individuals in poverty may not have consistent access to. Therefore, Emergency Departments or urgent care centers are the most likely sources of healthcare for people living in poverty.

Correct Answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

Correct Answer: C

Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.

Correct Answer: D

Rationale: Inhalation injury is the most common cause of injury from a house fire. When a fire occurs, the smoke produced contains harmful gases and particles that can be inhaled, leading to serious respiratory issues. This makes inhalation injury the primary concern during a house fire. Choices A, B, and C are less likely to be the primary cause of injury. While explosions may occur in some cases, inhalation of smoke and toxic fumes is generally the most prevalent danger. Falls from windows and thermal damage to the skin are also significant risks but typically occur after inhalation injuries in the sequence of events during a house fire.

Correct Answer: D

Rationale: Getting a back rub and drinking a glass of warm milk are appropriate measures to promote sleep as they can help relax the body and induce sleepiness. Exercising vigorously, as suggested in choice A, can be counterproductive as it stimulates the body rather than relaxing it, making it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, may also increase alertness due to the temperature changes and the caffeine in tea, which can interfere with falling asleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, making it harder to fall asleep. Therefore, choice D is the best option to promote sleep in this scenario.
