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: When assessing a client's mobility status, it is crucial to start by examining their gait. Gait assessment is usually conducted as the client walks into the room. Normal gait is described as smooth, flowing, and rhythmic without the need for assistive devices. Choices B, C, and D are incorrect as they do not represent the standard practice of beginning the assessment of mobility status with gait examination.

Correct Answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

Correct Answer: C

Rationale: To provide total oral care to a client, the nurse should first assemble all necessary equipment. Placing the client in a side-lying position helps fluids to easily flow out or pool in the side of the mouth for suctioning, thus preventing aspiration. Additionally, placing a towel under the client's chin and a curved basin against the chin helps to maintain cleanliness during the procedure. Choice A is incorrect because the client should be placed in a side-lying position, not a semi-Fowler's position which is used for respiratory issues. Choice B is incorrect as it does not emphasize the importance of proper positioning for effective oral care. Choice D is incorrect as it oversimplifies the procedure by focusing only on cleaning the mouth without considering the importance of positioning and preparation.

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: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.

Correct Answer: D

Rationale: During active exercise, insulin sensitivity increases, leading to lower blood glucose levels. To balance the effect of increased insulin sensitivity, additional carbohydrates might be needed. The other choices are incorrect because: A) an infection typically raises blood glucose levels rather than increasing the need for carbohydrates; B) emotional upset can impact blood glucose but does not directly affect carbohydrate needs; C) while a large meal can raise blood glucose levels, it does not necessarily mean an increase in carbohydrate needs.

Correct Answer: C

Rationale: For a 4-year-old client struggling to sleep in the hospital, the best nursing intervention is to identify the child's home bedtime rituals and follow them. Preschool-age children often have specific bedtime routines that provide comfort and promote sleep. This familiarity can help create a sense of security in an unfamiliar hospital environment. Choice A, turning off the room light and closing the door, may increase the child's fear of the dark and being alone. Choice B, engaging the child in calming activities before bedtime, is a better choice than tiring them with play exercises. Choice D, encouraging relaxation techniques like deep breathing exercises, although helpful, may not be as effective as following the child's familiar bedtime routines.

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.
