A fracture in which the skin is open and the bone may come through the skin is a(n)

Correct Answer: B

Rationale: The correct answer is B: Open fracture. An open fracture involves the skin being broken, allowing the bone to protrude through the skin. This poses a high risk of infection due to exposure of the bone to the external environment. Closed fractures (A) do not involve any break in the skin. Greenstick fractures (C) are incomplete fractures commonly seen in children. Compression fractures (D) occur when bones are crushed, often seen in the spine. Therefore, an open fracture best describes a fracture with an open wound and bone protrusion.

Correct Answer: A

Rationale: The correct answer is A: Immune system weakens. As people age, their immune system tends to weaken, leading to decreased ability to combat infections and illnesses effectively. This is a normal age-related change due to factors such as thymus gland atrophy and reduced immune cell function. B: Antibody response speeds up - This is incorrect as aging typically results in a slower and less efficient immune response. C: Number of T-cells increases - This is incorrect as the number of T-cells actually decreases with age, leading to a weakened immune response. D: Response to vaccines increases - This is incorrect as older individuals often have a diminished response to vaccines due to their weakened immune system.

Correct Answer: B

Rationale: Intubation is the correct answer because it refers to the method of inserting an artificial airway into the trachea to help facilitate breathing. Telemetry is the monitoring of physiological parameters, not airway insertion. Ventilation is the process of moving air in and out of the lungs, not the method of inserting an airway. Dyspnea is the sensation of difficult or labored breathing, not a method of airway insertion.

Correct Answer: C

Rationale: The correct answer is C (15) because the federal government mandates 12-24 hours of continuing education annually for nursing assistants, with 15 hours falling within this range. Choice A (10) is below the minimum requirement, choice B (12) is at the minimum threshold, and choice D (18) exceeds the maximum limit. The correct answer aligns with federal regulations for nursing assistant continuing education hours.

Correct Answer: C

Rationale: The correct answer is C: Someone has touched a resident without his consent. Battery in legal terms refers to the intentional and unauthorized physical contact with another person, which includes touching without consent. This choice aligns with the definition of battery and accurately describes the legal term. Explanation for other choices: A: Someone has improperly used a resident's money - This describes financial exploitation, not battery. B: Someone has used profanity with a resident - This describes verbal abuse, not battery. D: Someone has shared a resident's protected health information with someone who is not on the care team - This describes a breach of privacy, not battery.
