Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: D

Rationale: Negligence refers to the failure to take proper care in doing something. In this scenario, the nurse failed to exercise the standard of care expected in placing a heating pad directly on Mr. C's lower leg, knowing his history of peripheral vascular disease. This failure led to a burn and subsequent infection that required a skin graft for treatment. The actions of the nurse were negligent as they did not meet the expected standard of care, resulting in harm to the patient. This situation does not fit the definition of assault, malpractice, or vicarious liability, making negligence the most appropriate choice.

Correct Answer: D

Rationale: The initial step in the process of change for the senior nurse should be to identify the inefficiency that needs improvement or correction. Before setting goals, planning strategies, or identifying solutions, it is essential to first pinpoint the specific area or aspect that requires change. By identifying the inefficiency, the senior nurse can gain a clear understanding of the root cause of the issue and focus efforts on addressing it effectively. This step lays the foundation for the rest of the change process by providing a specific target for improvement.

Correct Answer: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.

Correct Answer: C

Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.

Correct Answer: C

Rationale: Type 2 diabetes mellitus is characterized by insulin resistance in the peripheral tissues and defective beta cell secretion with loss of insulin. In type 2 diabetes, there is typically not destruction of beta cells from an autoimmune mechanism that leads to lack of insulin and hyperglycemia as seen in type 1 diabetes mellitus. Instead, in type 2 diabetes, the pancreas initially produces insulin, but the body's cells become resistant to its effects. This results in hyperglycemia due to the inability of the body to properly regulate blood sugar levels. Therefore, choice C is not true for type 2 diabetes mellitus.
