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: A

Rationale: The primary responsibility for obtaining informed consent lies with the surgeon who will be performing the procedure. Informed consent is a process where the healthcare provider explains the procedure, benefits, risks, and alternatives to the patient, allowing them to make an informed decision about their care. While other healthcare team members may also participate in this process, the ultimate responsibility typically rests with the surgeon as they are the one performing the surgery.

Correct Answer: A

Rationale: When a patient is receiving too much insulin, the most likely result is hypoglycemia, not hyperglycemia. The excess insulin causes the blood glucose level to drop too low, leading to symptoms such as sweating, tremors, confusion, and in severe cases, seizures. The body responds to hypoglycemia by releasing counterregulatory hormones such as glucagon, epinephrine, and cortisol, which work to increase the blood glucose level. This rebound effect, known as the Somogyi effect, can result in the patient experiencing high blood glucose levels after a period of insufficient glucose supply due to excessive insulin administration.

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: A

Rationale: Nursing intervention should prioritize providing education on proper incisional wound care techniques to promote optimal healing of the abdominal incision. This may include instructions on how to clean the incision site, signs and symptoms of infection, and when to seek medical attention. Proper wound care can help prevent complications such as infection and dehiscence, leading to better outcomes for the client. Administering prophylactic antibiotics, encouraging the use of abdominal binders, and instructing the client on activity restrictions are also important interventions, but educating the client on wound care techniques is crucial for their active participation in their recovery process.
