Correct Answer: A

Rationale: The correct instruction for a client with type 2 diabetes mellitus (DM) regarding foot care is to wear comfortable shoes that allow air circulation. This recommendation helps prevent foot injuries and infections, which are common concerns for individuals with diabetes. Choice B, walking barefoot, can increase the risk of injuries and wounds due to reduced sensation in the feet often seen in diabetes. Choice C, using a heating pad, can lead to burns or skin damage if the temperature is not carefully monitored, making it an unsafe practice. Choice D, soaking feet in hot water every night, can also be harmful as it can cause burns and dry out the skin, leading to further complications for individuals with diabetes. Therefore, the most appropriate and safe advice is to wear comfortable shoes that promote air circulation to maintain foot health and prevent complications.

Correct Answer: A

Rationale: The correct answer is A: Veracity. Veracity is the ethical principle of truthfulness and honesty in communication. When a nurse provides truthful information to a patient, it demonstrates integrity and respect for the patient's right to know the truth about their health condition and treatment. Choice B, Autonomy, refers to respecting the patient's right to make their own decisions. Choice C, Justice, involves fairness and equality in healthcare decisions. Choice D, Nonmaleficence, relates to the obligation to do no harm and prevent harm to the patient.

Correct Answer: C

Rationale: The correct answer is C: Processed meats. Clients with Cushing's syndrome who are on a low-sodium diet should avoid processed meats because they are typically high in sodium. Bananas, spinach, and oatmeal are generally low in sodium and can be included in a low-sodium diet. Bananas are a good source of potassium, spinach is rich in vitamins and minerals, and oatmeal is a healthy whole grain option. Therefore, choices A, B, and D are not the best options to avoid for a client with Cushing's syndrome following a low-sodium diet.

Correct Answer: B

Rationale: Following a transsphenoidal hypophysectomy, it is crucial to avoid activities such as coughing, sneezing, and blowing the nose to prevent an increase in intracranial pressure or the risk of cerebrospinal fluid leakage. Coughing, sneezing, or nose blowing can strain the surgical site, potentially leading to complications. Lying flat for 24 hours is not typically required after this surgery. Fluid intake should be encouraged to prevent dehydration. Ringing in the ears is not a common complication associated with this type of surgery.

Correct Answer: A

Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make their own decisions, including the right to refuse treatment. This principle acknowledges the patient's self-governance and independence in making choices about their own healthcare. Choice B, Nonmaleficence, refers to the ethical principle of doing no harm and ensuring patient safety. Choice C, Beneficence, involves promoting the patient's well-being and acting in their best interest. Choice D, Justice, pertains to fairness and equitable distribution of healthcare resources.
