Correct Answer: D

Rationale: The correct answer is D: hypoglycemia. In a diabetic patient, signs of irritability, irrational behavior, and visible tremors in the hands indicate low blood sugar levels, which is hypoglycemia. This is because the brain relies on glucose for energy, and when blood sugar levels drop too low, it can lead to neuroglycopenic symptoms such as confusion and tremors. Explanation for why the other choices are incorrect: A: hyperglycemia - High blood sugar levels typically present with symptoms such as frequent urination, increased thirst, and fatigue, not irritability and tremors. B: hyperglycemic hyperosmolar - This condition is characterized by extremely high blood sugar levels and severe dehydration, leading to symptoms such as extreme thirst and confusion, not irritability and tremors. C: diabetic ketoacidosis (DKA) nonketosis (HHNK) - These conditions are associated with high blood sugar levels and metabolic disturbances,

Correct Answer: B

Rationale: The correct answer is B: Suppressor T cells. Suppressor T cells regulate the immune response by inhibiting the activity of other immune cells to prevent overreaction and maintain immune balance. They play a crucial role in preventing autoimmune diseases and excessive inflammation. Plasma cells (A) produce antibodies, Helper T cells (C) assist in activating other immune cells, and B lymphocytes (D) are involved in antibody production. Suppressor T cells specifically have the function of shutting down immune responses, making them the immune system’s shutoff mechanism.

Correct Answer: A

Rationale: The correct answer is A: neuropathy on her peripheral. In diabetes, peripheral neuropathy is common, causing loss of sensation in the feet, making it difficult to feel injuries like stepping on a sharp object. This can lead to delayed detection of wounds, increasing the risk of infections and complications. Nephropathy (B) refers to kidney damage, carpal tunnel syndrome (C) involves compression of the median nerve in the wrist, and macroangiopathy (D) refers to large blood vessel disease, which are not directly related to the scenario described.

Correct Answer: B

Rationale: The correct answer is B, weight gain, as it is not typically considered a warning sign of cancer. Changes in bladder and bowel habits (A), indigestion or difficulty in swallowing (C), and a nagging cough or hoarseness (D) are commonly associated with various types of cancer. Weight gain is more commonly linked to factors such as diet, exercise, and hormonal imbalances rather than cancer. It is important to be vigilant about the other warning signs and seek medical attention if any of those symptoms persist.

Correct Answer: A

Rationale: The correct answer is A because protocols are indeed guidelines that assist clinicians in decision-making and choosing interventions for specific health care problems. This definition accurately reflects the purpose and function of protocols in nursing practice. Option B is incorrect as it describes protocols as policies related to nurses' duties and standards of care, which is more aligned with job descriptions and policies rather than protocols. Option C is incorrect as it relates protocols to a code of ethics, which is a separate concept that guides ethical decision-making and behavior in nursing practice. Option D is incorrect as it inaccurately describes protocols as prescriptive order forms, which are actually separate from protocols and are used for medication administration and treatment orders.
