Why is glucose an important molecule in a cell?
- A. Extraction of energy
- B. Synthesis of protein
- C. Building of genetic material
- D. Formation of cell membranes
Correct Answer: A
Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

A client with Cushing's syndrome has been prescribed a diet low in sodium. The nurse knows that the client should avoid which of the following foods?
- A. Bananas
- B. Spinach
- C. Processed meats
- D. Oatmeal
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.
The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?
- A. Decreased blood glucose levels
- B. Decreased urine ketones
- C. Increased serum bicarbonate
- D. Increased anion gap
Correct Answer: D
Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.
The client with Addison's disease is receiving education on managing the condition. Which of the following instructions should be included?
- A. Increase your sodium intake during periods of stress.
- B. Avoid all types of exercise.
- C. Decrease your fluid intake to prevent fluid overload.
- D. Stop corticosteroid therapy once symptoms improve.
Correct Answer: A
Rationale: The correct instruction to include for a client with Addison's disease is to increase sodium intake during periods of stress. In Addison's disease, there is a deficiency of aldosterone leading to sodium loss. Increasing sodium intake helps to compensate for this loss and prevent complications. Choice B is incorrect as exercise is beneficial for overall health but should be done in moderation. Choice C is incorrect as fluid intake should be adequate to prevent dehydration since clients with Addison's disease are prone to electrolyte imbalances. Choice D is incorrect as corticosteroid therapy is essential for managing Addison's disease and should not be discontinued abruptly without medical guidance.
A client with type 2 DM is being taught about the importance of foot care. Which instruction should the nurse include?
- A. Wear comfortable shoes that allow air circulation.
- B. Walk barefoot whenever possible.
- C. Use a heating pad to warm your feet.
- D. Soak your feet in hot water every night.
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.
A client with diabetes mellitus is scheduled for surgery. The nurse should prioritize which of the following preoperative actions?
- A. Administer a full dose of insulin before surgery
- B. Hold all oral hypoglycemic agents the day before surgery
- C. Monitor blood glucose levels closely before surgery
- D. Instruct the client to avoid all fluids the morning of surgery
Correct Answer: C
Rationale: Monitoring blood glucose levels closely before surgery is the priority for a client with diabetes mellitus. This allows for early detection of any abnormalities and helps prevent hypo- or hyperglycemia complications that can arise during the perioperative period. Option A is incorrect because insulin dosing should be individualized based on the client's current blood glucose levels and the surgical plan. Option B is incorrect as abruptly holding oral hypoglycemic agents can lead to uncontrolled blood glucose levels. Option D is incorrect as adequate fluid intake is important for the client's hydration status and overall well-being before surgery.
