A nurse is caring for a client with diabetes mellitus who is prescribed regular insulin via a sliding scale. After administering the correct dose at 0715, the nurse should ensure the client receives breakfast at which of the following times?
0730
0745
0815
0720
The Correct Answer is A
Choice A reason:
0730: Regular insulin, also known as short-acting insulin, typically begins to work within 30 minutes after administration. Therefore, ensuring the client receives breakfast at 0730, which is 15 minutes after the insulin dose, aligns with the onset of insulin action. This timing helps to prevent hypoglycemia by ensuring that glucose from the meal is available when the insulin starts to lower blood sugar levels.
Choice B reason:
0745: Administering breakfast at 0745, which is 30 minutes after the insulin dose, might be slightly delayed. While it is still within the effective window, it is better to have the meal a bit earlier to ensure that glucose is available as soon as the insulin begins to act.
Choice C reason:
0815: Providing breakfast at 0815, which is an hour after the insulin dose, is too late. By this time, the insulin would have already started to lower blood glucose levels significantly, increasing the risk of hypoglycemia. It is crucial to match the timing of food intake with the insulin action to maintain stable blood sugar levels.
Choice D reason:
0720: Serving breakfast at 0720, which is only 5 minutes after the insulin dose, is too early. The insulin would not have started to act yet, and the blood glucose levels might rise too high before the insulin begins to lower them. It is important to wait at least 15-30 minutes after administering regular insulin before eating.

Correct Answer is C
Explanation
Choice A reason:
Using the palm of the hand, feel for lumps using a circular motion: This instruction is incorrect. The correct method for a breast self-exam involves using the pads of the three middle fingers, not the palm of the hand. The fingers should move in a circular motion to feel for lumps or abnormalities.
Choice B reason:
Expect some breast dimpling or discharge with age: This is misleading and potentially harmful advice. While some changes in the breast can occur with age, dimpling or discharge can also be signs of breast cancer and should be reported to a healthcare provider immediately.
Choice C reason:
Breasts can be examined in the shower with soapy hands: This is correct. Examining the breasts in the shower with soapy hands can make it easier to feel for lumps or changes. The soapy water helps the fingers glide smoothly over the skin, making it easier to detect any abnormalities.
Choice D reason:
For those who have a menstrual cycle, perform a BSE every month, 2 or 3 days before menstruation: This instruction is incorrect. The best time to perform a breast self-exam is a few days after the menstrual period ends, when the breasts are least likely to be swollen or tender.
Correct Answer is ["0.8"]
Explanation
Step 1: Determine the dosage required. Required dosage = 30 mg
Step 2: Determine the concentration of the available solution. Available concentration = 40 mg/mL
Step 3: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 30 mg ÷ 40 mg/mL
Step 4: Perform the division. 30 ÷ 40 = 0.75
Step 5: Round the answer to the nearest tenth. Rounded volume = 0.8 mL
The nurse should administer 0.8 mL.
