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

Answer and Explanation

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 ["2"]

Explanation

Step 1: Determine the dosage required. Required dosage = 150 mg

Step 2: Determine the dosage available per tablet. Available dosage per tablet = 75 mg

Step 3: Calculate the number of tablets needed. Number of tablets needed = Required dosage ÷ Available dosage per tablet Number of tablets needed = 150 mg ÷ 75 mg

Step 4: Perform the division. 150 ÷ 75 = 2

The nurse should administer 2 tablets per dose.

A. Administer the medications 5 minutes apart. B. Hold pressure on the conjunctival sac for 2 minutes following application of drops. C. It is not necessary to remove contact lenses before administering medications. D. Administer the medications by touching the tip of the dropper to the sclera of the eye.

Correct Answer is A

Explanation

Choice A reason: Administer the Medications 5 Minutes Apart

Administering the medications 5 minutes apart is crucial when using multiple eye drops. This practice ensures that each medication has enough time to be absorbed without being washed out by the subsequent drop. This is particularly important for medications like timolol and pilocarpine, which are used to manage intraocular pressure in glaucoma.

Choice B reason: Hold Pressure on the Conjunctival Sac for 2 Minutes Following Application of Drops

Holding pressure on the conjunctival sac (punctal occlusion) for 2 minutes after applying eye drops can help reduce systemic absorption and increase the local effect of the medication. However, this instruction is not as critical as the timing between administering different eye drops.

Choice C reason: It Is Not Necessary to Remove Contact Lenses Before Administering Medications

This statement is incorrect. Contact lenses should be removed before administering eye drops to prevent contamination and ensure proper absorption of the medication. The lenses can be reinserted after a sufficient amount of time has passed, usually around 15 minutes.

Choice D reason: Administer the Medications by Touching the Tip of the Dropper to the Sclera of the Eye

This statement is incorrect. The tip of the dropper should never touch the eye or any other surface to avoid contamination. The correct method is to hold the dropper above the eye and squeeze out the prescribed number of drops into the conjunctival sac.
