Correct Answer is B

Explanation

Choice A reason: Pressing down on the orbital area of the eye is not a recommended method for eliciting a pain response due to the risk of causing injury to the eye.

Choice B reason: Pinching the trapezius muscle is a common and safe method to elicit a pain response in an unresponsive patient. It is less invasive and carries a lower risk of injury compared to other methods.

Choice C reason: Using a 25-gauge needle is not a standard practice for eliciting a pain response due to the risk of puncture and infection.

Choice D reason: Eliciting a reflex with a reflex hammer is used to assess neurological function, not to elicit a pain response in an unresponsive patient.

A. "I will draw the regular insulin into the syringe first." B. "I will store prefilled syringes in the refrigerator with the needle pointed upward." C. "I will gently roll the NPH vial between my hands before drawing up the insulin." D. "I will insert the needle at a 90-degree angle."

Correct Answer is A

Explanation

Choice A reason: Drawing the regular insulin into the syringe first is correct. When mixing two types of insulin, the clear (regular) insulin should be drawn up before the cloudy (NPH) insulin to prevent contamination.

Choice B reason: Storing prefilled syringes with the needle pointed upward can cause air bubbles to move into the insulin, which can alter the dose when injected. The needle should be pointed downward.

Choice C reason: Shaking the NPH vial vigorously is not recommended as it can create air bubbles and affect the insulin dose. Instead, the vial should be gently rolled between the hands to mix the insulin.

Choice D reason: Inserting the needle at a 15-degree angle is incorrect for subcutaneous injections. A 90-degree angle is typically used unless the patient is very thin, in which case a 45-degree angle may be used.
