A nurse is providing teaching for a client who has diabetes mellitus about the self-administration of insulin. The client has prescriptions for regular and NPH insulins. Which of the following statements by the client indicates an understanding of the teaching?
"I will draw the regular insulin into the syringe first."
"I will store prefilled syringes in the refrigerator with the needle pointed upward."
"I will gently roll the NPH vial between my hands before drawing up the insulin."
"I will insert the needle at a 90-degree angle."
The Correct Answer is A
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.

Correct Answer is B
Explanation
Choice A reason: Moving the client to a double room may not be effective in preventing wandering and could potentially lead to confusion or agitation if the client is not comfortable with the roommate or the new environment.
Choice B reason: Using a bed alarm is a non-invasive way to alert staff if the client attempts to leave the bed. This can help prevent wandering and ensure the safety of the client without restricting their movement unnecessarily.
Choice C reason: Encouraging participation in activities that provide excessive stimulation is not recommended for clients with dementia, as it can lead to increased confusion, agitation, and potentially exacerbate wandering behaviors.
Choice D reason: The use of chemical restraints, such as sedative medications, should be a last resort and only used when necessary to ensure the safety of the client or others. It is important to use the least restrictive measures first and to always consider the ethical implications of using chemical restraints.
Correct Answer is B
Explanation
Choice A reason : Desmopressin is a medication used to treat conditions like diabetes insipidus and certain cases of hemophilia, not allergic reactions such as hives and urticaria.
Choice B reason: Diphenhydramine is an antihistamine that is commonly used to treat allergic reactions, including hives and urticaria. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
Choice C reason: Spironolactone is a diuretic and is not used to treat allergic reactions. It is typically prescribed for conditions like heart failure, hypertension, and certain hormonal disorders.
Choice D reason: Metoclopramide is a medication used to treat nausea and gastroparesis, not allergic reactions.
