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."
None
None
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 D
Explanation
Choice A reason: A client with diabetes mellitus presenting with acute ketoacidosis does not necessarily require a private room unless there are other infection control concerns. Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones. It is a medical emergency that requires treatment in a hospital, but it is not contagious.
Choice B reason: An older adult client admitted with aspiration pneumonia would not typically require a private room solely based on this condition. Aspiration pneumonia is caused by inhaling food, stomach acid, or saliva into the lungs. It can lead to a bacterial infection, which may or may not be contagious depending on the causative organism.
Choice C reason: A client with a compound fracture of the right femur would not require a private room based on the diagnosis alone. A compound fracture, also known as an open fracture, is a fracture in which there is an open wound or break in the skin near the site of the broken bone. While it requires immediate medical attention to prevent infection, it is not a condition that necessitates isolation.
Choice D reason: A client who reports having fever, night sweats, and cough for 2 days may require a private room due to the possibility of an infectious disease that could be transmitted to others, such as tuberculosis (TB). These symptoms are concerning for TB, which is an airborne infectious disease and would require airborne precautions, including a private room with negative pressure ventilation.
Correct Answer is B
Explanation
Choice A reason: Changing the ostomy pouch daily is not typically necessary. Most pouches can be worn comfortably for several days before needing to be changed. Frequent changes are not only unnecessary but can also irritate the skin around the stoma.
Choice B reason: Emptying the ostomy pouch when it is 2/3 full is recommended to prevent leaks and overfilling, which can lead to discomfort and potential skin irritation. It is important to monitor the fullness of the pouch and empty it regularly to maintain hygiene and comfort.
Choice C reason: Trimming the opening of the ostomy seal to be 1/2 inch wider than the stoma is incorrect. The opening should be cut to match the size of the stoma to ensure a snug fit that prevents leakage and protects the skin around the stoma.
Choice D reason: Applying lotion to the peristomal skin when changing the ostomy pouch is not advised. Lotions or creams can interfere with the adhesive of the ostomy appliance and should be avoided. The peristomal skin should be clean and dry to ensure proper adhesion of the ostomy appliance.
