A patient has an order for a subcutaneous injection of insulin.
Into which of the following tissues will the nurse prepare to give this injection?
Into the patient’s intravenous line.
Into the patient’s vastus lateralis.
Into the fatty tissue of the patient’s abdomen.
Into the patient’s deltoid.
The Correct Answer is C
Choice A rationale:
Intravenous (IV) administration delivers medication directly into the bloodstream. This route is not appropriate for insulin because it would result in a rapid and potentially dangerous drop in blood glucose levels. Insulin needs to be absorbed more slowly to mimic the natural release of insulin from the pancreas.
IV administration also requires sterile technique and specialized equipment, making it more complex and time-consuming than subcutaneous injection.
Additionally, there is a higher risk of infection and other complications with IV administration.
Choice B rationale:
The vastus lateralis is a muscle in the thigh that is commonly used for intramuscular (IM) injections. However, IM injections are not typically used for insulin administration because they can be more painful and have a slower absorption rate than subcutaneous injections.
IM injections also carry a higher risk of hitting a blood vessel, which could lead to erratic absorption of insulin.
Choice D rationale:
The deltoid is a muscle in the upper arm that can be used for subcutaneous injections. However, the abdomen is generally the preferred site for insulin injection because it has a greater amount of subcutaneous fat, which helps to slow the absorption of insulin and provide a more consistent effect.
The abdomen is also a more convenient site for self-injection, as it is easily accessible.
Choice C rationale:
The fatty tissue of the abdomen is the ideal site for subcutaneous insulin injection because it provides slow and consistent absorption of insulin.
The abdomen has a rich blood supply, which helps to distribute the insulin throughout the body.
The subcutaneous tissue in the abdomen is relatively thin, which makes it easy to inject insulin without causing pain or discomfort.
The abdomen is also a large area, which allows for multiple injection sites to be used and rotated to prevent lipohypertrophy (thickening of the subcutaneous tissue).

Correct Answer is B
Explanation
Choice A rationale:
A lactose-free diet does not contraindicate acupuncture therapy. Lactose intolerance is a digestive condition that does not affect blood clotting or the ability to receive acupuncture safely.
Acupuncture needles are very fine and do not typically cause bleeding. Even if minor bleeding occurs, it is not a concern for individuals without bleeding disorders.
Therefore, a lactose-free diet does not pose a risk for acupuncture.
Choice B rationale:
Thrombocytopenia is a condition characterized by a low platelet count. Platelets are essential for blood clotting. Acupuncture involves the insertion of needles into the skin. This can cause minor bleeding, even when performed correctly.
In individuals with thrombocytopenia, even minor bleeding can be difficult to control and may lead to excessive bruising or hematoma formation.
Therefore, thrombocytopenia is a contraindication to acupuncture therapy due to the increased risk of bleeding complications.
Choice C rationale:
Herniated lumbar disks are a common condition that can cause back pain. Acupuncture is often used to treat back pain, including pain caused by herniated disks.
Studies have shown that acupuncture can be effective in reducing pain and improving function in patients with herniated disks.
Therefore, the presence of herniated lumbar disks does not contraindicate acupuncture therapy.
Choice D rationale:
Latex and strawberry allergies are not contraindications to acupuncture therapy. Acupuncture needles are typically made of stainless steel, which does not contain latex.
Additionally, acupuncture does not involve the use of strawberries or any other substances that are common allergens. Therefore, latex and strawberry allergies do not pose a risk for acupuncture.
Correct Answer is C
Explanation
Choice A rationale:
Debridement refers to the removal of dead, damaged, or infected tissue to promote healing. It is not a term used to describe skin breakdown caused by moisture.
Choice B rationale:
Evisceration is the protrusion of internal organs through a wound or surgical incision. It is not relevant to the condition of perineal skin breakdown due to wetness.
Choice D rationale:
Dehiscence is the separation of a surgical wound. It is not applicable in this case, as there is no mention of a surgical wound.
Choice C rationale:
Maceration is a term used to describe skin that has become softened and broken down due to prolonged exposure to moisture. This is the most accurate term to describe the condition of perineal skin breakdown after sitting in wet underclothes for many hours.
Key features of maceration:
Skin softening: The skin becomes white and wrinkled, resembling a prune.
Epidermal loss: The outer layer of skin (epidermis) may slough off, leaving the underlying tissue exposed. Redness: The affected area may become red and inflamed.
Pain or tenderness: The area may be painful or tender to the touch.
Increased risk of infection: Macerated skin is more susceptible to infection due to the breakdown of the skin barrier. Causes of maceration:
Prolonged exposure to moisture: This can include sweat, urine, feces, wound drainage, or excessive bathing. Friction: Rubbing or chafing of the skin can also contribute to maceration.
Impaired circulation: Poor blood flow to the area can make it more vulnerable to maceration. Prevention of maceration:
Keep skin clean and dry: This is the most important step in preventing maceration. Change wet or soiled clothing or dressings promptly.
Apply barrier creams or ointments: These can help to protect the skin from moisture.
Use incontinence products: These can help to keep the skin dry if the patient is incontinent. Reposition the patient frequently: This helps to reduce pressure and friction on the skin.
