A patient with supraventricular tachycardia (SVT) is prescribed verapamil. Which nursing intervention is essential for the nurse to implement when administering verapamil

A. Place one finger across the acromion process and measure fingerbreadth below to the midpoint and center of the lateral aspect of the upper arm: This technique accurately identifies the deltoid muscle injection site, avoiding the acromion and underlying nerves or blood vessels. Proper site selection ensures safe and effective intramuscular administration of the hepatitis B vaccine.

B. Locate the center of the arm between the elbow and the shoulder: This is too vague and does not ensure injection into the deltoid muscle belly. Administering here may risk injecting into subcutaneous tissue or near nerves.

C. Locate the middle third of the anterior thigh between the greater trochanter of the femur and the lateral femoral condyle: This describes the vastus lateralis site, used for infants or adults who cannot use the deltoid. It is not appropriate for routine adult deltoid injections.

D. Find the center of the anterior aspect of the thigh: This incorrectly identifies the anterior thigh (rectus femoris) rather than the lateral thigh (vastus lateralis) or deltoid. This site is less recommended for adults due to pain and proximity to nerves.

A. Corticosteroids increase the immune response and enhance inflammation, aggravating symptoms:Corticosteroids inhibit multiple inflammatory pathways rather than stimulating them. Increasing immune activity would worsen mucosal inflammation in inflammatory bowel disease. This mechanism is opposite to the therapeutic goal of corticosteroid therapy.

B. Corticosteroids balance electrolytes and water in the body, improving gut motility:Although corticosteroids can affect fluid and electrolyte balance as a side effect, this is not the therapeutic mechanism in inflammatory bowel disease. Symptom relief occurs through anti-inflammatory effects on the intestinal mucosa.

C. Corticosteroids suppress the immune system and reduce inflammation, helping to improve symptoms in inflammatory bowel disease:Corticosteroids decrease leukocyte migration and inhibit the release of inflammatory mediators in the intestinal wall. Reduced inflammation leads to decreased edema, ulceration, and mucosal damage. This mechanism helps control disease flares and improve clinical symptoms.

D. Corticosteroids increase the production of proinflammatory cytokines, improving symptoms in inflammatory bowel disease:Corticosteroids reduce the production of proinflammatory cytokines such as interleukins and tumor necrosis factor. Increasing cytokine production would intensify intestinal inflammation.
