What is an important guideline to follow when administering a transdermal patch?
Remove the old patch before applying a new one and rotate application sites.
Apply the patch to the site of the old patch.
Apply the patch to the waist area.
Apply the patch to an area of skin with or without hair.
The Correct Answer is A
A. Remove the old patch before applying a new one and rotate application sites: Removing the old patch prevents drug overdose from residual medication. Rotating application sites reduces skin irritation and ensures consistent absorption, which is a key safety and efficacy guideline for transdermal therapy.
B. Apply the patch to the site of the old patch: Applying a new patch to the same site repeatedly can cause local irritation, skin breakdown, and inconsistent absorption. Rotation of sites is recommended instead.
C. Apply the patch to the waist area: The waist is not a standard or recommended site for most transdermal patches. Sites such as the upper arm, chest, or back are preferred for proper adhesion and absorption.
D. Apply the patch to an area of skin with or without hair: Hair can interfere with patch adhesion and drug absorption. Patches should be applied to clean, dry, and mostly hairless skin, or hair should be trimmed (not shaved) if necessary.

A. Polyethylene glycol, an osmotic laxative:Polyethylene glycol is used to treat constipation by drawing water into the intestines. It does not prevent chemotherapy-induced nausea or vomiting and is not effective for this purpose.
B. Omeprazole, a proton pump inhibitor:Omeprazole decreases gastric acid production and is used for gastroesophageal reflux or ulcers. It does not prevent chemotherapy-induced nausea or vomiting and is not indicated for prophylaxis.
C. Loperamide, an opioid:Loperamide is an antidiarrheal that slows intestinal motility. It does not prevent nausea or vomiting related to chemotherapy and is not used for this purpose.
D. Ondansetron, a selective 5-HT3 receptor antagonist given 30 minutes before chemotherapy:Ondansetron blocks serotonin receptors in the chemoreceptor trigger zone and gastrointestinal tract, preventing nausea and vomiting. Administering it 30 minutes before chemotherapy provides effective prophylaxis, in patients with severe chemotherapy-induced nausea and vomiting.
Correct Answer is B
Explanation
A. Document the adverse reaction in the patient’s chart:Documentation is important for legal and clinical records but is not the immediate priorityin a life-threatening situation. Patient safety comes first.
B. Assess the patient's airway, breathing, and circulation:Facial swelling and difficulty breathing indicate a potential anaphylactic reaction, which can be rapidly fatal. The nurse must first assess and maintain airway patency, oxygenation, and circulation before taking other actions.
C. Notify the provider immediately:Notifying the provider is necessary, but the nurse must first ensure the patient’s airway and vital functions are stable. Immediate intervention can be lifesaving.
D. Administer another dose of the medication to counteract the adverse reaction:Administering another dose would worsen the reaction. The priority is halting exposureand initiating emergency treatment, such as epinephrine if indicated.
