A nurse accidentaly administers metformin instead of metoprolol to a client. Which of the following actions should the nurse take?

A. Aspirate before administering the medication: Aspirating is not recommended for subcutaneous heparin injections, as it can increase the risk of tissue trauma and hematoma formation. Proper technique involves pinching the tissue and injecting slowly without aspiration.

B. Monitor INR levels: INR is used to monitor warfarin therapy, not heparin. Heparin therapy is typically monitored using aPTT or anti-Xa levels depending on the protocol, so INR monitoring is not appropriate in this context.

C. Withhold the medication for an elevated platelet count: Heparin-induced thrombocytopenia is a concern when platelet counts drop, not when they are elevated. Withholding heparin for high platelet counts is unnecessary.

D. Validate the dosage with a second nurse: Heparin is considered a high-alert medication, and verifying the correct dosage with a second nurse helps prevent medication errors and enhances client safety during administration.

A. "You should take a stool softener while taking this medication.": Oxycodone is an opioid that commonly causes constipation by slowing gastrointestinal motility. Taking a stool softener or other bowel regimen helps prevent discomfort and promotes regular bowel movements.

B. "You should minimize exposure to sunlight while taking this medication.": Photosensitivity is not a typical adverse effect of oxycodone. Limiting sun exposure is unnecessary unless the client is taking other medications that increase photosensitivity.

C. "You should take this medication on an empty stomach.": Oxycodone can be taken with or without food. Taking it on an empty stomach may increase gastrointestinal discomfort rather than improve absorption.

D. "You might urinate more frequently while taking this medication.": Opioids like oxycodone often cause urinary retention, not increased urination. This statement does not reflect the expected pharmacologic effect.
