A nurse is preparing to administer testosterone gel to a client who has hypogonadism. Which of the following actions should the nurse take?

A. The nurse should wear gloves when handling testosterone gel to prevent accidental absorption, but clean gloves are insufficient; disposable protective gloves must be used for safety. B. The gel should never be applied to the genital region because it can cause skin irritation and unpredictable absorption. Recommended sites include the shoulders, upper arms, or abdomen, depending on the brand. C. Waiting at least 1 hour before showering or swimming ensures full absorption of testosterone into the skin, maintaining therapeutic efficacy and preventing unintentional transfer to others. D. Serum testosterone levels are typically checked after several weeks (not 1 week) of therapy to allow stabilization and accurate assessment of the dosage’s effectiveness.
