A nurse is collecting data from an older adult client who is receiving ondansetron IV, has a history of diabetes mellitus and cardiac myopathy, and is receiving chemotherapy to treat cancer. For which of the following adverse effects of ondansetron should the nurse monitor? (Select all that apply)

Volume to administer (mL) = Dose ordered (mg) / Concentration of drug (mg/mL).

For a dose of 15 mg and a concentration of 10 mg/mL, the calculation would be 15 mg / 10 mg/mL = 1.5 mL.

Therefore, the nurse should administer 1.5 mL of morphine injection.

D. After administering the PPD solution intradermally, the nurse should not withdraw the needle and massage the site. Massaging can cause the PPD to disperse outside the intended area and affect the accuracy of the test result. Instead, the nurse should gently blot the site with a gauze pad if there is any bleeding, without massaging.

A. For a Mantoux tuberculin skin test, the standard technique involves injecting a small amount of tuberculin purified protein derivative (PPD) intradermally to create a wheal or bleb that is typically 6 mm in diameter. If the nurse creates a bleb significantly larger or smaller than the recommended size, it could affect the interpretation of the test result.

B. It's important to avoid visualizing the needle tip under the skin during the injection. This can lead to inaccurate placement of the PPD solution, potentially resulting in an improperly administered test.

C. Stretching the skin tightly before injection is actually a correct technique for performing a Mantoux tuberculin skin test. This helps stabilize the injection site and ensures the needle is inserted at the correct angle for an intradermal injection.
