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)

D. Tachycardia refers to an elevated heart rate. In circulatory overload, the heart may attempt to compensate for the increased fluid volume by pumping faster. This compensatory mechanism aims to maintain adequate tissue perfusion despite the excessive fluid burden.

A. Diaphoresis refers to excessive sweating. It is not typically associated with circulatory overload. Instead, diaphoresis can occur in conditions such as fever, anxiety, or during physical exertion.

B Hypotension refers to low blood pressure. In circulatory overload, the excess fluid in the circulatory system can lead to increased blood pressure rather than hypotension. Hypotension is more commonly associated with hypovolemia (low blood volume) rather than hypervolemia.

C. Weight loss is not a characteristic finding in circulatory overload. On the contrary, patients with fluid overload often experience weight gain due to retained fluid in the body tissues and bloodstream.

D. Holding the skin taut helps stabilize the area and ensures that the needle penetrates the skin smoothly and at the correct angle. This also helps prevent the needle from going too deep or slipping out of the site during injection.

A. The syringe should be held at a 5 to 15-degree angle to the client's skin, not 20 degrees.

B. For a tuberculin skin test (PPD test), typically 0.1 mL (one-tenth of a milliliter) of PPD is injected intradermally. This is a very small amount compared to 0.5 mL.

C. The length of the needle for an intradermal injection is typically shorter than 1 inch, usually around 3/8 to 5/8 inches (10-16 mm). Using a longer needle may increase the risk of inserting the needle too deeply, potentially leading to subcutaneous rather than intradermal injection.
