A nurse is reinforcing teaching with a client who is starting digoxin therapy to treat heart failure. The nurse should reinforce with the client that which of the following adverse effects is a possible indication of digoxin toxicity and should be reported to the provider?

A. Keep the finger in a dependent position:

• Keeping the finger in a dependent position (lower than the heart) helps promote blood flow to the fingertips, making it easier to obtain a blood sample. This position can facilitate the formation of a blood drop, improving the chances of obtaining an adequate sample for testing.

B. Wear sterile gloves:

• Sterile gloves are not typically necessary for routine capillary blood glucose monitoring. Clean, non-sterile gloves are generally sufficient for this procedure. However, the nurse should perform proper hand hygiene to minimize the risk of contamination.

C. Select the central tip of a finger:

• The central tip of the finger is more sensitive, and choosing this area may cause greater discomfort for the client. The sides of the fingertips are often preferred for capillary blood glucose testing as they have a good blood supply and are less sensitive.

D. Test the first drop of blood that forms after the puncture:

• The initial drop may contain tissue fluid or contaminants from the puncture site, so it is important to use the first drop to obtain a representative blood sample. This step contributes to the accuracy of the blood glucose measurement.

The correct answer is C. Hearing voices is a common symptom of psychotic disorders, such as schizophrenia. The nurse should first assess if the client is at risk of harming themselves or others due to the content of the voices. This is a priority intervention that can help prevent potential violence or suicide. The other statements are not appropriate as initial responses. A walk outside may not stop the voices and may expose the client to more stimuli that could worsen their condition. Asking the client to listen to the nurse instead of the voices may be perceived as dismissive or challenging by the client. Acknowledging that the voices are real to the client but not to the nurse may help establish rapport, but it does not address the urgency of assessing for safety.
