A nurse is caring for a client who requires a clear liquid diet. Which food is acceptable for the client to consume?

Choice A rationale
Placing a 1-inch needle on the syringe is not appropriate for an intradermal injection such as a tuberculin skin test. Intradermal injections require a much shorter needle, typically 1/4 to 1/2 inch in length.
Choice B rationale
Holding the syringe at a 20° angle to the client’s skin is not correct for an intradermal injection. For an intradermal injection, the syringe should be held at a much shallower angle, typically about 5 to 15 degrees.
Choice C rationale

Drawing up 0.1 mL of purified protein derivative (PPD) from the vial is the correct action when preparing to administer a tuberculin skin test. This is the standard amount of PPD used for a tuberculin skin test.
Choice D rationale
Pinching the skin at the chosen site with the non-dominant hand before inserting the needle is not typically done for an intradermal injection. Instead, the skin is usually stretched taut to provide a flat surface for the injection.

Choice A rationale
Applying the pulse oximeter probe to the toe might not provide an accurate reading if the client has poor peripheral circulation. Additionally, thickened toenails can interfere with the reading.
Choice B rationale

Edema in the hands can affect the accuracy of a pulse oximeter reading. The probe might not fit properly or provide a reliable reading if the finger is swollen.
Choice C rationale
Applying the pulse oximeter probe to a skin fold is not recommended. The probe needs to be placed on a relatively flat, thin area of skin to accurately measure oxygen saturation.
Choice D rationale
The earlobe is a suitable alternative site for pulse oximetry if the fingers and toes are not viable options. The earlobe is typically less affected by peripheral vasoconstriction, which can occur with hypothermia, certain medications, and certain diseases. Therefore, Choice D is the correct answer.
