A nurse is preparing to measure a client’s oxygen saturation and notes edema of the client’s hands and thickened toenails.
Where should the nurse apply the pulse oximeter probe?

Toe

Finger

Skin fold

Earlobe

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is B

Explanation

Choice A rationale

The statement “The client should first move the strong leg then the weak one” is not the best practice when using a cane. The client should move the cane and the weak leg forward at the same time, then move the strong leg.
Choice B rationale
The statement “When the client moves, he should move the cane forward first” is the correct practice. Moving the cane first provides stability and support for the next step.
Choice C rationale
The statement “The client should hold the cane on the weak side of his body” is not the correct practice. The cane should be held on the strong side of the body to provide support for the weak side.
Choice D rationale
The statement “The grip should be level with the client’s waist” is a good practice, but it’s not the best answer for this question. The grip of the cane should be at the level of the client’s wrist when the client’s arm is hanging down. This allows the client to maintain a slight bend in their elbow when holding the cane.

A. Place a 1-inch needle on the syringe. B. Hold the syringe at a 20° angle to the client’s skin. C. Draw up 0.5 mL of purified protein derivative (PPD) from the vial. D. Pinch the skin at the chosen site with the non-dominant hand before inserting the needle.

Correct Answer is C

Explanation

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.
