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
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
Withholding the medication until the prescribing provider is available could potentially put the patient at risk, especially if the medication is critical for the patient’s health and well-being.
Choice B rationale
Requesting to speak with the provider who is covering for the prescriber is the most appropriate action in this situation. This allows the nurse to clarify the prescription and ensure the safety of the patient.
Choice C rationale
Contacting the pharmacy to confirm that the dosage is safe to administer could be a part of the process, but it should not be the first step. The nurse should first contact a healthcare provider to discuss the prescription.
Choice D rationale
Informing the charge nurse and administering the usual dose of the medication without first consulting with a healthcare provider could potentially put the patient at risk.
Correct Answer is D
Explanation
Choice A rationale
Tachycardia is not a common adverse effect of oxygen therapy. It is more likely to be associated with conditions such as fever, anemia, or hypoxia.
Choice B rationale
Poor skin turgor is a sign of dehydration, not a typical adverse effect of oxygen therapy. Oxygen therapy does not directly affect the body’s hydration status.
Choice C rationale
Excessive pulmonary secretions are not a direct adverse effect of oxygen therapy. Conditions such as pneumonia or bronchitis often cause increased secretions.
Choice D rationale
Cracks in the oral mucous membranes can occur as a result of oxygen therapy. Oxygen can dry out the mucous membranes, leading to discomfort and potential cracking.
