A Cardiovascular nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
Toe.
Earlobe.
Skin fold.
Finger.
The Correct Answer is B
Choice A rationale:
Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.
Choice B rationale:
The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.
Choice C rationale:
Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.
Choice D rationale:
While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.

Correct Answer is D
Explanation
Choice A rationale:
Applying petroleum jelly to the nares is not necessary in this situation. Oxygen therapy through a nasal cannula aims to deliver oxygen to the client's respiratory system. Applying petroleum jelly might interfere with the oxygen delivery and is not a standard practice.
Choice B rationale:
Removing the nasal cannula while the client eats reduces the oxygen supply during a time when the body's oxygen demand might increase due to the digestive process. It's important to maintain consistent oxygen therapy, even during meals.
Choice C rationale:
Attaching a humidifier bottle to the base of the flow meter is not necessary for oxygen therapy at 5 L/min via nasal cannula. Humidification is usually needed at higher oxygen flow rates to prevent drying of the mucous membranes.
Choice D rationale:
Securing the oxygen tubing to the bed sheet near the client's head is the correct action. This ensures that the tubing is not pulled or tugged during movement, maintaining a steady flow of oxygen. Placing it near the client's head prevents kinking or tangling of the tubing and allows the client to move without disrupting the therapy.
Correct Answer is A
Explanation
Choice A rationale:
Instructing the client not to adjust the oxygen flow rate is crucial to ensure the appropriate amount of oxygen is delivered. Oxygen flow rates are prescribed by a healthcare provider based on the client's needs, and altering the flow rate without medical guidance can lead to inadequate oxygen delivery or oxygen toxicity.
Choice B rationale:
Weekly equipment checks are important, but this choice is not the most critical instruction. Clients should be instructed to check their oxygen equipment daily for proper functioning and to address any issues promptly. Waiting a whole week could lead to potential problems going unnoticed.
Choice C rationale:
Storing unused oxygen tanks horizontally is incorrect. Oxygen tanks should be stored upright to prevent leaks and ensure proper functioning. Storing them horizontally can cause valve damage and leakage, which could lead to hazards.
Choice D rationale:
Using wool blankets on the bed is not a suitable instruction for a client using oxygen therapy. Wool blankets can generate static electricity, which might pose a fire hazard in the presence of oxygen-enriched environments.
