A nurse on the Cardiovascular unit is completing the patient's history and physical examination. Which of the following information provided by the patient should the nurse consider as subjective data?

Choice A rationale:

Asking the patient why this medication has been ordered is not the appropriate action because patients might not have accurate medical knowledge to provide a valid explanation for the prescription. The nurse should rely on healthcare professionals for accurate information.

Choice B rationale:

Verifying with the hospital administration is not necessary in this situation. The decision to prescribe medication is made by the healthcare provider, not the hospital administration.

Choice C rationale:

Verifying with the prescribing healthcare provider is the most appropriate action. The healthcare provider has the medical knowledge and rationale for prescribing a specific medication. This ensures that the nurse administers the medication safely and in alignment with the patient's condition and treatment plan.

Choice D rationale:

Asking another nurse might not yield accurate information about the rationale behind the medication order. It's best to directly communicate with the healthcare provider responsible for the patient's care.

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.
