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:

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.

Choice A rationale:

Drowsiness alone may not be a reliable indicator of pain, as it can result from various factors such as medications or the postoperative recovery process. While pain might cause drowsiness in some cases, it is not a definitive nonverbal sign of pain.

Choice B rationale:

Grimacing is a nonverbal behavior that often indicates pain or discomfort. It involves facial expressions of pain, such as frowning or wincing. Grimacing is a significant indicator that the nurse should consider in assessing the client's pain level.

Choice C rationale:

Screaming is a more overt expression of pain and discomfort. However, it is less common in a postoperative setting and might also be associated with anxiety or other emotional states. While it can indicate pain, it's not as reliable a marker as grimacing, moaning, or restlessness.

Choice D rationale:

Moaning is a nonverbal behavior that can signal pain in a postoperative client. It's an audible expression of discomfort and should be considered as a potential indication of pain.

Choice E rationale:

Restlessness can be an indication of pain as well. The client may shift positions frequently or exhibit signs of agitation in response to pain. However, restlessness can also have other causes, such as anxiety or medication effects.
