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:

Dyspnea (shortness of breath) is a common finding in clients with emphysema. Emphysema is a chronic obstructive pulmonary disease characterized by the destruction of lung tissue, leading to reduced lung elasticity and airflow limitation, which can result in difficulty breathing.

Choice B rationale:

Clubbing of the fingers is another expected finding in clients with advanced emphysema. Clubbing is the swelling and rounding of the fingertips, often associated with chronic respiratory conditions. It is thought to be a result of chronic hypoxia and inadequate oxygenation.

Choice C rationale:

Deep respirations are not typically associated with emphysema. Clients with emphysema often exhibit shallow, rapid respirations due to the loss of lung tissue elasticity, which impairs the normal respiratory mechanics.

Choice D rationale:

Bradycardia (slow heart rate) is not a common finding in emphysema. Emphysema primarily affects the respiratory system and does not directly influence heart rate. Bradycardia could be related to other factors but is not a characteristic finding of emphysema.

Choice E rationale:

Barrel chest is a classic physical finding in clients with emphysema. It results from the hyperinflation of the lungs due to the trapping of air in the damaged alveoli. This gives the chest a rounded appearance, similar to the shape of a barrel.
