A middle-aged client reports, "I can't get my breath when I walk." Upon assessment, the nurse notes that the patient has a barrel chest and is using his accessory muscles to breathe. The patient's respiratory rate is 28/min. On palpation, there is limited expansion and decreased tactile fremitus. Percussion yields hyperresonant sounds. On auscultation, prolonged expiration, scattered wheezes, and rhonchi are present. Which disorder would the nurse suspect?

Choice A rationale:

Washing hands for 5 to 10 seconds prior to administering medication is indeed an important safety measure, but it is not specifically related to changing or applying a transdermal patch. Hand hygiene is crucial to prevent the spread of infection, but it doesn't directly address the process of applying a patch.

Choice B rationale:

Applying the patch over a non-hairy area within the patient's skin is the correct answer. This is crucial because hair can interfere with the adhesion of the patch, leading to inadequate drug absorption. The rationale behind this is to ensure that the medication is effectively delivered through the skin into the bloodstream without any barriers such as hair. It's also important to choose a site that is clean, dry, and free from cuts or irritation.

Choice C rationale:

Leaving the previous medication patch in place is not recommended. It's essential to remove the old patch before applying a new one to prevent accumulation of the medication and to ensure accurate dosing. Failing to remove the previous patch could lead to an overdose or altered drug effects.

Choice D rationale:

Ensuring that the patient is lying down is not a specific safety measure for changing or applying a transdermal patch. The patient's position doesn't directly impact the effectiveness of the patch or the safety of the application process.

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.
