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:

Auscultation at the pulmonic and mitral points would not provide the clearest hearing of the S2 heart sound. The S2 sound is composed of two components: A2 (aortic valve closure) and P2 (pulmonic valve closure). The aortic valve sound (A2) is usually louder than P2. Mitral point is not ideal for hearing S2 clearly, as it's mostly associated with S1 sound.

Choice B rationale:

The tricuspid and aortic points are the most appropriate for hearing the S2 heart sound. The aortic valve (A2) is best heard at the second right intercostal space close to the sternum, and the tricuspid valve is best heard at the lower left sternal border.

Choice C rationale:

While the mitral and tricuspid points are important for auscultating the heart sounds, they are more associated with the S1 sound (the first heart sound). The S2 sound is best heard at the aortic and pulmonic areas.

Choice D rationale:

The aortic and pulmonic points are important for assessing the S2 heart sound, but they are not the most optimal locations. The aortic valve sound is heard most clearly at the second right intercostal space, whereas the pulmonic valve sound is heard at the second left intercostal space.

Choice A rationale:

Veracity refers to truthfulness and honesty in communication between the healthcare provider and the client. It involves providing accurate information and not deceiving the client. Discontinuing the experimental medication due to kidney failure demonstrates a commitment to the truth, but the primary ethical principle demonstrated here is nonmaleficence.

Choice B rationale:

Autonomy refers to respecting the client's right to make their own decisions about their healthcare. In this scenario, the medication was discontinued due to evidence of harm to the client's health. This action prioritizes the client's well-being over their autonomy to continue the treatment.

Choice C rationale:

Nonmaleficence, or the principle of "do no harm," is demonstrated in this scenario. The experimental medication was discontinued because it was causing rapidly advancing kidney failure. The healthcare provider's decision to stop the treatment is an example of prioritizing the client's safety and well-being by preventing further harm.

Choice D rationale:

Fidelity refers to being loyal, keeping promises, and maintaining trust in the nurse-client relationship. While this principle is important, it doesn't directly apply to the situation described, where the focus is on the ethical responsibility to prevent harm.
