A nurse in the Medical-Surgical unit is caring for a client who has had an allogeneic hematopoietic stem-cell transplant. Which of the following infection-control precautions should the nurse use while caring for this client?

The correct answer is: d. Left fifth intercostal space at the midclavicular line.

Choice A: Left fourth intercostal space at the sternal border

The fourth intercostal space at the sternal border is not the typical location for the Point of Maximal Impulse (PMI). This area is more commonly associated with the tricuspid valve auscultation point. The PMI is usually found more laterally and inferiorly.

Choice B: Left third intercostal space at the sternal border

The third intercostal space at the sternal border is also not the correct location for the PMI. This area is generally used for auscultating the pulmonic valve. The PMI is located further down and towards the midclavicular line.

Choice C: Left second intercostal space at the midclavicular line

The second intercostal space at the midclavicular line is typically where the aortic valve is auscultated. The PMI is not found this high up on the chest.

Choice D: Left fifth intercostal space at the midclavicular line

This is the correct location for palpating the Point of Maximal Impulse (PMI). The PMI is usually located at the apex of the heart, which is found at the left fifth intercostal space along the midclavicular line. This is where the left ventricle is closest to the chest wall and can be felt most strongly during systole.

Choice A rationale:

It's essential to ensure that the client fully understands the surgical procedure and its implications before signing the informed consent form. If the client expresses confusion or lack of understanding, the nurse should involve the surgeon to address the concerns directly. The surgeon is the most appropriate person to provide comprehensive information about the procedure, potential risks, benefits, and alternatives. This promotes patient autonomy and informed decision-making, aligning with ethical principles.

Choice B rationale:

While educating the client about the procedure is important, it's not the nurse's role to provide detailed explanations of surgical procedures. Additionally, the surgeon possesses the necessary expertise to explain medical procedures accurately. Relying on the surgeon for this explanation maintains professional boundaries and ensures accurate information dissemination.

Choice C rationale:

Encouraging the client to reread the consent form is insufficient if the client did not initially understand the explanation. The consent form might contain complex medical language, and the client might need direct communication with the surgeon to address specific concerns. Merely re-reading the form might not alleviate the client's confusion.

Choice D rationale:

Telling the client that the surgeon will explain the procedure in the operating room is inappropriate. The client's concerns should be addressed promptly, and the explanation should occur before the surgery, allowing the client to make an informed decision. Operating rooms are not the appropriate setting for obtaining informed consent.
