The nurse auscultates the precordium of a client who is diagnosed with mitral valve regurgitation and hears a grade IV systolic murmur. When documenting the comparison of systolic murmurs, which characteristics should the nurse use to support this systolic finding?

A. In the context of detecting papilledema, "inspection" refers to using an ophthalmoscope to examine the optic disc for swelling. Papilledema, which is swelling of the optic disc due to increased intracranial pressure, can only be observed through this direct examination of the eye’s interior. This technique is the most appropriate and accurate for confirming papilledema as it allows the nurse to visually inspect the optic disc for signs of swelling or other abnormalities.
B. Percussion involves tapping on the body to assess underlying structures and is commonly used in evaluating lung and abdominal sounds. It is not used for assessing the optic nerve or papilledema. Therefore, percussion is not relevant for confirming the presence of papilledema.
C. Palpation involves feeling the body’s surface to assess for abnormalities such as swelling or
tenderness. It is used for evaluating various parts of the body but does not apply to detecting papilledema. Papilledema involves changes to the optic nerve head, which cannot be assessed through palpation.
D. Auscultation involves listening to internal body sounds using a stethoscope, such as heartbeats, lung sounds, or abdominal sounds. This technique is not used to assess the optic disc or detect papilledema. It is not relevant for the diagnosis of conditions affecting the optic nerve.

A. The presence of crepitus, regardless of size, indicates air trapped in the subcutaneous tissue, which can be associated with various conditions including trauma, infection, or underlying lung issues. Therefore, it is important to evaluate the finding further rather than assuming it is insignificant.
B. This is the most accurate interpretation. Crepitus is indeed an abnormal finding and warrants further investigation. Its presence can indicate underlying issues such as subcutaneous emphysema, which may be related to trauma, infections, or other conditions that need to be addressed. A more detailed assessment, including possible imaging or additional diagnostic tests, should be pursued to determine the cause and appropriate management.
C. While it is true that subcutaneous air can be absorbed over time, the presence of crepitus is still an abnormal finding that needs to be evaluated. The underlying cause of the trapped air must be identified, as it may indicate an injury or other health issues that require intervention. Simply assuming that it will resolve on its own without further investigation could overlook a potentially serious condition.
D. While a fractured rib can cause crepitus, this finding alone does not necessarily mean an immediate chest x-ray is required. The decision to order an x-ray should be based on a comprehensive assessment of the client’s symptoms, history, and physical examination findings. Although a rib fracture is a possible cause, other conditions such as subcutaneous emphysema or infections should also be considered.
