The practical nurse (PN) is auscultating the lung fields of a client exhibiting a low-pitched, grating sound during inspiration and expiration. The PN notes that coughing does not clear the sound. Which term best describes this lung sound?

Rationale:

A. Use a penlight to observe the pupillary response to light and document the findings: Assessment of pupillary response evaluates cranial nerve II and III function and is part of a broader neurological or eye exam. However, the immediate next step after testing one eye for visual acuity is to assess the other eye under the same conditions to obtain a complete and comparable evaluation.

B. Tell the client to step to the next marked line, keep the right eye covered, and repeat the procedure: Changing the client’s position alters the standardized testing distance of 20 feet, which is essential for the validity of Snellen visual acuity results. Moving closer would distort the measurement and does not follow proper testing protocol.

C. Instruct the client to cover the left eye and repeat the procedure while standing in the same spot: Visual acuity must be assessed separately for each eye to identify unilateral or bilateral deficits. Maintaining the same distance ensures consistency and accuracy of results. Testing the other eye immediately after completing the first eye follows standard screening procedure.

D. Advise the client to meet with a healthcare provider about the need for corrective lenses: A result of 20/20 indicates normal visual acuity in the tested eye, so there is no immediate indication for referral. Recommendations for corrective lenses should be based on abnormal findings or functional complaints rather than normal screening results.

Rationale:

A. Position the client on the left side and reassess: Placing the client in the left lateral decubitus position shifts the heart closer to the chest wall, making the PMI easier to palpate, especially in older adults or clients with a thick chest wall. This maneuver is a standard initial approach to improve assessment accuracy before concluding that the apical site is non-palpable.

B. Document the lack of an apical pulse in the medical record: Recording a missing apical impulse without further assessment is premature. The inability to palpate the PMI in the supine position can be influenced by positioning or body habitus, additional assessment techniques should be attempted first.

C. Assess the client for signs of diminished cardiac output: While important for overall cardiac assessment, evaluating for symptoms such as hypotension, fatigue, or altered mentation does not address the immediate issue of locating the PMI. This action is supportive but not the priority initial step.

D. Count the pulse rate and volume at the radial site: Measuring the radial pulse provides information on peripheral perfusion but does not substitute for assessing the apical impulse, which is critical for detecting dysrhythmias or confirming heart rate and rhythm, particularly in a bedfast client.
