56. The practical nurse (PN) is caring for a client who has a tracheostomy tube. After donning sterile gloves, in which sequence should the PN should implement these interventions? (Arrange from the first action on top to last on the bottom.)

The finding that is the highest priority for the PN to report to the charge nurse is the blood urea nitrogen (BUN) level of 75 mg/dL or 12.9 mmol/L. This result indicates an elevated BUN level, which can be indicative of impaired kidney function. In a client receiving chemotherapy, an elevated BUN level may suggest chemotherapy-induced nephrotoxicity or other kidney-related complications. Prompt reporting is crucial to ensure appropriate intervention and management of the client's kidney function.
B. While the platelet count of 135,000/mm3 or 135 x 109/L is slightly below the normal reference range, it does not pose an immediate life-threatening risk. However, it should still be monitored and reported to the healthcare team for ongoing assessment and evaluation.
C. Decreased deep tendon reflexes may be an expected side effect of certain chemotherapy medications or a manifestation of neurotoxicity. While this finding should be documented and monitored, it is not as urgent as the elevated BUN level.
D. Periodic nausea and vomiting are common side effects of chemotherapy, but they may also be indicative of other underlying issues such as dehydration, electrolyte imbalances, or gastrointestinal complications. While this finding should be addressed and managed, it is not the highest priority compared to the elevated BUN level.

This is the correct answer because it is the best way to assess for signs of ototoxicity, which is a potential adverse effect of aminoglycosides. Ototoxicity is the damage or injury to the inner ear or auditory nerve caused by certain drugs or chemicals. It can result in hearing loss, tinnitus, vertigo, or balance problems. Aminoglycosides are a class of antibiotics that are effective against gram-negative bacteria, but they can also cause ototoxicity by interfering with the function of the hair cells in the cochlea.

The practical nurse (PN) should monitor the client's hearing by asking about any changes in hearing acuity, ringing in the ears, or difficulty understanding speech. The PN should also perform a hearing test using a tuning fork or an audiometer if available. The PN should report any signs of ototoxicity to the healthcare provider and discontinue the aminoglycoside as ordered.
