A nurse is reviewing the BUN and creatinine levels of an older adult patient with chronic kidney disease. The nurse should anticipate which of the following findings?
BUN 8 mg/dL and creatinine 0.7 mg/dL
BUN 45 mg/dL and creatinine 8 mg/dL
BUN 23 mg/dL and creatinine 1.0 mg/dL
BUN 10 mg/dL and creatinine 0.3 mg/dL
The Correct Answer is B
Choice A reason:
A BUN level of 8 mg/dL and a creatinine level of 0.7 mg/dL are within normal ranges for a healthy individual without kidney disease. In chronic kidney disease (CKD), we would expect these values to be elevated due to the kidneys' reduced ability to filter waste products from the blood.
Choice B reason:
A BUN level of 45 mg/dL and a creatinine level of 8 mg/dL are significantly higher than the normal range, which is consistent with impaired kidney function seen in CKD. These elevated levels indicate that the kidneys are not effectively filtering urea and creatinine from the blood, leading to their accumulation.
Choice C reason:
A BUN level of 23 mg/dL and a creatinine level of 1.0 mg/dL could be seen in the early stages of CKD. While the creatinine level is within the normal range, the BUN level is slightly elevated, which may suggest a decline in kidney function.
Choice D reason:
A BUN level of 10 mg/dL and a creatinine level of 0.3 mg/dL are both below the normal range. This is an unlikely finding for a patient with CKD, as kidney impairment typically leads to increased levels of these substances in the blood.

Correct Answer is C
Explanation
Choice A reason:
Informatics involves the use of information technology in healthcare, which is essential for managing patient data and improving communication. However, while informatics supports various aspects of patient care, it is not the primary concern during the perioperative period. The focus during this time is on ensuring the client's immediate well-being and preventing harm.
Choice B reason:
Quality improvement is a continuous process of identifying and implementing changes to improve patient care and outcomes. While it is a critical component of nursing practice, the priority in the perioperative period is the safety of the client, which is a more immediate concern.
Choice C reason:
Safety is the most critical QSEN competency during the perioperative period. This period involves significant risks due to anesthesia, surgical procedures, and potential complications. Ensuring the client's safety by preventing errors, reducing the risk of harm, and maintaining a sterile environment is paramount.
Choice D reason:
Evidence-based practice involves using the best current evidence to make informed decisions about patient care. While it is crucial for guiding clinical practice, the immediate priority in the perioperative period is ensuring the client's safety through vigilant monitoring and intervention.
Correct Answer is D
Explanation
Choice A reason:
Annular lesions are ring-shaped with a clear center, which does not describe a lesion with a wavy border. This term is typically used for lesions like ringworm, which present as circular rashes with normal skin in the center.
Choice B reason:
Circinate lesions are also circular but are not characterized by a wavy border. They are similar to annular lesions but often have a more rounded edge and are associated with conditions like psoriasis.
Choice C reason:
Coalesced lesions refer to multiple lesions that have merged to form a larger one. While they can have irregular borders, 'coalesced' does not specifically describe the wavy nature of the border.
Choice D reason:
Serpiginous lesions have a wavy or snake-like border, which matches the description provided by the nurse. This term is often used for parasitic infections, such as cutaneous larva migrains, which create a trail-like pattern on the skin.
