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:
Resuming sexual intercourse in 2 to 3 weeks may not be appropriate for all patients after such a major surgery. The recovery time can vary based on individual factors, including the extent of the surgery and the patient's overall health. It's essential for patients to follow their healthcare provider's specific recommendations, which typically involve waiting until after the postoperative check-up, usually around 6 weeks, to ensure proper healing.
Choice B reason:
Increased vaginal drainage typically occurring 5 days following surgery could be a sign of infection or other complications. Normal postoperative discharge should gradually decrease over time. If a patient experiences increased drainage, especially if it's foul-smelling or accompanied by fever, they should contact their healthcare provider immediately.
Choice C reason:
After a total abdominal hysterectomy and bilateral salpingo-oophorectomy, patients may experience vaginal dryness due to decreased estrogen levels. Using artificial lubricants can help alleviate symptoms of itching and dryness, making this an appropriate instruction for postoperative care.
Choice D reason:
A Papanicolaou (Pap) test is not typically required every 6 months after a total abdominal hysterectomy and bilateral salpingo-oophorectomy for uterine cancer unless the surgery was performed as treatment for cervical cancer or serious pre-cancer. For those who had the procedure due to benign conditions, further Pap tests are generally not necessary.
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.
