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 ["B","C","E"]
Explanation
Choice A reason:
Polyuria, or excessive urination, is not typically a direct complication of a cervical spinal cord injury. Polyuria can be related to other conditions such as diabetes or the use of diuretics.
Choice B reason:
A weakened gag reflex can be a complication of a cervical spinal cord injury, especially if the injury affects the nerves that supply the muscles involved in swallowing. This can increase the risk of aspiration and requires careful monitoring.
Choice C reason:
Hypotension, or low blood pressure, is a common complication following a spinal cord injury due to the disruption of the autonomic pathways that control blood pressure. This condition, known as neurogenic shock, can occur in the acute phase following the injury.
Choice D reason:
Hyperthermia, or elevated body temperature, is not a common direct complication of a cervical spinal cord injury. However, the injury can disrupt temperature regulation, leading to difficulty in either staying warm or cooling down, depending on the environment and level of injury.
Choice E reason:
An absence of bowel sounds can indicate a complication of a cervical spinal cord injury, as the injury may disrupt the normal functioning of the bowel. This can lead to ileus or bowel obstruction, which requires prompt medical attention.
Correct Answer is B
Explanation
Choice A reason:
While GERD (gastroesophageal reflux disease) can be exacerbated by hormone therapy due to its potential effect on the lower esophageal sphincter, it is not typically a contraindication for HT unless the GERD is severe and not well controlled with treatment.
Choice B reason:
A history of breast cancer is a contraindication for hormone therapy. Estrogen can stimulate the growth of hormone receptor-positive breast cancers, and therefore, HT is not recommended for individuals with a current or past history of breast cancer.
Choice C reason:
COPD (chronic obstructive pulmonary disease) is not a contraindication for HT. While patients with COPD may have other comorbidities that could affect the safety of HT, COPD alone does not preclude the use of hormone therapy.
Choice D reason:
Dermatitis, or inflammation of the skin, is not a contraindication for HT. Skin conditions are not typically affected by hormone therapy, and HT may sometimes be beneficial for skin health during menopause.
