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","D"]
Explanation
Choice A reason:
The statement "The client is Black" does not contribute to the risk of chlamydia based on race alone. Chlamydia infection rates are influenced by a variety of factors, including access to healthcare and socioeconomic status, rather than race itself.
Choice B reason:
Having multiple sexual partners significantly increases the risk of contracting sexually transmitted infections (STIs) like chlamydia because it raises the likelihood of exposure to an infected partner.
Choice C reason:
While being male is not a risk factor in itself, men who have sex with men (MSM) are at a higher risk for STIs like chlamydia due to biological and behavioral factors that facilitate transmission.
Choice D reason:
Engaging in sexual activities with men is a known risk factor for chlamydia among MSM due to the higher prevalence of this STI within this group.
Choice E reason:
The age of 37 does not specifically contribute to the risk of chlamydia. However, chlamydia is more commonly diagnosed in younger individuals, typically those under 25 years old, due to higher rates of new and multiple sexual partnerships.
Correct Answer is D
Explanation
Choice A reason:
Pneumothorax, a collapsed lung, can indeed cause shortness of breath and dyspnea. However, it is typically associated with a sudden onset of these symptoms following a chest injury or spontaneously in the case of a ruptured air blister. In the context of a femoral head fracture, pneumothorax is less likely unless there was additional trauma to the chest area.
Choice B reason:
Pneumonia is an infection of the lungs that leads to inflammation of the air sacs, causing them to fill with fluid or pus. Symptoms include cough with phlegm, fever, chills, and difficulty breathing. While pneumonia could cause dyspnea, it usually develops due to an infectious process rather than directly from a femoral head fracture.
Choice C reason:
Airway obstruction involves a blockage that prevents air from passing freely to the lungs. It can be caused by foreign objects, swelling due to allergic reactions, or other medical conditions. The symptoms of airway obstruction include difficulty breathing, wheezing, and potential changes in skin color. However, airway obstruction is not commonly a direct complication of a femoral head fracture.
Choice D reason:
Fat embolism syndrome is a serious condition that occurs when fat globules enter the bloodstream and lodge within the pulmonary vasculature, leading to respiratory distress. It is a known complication following long bone fractures, such as the femur, and presents with symptoms like shortness of breath, hypoxemia, and neurological manifestations. Given the recent femoral head fracture and the symptoms reported, fat embolism syndrome is the most likely diagnosis.
