A client presents with a temperature of 38°C (100.4°F) and a stiff neck. Which condition should the nurse suspect?

Choice A rationale
Urine specific gravity of 1.029 indicates concentrated urine, which is common in dehydration but not specific to prerenal AKI. It reflects the kidney’s ability to concentrate urine in response to fluid deficit.
Choice B rationale
BUN of 28 mg/dL can indicate dehydration or renal impairment. However, it is not as specific as creatinine in diagnosing prerenal AKI. BUN can be elevated due to other factors like high protein intake or gastrointestinal bleeding.
Choice C rationale
Creatinine of 2.4 mg/dL is a critical indicator of kidney function. Elevated creatinine levels are more specific to renal impairment, including prerenal AKI, as they reflect the kidney’s ability to filter waste products.
Choice D rationale
Dry mucous membranes are a sign of dehydration but are not specific to prerenal AKI. They indicate fluid volume deficit but do not directly reflect kidney function.

Choice A rationale
A respiratory rate of 28 breaths per minute indicates tachypnea, which is a sign of respiratory distress. Immediate intervention is needed to address the underlying cause and prevent further deterioration of the patient’s condition.
Choice B rationale
A temperature of 38°C (100.4°F) indicates a fever, which may suggest an infection. While this requires medical attention, it is not as immediately critical as respiratory distress.
Choice C rationale
A blood pressure of 140/90 mmHg is considered high, but it does not indicate an immediate need for intervention in the context of COPD. Hypertension should be managed, but it is not an acute emergency.
Choice D rationale
A heart rate of 90 beats per minute is within the normal range and does not indicate an immediate need for intervention. Monitoring the patient’s heart rate is important, but it is not an urgent concern in this scenario.
