Question 5 of 5
A client with chronic kidney disease (CKD) arrives at the emergency department reporting shortness of breath upon exertion. What should the nurse assess first?
Correct Answer: A
Rationale: In a client with chronic kidney disease (CKD) experiencing shortness of breath upon exertion, the nurse should first assess blood pressure. CKD often leads to fluid overload and hypertension due to impaired kidney function, which can exacerbate pulmonary edema and cause dyspnea. Elevated blood pressure can directly contribute to cardiac workload and respiratory distress, making it a critical initial assessment. While respiratory rate, oxygen saturation, and heart rate are also important, blood pressure provides immediate insight into the underlying cause and guides subsequent interventions, such as administering antihypertensive or diuretic therapy.
