Correct Answer is A

Explanation

A. Obtain vital signs: Dizziness and lightheadedness during dialysis suggest hypotension, a common complication. The nurse should first assess vital signs to determine the severity before taking further action.

B. Bolus the client with 1000 mL of normal saline: If the client is hypotensive, a smaller fluid bolus (e.g., 250–500 mL) would be more appropriate.

C. Turn off the dialysis machine immediately: Stopping dialysis abruptly may cause fluid overload and other complications. The rate may need adjustment but not immediate cessation.

D. Notify the health care provider as soon as possible: While important, assessing the client’s current status is the priority before contacting the provider.

A. Abdomen rigid with decreased bowel sounds B. Glucose 220mg/d C. No dialysis for 24 hours D. Crackles throughout the lungs E. WBC 17,000 mm3 F. Hemoglobin 10g/dL G. Potassium 7mEq/L H. Creatinine 3 mg/dL

Correct Answer is ["A","B","D","E","G"]

Explanation

A. Abdomen rigid with decreased bowel sounds: A rigid, tender abdomen suggests peritonitis, a life-threatening complication of peritoneal dialysis requiring immediate intervention.

B. Glucose 220 mg/Dl: Elevated glucose is concerning but not immediately life-threatening compared to the other findings.

C. No dialysis for 24 hours: Missing dialysis leads to toxin accumulation, hyperkalemia, and fluid overload, all of which can be life-threatening.

D. Crackles throughout the lungs: Fluid overload can cause pulmonary edema, leading to respiratory distress. Immediate intervention is needed to prevent respiratory failure.

E. WBC 17,000 mm³: Leukocytosis suggests infection, possibly peritonitis, which requires urgent antibiotic therapy.

F. Hemoglobin 10 g/dL: Mild anemia is expected in CKD and not an emergency.

G. Potassium 7 mEq/L: Severe hyperkalemia is a medical emergency due to the risk of life-threatening cardiac arrhythmias.

H. Creatinine 3 mg/dl: Creatinine is chronically elevated in CKD and not an acute concern.
