Nurse 130 Final Review Questions and Correct Answers

To evaluate a client for hypoxia, the physician is most likely to order which laboratory test? Arterial blood gas (ABG) analysis A client is taking spironolactone (Aldactone) to control her hypertension. Her serum potassium level is 6 mEq/L. For this client, the nurse's priority should be to assess her: electrocardiogram (ECG) results A client with pancreatic cancer has the following blood chemistry profile: Glucose, fasting: 204 mg/dl; blood urea nitrogen (BUN): 12 mg/dl; Creatinine: 0.9 mg/dl; Sodium: 136 mEq/L; Potassium: 2.2 mEq/L; Chloride: 99 mEq/L; CO2: 33 mEq/L. Which result should the nurse identify as critical and report immediately? Potassium A client is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). Laboratory results reveal serum sodium level 130 mEq/L and urine specific gravity 1.030. Which nursing intervention helps prevent complications associated with SIADH? Restricting fluids to 800 ml/day Which set of arterial blood gas (ABG) results requires further investigation? pH 7.49, PaCO2 30 mm Hg, PaO2 89 mm Hg, and HCO3- 18 mEq/L Which electrolyte is a major cation in body fluid? Potassium Which solution is hypotonic? 0.45% NaCl Below which serum sodium concentration might convulsions or coma occur? 135 mEq/L (135 mmol/L) Which is the most common cause of symptomatic hypomagnesemia? Alcoholism When evaluating arterial blood gases (ABGs), which value is consistent with metabolic alkalosis? pH 7.48 A client has been diagnosed with an intestinal obstruction and has a nasogastric tube set to low continuous suction. Which acid-base disturbance is this client at risk for developing? Metabolic alkalosis A patient with a diagnosis of colon cancer has undergone a bowel resection with the creation of an ileostomy. The patient's ileostomy output has been unexpectedly high in the 2 days since surgery, and the patient's most recent blood work indicates a K+ level of 2.7 mEq/L. This potassium level should prompt the nurse to assess for which of the following physical manifestations? Fatigue, cramps, and weakness
