Extract:
Question 1 of 5
A nurse is caring for a client who has the following arterial blood gas results: HCO, 20 mEq, PaCO2 40 mm Hg and pH 7.32. The nurse recognizes the client is experiencing which of the following acid base imbalances?
Correct Answer: C
Rationale: Metabolic acidosis is indicated by a low HCO₃ level (below 22 mEq/L) and low pH, consistent with the given values.
Question 2 of 5
A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1L to infuse at 100 mL/hr. The nurse is using microtubing. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round to the nearest whole number.)
Correct Answer: 100
Rationale:
To calculate the manual IV infusion rate in drops per minute (gtt/min) when using microtubing, you can use the following formula: IV Drip Rate (gtt/min) = (Volume to be infused (mL) x Drop factor (gtt/mL)) / Time (min). Since microtubing typically has a drop factor of 60 gtt/mL, and the nurse is looking to infuse 1L (1000 mL) of solution at a rate of 100 mL/hr, the time to infuse 100 mL would be 60 minutes. Plugging these values into the formula gives: IV Drip Rate (gtt/min) = (100 mL x 60 gtt/mL) / 60 min, which simplifies to 100 gtt/min.
Question 3 of 5
A client diagnosed with hyperosmolar hyperglycemia nonketonic syndrome (HHNS) was admitted yesterday with a blood glucose level of 700 mg/dL. The clients blood glucose level is now 250 mg/dL. Which intervention should the nurse implement?
Correct Answer: B
Rationale: When blood glucose drops significantly, insulin infusion rates are usually decreased to prevent hypoglycemia and a rapid fall in glucose levels.
Question 4 of 5
A nurse is caring for a client who is postoperative following a transurethral resection of the prostate. Which of the following complications is the priority for the nurse to monitor for?
Correct Answer: C
Rationale: Hemorrhage is a serious and potentially life-threatening complication after TURP, making it the priority for monitoring in the immediate postoperative period.
Question 5 of 5
A nurse is caring for a client who had total thyroidectomy and a serum calcium level of 7.6 mg/dL. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: Tingling of the extremities, known as paresthesia, is a common symptom of hypocalcemia, which can occur after thyroidectomy due to potential damage or removal of the parathyroid glands.
