Extract:
Question 1 of 5
A nurse is collecting data from a client who has a calcium level of 12 mg/dL (9-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: B
Rationale: Hypercalcemia depresses neuromuscular function, leading to decreased deep tendon reflexes.
Question 2 of 5
A nurse is planning to monitor a client for dehydration following several episodes of vomiting and an increase in the client's temperature. Which of the following findings should the nurse identify as an indication that the client is dehydrated?
Correct Answer: A
Rationale: High urine specific gravity (1.034) indicates concentrated urine, a sign of dehydration as the kidneys conserve water.
Question 3 of 5
A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L (3.5 -5 mEq/L). The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Correct Answer: C
Rationale: Hyperkalemia can cause life-threatening cardiac dysrhythmias, necessitating an ECG to monitor for abnormalities.
Question 4 of 5
A nurse is preparing to administer dextrose 5% in water (DSW) 100 mL to infuse over 1 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: B
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 100 mL / 60 min × 15 gtt/mL = 25 gtt/min.
Question 5 of 5
The nurse is caring for a group of patients. Which patient is at highest risk for hypovolemia?
Correct Answer: A
Rationale: Significant blood loss (2 liters) during surgery poses the highest risk for hypovolemia, requiring immediate fluid replacement.
