Question 1 of 5
A nurse in a community clinic is collecting data from a client who reports frequent vomiting and diarrhea for the past 3 days. Which of the following findings should the nurse expect? (Select all that apply.)
Correct Answer: C,D,E
Rationale: Poor skin turgor, hypotension, and flat neck veins are expected findings in dehydration due to fluid loss from vomiting and diarrhea.
Question 2 of 5
A nurse reviewing the laboratory of a client who had a total thyroidectomy discovers that his calcium level is 7 mg/dL (9-10.5 mg/dL). Which of the following client findings should the nurse expect?
Correct Answer: C
Rationale: Hypocalcemia, common post-thyroidectomy, can cause muscle tetany due to increased neuromuscular excitability.
Question 3 of 5
A nurse is preparing to administer lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?(Round to the nearest whole number.)
Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
Question 4 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.

A nurse is reviewing the medical record of a client and identifies a serum potassium 6.8 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect to administer?
Correct Answer: C
Rationale: Sodium polystyrene (Kayexalate) treats hyperkalemia by exchanging sodium for potassium in the intestines, promoting potassium elimination, suitable for a dangerously high potassium level of 6.8 mEq/L.
