Question 1 of 5
A nurse is phoning a provider to report a client's serum potassium of 6.2 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect the provider to prescribe?
Correct Answer: A
Rationale: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by lowering potassium levels through ion exchange in the intestines.
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 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 4 of 5
A nurse is phoning a provider to report a client's serum potassium of 6.2 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect the provider to prescribe?
Correct Answer: A
Rationale: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by lowering potassium levels through ion exchange in the intestines.

Which of the following solutions can be administered with a blood component?
Correct Answer: A
Rationale: 0.9% sodium chloride (normal saline) is isotonic and safe to administer with blood products, as it does not cause hemolysis.
