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 is monitoring a client who has dehydration and is receiving IV fluid replacement. Which of the following findings should the nurse identify as effectiveness of the treatment?

Question 4 of 5
A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L (3.5-5 mEq/L). Which of the following physiological responses should the nurse expect related to the client's hypokalemia?
Correct Answer: A
Rationale: Hypokalemia can impair cardiac muscle function, leading to potentially life-threatening cardiac dysrhythmias.
Question 5 of 5
A nurse is assisting with the care of a client who is hypovolemic due to blood loss following a motor-vehicle crash and needs a blood transfusion immediately. The nurse should anticipate a prescription for which of the following IV solutions while awaiting blood from a type and cross-match?
Correct Answer: B
Rationale: Lactated Ringer's, an isotonic solution, restores fluid volume and electrolytes, making it suitable for hypovolemic shock while awaiting blood.
