Extract:
Question 1 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?
Correct Answer: B
Rationale: Urine output of 200 mL/4 hr (50 mL/hr) indicates improved kidney perfusion and hydration, suggesting effective treatment.
Question 2 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 3 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 4 of 5
An older adult nursing home resident who has always been alert and oriented is now showing signs of dehydration and has become confused. Which electrolyte imbalance is most likely involved?
Correct Answer: C
Rationale: Hyponatremia disrupts brain cell function, commonly causing confusion in dehydrated older adults.
Question 5 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.
