ATI Med Surg Exam 1A Questions
Question 1 of 5
A nurse is preparing to administer Ringer's lactate 500 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 56
Rationale:
Total drops = 500 mL × 20 gtt/mL = 10,000 gtt. Infusion time = 3 hr × 60 min = 180 min. Rate = 10,000 / 180 ≈ 55.6, rounded to 56 gtt/min.
Question 2 of 5
A nurse is reviewing the laboratory results of a client who has fluid volume deficit. The nurse would expect which of the following findings?
Correct Answer: A
Rationale: Urine specific gravity of 1.035 indicates concentrated urine, consistent with fluid volume deficit.
Question 3 of 5
A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Correct Answer: 125
Rationale: Divide 1000 mL by 8 hr: 1000 / 8 = 125 mL/hr.
Question 4 of 5
A nurse is caring for four hospitalized clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?
Correct Answer: D
Rationale: Gastroenteritis and fever cause fluid loss through vomiting, diarrhea, and sweating, increasing the risk of fluid volume deficit.
Question 5 of 5
A nurse is reviewing a client's laboratory values and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?
Correct Answer: B
Rationale: Sodium polystyrene sulfonate treats hyperkalemia by exchanging sodium for potassium in the intestines, reducing blood potassium levels.
