ATI Med Surg Exam 1A Questions
Extract:
Question 1 of 5
A nurse is assessing an older adult client who is receiving IV therapy. The nurse should recognize that which of the following findings indicates fluid volume excess?
Correct Answer: A,B,C
Rationale: Crackles, bounding pulse, and pitting edema indicate fluid overload; swelling at the IV site is localized, and high urine specific gravity suggests dehydration.
Question 2 of 5
A nurse is caring for a client who has metabolic alkalosis. For which of the following clinical manifestations should the nurse monitor?
Correct Answer: A,B,C,D
Rationale: Metabolic alkalosis causes lethargy, circumoral paresthesia, bicarbonate excess, and flushing due to high pH and bicarbonate levels.
Question 3 of 5
A nurse is caring for a client whose arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Correct Answer: A
Rationale: A pH of 7.3 (acidic) and PaCO2 of 50 mm Hg (elevated) indicate respiratory acidosis due to CO2 retention.
Question 4 of 5
A nurse is assessing a client who has fluid volume deficit. The nurse should expect which of the following findings?
Correct Answer: D
Rationale: Fluid volume deficit causes hemoconcentration, increasing BUN due to reduced kidney perfusion.
Question 5 of 5
A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq/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:
To determine the mL/hr rate, set up a proportion: (40 mEq / 500 mL) = (10 mEq / x mL). Cross-multiply: 40x = 5000, so x = 5000 / 40 = 125 mL/hr.
