Question 3 of 5
A patient's arterial blood gas (ABG) results include a pH of 7.32, a PaCO2 of 56 mm Hg, and an HCO3 of 24 mEq/L. Which acid-base imbalance would the nurse use when developing the patient's plan of care?
Correct Answer: C
Rationale: Respiratory acidosis is characterized by low pH (7.32) and high PaCO2 (56 mm Hg), with normal HCO3 indicating no metabolic compensation.
Question 4 of 5
Which instruction would the nurse include in the teaching plan for a patient newly diagnosed with microcytic hypochromic anemia?
Correct Answer: C
Rationale: Taking iron with orange juice 1 hour before meals enhances absorption due to vitamin C, optimal for treating microcytic hypochromic anemia.
Question 5 of 5
Which arterial blood gas (ABG) data corresponds with a patient's clinical manifestations of respiratory alkalosis?
Correct Answer: D
Rationale: Respiratory alkalosis is indicated by a high pH (7.52) and low PaCO2 (24 mm Hg), as seen in option D, with normal HCO3 indicating no metabolic compensation.
