ATI LPN Med Surg Cohort 6 Exam Questions
Extract:
Question 1 of 5
A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22, PaCO2 68 mm Hg, Base excess -2, PaO2 78 mm Hg, Oxygen saturation 80%, Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?
Correct Answer: B
Rationale: Low pH and high PaCO2 indicate respiratory acidosis, likely due to hypoventilation.
Question 2 of 5
Which people have the greatest risk for serious complications secondary to herpes zoster infection? Select all that apply.
Correct Answer: B,C,E
Rationale: Immunosuppression from prednisone, chemotherapy, or HIV increases risk of severe herpes zoster complications.

Correct Answer: C
Rationale: Famotidine reduces stomach acid, helping prevent stress-induced ulcers during surgery, providing a clear and accurate explanation.
Question 5 of 5
A nurse evaluates the following arterial blood gas values in a patient: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 - 22 mEq/L (22 mmol/L). Which patient condition does the nurse correlate with these results?
Correct Answer: C
Rationale: High pH and low PaCO2 indicate respiratory alkalosis, consistent with hyperventilation from anxiety.
