WGU D446 Adult Health II Objective Assessment (OA)
EXAM QUESTIONS AND 100% VERIFIED ANSWERS WITH RATIONALES
GRADED A+ LATEST
Question 1
A client with type 1 diabetes presents with polyuria, polydipsia, fruity breath, and
Kussmaul respirations. Which laboratory finding is most consistent with this
condition?
A. Blood glucose 180 mg/dL
B. Serum bicarbonate 10 mEq/L
C. Serum potassium 3.0 mEq/L
D. Arterial pH 7.42
Correct Answer: B
Rationale: Diabetic ketoacidosis is characterized by metabolic acidosis, reflected
by low bicarbonate levels. Blood glucose is typically >250 mg/dL, potassium is
often elevated initially, and pH is acidic (<7.35).
Question 2
A nurse is caring for a patient with chronic obstructive pulmonary disease (COPD).
Which oxygen saturation target is most appropriate?
A. 94–98%
B. 92–96%
C. 88–92%
D. 85–88%
Correct Answer: C
Rationale: Patients with COPD rely on hypoxic drive. Oxygen saturation should
be maintained between 88–92% to prevent respiratory depression.
