Question 1 of 5
A client has arterial blood gases drawn. The results are as follows: pH, 7.58; PaCO2, 48 mm Hg; HCO3, 44 mEq/L, Base Excess, +13 mEq/L. Which condition is indicated?
Correct Answer: C
Rationale: pH 7.58, HCO3 44, and base excess +13 indicate metabolic alkalosis (
C). PaCO2 48 is slightly elevated but not compensatory for respiratory conditions (A, B,
D).
Question 2 of 5
A client has arterial blood gases drawn. The results are as follows: pH, 7.58; PaCO2, 48 mm Hg; HCO3, 44 mEq/L, Base Excess, +13 mEq/L. Which condition is indicated?
Correct Answer: C
Rationale: pH 7.58, HCO3 44, and base excess +13 indicate metabolic alkalosis (
C). PaCO2 48 is slightly elevated but not compensatory for respiratory conditions (A, B,
D).
Question 3 of 5
The nurse is caring for a client with a diagnosis of upper GI bleeding. Which findings on physical assessment are consistent with this diagnosis?
Correct Answer: A
Rationale: Upper GI bleeding causes hypovolemia, leading to increased heart rate (
A) to compensate. Decreased heart rate (
B), increased hemoglobin (
C), and bounding pulses (
D) are inconsistent with blood loss.
Question 4 of 5
The nurse is discussing various oxygen delivery systems with a newly graduated nurse who has just begun working on the medical floor. Which statement by the student nurse indicates an understanding of the different oxygen delivery systems?
Correct Answer: C
Rationale: Non-rebreather masks require sufficient flow to keep the reservoir bag full (
C) for high FiO2. Tracheostomy collars vary (
A), venturi is high-flow but face tent/non-rebreather are not (
B), and non-rebreather is high-flow (
D).
Question 5 of 5
The nurse is caring for a client at risk for postpartum hemorrhage. Which early sign of hemorrhage should the nurse monitor for this client?
Correct Answer: C
Rationale: Restlessness (
C) is an early sign of hemorrhage due to decreased oxygen delivery. Coma (
A) and hypotension (
B) are late signs, and cool, clammy skin (
D) is less specific early on.
