Practice Question #1

spurdy2_1 — 2024-08-26 18:54:20 UTC

You enter the room of a client who is cyanotic, unresponsive, with no respiratory movement. You call the code, resuscitation efforts are begun, and someone draws blood gases a minute or two into the effort. The client's “down time” is unknown. (The nursing assistant reports checking on the patient 45 minutes before.) Which of the following blood gases are you likely to see?

a) pH 7.42, PaC0₂ 48 mmHg, HC0₃ 25 mEq/L

b) pH 7.29, PaC0₂ 62 mmHg, HCO₃ 23 mEq/L

c) pH 7.36, PaC0₂ 42 mmHg, HCO₃ 26 mEq/L

d) pH 7.49, PaC0₂ 30 mmHg, HCO₃ 35 mEq/L

Practice Question #2

spurdy2_1 — 2024-08-26 18:59:13 UTC

The client is a 57-year-old man admitted with a diagnosis of acute MI (heart attack). You apply oxygen at 4 liters per minute according to standing orders. ABGs are drawn 20 minutes later. Results are pH 7.36, PaC02 29, pO2 100, HC03 20, and Sa02 100%. You interpret that this client is:

A. Well-oxygenated with uncompensated Respiratory alkalosis

B. Hypoxemic with compensated respiratory acidosis

C. Well oxygenated with compensated metabolic acidosis

D. Hypoxemic with compensated metabolic acidosis.

Practice Question #3

spurdy2_1 — 2024-08-26 19:01:16 UTC

The nurse is providing care to client with the following laboratory values: pH – 7.30; PaCO₂ – 49 mmHg; and a normal HCO₃. Which condition should the nurse plan care for based on the current data?

A. Metabolic acidosis.

B. Metabolic alkalosis.

C. Respiratory acidosis.

D. Respiratory alkalosis.

Practice Question #4

spurdy2_1 — 2024-08-26 19:04:00 UTC

The nurse is reviewing the latest arterial blood gas results for a client with metabolic acidosis. Which result indicates that the metabolic acidosis is compensated?

A. pH 7.31

B. HCO3 20

C. PaCO2 32

D. PaCO2 48

Practice Question #5

spurdy2_1 — 2024-08-26 19:06:00 UTC

A nurse assesses a client who is experiencing an acid-base imbalance. The client’s arterial blood gas values are pH 7.34, PaO₂ 88 mm Hg, PaCO₂ 38 mm Hg, and HCO₃- 19 mEq/L. Which assessment should the nurse perform first?

A. Cardiac rate and rhythm

B. Skin and mucous membranes

C. Musculoskeletal strength

D. Level of orientation
