Extract:
Question 1 of 5
The client's arterial blood gases reveal the following results: pH 7.51, PaO2 80 mmHg, PaCO2 28 mmHg, HCO3 24 mEq/L, O2 saturation 92%. The nurse interprets this blood gas result as:Table 9.9 Normal Arterial Blood Gas Values pH (7.35-7.45) PaO2 (80-95 mm Hg) PaCO2 (35-45 mm Hg) HCO3 (22-26 mEq/L) O2 saturation (>95%) Base excess -2 to +2
Correct Answer: A
Rationale: Elevated pH (7.51) and low PaCO2 (28 mmHg) indicate respiratory alkalosis, likely due to hyperventilation.
Question 2 of 5
The nurse is planning care that would decrease the risk for infection in a client who is recovering from a colectomy. The nurse would include which intervention(s)?

Correct Answer: C
Rationale: A thunderclap headache and neck stiffness are hallmark symptoms of subarachnoid hemorrhage, often due to aneurysm rupture.
Question 4 of 5
A client admitted to the Emergency Department (ED) and the cardiac monitor shows multifocal premature ventricular contractions (PVC's). Initial laboratory findings are as follows. The nurse recognizes that the client's PVC's are most likely caused by:
Correct Answer: C
Rationale: Hypokalemia (2.8 mEq/L) is a known cause of PVCs due to its effect on cardiac repolarization.
Question 5 of 5
Which of the following interventions would the nurse emphasize during education to assist the patient diagnosed with trigeminal neuralgia in managing their pain?
Correct Answer: A
