Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
A nurse is assessing four adult clients. Which of the following physical assessment techniques should the nurse use?
Correct Answer: B
Rationale: Ensure the bladder of the blood pressure cuff surrounds 80% of the client’s arm.
Question 2 of 5
A client at a healthcare facility is diagnosed with polyuria. How would the nurse describe the client's condition in the medical record?
Correct Answer: D
Rationale: Polyuria is excessive urine output. Inadequate (A) is retention. Absence (B) is anuria. Difficult voiding (C) is dysuria.
Question 3 of 5
A nurse is teaching staff about the conduction of the heart. In which order will the nurse present the conduction cycle, starting with the initial impulse? Bundle of His, Purkinje network, Intraventricular pathways, Sinoatrial (SA) node, Atrioventricular (AV) node
Correct Answer: B
Rationale: The cardiac conduction cycle starts at the sinoatrial (SA) node (4), the heart’s pacemaker, generating the impulse. It travels to the atrioventricular (AV) node (5), then to the Bundle of His (1), through the intraventricular pathways (3), and finally to the Purkinje network (2) for ventricular contraction. The correct sequence is 4, 5, 3, 1,
Question 4 of 5
Which process involves the movement of air into and out of the lungs?
Correct Answer: A
Rationale: Ventilation is the mechanical movement of air into and out of the lungs, distinct from perfusion (blood flow), diffusion (gas exchange), and respiration (overall oxygen use).
Question 5 of 5
A nurse is teaching a patient about improving oxygenation. Which instruction is most effective?
Correct Answer: C
Rationale: Purse-lip breathing prolongs exhalation, reducing air trapping and improving oxygenation, especially in COPD. Sleeping flat, avoiding exercise, or increasing salt don’t enhance oxygenation.
