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.

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).

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.

Correct Answer: A

Rationale: Right-sided heart failure often results from pulmonary hypertension, increasing resistance in lung circulation, unlike aortic stenosis, mitral regurgitation, or left ventricular issues.

Correct Answer: B

Rationale: Bronchodilators (e.g., albuterol) relax bronchial smooth muscles, opening airways and improving oxygenation in bronchospasm, unlike antibiotics, diuretics, or antihypertensives.
