A client with a feeding tube has developed constipation as a result of inactivity. Which nursing intervention would most likely help to resolve this complication?

Correct Answer: B

Rationale: Constipation due to inactivity is best addressed by increasing dietary fiber and fluid intake, which promote peristalsis and soften stool, even in clients with feeding tubes (via enteral formulas with fiber or additional water flushes). Securing the tube (A) prevents dislodgement but doesn’t address constipation. Monitoring blood glucose (C) is unrelated to bowel elimination. Checking residuals (D) ensures tolerance to feedings but doesn’t directly resolve constipation.

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,

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.
