Correct Answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

Correct Answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.

Correct Answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

Correct Answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

Correct Answer: C
