When assessing the noise level that clients are exposed to, the nurse is aware that levels below which of the following number of decibels is usually safe in terms of hearing?

Correct Answer: A

Rationale: Noise levels below 85 decibels are generally safe for hearing, per occupational and health standards. Prolonged exposure above this like 95 or higher risks damage, while 110 or 120 is immediately harmful. Nurses assess this to protect clients, especially in hospitals where equipment or activity might elevate levels. Maintaining a quiet environment below 85 supports healing and prevents auditory stress, a key environmental consideration in care.

Correct Answer: A

Rationale: A washcloth in the sink prevents denture damage if dropped, best for safety. Pulling by the clasp, hot water, or overnight soaking risks harm. Nurses ensure this for equipment care.

Correct Answer: A

Rationale: Carbohydrates like grains form the food pyramid base, recommended most for energy, over vegetables, dairy, or proteins. Nurses teach this for balanced diets.

Correct Answer: B

Rationale: Assisting with passive range of motion exercises promotes mobility in a bedridden patient by maintaining joint flexibility and preventing stiffness, countering immobility's effects. Staying in bed or restricting movement worsens deconditioning, and restraints hinder progress. Nurses implement this to gradually restore function, supporting circulation and muscle health, a vital step toward active mobility in prolonged rest scenarios.

Correct Answer: D

Rationale: A CPAP mask (D) is most appropriate for sleep apnea, delivering constant pressure to keep airways open, improving oxygenation and sleep quality. Nasal cannula (A), Venturi (B), and non-rebreather (C) don't provide pressure support. CPAP is the gold standard, per sleep medicine, addressing apnea effectively.
