What is the primary purpose of a urinary catheter?

Correct Answer: B

Rationale: A urinary catheter's primary purpose is to collect urine for analysis or drainage when a patient can't void naturally, aiding diagnosis or relieving retention. Medication administration isn't its role IVs or oral routes handle that. Blood pressure measurement uses cuffs, not catheters. Breathing assistance relates to respiratory devices, not urinary ones. Nurses insert catheters to monitor output, assess kidney function, or manage incontinence, making urine collection the core function in clinical practice, critical for patient assessment and care planning.

Correct Answer: C

Rationale: Keeping the environment clutter-free promotes safety for a visually impaired patient by minimizing trip hazards and easing navigation, critical for preventing falls. Frequent furniture rearrangement disorients, increasing risk. Dark floors obscure edges, making obstacles harder to spot contrast helps. Loud music distracts, not aids, safety. Nurses ensure clear pathways and consistent layouts, often adding tactile guides, to support safe mobility and independence, tailoring the space to the patient's sensory needs effectively.

Correct Answer: C

Rationale: Using simple, clear language and allowing comprehension time promotes effective communication with a cognitively limited patient by matching their processing ability, reducing confusion, and encouraging understanding. Complex terms overwhelm, hindering accuracy. Rapid speech outpaces their grasp, causing frustration. Minimal communication isolates, missing care opportunities engagement matters. Nurses repeat key points, use visuals if needed, and check responses, patiently bridging cognitive gaps to ensure instructions or comfort are conveyed effectively.

Correct Answer: C

Rationale: A cooling fan improves sleep quality and comfort for a bedridden patient by circulating air, reducing heat and sweat, common discomforts in prolonged stillness. Warm air circulation counters this goal cooling is key. Noise might stimulate but disrupts sleep, not enhances it. Decreasing ventilation traps heat and odors, worsening conditions. Nurses position fans safely, avoiding drafts on wounds, to create a soothing environment, aiding rest and recovery, a simple comfort boost in confined settings.

Correct Answer: C

Rationale: Using a swab to clean the mouth assists a mobility-limited patient by providing gentle, effective oral care tailored to their physical constraints, preventing decay or infection. Doing it entirely for them may work but reduces autonomy unnecessarily. Leaving with tools assumes ability they may lack, risking neglect. Avoiding care invites complications discomfort stems from poor hygiene, not care itself. Nurses swab gently, often with solutions, supporting independence where possible, a practical hygiene solution for dependent patients.
