What is the purpose of using a splint for a patient's injured limb?

Correct Answer: A

Rationale: A splint immobilizes an injured limb to stabilize fractures or sprains, reducing movement that could worsen damage or pain, and promoting healing. Exerting pressure isn't its role compression bandages do that if needed. Encouraging joint movement contradicts immobilization's purpose; it's about rest, not exercise. Hiding the injury isn't practical or relevant it's a medical tool, not a cover. Nurses apply splints to protect the injury site, ensuring proper alignment and safety until further treatment, a key step in acute care management.

Correct Answer: C

Rationale: Elevating the arm with a new cast reduces swelling by aiding venous return, easing pressure inside the cast for comfort and preventing complications like compartment syndrome. Using the arm normally risks damage or delayed healing. Pressing the cast can worsen pain or shift fractures. Keeping it moist invites skin breakdown or infection casts must stay dry. Nurses use pillows for elevation, monitor circulation, and educate on care, balancing comfort with healing safety in early cast stages.

Correct Answer: C

Rationale: Explaining the process and providing privacy during a bed bath promotes comfort by reducing anxiety and preserving dignity, key for a vulnerable patient. Cold water chills, not invigorates, causing discomfort in a controlled setting. Extremely hot water risks burns, especially with impaired sensation. Limiting soap doesn't save resources meaningfully and compromises cleanliness. Nurses use warm water, curtains, and clear communication to make this intimate task soothing and respectful, enhancing physical and emotional well-being.

Correct Answer: C

Rationale: Using a non-slip mat or surface prevents slipping on a wet floor, enhancing safety for a walker-assisted patient by providing traction underfoot. Walking quickly increases momentum, risking falls. Leaning backward unbalances, pulling against the walker's support. Removing the walker strips stability, heightening danger. Nurses ensure dry, grippy paths or add mats, guiding slowly, to secure ambulation, a practical fix for environmental hazards in mobility care.

Correct Answer: C

Rationale: A walker with wheels provides stability during ambulation by offering rolling support, easing movement for patients with weakness while maintaining balance. Faster walking isn't the aim safety trumps speed. Limiting mobility contradicts its purpose; it aids, not restricts. Replacing a wheelchair doesn't fit it's for walking, not sitting. Nurses adjust height and teach use, ensuring smooth, secure steps, a practical aid for gradual mobility improvement in rehabilitation or chronic conditions.
