Which musculoskeletal complication can occur due to prolonged immobility?

Correct Answer: C

Rationale: Prolonged immobility leads to osteoporosis, where bones weaken and become brittle due to reduced weight-bearing activity and mineral loss a significant risk for fractures. Muscle strength and joint flexibility decline, not improve, with disuse, and contractures become more likely as muscles shorten. Nurses combat this with range-of-motion exercises or weight-bearing support, recognizing that bone density loss is a pressing musculoskeletal threat in long-term immobility, necessitating preventive strategies to maintain skeletal health and patient mobility.

Correct Answer: B

Rationale: Securing tubing under furniture legs (B) indicates a need for education, as it risks kinking or disconnection, disrupting oxygen flow and posing a safety hazard. Avoiding smoking (A) and flames (C) are correct safety measures. Water-based moisturizer (D) is appropriate. Proper tubing management education, per safety standards, prevents accidents.

Correct Answer: C

Rationale: The Coumadin order (10 mg PO) lacks a frequency (e.g., daily), making it incomplete and requiring clarification to ensure safe anticoagulation dosing, critical due to bleeding risks. Other orders specify timing and conditions clearly Darvocet PRN, Mysoline thrice daily, Premarin daily. Nurses seek clarification to prevent errors, ensuring precise administration aligned with therapeutic goals.

Correct Answer: D

Rationale: Cimetidine, an H2 blocker, prevents gastric ulcers, a common prednisone side effect in leukemia treatment, by reducing acid production protecting the stomach during corticosteroid use. It doesn't affect pancreatic enzymes, methotrexate efficacy, or peristalsis. Nurses administer it prophylactically, educating clients on its protective role, ensuring gastrointestinal safety amid aggressive chemotherapy.

Correct Answer: C

Rationale: A sore throat on chlorpromazine (Thorazine) may signal agranulocytosis, a rare, life-threatening drop in white cells, requiring immediate physician report urgent in schizophrenia care. Thirst, weight gain, or napping are common but less acute. Nurses flag this, prompting blood counts, ensuring rapid intervention to prevent infection.
