A charge nurse is mentoring a newly licensed nurse about ergonomic principles. Which of the following should the charge nurse include when teaching about ergonomic principles?
Raise the head of the bed when transferring a client from a bed to a stretcher.
Place pillows underneath the client’s head when repositioning a client in bed.
Use a lateral transfer device when moving a client from a bed to a stretcher.
Stand close to the client when assisting with ambulation.
The Correct Answer is C
Choice A reason: Raising the head of the bed during transfer does not prioritize ergonomic principles. It may strain the nurse’s back or misalign the client, increasing injury risk. Ergonomics focuses on neutral spine alignment and mechanical aids to reduce physical strain during client transfers.
Choice B reason: Placing pillows under the head is a comfort measure, not an ergonomic principle. Ergonomics emphasizes reducing musculoskeletal strain through proper mechanics or devices. Pillows do not directly prevent nurse injuries, unlike transfer devices that minimize physical effort during client movement.
Choice C reason: Using a lateral transfer device, like a slide board, aligns with ergonomic principles by reducing manual lifting and spinal strain. It prevents back injuries, ensuring safe client transfer. This evidence-based practice supports occupational health guidelines, minimizing musculoskeletal risks for nurses during patient handling.
Choice D reason: Standing close during ambulation ensures client stability but is not a primary ergonomic principle. Ergonomics focuses on equipment and mechanics to reduce strain, not proximity, which addresses patient safety more than nurse injury prevention during transfers or repositioning tasks.

Correct Answer is C
Explanation
Choice A reason: Placing the client in semi-Fowler’s position for postoperative assessment is appropriate, promoting lung expansion and reducing aspiration risk. This aligns with standard care, supporting respiratory function and comfort, requiring no further instruction as it reflects safe, evidence-based practice.
Choice B reason: Auscultating lungs without lifting the gown may reduce clarity but is not unsafe. It preserves modesty and is acceptable if effective. While lifting the gown is preferred, this action poses minimal risk, requiring less instruction compared to errors with immediate safety implications.
Choice C reason: Administering an enema without checking for contraindications, like bowel obstruction, risks complications such as perforation. This reflects poor assessment, necessitating instruction to ensure the nurse verifies patient safety and chart details before invasive procedures to prevent harm.
Choice D reason: Checking vital signs before cardiac medication is correct, ensuring safety (e.g., withholding beta-blockers for low heart rate). This follows pharmacological protocols, requiring no instruction, as it demonstrates competence in safe medication administration practices on a medical-surgical unit.
Correct Answer is D
Explanation
Choice A reason: Bleeding time assesses platelet function, not warfarin’s anticoagulant effect. Warfarin inhibits vitamin K-dependent clotting factors, unrelated to platelets. Monitoring bleeding time does not reflect therapeutic anticoagulation levels, making it irrelevant for adjusting warfarin doses to prevent thrombosis or bleeding.
Choice B reason: Factor VIII, deficient in hemophilia A, is not affected by warfarin, which targets vitamin K-dependent factors (II, VII, IX, X). Measuring Factor VIII does not indicate warfarin’s efficacy, as it is unrelated to the drug’s mechanism, making it unsuitable for dose monitoring.
Choice C reason: aPTT monitors heparin’s effect on the intrinsic clotting pathway, not warfarin’s action on vitamin K-dependent factors. Warfarin requires INR for therapeutic monitoring, as aPTT is insensitive to its effects, making it inappropriate for assessing warfarin’s anticoagulation range in patients.
Choice D reason: INR standardizes prothrombin time, measuring warfarin’s effect on vitamin K-dependent clotting factors. It ensures therapeutic anticoagulation (e.g., INR 2-3), preventing thrombosis or bleeding. INR is the gold standard for warfarin monitoring, guiding dose adjustments for safe and effective therapy.
