Which of the following statement best describe infection control?

Correct Answer: B

Rationale: Infection control is preventing disease spread (B), per nursing e.g., handwashing. Not ignoring (A), not task (C), not one-time (D) ongoing prevention. B best defines its protective role, like for Mr. Gary, making it correct.

Correct Answer: B

Rationale: In nursing diagnoses, a standardized format connects the problem to its cause. The phrase 'related to' is used to link the identified health issue, such as 'Impaired Mobility,' to its etiology, like 'joint stiffness,' forming a clear cause-and-effect relationship. 'As manifested by' and 'evidenced by' describe symptoms or signs supporting the diagnosis, not the cause. 'Due to' is less specific and not part of the formal nursing diagnosis structure outlined by NANDA International. This format ensures clarity in care planning, allowing nurses to address underlying causes effectively, enhancing patient outcomes through targeted interventions based on this relationship.

Correct Answer: B

Rationale: Stage II pressure ulcers involve partial-thickness skin loss, presenting as abrasions, blisters, or shallow craters, often with edema or infection if untreated. Stage I shows non-blanchable redness, Stage III extends to subcutaneous tissue, and Stage IV reaches muscle or bone. Nurses assess these signs to stage ulcers accurately, guiding interventions like pressure relief or wound care, preventing progression and promoting healing in at-risk patients.

Correct Answer: C

Rationale: Vitamin C is essential for collagen synthesis, a key wound healing component, strengthening tissue repair. Vitamin A supports epithelial growth, Vitamin K aids clotting, and B complex boosts energy, but collagen formation is primary. Nurses ensure adequate C intake (e.g., citrus), accelerating recovery, preventing dehiscence, and supporting immune response at wound sites.

Correct Answer: D

Rationale: Effective charting requires accuracy, clarity, and accountability, adhering to legal and professional standards. Signing the medication sheet after administering medication, as Nurse Jane does, exemplifies this by confirming the intervention occurred, ensuring patient safety, and providing a verifiable record. This practice aligns with the 'Five Rights' of medication administration and reduces error risks, such as double-dosing. Conversely, signing as 'J.R.' lacks full identification (name and title), compromising accountability. Using a pencil risks erasure or alteration, undermining record integrity, as permanent ink is standard. Noting 'appetite is good' is subjective and lacks detail (e.g., meal percentage consumed), reducing its clinical value. Nurse Jane's action of signing post-medication administration reflects a strong grasp of charting's role in care continuity and safety, making it the best demonstration of effective documentation principles.
