When documenting a musculoskeletal assessment, which of the following descriptions correctly indicates a muscle strength rating of 4/5?
Full range of motion against gravity only
Muscle contraction visible but no movement of the joint
Full range of motion against gravity with some resistance
Full range of motion against gravity with full resistance
The Correct Answer is C
Choice A reason: Full range of motion against gravity only corresponds to a 3/5 muscle strength rating, indicating the muscle can move the joint against gravity but not additional resistance. This is weaker than 4/5, which includes some resistance, making this choice incorrect for the described strength level.
Choice B reason: Visible muscle contraction without joint movement indicates a 1/5 rating, reflecting minimal strength, often seen in severe neurological or muscular disorders. This is far below a 4/5 rating, which requires full range of motion and resistance, making this choice irrelevant to the question.
Choice C reason: A 4/5 muscle strength rating indicates full range of motion against gravity with some resistance, but not maximal. This reflects good muscle function, slightly below normal, often due to minor injury or fatigue. It aligns with standard muscle strength scales, making it the correct choice.
Choice D reason: Full range of motion against gravity with full resistance corresponds to a 5/5 rating, indicating normal muscle strength. This is stronger than 4/5, which involves only some resistance, reflecting a slight deficit. This choice does not match the described strength level.

Correct Answer is A
Explanation
Choice A reason: Assessment in the nursing process involves collecting subjective and objective data via interviews, physical exams, and observations to inform clinical judgments. This foundational step identifies patient needs, guiding subsequent planning. Accurate data collection ensures comprehensive care, preventing oversight of critical health issues and supporting effective diagnosis and intervention in clinical practice.
Choice B reason: Using problem-solving to prioritize outcomes and develop interventions describes the planning step, not assessment. Assessment focuses on data collection, not goal-setting. Assuming this misaligns with the nursing process, risking premature intervention without thorough data, which could lead to ineffective care plans or missed health issues in patient management.
Choice C reason: Assessing goal effectiveness and adjusting interventions pertains to the evaluation step, not assessment. Assessment gathers data to identify needs, not evaluate outcomes. Misidentifying this risks skipping data collection, leading to incomplete assessments and inappropriate interventions, compromising patient safety and care quality in the nursing process.
Choice D reason: Using clinical judgment to formulate problems is part of diagnosis, not assessment. Assessment collects raw data, while diagnosis analyzes it to identify issues. Assuming this conflates steps, risking incomplete data collection, which could result in inaccurate diagnoses and ineffective care plans, undermining the systematic approach of the nursing process.
Correct Answer is B
Explanation
Choice A reason: Palpating tender areas first may cause patient discomfort and guarding, reducing assessment accuracy. Palpation uses the palmar side or finger pads, starting with non-tender areas. Assuming this risks poor technique, potentially missing subtle findings like masses or edema, critical for comprehensive physical assessment in clinical practice.
Choice B reason: Palpation uses the palmar side of the hands or finger pads for light or deep touch to assess texture, tenderness, or masses. This technique ensures sensitivity and accuracy, detecting abnormalities like organ enlargement or fluid accumulation. Proper palpation is essential for thorough physical exams, guiding diagnosis and care planning effectively.
Choice C reason: Short, quick taps define percussion, not palpation, which involves sustained touch to assess underlying structures. Confusing these techniques risks incorrect assessment, missing findings like organ size or tenderness. Palpation’s distinct method using finger pads ensures accurate detection, critical for identifying abnormalities in physical examinations.
Choice D reason: Using a stethoscope is for auscultation, not palpation, which relies on manual touch with finger pads or palms. Assuming stethoscope use misaligns with palpation’s purpose, risking incomplete assessment of tactile findings like masses or swelling, essential for accurate diagnosis and effective patient care planning.
