A nurse is assessing an 82-year-old client during a routine health maintenance visit. Which assessment finding would be considered a normal age-related change?

## 보기

1. Blood pressure of 180/100 mmHg
2. Decreased muscle mass and strength **✔ 정답**
3. New onset confusion and disorientation
4. Sudden weight loss of 15 pounds in one month

**정답: 2**

## 해설

Decreased muscle mass and strength (sarcopenia) is a normal age-related change, while other findings (hypertension, new confusion, sudden weight loss) indicate pathological conditions requiring intervention.

Understanding Normal Age-Related Changes vs. Pathological Findings

When assessing an older adult, distinguishing between expected physiological aging and disease processes is a fundamental nursing skill. The question asks you to identify a normal age-related change. Let's analyze each option through this lens.

Analysis of Each Option

**Option 1: Blood pressure of 180/100 mmHg**

This is a pathological finding, not a normal change. While the arterial walls naturally stiffen with age, which can lead to isolated systolic hypertension, a reading this high indicates Stage 2 hypertension or a hypertensive crisis requiring immediate intervention. It reflects cardiovascular disease, not healthy aging.

**Option 2: Decreased muscle mass and strength**

This is the correct answer. The progressive and generalized loss of skeletal muscle mass and strength is the hallmark of a condition known as sarcopenia. The provided evidence firmly establishes sarcopenia as an age-related geriatric syndrome [1]. Research on community-dwelling adults confirms that muscle health indicators decline with age, with specific inflection points that define this process [3]. This physiological change is so intrinsically linked to the aging process that studies are now establishing sex- and age-specific diagnostic cutoffs to better characterize it [3]. It is considered a primary age-related change, distinct from disease, although it can be exacerbated by factors like poor nutrition or chronic illness .

**Option 3: New onset confusion and disorientation**

This is a "red flag" finding. Acute confusion, often termed delirium, is a medical emergency in an older adult. It is never a normal part of aging and typically signals an underlying physiological cause such as infection (e.g., urinary tract infection), medication toxicity, or metabolic imbalance. It requires prompt investigation.

**Option 4: Sudden weight loss of 15 pounds in one month**

Unintentional, rapid weight loss is a major warning sign. In the geriatric population, this is a key indicator of potential malignancy, severe depression, malabsorption, or other serious chronic diseases. Research on elderly patients with chronic conditions like heart failure and cancer highlights that significant nutritional risk and malnutrition are pathological states that lead to poor outcomes, including the development or worsening of sarcopenia . This finding demands a thorough diagnostic workup, not reassurance.

Clinical Application and NCLEX-RN Focus

For the NCLEX-RN, you must be able to differentiate between expected findings (like the gradual decline in muscle strength and mass known as sarcopenia [1][3]) and abnormal findings that require immediate action. The assessment of an older adult's functional status, including muscle strength, is a key component of a routine health visit. While sarcopenia is a normal age-related change, its progression can be influenced by pathological states. For instance, the presence of nutritional risk or chronic diseases like heart failure and cancer can accelerate muscle loss and lead to a combined, more severe clinical picture with worse outcomes . Your role includes not only recognizing sarcopenia as an expected change but also screening for the modifiable risk factors, such as malnutrition, that can worsen it .References (research sources)

## 임상 시나리오

Geriatric Assessment: Normal vs. PathologicalDistinguishing Expected Aging Changes from Disease
A core nursing skill is differentiating sarcopenia, a normal age-related loss of muscle mass and strength, from pathological findings. Sarcopenia is a primary geriatric syndrome, not a disease, though it can be worsened by disuse or malnutrition.

A blood pressure of 180/100 mmHg is never normal. While arterial stiffening causes isolated systolic hypertension, this reading indicates Stage 2 hypertension or a crisis, a cardiovascular disease state.

CautionAny acute onset of confusion, disorientation, or significant unintended weight loss (e.g., 15 lbs in 1 month) is a red flag for serious underlying pathology like delirium, dementia, or malignancy and requires immediate investigation.

## 핵심 개념

- **Sarcopenia** — The progressive, age-related loss of muscle mass and strength, considered a primary physiological change in older adults.
- **Stage 2 Hypertension** — A blood pressure consistently at or above 140/90 mmHg, indicating a pathological cardiovascular condition requiring management.
- **Delirium** — An acute, fluctuating disturbance in attention and awareness, often with a medical cause, which is not a normal part of aging.
