A nurse is reinforcing teaching with a client's family about home oxygen use via nasal cannula. Which of the following statements by a family member indicates an understanding of the teaching?

The client presents with bilateral symmetrical joint stiffness affecting the wrists and shoulders, prolonged morning stiffness, fatigue, and anorexia, which are classic early manifestations of rheumatoid arthritis. Laboratory findings show a persistently elevated ESR and positive ANA, indicating ongoing systemic inflammation and autoimmune activity. These findings suggest a chronic inflammatory arthropathy rather than degenerative or metabolic joint disease, making rheumatoid arthritis the most likely developing condition.

Rationale for correct choices:

• Rheumatoid arthritis: Rheumatoid arthritis is a chronic autoimmune disorder characterized by symmetric polyarthritis, commonly affecting small joints such as the wrists. The client’s symptoms of bilateral joint stiffness lasting hours in the morning, fatigue, and loss of appetite strongly align with inflammatory arthritis rather than mechanical joint disease. The progression over six months and worsening systemic symptoms further support an autoimmune etiology. Positive ANA and elevated inflammatory markers reinforce the likelihood of rheumatoid arthritis development.

• ESR level: The erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is elevated in autoimmune and inflammatory conditions such as rheumatoid arthritis. The client’s persistently elevated ESR over time reflects ongoing systemic inflammatory activity. Although mildly elevated, the upward trend in ESR combined with clinical symptoms suggests chronic inflammation rather than transient infection or injury. This laboratory finding supports the presence of an evolving autoimmune process.

Rationale for incorrect choices:

• Fibromyalgia: Fibromyalgia is characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive symptoms without objective inflammatory or autoimmune markers. This client demonstrates laboratory evidence of inflammation, including elevated ESR and positive ANA, which are not consistent with fibromyalgia. Additionally, fibromyalgia does not cause joint swelling or prolonged morning stiffness.

• Gout: Gout is a metabolic disorder caused by uric acid crystal deposition, typically presenting as acute, episodic monoarticular joint pain, often in the great toe. This client has symmetric involvement of wrists and shoulders rather than isolated joint attacks. Uric acid levels are within normal limits and do not indicate hyperuricemia. The chronic progressive pattern and autoimmune markers further exclude gout as the most likely condition.

• Osteoarthritis: Osteoarthritis is a degenerative joint disease characterized by cartilage wear and typically worsens with activity rather than prolonged morning stiffness. It commonly affects weight-bearing joints and distal interphalangeal joints, not typically symmetrical small joint involvement with systemic symptoms. The presence of fatigue, elevated ESR, and positive ANA is inconsistent with a purely degenerative process.

• Diuretic medication: While diuretics can contribute to gout by increasing uric acid levels, the client’s uric acid is within normal range and does not support a metabolic cause of joint disease. There is no clinical evidence linking diuretic use to the symmetric inflammatory arthritis pattern observed here. The progression of symptoms and autoimmune lab markers point toward rheumatoid arthritis rather than medication-induced joint issues.

• Family history: A family history of hypertension, hypercholesterolemia, stroke, and stomach cancer does not specifically increase risk for rheumatoid arthritis. While genetics may play a role in autoimmune conditions, no direct familial pattern of rheumatoid disease is provided here. The more relevant indicator is the presence of inflammatory markers and positive ANA. Therefore, family history is not the strongest predictor in this scenario.

• Uric acid level: The client’s serum uric acid levels are 6.1 mg/dL and 6.3 mg/dL, which sit perfectly within the normal reference range of 2.7 to 7.3 mg/dL. Normal uric acid levels effectively rule out hyperuricemia and the metabolic conditions associated with it, meaning this laboratory parameter provides absolutely no objective evidence of an active arthropathy. Uric acid levels are entirely unrelated to the systemic inflammation, anemia of chronic disease, or positive autoantibody titers observed in this client's medical record.

Wandering behavior in clients with Alzheimer's disease poses a severe safety risk, frequently leading to falls, exposure to extreme weather, and getting lost. This behavior is often driven by confusion, a search for a familiar place, or an unmet physical need. Because clients with progressive cognitive decline lose the capacity to recognize environmental hazards, nursing interventions focus on modifying the home environment to secure exits without causing excessive agitation or restricting the client's physical freedom.

Rationale:

A. Installing complex locks at the top of all doors is the correct instruction to include. Clients with Alzheimer's disease tend to lose their complex problem-solving abilities, making specialized or double-locked mechanisms difficult for them to navigate. Furthermore, as the disease progresses, a client's visual field often narrows downward, causing them to miss things outside their direct line of sight. Placing locks high up near the top of the door frame keeps them out of the client's natural field of vision, effectively preventing them from opening external doors and wandering outside unattended.

B. Wearing a removable medical alert bracelet is an incorrect choice. While a medical identification bracelet is essential for ensuring a wandering client can be safely identified and returned home if they get lost, the bracelet must not be removable. A client with cognitive impairment can easily take off a removable bracelet, rendering it useless during an emergency. Instead, the family should utilize a permanent, non-removable ID bracelet or a secure tracking device.

C. Limiting physical activity during the day is an incorrect intervention. Restricting movement or forcing sedentariness can increase frustration, anxiety, and restlessness, which frequently exacerbates wandering behavior and sundowning (increased confusion and agitation in the late afternoon or evening). To promote better sleep patterns and reduce restless wandering, the family should encourage structured, safe physical activities during daylight hours, such as guided walks or simple household tasks.

D. Obtaining a hospital bed with side rails to use at night is an incorrect and unsafe instruction. Using full side rails on a bed for a client with cognitive impairment acts as a physical restraint. If a client with Alzheimer's disease decides to get out of bed while the rails are up, they will often attempt to climb over them. This significantly raises their center of gravity, exponentially increasing the risk of a dangerous fall from a greater height and causing severe injuries.
