Based on the diagnosis of Dehydration, select which IV solution will be ordered to treat waiting this patient.
5% dextrose in Lactated ringers
0.45% sodium chloride
0.9 Sodium chloride
3% Normal Saline
The Correct Answer is C
0.9% Sodium chloride is a balanced isotonic solution that closely resembles the electrolyte composition of the extracellular fluid. It is commonly used to treat dehydration because it helps restore fluid volume and electrolyte balance in the body.
5% dextrose in Lactated Ringers: This solution is typically used for fluid and electrolyte replacement in patients who have significant fluid losses or imbalances, but it may not be the best choice for dehydration alone.
0.45% sodium chloride: This solution, also known as half-normal saline, has a lower concentration of sodium chloride and is often used for patients who require hypotonic fluids. It may not provide enough electrolyte replacement for a dehydrated patient. 3% Normal Saline: This solution has a higher concentration of sodium chloride and is typically used for specific indications, such as severe hyponatremia or in critical care settings. It is not the first-line choice for treating dehydration.

Correct Answer is D
Explanation
Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications commonly used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the production of prostaglandins, which are substances in the body that play a role in pain and inflammation. Celecoxib specifically belongs to the subclass of NSAIDs known as selective COX-2 inhibitors, which target the enzyme cyclooxygenase-2 (COX-2). By selectively inhibiting COX-2, celecoxib helps to reduce inflammation and pain while potentially minimizing the gastrointestinal side effects associated with traditional non-selective NSAIDs.

Explanation
The normal physiological changes of aging that the nurse can expect in an older adult during a musculoskeletal assessment include:
● Widened Gait: With age, there can be a natural widening of the gait due to changes in balance and stability.
● Kyphosis: Kyphosis refers to an increased curvature of the thoracic spine, commonly known as a "hunchback" appearance, which can occur due to changes in the vertebral bones and intervertebral discs.
● Slowed movement: Older adults may experience a natural decline in their movement speed due to changes in muscle strength, coordination, and reaction time. ● Muscle atrophy: Age-related muscle atrophy, or loss of muscle mass, can occur, particularly if the older adult leads a sedentary lifestyle or has other underlying health conditions.
● Decreased joint ROM (Range of Motion): Older adults may experience a gradual decrease in joint flexibility and range of motion due to changes in the joints, ligaments, and surrounding tissues. This can affect their ability to move joints fully.
It's important to note that while some older adults may develop arthritis, it is not considered a normal physiological change of aging. Arthritis refers to the inflammation and degeneration of joints, which can occur due to various factors, including age, genetics, and lifestyle.
