A nurse at an urgent care center is reinforcing information with a new employee about the difference between sprains and strains. Which of the following examples should the nurseinclude as a cause of sprain injury?

Overusing a muscle while jogging

Twisting a ligament while walking

Impact injury on a joint from a fall

Crush injury to a bone from blunt trauma

Answer and Explanation

The Correct Answer is B

a. Overusing a muscle while jogging: Overuse injuries are more commonly associated with strains, not sprains. Strains involve the muscles or tendons.

b. Twisting a ligament while walking: This is an example of a mechanism that can lead to a sprain. A sprain involves the stretching or tearing of ligaments, which connect bone to bone.

c. Impact injury on a joint from a fall: This is more likely to result in a sprain, as it can cause damage to ligaments.

d. Crush injury to a bone from blunt trauma: This type of injury is more likely to affect bones rather than ligaments or tendons, and it would not be considered a sprain or strain.

Correct Answer is B

Explanation

a. Rest in a supine position: Resting in a supine position may compromise lung expansion, and an upright position is often recommended for clients with emphysema to improve ventilation.

b. Breathe in through her nose and out through pursed lips: This technique helps maintain

positive airway pressure, preventing premature airway collapse, and can improve gas exchange in clients with emphysema.

c. Limit fluid intake throughout the day: Adequate hydration is important for maintaining

respiratory secretions in a liquefied state and is generally encouraged for clients with respiratory conditions.

d. Consume a low-protein diet: A low-protein diet is not specifically indicated for improving gas exchange in clients with emphysema. Nutrition recommendations may focus on a well-balanced diet to support overall health.

A. Creatinine 0.9 mg/dL B. WBC count 20,000/mm3 C. Potassium 3.8 mEq/L D. Hematocrit 40%

Correct Answer is B

Explanation

a. Creatinine 0.9 mg/dL: This creatinine level is within the normal range and is not an immediate priority for knee arthroplasty.

b. WBC count 20,000/mm3: An elevated white blood cell count suggests the presence of

infection or inflammation. In the context of knee arthroplasty, infection is a significant concern and requires immediate attention to prevent complications.

c. Potassium 3.8 mEq/L: This potassium level is within the normal range and is not an immediate priority for knee arthroplasty.

d. Hematocrit 40%: This hematocrit level is within the normal range and is not an immediate priority for knee arthroplasty. The elevated WBC count takes precedence as it suggests a

potential infectious process.
