A nurse is performing a health screening for a client who weighs 90 kg (198 lb) and is 160 cm (63 in) tall. The nurse should classify the client's BMI as falling into which of the following categories?

Overweight

Extremely obese

Normal

Obese

Answer and Explanation

The Correct Answer is D

To calculate the BMI:

Convert weight to kilograms: 90 kg (198 lb)
Convert height to meters: 160 cm = 1.6 m
Use the BMI formula: BMI = weight (kg) / height (m)^2

BMI = 90 / (1.6)^2 BMI = 90 / 2.56 BMI ≈ 35.2

A. Overweight: Overweight is typically classified with a BMI from 25 to 29.9. This BMI is higher.
B. Extremely obese: The term "extremely obese" is not commonly used. The classification for a BMI above 40 would be "extremely obese."
C. Normal: A normal BMI ranges from 18.5 to 24.9. The calculated BMI is higher than this range.
D. Obese: A BMI of 35.2 falls into the category of obesity (30 to 39.9).

Correct Answer is A

Explanation

A. Uses a paper towel to turn the water off after washing hands: This is correct practice. Using a paper towel to turn off the faucet helps prevent recontamination of hands after handwashing.
B. Uses a respirator mask when bathing a client who has hepatitis A: This is incorrect. Hepatitis A is transmitted through fecal-oral contact, not airborne. Standard precautions, such as using gloves and hand hygiene, are appropriate, but a respirator is not necessary.
C. Keeps artificial fingernails trimmed short: While keeping fingernails trimmed is important for infection control, artificial nails are not recommended in healthcare settings due to the risk of harboring pathogens.
D. Shakes out soiled linen before bagging it: This is incorrect. Shaking out soiled linen can spread contaminants into the air. Soiled linen should be handled carefully and placed directly into the appropriate bag without shaking.

A. Increase dietary intake of fats. B. Reduce intake of fluids. C. Increase fiber gradually each day. D. Reduce dietary intake of probiotics.

Correct Answer is C

Explanation

A. Increase dietary intake of fats. While fats can help lubricate the intestines, increasing fat intake is not a primary recommendation for managing constipation. Focusing on fiber and fluid intake is more effective.
B. Reduce intake of fluids. Reducing fluid intake can worsen constipation. Adequate hydration is essential to soften stool and promote regular bowel movements.
C. Increase fiber gradually each day. Increasing fiber intake gradually helps prevent constipation. Fiber adds bulk to the stool and helps it move more easily through the digestive tract. A gradual increase prevents gas and bloating that can occur with a sudden high intake of fiber.
D. Reduce dietary intake of probiotics. Probiotics can actually aid in maintaining a healthy digestive system and can help with bowel regularity. Reducing them is not recommended for managing constipation.
