NURS 3100 Exam 1 Practice

A charge nurse is conducting a nutritional class for a group of newly licensed nurses regarding basal metabolic rate (BMR). The charge nurse should inform the class that which of the following factors increases BMR?

1. Age older than 60, lactation, puberty, and prolonged stress

2. Age older than 60, lactation, and puberty

3. Lactation, puberty, and malnutrition

4. Malnutrition, puberty, and prolonged stress

The correct answer is: Age older than 60, lactation, puberty, and prolonged stress

The correct answer is A because factors such as age older than 60, lactation, puberty, and prolonged stress are known to increase the basal metabolic rate (BMR). - Age older than 60: As individuals age, their BMR typically decreases. However, in individuals older than 60 years old, BMR can increase due to various factors such as hormonal changes and decreased muscle mass. - Lactation: Breastfeeding requires additional energy expenditure, thus increasing the BMR to support the production of breast milk. - Puberty: During puberty, the body undergoes significant growth and development, which can lead to an increased BMR. - Prolonged stress: Stress can cause an increase in the production of certain hormones like cortisol, which can raise the BMR as the body responds to the stressor. The other options are not correct because they do not include all the factors that are known to increase BMR.
