A nurse is teaching an older adult client about reducing the risk for osteoporosis. Which of the following statements by the client indicates an understanding of the teaching?

A. Administer the PN and fat emulsion separately:

Administering the PN and fat emulsion separately is not a typical practice. Usually, PN formulations are prepared to include both macronutrients (carbohydrates and fat) in a single bag to provide a balanced nutritional profile. Administering them separately might lead to inconsistencies in the client's nutritional intake.

B. Prepare the client for a central venous line:

This is the correct action. Parenteral nutrition (PN) with a high concentration of dextrose (20%) and fat emulsions can be hypertonic and irritating to peripheral veins. Therefore, a central venous line is often recommended for the administration of such solutions. Preparing the client for a central venous line helps ensure the safe and effective delivery of PN.

C. Change the PN infusion bag every 48 hr:

The frequency of changing the PN infusion bag is not solely determined by time but rather by factors such as the stability of the solution, risk of contamination, and compatibility of the components. The specific recommendation for changing the PN bag should be based on institutional policies and the characteristics of the PN solution being used.

D. Obtain a random blood glucose daily:

While monitoring blood glucose is important in clients receiving PN, obtaining a random blood glucose daily is not specific enough for managing the potential hyperglycemic effects of a 20% dextrose solution. Continuous glucose monitoring or more frequent and scheduled blood glucose checks may be necessary.

A. "Increase intake of vitamin B12":

Vitamin B12 is important for various bodily functions, including the health of nerves and red blood cells, but it is not directly associated with osteoporosis prevention. Calcium and vitamin D are more critical nutrients for bone health.

B. "Walk for 30 minutes three to five times each week":

Weight-bearing exercises, such as walking, are beneficial for preventing osteoporosis. Weight-bearing activities stimulate bone formation and help maintain bone density. Regular walking for 30 minutes, three to five times per week, can contribute to overall bone health and reduce the risk of osteoporosis.

C. "Perform water aerobics three times each week":

While water aerobics is a beneficial exercise for cardiovascular health and joint flexibility, it is not as effective as weight-bearing exercises for preventing osteoporosis. Weight-bearing activities put stress on bones, promoting bone density.

D. "Maintain a lean body mass":

Maintaining a healthy body weight and lean body mass is important for overall health, but it is not a direct preventive measure for osteoporosis. Weight-bearing exercises and adequate intake of calcium and vitamin D are more specific recommendations for preventing osteoporosis.
