A nurse is developing a client education program about osteoporosis for older adult clients.

The nurse should include which of the following variables as a risk factor for osteoporosis?

- A. This choice is incorrect because an older adult client who reports constipation of 4 days is not an urgent situation that requires immediate attention. The nurse should assess the client's hydration status, bowel habits, and medication use, and provide education on dietary and lifestyle modifications to prevent constipation.

- B. This choice is incorrect because a preschooler who has a skin rash is not an urgent situation that requires immediate attention. The nurse should assess the type, location, and distribution of the rash, as well as any history of allergies, exposure, or infection, and provide appropriate treatment and education.

- C. This choice is incorrect because an adolescent who has a closed fracture is not an urgent situation that requires immediate attention. The nurse should assess the site of injury, neurovascular status, pain level, and immobilization device, and provide analgesia and education on fracture care.

- D. This choice is correct because a middle adult client who has unstable vital signs is an urgent situation that requires immediate attention. The nurse should assess the client's level of consciousness, airway, breathing, circulation, and possible causes of instability, and initiate lifesaving interventions.

Choice A rationale:

Hyperthyroidism is not a contraindication for niacin use. Niacin is used to lower LDL cholesterol levels and has no specific contraindications related to thyroid disorders.

Choice B rationale:

Asthma is not a contraindication for niacin use. Niacin does not interact with asthma medications or worsen asthma symptoms, so it is not contraindicated in individuals with asthma.

Choice C rationale:

High blood pressure is not a contraindication for niacin use. In fact, niacin can help lower blood pressure and improve overall cardiovascular health. It is often prescribed to individuals with high blood pressure and elevated cholesterol levels.

Choice D rationale:

Active liver disease is a contraindication for niacin use. Niacin can cause liver damage, and individuals with active liver disease should avoid niacin therapy to prevent further harm to the liver. Monitoring liver function tests is crucial in patients taking niacin to ensure their liver health.
