A nurse is teaching an older adult client who has osteoporosis about ways to promote musculoskeletal health. Which of the following instructions should the nurse include?

Choice A rationale:
Papilledema refers to swelling of the optic disc in the eye, which can occur due to increased intracranial pressure. While it may be present in cases of basilar skull fracture, it is not a reliable finding for determining the discharge of cerebrospinal fluid (CSF).
Choice B rationale:
The halo sign is a reliable finding for determining that the nasal discharge is cerebrospinal fluid. The halo sign is characterized by a ring of blood surrounded by a clear or yellowish fluid (CSF) on a dressing or tissue. This occurs because blood from the fracture mixes with the clear CSF, creating a distinct appearance.
Choice C rationale:
Racoon's eyes, also known as periorbital ecchymosis, is a term used to describe bruising around the eyes. While it can be seen in basilar skull fractures, it is not specific to cerebrospinal fluid leakage and, therefore, not reliable for identifying the nasal discharge as CSF.
Choice D rationale:
Elevated white blood cells (WBCs) in the nasal discharge can indicate infection, inflammation, or an immune response. However, it does not provide direct evidence that the discharge is cerebrospinal fluid, so this is not a reliable finding for determining the nature of the nasal discharge in this context.

Choice A rationale:
Allergy to eggs is not a contraindication for taking chondroitin with glucosamine. These supplements do not contain eggs and are generally safe for individuals with egg allergies.
Choice B rationale:
Hypotension is not directly related to the use of chondroitin with glucosamine. These supplements are not known to cause significant changes in blood pressure.
Choice C rationale:
History of hypoglycemia is not a specific concern with chondroitin and glucosamine supplements. These supplements do not significantly impact blood sugar levels in people without diabetes.
Choice D rationale:
The correct choice. The nurse should instruct the client to use chondroitin with glucosamine with caution if they are on anticoagulant therapy. Chondroitin and glucosamine may have mild anticoagulant effects, and when combined with prescribed anticoagulant medications, there is a potential risk of increased bleeding or altered blood clotting times. It is essential to monitor the client's coagulation parameters closely if they decide to use these supplements.
