A nurse is instructing a client who has cancer about precautions to take while undergoing chemotherapy. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:

A defined area of cool, boggy skin is not indicative of a stage 2 pressure injury. Stage 2 pressure injuries involve partial-thickness skin loss, usually appearing as a shallow open ulcer with a red-pink wound bed, without slough or bruising.

Choice B rationale:

A shallow crater involving the epidermis is characteristic of a stage 2 pressure injury. It presents as a partial-thickness skin loss with the loss of the epidermis, and the wound may be superficial and appear as an abrasion, blister, or shallow ulcer.

Choice C rationale:

The reddened area that does not blanch is more indicative of an early-stage pressure injury (Stage 1). In Stage 1, the skin remains intact, but there is non-blanch-able erythema indicating damage to the skin and underlying tissue.

Choice D rationale:

Undermining or tunneling of the skin is not specific to stage 2 pressure injuries. These features may be observed in more advanced stages of pressure injuries, such as stages 3 and 4, where there is full-thickness skin loss with damage to the subcutaneous tissue and underlying structures.

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.
