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:

Instructing the client to take deep breaths during the test is not appropriate for a thoracentesis. This procedure involves the insertion of a needle into the pleural space to drain fluid or air, and taking deep breaths could interfere with the accuracy and safety of the procedure.

Choice B rationale:

Assisting the client to a prone position prior to the test is also incorrect. During a thoracentesis, the client is usually seated upright or in a slightly forward-leaning position to allow better access to the pleural space and improve breathing.

Choice C rationale:

Informing the client that the new onset of a cough is expected following the test is not accurate. While a cough can be a possible side effect, it is not a common or expected outcome of a thoracentesis.

Choice D rationale:

Applying pressure to the client's puncture site after the test is complete is the correct action. This helps to prevent bleeding and reduce the risk of pneumothorax (collapsed lung) by promoting clot formation at the site of the needle insertion.

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.
