Correct Answer: B

Rationale: An abscess is defined as a cavity containing pus surrounded by inflamed tissue. Cellulitis is a bacterial skin infection causing redness and swelling, not a cavity. Extravasation is the leakage of fluid from a vessel into surrounding tissues, not a cavity. An adhesion is a band of scar-like tissue that binds two parts together, not a cavity containing pus and inflamed tissue.

Correct Answer: D

Rationale: The correct response is D because the health care surrogate, as designated by the client, has the legal authority to make healthcare decisions on behalf of the client when they are unable to do so. This authority includes decisions about treatment continuation or withdrawal. Option A is incorrect as the family member's wishes do not override the legal authority of the health care surrogate. Option B is not the most appropriate action in this situation as the advance directives are already clear by the designation of a health care surrogate. Option C is not necessary at this stage since the health care surrogate can make the decision without involving the ethics committee.

Correct Answer: D

Rationale: The correct action to take when a patient becomes hypotensive with a bounding, rapid pulse rate after administering penicillin intravenously is to stop the intravenous flow immediately. This can help prevent further complications by discontinuing the administration of the medication that might be causing the adverse effects. Decreasing or increasing the rate of medication flow may not address the underlying issue of the patient's adverse reaction. While it's important to involve the healthcare provider in such situations, the immediate priority is to halt the administration of the medication.
