A nurse is caring for a patient who is receiving warfarin therapy to prevent deep vein thrombosis. Which of the following medications should the nurse have available in the event of an overdose?
Atropine
Protamine
Vitamin K
Epinephrine
The Correct Answer is C
Choice A reason: Atropine is used to treat bradycardia and is not an antidote for warfarin overdose.
Choice B reason: Protamine is used to reverse the effects of heparin, not warfarin.
Choice C reason: Vitamin K is the antidote for warfarin overdose as it helps in the synthesis of clotting factors that warfarin inhibits.
Choice D reason: Epinephrine is used for severe allergic reactions and cardiac arrest, not as an antidote for warfarin overdose.

Correct Answer is A
Explanation
Choice A reason: Poor nutritional status can impair wound healing and increase the risk of wound dehiscence.
Choice B reason: Medication administration is too vague to determine a risk for dehiscence without specifying the type of medication.
Choice C reason: Obesity can increase the risk of dehiscence due to the strain on the wound from excess tissue.
Choice D reason: Nonadherence could contribute to dehiscence if it refers to not following postoperative care instructions, but it is not specific enough in this context.
Choice E reason: An increased metabolic rate can lead to higher demands on the body's healing process, potentially affecting wound integrity.
Correct Answer is B
Explanation
Choice A reason: The patient's son may be present for support, but he does not have the authority to sign the consent form unless he is a designated health care proxy and the patient is not competent.
Choice B reason: Since the patient is alert and competent, she has the right and responsibility to provide consent for her own medical procedures.
Choice C reason: A health care proxy is authorized to make decisions on behalf of the patient only if the patient is unable to do so.
Choice D reason: The consent form should be signed by the patient alone if she is competent, regardless of who accompanies her to the facility.
