A nurse is preparing to administer dabigatran to a client who has atrial fibrillation. The nurse should explain that the purpose of this medication is which of the following?

Choice A Reason: This is incorrect because this client has signs of brain death, such as severe head injuries, low respiratory rate, and unresponsiveness. The nurse should tag this client as black, which means deceased or expectant.

Choice B Reason: This is incorrect because this client has non-life-threatening injuries, such as a simple fracture and scratches. The nurse should tag this client as green, which means minor or delayed care.

Choice C Reason: This is incorrect because this client has minor injuries and is able to walk around. The nurse should tag this client as green, which means minor or delayed care.

Choice D Reason: This is correct because this client has a life-threatening condition called tension pneumothorax, which requires immediate care. This client has a life-threatening condition called tension pneumothorax, which is caused by air leaking into the pleural space and compressing the lung and the heart. This can lead to respiratory failure, cardiac arrest, and death if not treated immediately. The hissing sound indicates that air is escaping from the lung through the wound. The nurse should tag this client as red, which means immediate care is needed.

Choice A Reason: This is incorrect. Pulse and blood pressure findings are not reliable indicators of pain, as they can be influenced by many other factors, such as anxiety, medication, or underlying conditions. They are also not sensitive enough to detect changes in pain intensity or relief.

Choice B Reason: This is incorrect. Scheduled treatments and client illness are not relevant parameters for assessing pain, as they do not reflect the current pain experience of the client. They may provide some clues about the possible causes or sources of pain, but they do not measure the pain itself.

Choice C Reason: This is correct. A self-report pain rating scale is the most valid and reliable parameter for assessing pain, as it reflects the subjective perception of the client. The nurse should use a simple and appropriate scale, such as a numeric or visual analog scale, and ask the client to point to the number or picture that best represents their pain level.

Choice D Reason: This is incorrect. Behavioral indicators and affect are useful parameters for assessing pain, especially when the client has difficulty communicating verbally, but they are not the first choice. They are more subjective and variable than self-report, and they may be influenced by cultural or personal factors. They should be used in conjunction with self-report, not instead of it.
