A nurse is preparing to administer blood to a client. The unit of blood on hand is type B, and the client has type AB blood. Which of the following actions should the nurse take?

Choice A Reason: Albumin 25% is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Albumin 25% is a colloid solution that increases the oncotic pressure and draws fluid from the interstitial space into the intravascular space, which can worsen the intracranial pressure by increasing the cerebral blood flow and edema.

Choice B Reason: Dextran 70 is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Dextran 70 is a plasma expander that increases the blood volume and viscosity, which can also worsen the intracranial pressure by increasing the cerebral blood flow and edema.

Choice C Reason: Mannitol 25% is a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Mannitol 25% is an osmotic diuretic that reduces the intracranial pressure by creating an osmotic gradient and drawing fluid from the brain tissue into the blood vessels, which can then be excreted by the kidneys. The nurse should monitor the urine output, serum osmolality, and electrolytes when administering mannitol 25%.

Choice D Reason: Hydroxyethyl starch is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Hydroxyethyl starch is another plasma expander that has similar effects as dextran 70, and can also increase the risk of coagulopathy and renal failure.

Choice A Reason: This is incorrect because the client is not in deep coma, as the Glasgow Coma Scale (GCS) score ranges from 3 to 15, with 3 being the lowest possible score and indicating deep coma or death.

Choice B Reason: This is correct because the client needs total nursing care, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only open his eyes to pain, make incomprehensible sounds, and have abnormal flexion to pain.

Choice C Reason: This is incorrect because the client is not alert and oriented, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may not be able to follow commands, answer questions, or recognize people or places.

Choice D Reason: This is incorrect because the client is not responding to verbal stimuli, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only respond to painful stimuli, such as pinching or squeezing.
