Following a gunshot wound, an adult client has a hemoglobin level of 4 g/dL (40 g/L). The nurse prepares to administer a unit of blood for an emergency transfusion. The client has AB negative blood type and the blood bank sends a unit of Type A Rh negative, reporting that there is no Type AB negative blood currently available. Which intervention should the nurse implement?

Choice A reason: Checking the client's current fingerstick blood glucose is important to determine if the confusion and weakness are due to hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).

Choice B reason: Obtaining blood pressure and heart rate is useful for a general assessment but is secondary to assessing blood glucose levels in this scenario.

Choice C reason: Administering a PRN dose of regular insulin is not appropriate without first determining the client's blood glucose level. If the client is hypoglycemic, insulin could worsen the condition.

Choice D reason: Giving the client 4 ounces (120 mL) of orange juice is a quick way to raise blood sugar levels if the client is hypoglycemic.

Choice E reason: Providing diet carbonated soda is not effective for treating hypoglycemia because it does not contain sugar to raise blood glucose levels.

Choice A reason: A history of suicide attempts is crucial information when planning the care of a client using heroin because there is a high risk of further suicide attempts, especially in individuals with substance use disorders. The nurse must prioritize mental health safety and implement measures to monitor and support the client's psychological well-being to prevent any potential self-harm.

Choice B reason: While family history of schizophrenia is important, it is not immediately crucial to the plan of care for a client currently using heroin. This information is more relevant for long-term monitoring and psychiatric evaluation rather than immediate care planning.

Choice C reason: Undiagnosed social anxiety disorder (SAD) may contribute to substance use; however, it is not the most urgent concern in this scenario. The focus should be on immediate safety and stabilization, particularly addressing the high risk of suicide.

Choice D reason: Feelings of disorientation are significant but could be a result of heroin use. While important to assess, they are secondary to the immediate concern of preventing self-harm in a client with a history of suicide attempts.
