A patient’s hemoglobin is severely low and she is complaining of being overly tired and fatigued. You are educating her on the role hemoglobin has with oxygenation and perfusion. You will know she understands the role of hemoglobin when she tells you hemoglobin transports:
Carbon Monoxide
Oxyhemoglobin
Carbon Dioxide
Carboxyhemoglobin
The Correct Answer is B
Hemoglobin is a protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the body's tissues and organs. When oxygen is breathed in, it binds to the hemoglobin in red blood cells, forming oxyhemoglobin. This oxyhemoglobin is then transported throughout the body via the circulatory system, delivering oxygen to the cells that need it

Correct Answer is B
Explanation
Hyponatremia is a condition where the sodium levels in the blood are abnormally low. It can cause confusion, seizures, and even coma in severe cases. The IV fluids hanging are 0.33% NaCI, which means they have a low sodium concentration, and may be contributing to the patient's hyponatremia.
Given that the patient is becoming increasingly confused, it is important to assess his mental status and monitor him closely to prevent harm. However, restraining the patient should not be the first course of action. Instead, the nurse should focus on identifying the underlying cause of the hyponatremia and taking appropriate steps to address it.
Therefore, the next step would be to get an order for additional lab work to assess the patient's electrolyte levels and identify the cause of the hyponatremia. This will help to guide further treatment and management decisions for the patient.

Correct Answer is A
Explanation
A. Respiratory acidosis.
COPD is a chronic lung disease that can lead to an accumulation of carbon dioxide (CO2) in the body. This can cause respiratory acidosis, a condition in which the blood pH is lower than normal due to an excess of CO2.
In respiratory acidosis, the partial pressure of carbon dioxide (PaCO2) in the blood is increased and the pH is decreased. The kidneys atempt to compensate for the acidosis by excreting more acid in the urine and retaining more bicarbonate, but this compensation is usually not enough to fully correct the problem.
Metabolic alkalosis (option B) is a condition in which the blood pH is higher than normal due to an excess of bicarbonate in the blood. This is usually caused by loss of acid from the body, such as through vomiting or use of diuretics.
Respiratory alkalosis (option C) is a condition in which the blood pH is higher than normal due to a decrease in PaCO2. This can be caused by hyperventilation, which leads to excessive elimination of CO2 from the lungs.
Metabolic acidosis (option D) is a condition in which the blood pH is lower than normal due to an excess of acid in the blood. This can be caused by a variety of factors, including kidney failure or lactic acidosis.
