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
When someone has asthma, their lungs may produce a wheezing sound when they breathe in and out. Narrowed airways and restricted air movement through the lungs may be responsible for the wheezing sound.
Correct Answer is A
Explanation
Pulse oximetry is a non-invasive method of monitoring the oxygen saturation level in the blood. A normal range for oxygen saturation is between 95% and 100%. An oxygen saturation level of 89% indicates hypoxemia, which is a serious condition that can lead to tissue damage, organ failure, and even death if left untreated.
Therefore, the priority nursing action is to perform a respiratory assessment to determine the cause of the hypoxemia. This should include assessing the client's airway patency, breathing patern, lung sounds, and oxygen therapy if the client is already receiving it. The nurse should also observe for any signs of respiratory distress such as cyanosis, accessory muscle use, or difficulty breathing.
While it is important to document hypoxemia and report it to the healthcare provider, the priority at this time is to assess and intervene promptly to prevent further deterioration of the client's condition. Checking the placement of the pulse oximeter may be necessary if the reading is unreliable, but it is not the priority in this scenario.
