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
Crackles, also known as rales, are discontinuous sounds that are typically heard during inspiration in patients with heart failure. These sounds are produced by the sudden opening of small airways and alveoli that are filled with fluid or collapsed due to pulmonary congestion. The sound can be described as similar to the sound of rubbing hair between fingers or the sound of Velcro being pulled apart.
Rhonchi are continuous, low-pitched sounds that are typically heard during expiration and are caused by the movement of air through narrowed airways, such as in patients with chronic obstructive pulmonary disease (COPD). Stridor is a high-pitched, continuous sound that is typically heard during inspiration and indicates upper airway obstruction, which can be life-threatening. Neither rhonchi nor stridor are typically heard in patients with heart failure.
Therefore, based on the patient's history and symptoms, the most likely type of breathing sound to be heard on auscultation is crackles/rales.
Correct Answer is C
Explanation
An Incentive Spirometer is a device that helps patients take deep breaths and improve their lung function. It encourages patients to take deep breaths and to hold them for a few seconds. The device also helps to monitor and measure lung volume. By using an incentive spirometer, MA can expand her lung volume as much as possible and allow for proper oxygen blood exchange within the alveoli. This is an important technique to help prevent pneumonia and other respiratory complications.
The other options mentioned, 4L of oxygen via Nasal Cannula, Fluter Valve, and Abdominal Binder, are not appropriate devices to help MA achieve proper breathing techniques and expand lung volume. 4L of oxygen via Nasal Cannula is used to provide supplemental oxygen to patients who have difficulty breathing. Fluter Valve is a handheld device used for airway clearance in patients with chronic obstructive pulmonary disease (COPD) or cystic fibrosis. An abdominal binder is a wrap that is placed around the abdomen to support the abdominal muscles and help reduce pain after surgery or injury. These devices do not help improve lung function and are not appropriate for MA's condition.
