A patient presents to the Emergency Room with swollen legs and shortness of breath. He tells you that he has a history of heart failure which causes the fluid to build up m his legs and lungs. When you listen to his lung sounds you are most likely to hear which type of breathing sounds?
Rales
Crackles
Rhonchi
Stridor
The Correct Answer is B
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
Dehydration can cause a decrease in blood volume, leading to a drop in blood pressure (hypotension) and an increase in heart rate (tachycardia) as the body tries to compensate. Tenting skin and dry mucous membranes are also signs of dehydration, but wet mucous membranes are not. Crackles in the lungs, edema, and confusion can occur with fluid overload, but not with dehydration.
Correct Answer is B
Explanation
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
