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 A
Explanation
In case of suspected ingestion of a poisonous substance, the priority response of the poison control nurse should be to assess the child's vital signs, especially breathing and heart rate, to determine if the child is experiencing any immediate life-threatening symptoms. This information will help the nurse determine the appropriate course of action, such as whether to instruct the caregiver to perform CPR or to immediately call for emergency medical assistance.
Asking about the substance ingested and the time of ingestion are also important pieces of information to gather, but they should not take priority over assessing the child's vital signs. Inducing vomiting is generally not recommended unless instructed to do so by a medical professional, as it can cause further harm if the substance ingested is corrosive or caustic.
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.
