What is the correct term for blood flow through the lung?

A) This is normal.
Guaifenesin is an expectorant medication commonly used to help loosen and thin mucus in the airways, making it easier to cough up. Coughing up phlegm after taking guaifenesin is an expected response and indicates that the medication is working as intended. Guaifenesin helps to clear the airways of excess mucus, which can be particularly beneficial for individuals with respiratory conditions such as bronchitis or chest congestion.

B) This requires further investigation.
Coughing up phlegm after taking guaifenesin is a common and expected response and does not typically indicate a need for further investigation unless there are other concerning symptoms present. It is important for the nurse to provide reassurance and education about the expected effects of the medication.

C) This is indicative of an allergic reaction.
Coughing up phlegm after taking guaifenesin is not indicative of an allergic reaction. Allergic reactions to guaifenesin are rare but may include symptoms such as rash, itching, swelling, dizziness, or difficulty breathing. If the client were experiencing these symptoms, it would be important to assess further for a possible allergic reaction and intervene accordingly.

D) This means there is probably more pathology present.
Coughing up phlegm after taking guaifenesin does not necessarily indicate the presence of more pathology. It simply indicates that the medication is helping to loosen and mobilize mucus in the airways, which is a normal response to expectorant therapy. If the client has concerns about their symptoms, further assessment by a healthcare provider may be warranted, but coughing up phlegm alone is not necessarily indicative of worsening pathology.

A) "The amount of blood pumped by the heart through the circulatory system in 1 minute."
This statement describes cardiac output, which is the volume of blood pumped by the heart per minute, and is not directly related to digestion.

B) "Smooth muscle movement of the GI tract by way of contractions."
This statement describes peristalsis, which is the rhythmic contraction of smooth muscles in the gastrointestinal tract that propels food and waste materials through the digestive system. While peristalsis is an important aspect of digestion, it does not encompass the entire process.

C) "Neutralization by use of bicarbonate from pancreatic and biliary secretions."
This statement refers to the neutralization of acidic chyme from the stomach by bicarbonate ions released from pancreatic and biliary secretions in the duodenum. While this process is a part of digestion, it specifically addresses the regulation of pH rather than the breakdown of food molecules into absorbable forms.

D) "It is the process when food is broken down into molecules that can be absorbed."
This statement accurately describes digestion, which is the process by which complex food molecules are broken down into simpler forms (such as carbohydrates into sugars, proteins into amino acids, and fats into fatty acids and glycerol) that can be absorbed and utilized by the body. Digestion occurs in various stages along the gastrointestinal (GI) tract and involves the action of enzymes, acids, and mechanical processes to facilitate the breakdown of food into absorbable nutrients.
