A client asks the nurse what ventilation is. What is the most appropriate response by the nurse?
"Ventilation is the process of moving air into and out of the lungs."
"Ventilation is taking a breath in."
"Ventilation is the blood flow through the lung."
"Ventilation is the process by which gases are exchanged."
The Correct Answer is A
A) "Ventilation is the process of moving air into and out of the lungs."
Ventilation refers to the mechanical process of breathing, which involves the movement of air into and out of the lungs. During ventilation, air containing oxygen is drawn into the lungs through inhalation (inspiration), and carbon dioxide-rich air is expelled from the lungs through exhalation (expiration). This process facilitates the exchange of gases (oxygen and carbon dioxide) between the lungs and the external environment.
B) "Ventilation is taking a breath in."
This statement is too simplistic and does not fully encompass the process of ventilation, which includes both inhalation and exhalation. Ventilation involves not only taking a breath in but also the subsequent process of exhaling.
C) "Ventilation is the blood flow through the lung."
This statement describes perfusion, which is the process of blood flow through the lung's blood vessels, rather than ventilation, which involves air movement in and out of the lungs. Ventilation and perfusion are closely related but distinct processes.
D) "Ventilation is the process by which gases are exchanged."
While ventilation facilitates gas exchange, this statement does not fully capture the mechanical aspect of moving air into and out of the lungs, which is the primary function of ventilation. Gas exchange occurs in the alveoli of the lungs, where oxygen diffuses into the bloodstream, and carbon dioxide diffuses out of the bloodstream, but ventilation refers specifically to the movement of air.

Correct Answer is A
Explanation
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.
Correct Answer is ["10"]
Explanation
To administer the correct dose of valproic acid, which is 500 mg, when the available oral solution concentration is 250 mg per 5 mL, the nurse needs to calculate the volume of the solution required.
The calculation is as follows: (500 mg) / (250 mg/5 mL) = 2 x 5 mL = 10 mL.
Therefore, the nurse should administer 10 mL of the valproic acid oral solution to deliver a dose of 500 mg.
