The nurse is listening to the heart sounds of a client. The nurse recognizes that the S2:
Indicates the beginning of diastole
Coincides with the carotid artery pulse
is louder than an S1
Is caused by the closure of the semilunar valves
The Correct Answer is D
A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.
B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.
C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.
D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.

Correct Answer is A
Explanation
A. Maxillary sinusitis:
Explanation: The client's symptoms of facial pain, fever, malaise, swollen turbinates, purulent nasal discharge, and dull, throbbing pain in the cheeks and teeth on the right side, especially when palpated, are indicative of maxillary sinusitis. Maxillary sinusitis refers to the inflammation of the maxillary sinuses, which are located in the cheek area. The symptoms described align with a bacterial infection in this sinus.
B. Nasal polyps:
Explanation: Nasal polyps are soft, noncancerous growths on the lining of the nasal passages or sinuses. While they can cause nasal congestion and a runny nose, they do not typically present with the specific symptoms mentioned in the scenario, such as facial pain, fever, and purulent discharge.
C. Frontal sinusitis:
Explanation: Frontal sinusitis involves inflammation of the frontal sinuses located in the forehead area. Symptoms may include forehead pain, headache, and nasal discharge. However, the described symptoms in the scenario (dull, throbbing pain in the cheeks and teeth on the right side) are more characteristic of maxillary sinusitis.
D. Posterior epistaxis:
Explanation: Posterior epistaxis refers to a nosebleed that originates from the back of the nose, often due to bleeding from the sphenopalatine artery. While nosebleeds can cause blood drainage into the throat and result in a metallic taste, the other symptoms described in the scenario, such as facial pain, fever, and purulent discharge, are not indicative of posterior epistaxis.
Correct Answer is C
Explanation
In this sequence:
Vena cava brings deoxygenated blood from the body into the right atrium.
Blood flows from the right atrium to the right ventricle through the tricuspid valve.
The right ventricle pumps blood into the pulmonary artery to the lungs.
In the lungs, blood is oxygenated and returns to the heart via the pulmonary veins into the left atrium.
From the left atrium, blood moves to the left ventricle through the bicuspid (mitral) valve.
The left ventricle then pumps oxygenated blood into the body through the aorta.
This sequence represents the systemic and pulmonary circulation of the heart.
