Which of the following is the most appropriate treatment for this patient. given the likely diagnosis of acute sinusitis?
Nasal saline irrigation alone
Oral decongestants alone
Oral antibiotics
Intranasal corticosteroids alone
The Correct Answer is C
In cases of acute bacterial sinusitis that last longer than 10 days, worsen after initial improvement, or present with severe symptoms (such as fever and significant facial pain), oral antibiotics are generally indicated. First-line options typically include amoxicillin-clavulanate.
Other options listed, such as nasal saline irrigation, oral decongestants, or intranasal corticosteroids, may help alleviate symptoms but would not address the bacterial infection, making antibiotics the most appropriate primary treatment in this case.

Correct Answer is C
Explanation
A. The intracellular space contains most of the body's water: While it is true that the intracellular space holds the majority of the body's water, this statement does not specifically relate to the concept of fluid volume deficit or how the body responds to it.
B. A fluid volume deficit inhibits baroreceptors: In fact, fluid volume deficit activates baroreceptors due to reduced blood pressure, leading to compensatory mechanisms like increased heart rate and vasoconstriction to maintain blood pressure.
C. When the body loses water, the intravascular space experiences the water loss: This statement accurately describes the process during fluid volume deficit. The intravascular space loses water, leading to decreased blood volume, which can result in symptoms like hypotension and reduced tissue perfusion.
D. A negative fluid balance occurs when the body takes in more water than the body needs: This statement is incorrect; a negative fluid balance occurs when the body loses more water than it takes in, leading to dehydration or fluid volume deficit.
Correct Answer is D
Explanation
A. Impaired carbon dioxide elimination due to shunting: In ARDS, shunting can impair oxygenation but not directly carbon dioxide elimination. Shunting refers to blood flow through areas of the lung that are not ventilated properly, primarily affecting oxygenation.
B. Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch: ARDS is typically associated with increased, not decreased, pulmonary arterial pressure due to the inflammatory process and reduced lung compliance. V/Q mismatch in ARDS usually results in elevated pulmonary arterial pressure.
C. Hypoxemia due to dead space: ARDS hypoxemia results from impaired gas exchange in damaged alveoli rather than dead space, which is more related to ventilation without perfusion.
D. Decreased pulmonary compliance due to stiffness: ARDS is characterized by decreased pulmonary compliance, which is due to the stiffening of lung tissue from inflammation and edema. This stiffness makes lung expansion more difficult and is a key feature of ARDS.
