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

Answer and Explanation

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 A

Explanation

A. "Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.": This statement accurately describes diffusion. Molecules move down their concentration gradient from areas of higher concentration to areas of lower concentration until equilibrium is reached.

B. "Diffusion is the movement of particles between areas of equal concentrations.": Diffusion does not occur between areas of equal concentration as there is no concentration gradient to drive the movement.

C. "Diffusion is the movement of water from an area of higher concentration of water to an area of lower concentration of water.": This describes osmosis, not diffusion. Osmosis specifically refers to the movement of water across a semipermeable membrane.

D. "Diffusion is the movement of particles from an area of lower concentration of particles to an area of higher concentration of particles.": This is incorrect as diffusion occurs from higher to lower concentration, not the reverse.

A. Hyperventilation B. Bradypnea C. Syncope D. U waves on electrocardiogram

Correct Answer is D

Explanation

A. Hyperventilation: Hyperventilation is more commonly associated with respiratory alkalosis or anxiety rather than hypokalemia. Hypokalemia does not typically cause hyperventilation.

B. Bradypnea: Bradypnea (slow breathing) is not a common finding in hypokalemia. Hypokalemia can affect muscle function, including respiratory muscles, but bradypnea is not a characteristic sign.

C. Syncope: While syncope (fainting) can occur due to various conditions, it is not a specific or common finding directly associated with hypokalemia. Hypokalemia mainly affects the heart and muscles.

D. U waves on electrocardiogram: U waves are a classic electrocardiogram (ECG) finding associated with hypokalemia. These waves appear after the T wave and are indicative of the electrolyte imbalance affecting cardiac repolarization.
