Choice A rationale:

The medication should be dropped into the conjunctival sac, which is the space between the lower eyelid and the eyeball. This is the correct method for administering ophthalmic drops.

Choice B rationale:

The eyedropper should not touch any part of the eye, including the sclera, to avoid contamination and potential infection.

Choice C rationale:

It is not necessary to don sterile gloves when administering ophthalmic drops. Clean gloves or hand hygiene is sufficient.

Choice D rationale:

Rubbing the eye after instilling medication can cause irritation and may disperse the medication, reducing its effectiveness.

Correct Answer is C

Explanation

Choice A rationale:

The thickest part of the heart is not the upper chambers but the lower chambers, specifically the left ventricle. This is because it needs to pump blood to the entire body.

Choice B rationale:

Blood leaves the heart through the lower chambers, or ventricles, not the upper chambers.

Choice C rationale:

Blood enters the heart through the upper chambers, or atria. This is where deoxygenated blood from the body and oxygenated blood from the lungs first enter the heart.

Choice D rationale:

The term “ventricles” refers to the lower chambers of the heart, not the upper chambers.

A. Respiratory acidosis. B. Metabolic acidosis. C. Respiratory alkalosis. D. Metabolic alkalosis.

Correct Answer is D

Explanation

Choice A rationale:

Respiratory acidosis is characterized by a high PaCO2 and a low pH. The client’s ABG results do not match this pattern.

Choice B rationale:

Metabolic acidosis is characterized by a low HCO3 and a low pH. The client’s ABG results do not match this pattern.

Choice C rationale:

Respiratory alkalosis is characterized by a low PaCO2 and a high pH. The client’s ABG results do not match this pattern.

Choice D rationale:

Metabolic alkalosis is characterized by a high HCO3 and a high pH. The client’s ABG results match this pattern. Normal values for pH, PaCO2, and HCO3 are 7.35-7.45, 35-45 mm Hg, and 22-26 mEq/L respectively.
