Correct Answer: D

Rationale: In severe Aspirin toxicity, respiratory depression is an anticipated finding due to the development of respiratory acidosis. Aspirin toxicity can lead to metabolic acidosis, causing the individual to hyperventilate initially to compensate. However, as the condition progresses, respiratory depression can occur, resulting in impaired gas exchange and respiratory acidosis.

Correct Answer: C

Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at bedtime as it helps decrease the production of stomach acid during the night, providing optimal relief for conditions like heartburn or acid indigestion.

Rationale: Protamine is the antidote for heparin, as it reverses its anticoagulant effects. In cases of heparin overdose or if there is excessive bleeding, administering protamine can quickly neutralize the effects of heparin, helping to prevent further bleeding complications.

Correct Answer: B

Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

Correct Answer: A

Rationale: The nurse should instruct the client to report tinnitus because it can be an indication of ototoxicity, a potential adverse effect of cisplatin. Ototoxicity can manifest as tinnitus, hearing loss, or balance disturbances, so it is crucial for the client to promptly report any changes in hearing such as tinnitus to prevent further damage.
