A nurse is caring for a client with a history of overdosage of aspirin. The nurse suspects which of the following can be an early sign of aspirin toxicity?

Correct Answer: D

Rationale: Tinnitus, or ringing in the ears, can be an early sign of aspirin toxicity. Aspirin poisoning can lead to salicylate toxicity, which can manifest with various symptoms including tinnitus, along with hyperventilation, nausea, vomiting, and metabolic acidosis. Monitoring for tinnitus is crucial as an early indicator of potential aspirin overdose in clients. Unsteady gait, drowsiness, and confusion are also symptoms of aspirin toxicity but typically develop after tinnitus in the progression of toxicity.

Correct Answer: A

Rationale: Warfarin is an anticoagulant medication commonly used to prevent blood clots. One of the most severe adverse effects of warfarin is the risk of bleeding. This can occur in various parts of the body, such as the gastrointestinal tract, brain, or other organs. Bleeding complications can range from minor bruising to life-threatening hemorrhages, especially if warfarin levels are not properly monitored. Patients taking warfarin should be closely monitored for signs of bleeding, and their medication dosages should be adjusted as needed to maintain a balance between preventing clotting and avoiding excessive bleeding.

Correct Answer: C

Rationale: Insomnia is not a common side effect of Alprazolam. Alprazolam is a benzodiazepine medication commonly used to treat anxiety and panic disorders. Common side effects of Alprazolam include dizziness, drowsiness, and lethargy. However, it is not typically associated with causing insomnia as a side effect. If a person experiences unusual symptoms while taking Alprazolam, they should consult their healthcare provider for guidance.

Correct Answer: A

Rationale: Increasing the temperature does not result in local analgesia. In fact, higher temperatures can often lead to increased pain sensitivity. Local analgesia is achieved through methods such as chemically or physically damaging nerve trunks, stimulating large fiber nerve activity, or rendering tissue anemic. These procedures work by interrupting the transmission of pain signals to the brain or by reducing the sensitivity of local nerve endings to pain stimuli.

Correct Answer: D

Rationale: H1 receptor antagonists are primarily used for the treatment and prevention of allergic reactions. They work by blocking the H1 receptors, which are responsible for mediating allergic responses such as itching, swelling, and inflammation. This action helps to alleviate symptoms of allergies like sneezing, itching, and runny nose.
