Aspirin can irritate the gastrointestinal tract and disrupt the protective lining, leading to potential bleeding, especially after high consumption. This risk increases with prolonged use, making it a significant concern for patients.
B: Breathing difficulties
Breathing difficulties are not a common side effect associated with aspirin overdose. Aspirin primarily affects the gastrointestinal system rather than the respiratory system, making this option less relevant.
C: Visual disturbances
Visual disturbances do not typically correlate with aspirin intake. While certain medications may induce such effects, aspirin's primary risks lie elsewhere, particularly in the gastrointestinal area.
D: Loss of balance
Loss of balance is not directly linked to aspirin usage. This symptom usually relates to neurological issues or inner ear problems, which do not arise from aspirin consumption.

Question 26
Regular
A patient has been using sleeping pills every night for the past several months. Now admitted to the hospital, he is prescribed his usual dose of sleeping pill. After administration, the patient continues to be restless and is wide awake. The nurse notifies the health care provider, who prescribes an increased dose. After receiving the new dose, the patient falls asleep. The nurse interprets this as which of the following?
Correct!
Incorrect
The correct answer is: C
Rationale
The patient exhibits drug tolerance.
This situation illustrates that the patient has developed tolerance to sleeping pills, requiring a higher dose to achieve the desired sedative effect after prolonged use. As a result, the initial dosage was insufficient to induce sleep, necessitating an increase for effectiveness.
A: Drug idiosyncrasy Unusual reactions to drugs occur unpredictably and do not match the typical responses, which does not apply here as the patient's behavior aligns with known tolerance patterns.
B: Cumulative drug effect This refers to the accumulation of a drug in the body leading to increased effects over time, which is not relevant since tolerance indicates diminished response rather than cumulative effects.
D: Toxic reactions Toxic reactions involve harmful effects at therapeutic doses, but in this case, the patient simply required a higher dosage for the same therapeutic effect, not exhibiting toxicity.
