Police bring a patient to the emergency department after an automobile accident. The patient is ataxic with slurred speech and mild confusion. The blood alcohol level is 400 mg/dl (0.4 mg %). Considering the relationship between behavior and blood alcohol level, which conclusion can the nurse draw? The patient:
- A. rarely drinks alcohol.
- B. has a high tolerance to alcohol.
- C. has been treated with disulfiram (Antabuse).
- D. has recently ingested both alcohol and sedative drugs.
Correct Answer: B
Rationale: The correct answer is B: the patient has a high tolerance to alcohol. At a blood alcohol level of 400 mg/dl, most individuals would exhibit severe symptoms such as unconsciousness or coma. However, this patient only shows mild symptoms of ataxia, slurred speech, and confusion, indicating a high tolerance to alcohol. This high tolerance suggests that the patient regularly consumes large amounts of alcohol, leading to an adaptation in the body's response to alcohol.
Choice A is incorrect because a blood alcohol level of 400 mg/dl is indicative of significant alcohol consumption, contradicting the statement that the patient rarely drinks alcohol. Choice C is incorrect as disulfiram is used to treat alcohol dependence, not tolerance. Choice D is incorrect since sedative drugs would exacerbate the effects of alcohol, causing more severe symptoms than what is observed in this case.

- B. Obtain only cats that are less than 1 year old.'
- C. Remove all pets from your home. Avoid all contact with cats.'
- D. Be sure all the cats have up-to-date immunizations, and avoid their feces.'
Correct Answer: D
Rationale: The correct answer is D because HIV-infected individuals are at higher risk for infections, including from Toxoplasma gondii found in cat feces. By ensuring cats have up-to-date immunizations and avoiding their feces, the patient can reduce the risk of infection.
A: Keeping cats outdoors most of the time does not address the risk from cat feces inside the house.
B: The age of the cat does not necessarily correlate with the risk of infection, so this advice is not relevant.
C: Removing all pets and avoiding all contact with cats is an extreme measure and not necessary if proper precautions are taken.
