The nursing diagnosis that would have the highest priority in the care of the client who has become comatose following cerebral hemorrhage is which of the following?

Choice A reason: Cocaine reduces appetite; high energy is a symptom. This errors per nursing pharmacology. It’s universally distinct, opposite effect.

Choice B reason: Cocaine raises heart rate, not lowers it. Energy fits, per standards. This misaligns with drug effects. It’s universally distinct, incorrect.

Choice C reason: Drowsiness opposes cocaine’s stimulant nature; energy is correct. This errors per nursing knowledge. It’s universally distinct, sedative-based.

Choice D reason: High energy is a key sign of cocaine intoxication, per pharmacology. This aligns with nursing standards. It’s universally recognized, distinctly accurate.

Choice A reason: Vectors, like mosquitoes, biologically transmit pathogens, as in malaria. Blood here isn’t a living carrier but a medium containing potential agents, like hepatitis viruses, making it distinct from the active, intermediary role vectors play in disease spread epidemiologically and consistently.

Choice B reason: The agent in the epidemiological triangle is the pathogen causing disease, like viruses in blood. Here, blood contacting skin carries potential infectious agents, such as HIV, directly linking it to the causative factor in this exposure scenario biologically and accurately.

Choice C reason: Environment includes external factors, like contaminated surfaces, facilitating transmission. Blood is the direct pathogen source, not a setting or condition, distinguishing it as the agent itself rather than the broader context of exposure in this epidemiological model clearly.

Choice D reason: The host is the affected organism, here the nurse or patient, not the blood. Blood carries the agent, like bacteria, targeting the host’s susceptibility, separating it from the recipient role hosts play in disease dynamics distinctly and fundamentally here.
