The health care provider orders a trough level of an antibiotic administered every twenty four hours.
When should the nurse plan for a trough level to be drawn?
Every morning at 08:00AM (0800).
Halfway between next scheduled dose.
Just prior to next scheduled dose.
Two hours after a scheduled dose.
The Correct Answer is C
Just prior to the next scheduled dose. A trough level is the lowest concentration of a drug in the blood, and it is measured just before the next dose is due to be administered.
This helps to ensure that the drug level does not fall below the therapeutic range or rise above the toxic range.
Choice A is wrong because every morning at 08:00 AM (0800) is not a consistent time interval for a drug that is administered every twenty-four hours.
The trough level should be measured at the same time before each dose.
Choice B is wrong because halfway between next scheduled dose is not a trough level, but a midpoint level.
This does not reflect the lowest concentration of the drug in the blood.
Choice D is wrong because two hours after a scheduled dose is not a trough level, but a peak level. This is the highest concentration of the drug in the blood, and it is measured after the drug has been absorbed and distributed. Peak levels are no longer routinely recommended for vancomycin.

Correct Answer is D
Explanation
You need to speak to the designated hospital contact. This is because the nurse has a duty to protect the client’s privacy and confidentiality, and cannot disclose any information about the client’s diagnosis or condition to the reporter without the client’s consent.
The nurse should refer the reporter to the hospital’s public relations department or spokesperson, who is authorized to handle such inquiries.
Choice A is wrong because it implies that the client’s healthcare provider can release the information without the client’s consent, which is not true.
Choice B is wrong because it confirms that the client is on the unit, which is a violation of the client’s privacy.
Choice C is wrong because it gives false information about the client’s status, which is unethical and unprofessional.
Correct Answer is C
Explanation
This is because responding inappropriately to questions can indicate that the client has difficulty hearing or understanding what is being asked. According to, hearing loss makes communication with the outside world difficult, and can result in new or exaggerated symptoms that are mistakenly attributed to cognitive decline.
Choice A is wrong because speaking in a low voice does not necessarily imply hearing loss. It could be due to other factors such as shyness, anxiety, or vocal cord problems.
Choice B is wrong because refusing to answer questions does not necessarily imply hearing loss.
It could be due to other factors such as lack of interest, defiance, or distrust.
Choice D is wrong because looking away from persons while speaking does not necessarily imply hearing loss.
It could be due to other factors such as cultural norms, eye contact avoidance, or distraction.
