A nurse is preparing to minister amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer? (Round to the nearest whole number.)
The Correct Answer is ["7"]
To calculate the volume (mL) of amoxicillin needed, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Given that the dose is 350 mg and the concentration is 250 mg/5 mL:
Volume (mL) = 350 mg / 250 mg/5 mL
First, calculate the concentration of amoxicillin in mg/mL:
250 mg / 5 mL = 50 mg/mL
Now, use the calculated concentration to find the volume:
Volume (mL) = 350 mg / 50 mg/mL = 7 mL
So, the nurse should administer 7 mL of amoxicillin.

Correct Answer is C
Explanation
A. Bleeding:
Explanation: Bleeding is not a common adverse effect of haloperidol, which is an antipsychotic medication used to treat conditions like schizophrenia. Haloperidol primarily works on the central nervous system and is not known to directly cause bleeding issues.
B. Cataracts:
Explanation: Cataracts are not a common adverse effect of haloperidol either. While long-term use of some antipsychotic medications can lead to metabolic and endocrine disturbances, which might indirectly impact eye health, cataracts are not a direct and immediate concern with haloperidol use.
C. Dysrhythmias:
Explanation: Correct Answer. Haloperidol has the potential to cause cardiac-related adverse effects, including dysrhythmias (irregular heart rhythms). This is a particular concern in individuals who are predisposed to heart conditions or have other risk factors. The medication can prolong the QT interval, which is a measure of the time it takes for the heart's electrical system to recharge between beats. Prolonged QT interval can lead to serious and potentially life-threatening arrhythmias.
D. Pancreatitis:
Explanation: Pancreatitis is not a common adverse effect of haloperidol. Pancreatitis typically involves inflammation of the pancreas and can be caused by various factors such as gallstones, alcohol consumption, and certain medications. Haloperidol is not known to directly cause inflammation of the pancreas.
Correct Answer is D
Explanation
A. "I can see that you trust me, but you should share those feelings with your psychiatrist, not me."
While encouraging the client to discuss their feelings with a mental health professional is important, this response does not address the immediate safety concern presented by the client's intent to harm others.
B. "I will not violate our nurse-client relationship. The information we discuss will remain confidential between us."
This response is inappropriate because it implies that the nurse will keep the information confidential, even though the client's statement raises concerns about the safety of others.
C. "Because you are a minor, I have to share any information that I feel is important with your parents."
While parents may have the right to be informed about their minor child's well-being, this situation goes beyond parental involvement. The nature of the threat requires immediate intervention from appropriate professionals and authorities.
"D. I cannot promise that. I must share this information with other members of the team who are responsible for planning your care."
Explanation: The client's statement about having a desire to harm others, especially classmates and a school teacher, raises significant concerns about the safety and well-being of not only the client but also the potential victims. In cases where the client poses a risk of harm to themselves or others, the nurse has a duty to breach confidentiality to ensure the safety of all involved parties. This response conveys the nurse's ethical obligation to involve other members of the treatment team and appropriate authorities to address the potential threat.
