A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.1"]
To calculate the amount of haloperidol (in mL) that the nurse should administer, use the following formula:
Volume (mL)= Dose (mg)/Concentration (mg/mL)
In this case:
Volume (mL)=5 mg/50 mg/mL
Volume (mL)= 0.1 mL
Therefore, the nurse should administer 0.1 mL of haloperidol.

Correct Answer is C
Explanation
A. Elevated heart rate is not a typical sign of opioid toxicity. Opioids usually have a depressant effect on the cardiovascular system, leading to bradycardia.
B. Hypertension is not a typical effect of opioid toxicity. Opioids often cause hypotension due to vasodilation.
C. Pupillary constriction (miosis).
Acute fentanyl toxicity is associated with opioid overdose, and opioids typically cause miosis (constriction of the pupils). Other common symptoms of opioid toxicity include respiratory depression, sedation, and potentially unconsciousness.
D. Tachypnea is not a typical sign of opioid toxicity. Opioids tend to depress the respiratory system, leading to respiratory depression and potentially hypoventilation.
Correct Answer is A
Explanation
A. The criteria for involuntary commitment typically involve assessing whether the individual presents a danger to themselves or others. If the client continues to pose a significant risk of harm to themselves or others, the involuntary hold may be extended.
B. Whether the client is unwilling to accept that treatment is needed is relevant to the overall treatment plan, but it may not be the primary criterion for involuntary commitment. The focus is often on the immediate risk of harm.
C. Whether the client is financially incapable of paying for prescribed medications is not typically a consideration in the decision to extend an involuntary hold. The decision is primarily based on the risk of harm to the client or others.
D. Whether the client is unable to make arrangements to stay with someone is not a primary criterion for involuntary commitment. The decision is based on the assessment of the client's immediate danger to themselves or others.
