A nurse is preparing to administer ziprasidone 10 mg IM every 6 hr. Available is ziprasidone 20 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the amount of ziprasidone 10 mg IM from the available concentration of 20 mg/mL, you can use the formula:
Amount (mL) = Desired Dose (mg) / Concentration (mg/mL)
Amount (mL) = 10 mg / 20 mg/mL
Amount (Ml) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of ziprasidone per dose.

Correct Answer is ["B","D","E"]
Explanation
A. Nystagmus: Nystagmus is not a typical manifestation of alcohol withdrawal. It is more commonly associated with intoxication or neurological conditions. Therefore, it is not included in the effects of alcohol withdrawal.
B. Illusions: Illusions (misinterpretations of external stimuli) are common during alcohol withdrawal, especially in severe cases such as withdrawal delirium (delirium tremens). Clients may misinterpret shadows or objects as threatening.
C. Polyphagia: Polyphagia (excessive eating) is not a recognized manifestation of alcohol withdrawal. Clients with withdrawal may experience nausea or a lack of appetite rather than an increased appetite.
D. Tremors: Tremors, often called "the shakes," are one of the most common early signs of alcohol withdrawal. They usually begin within hours after alcohol cessation.
E. Seizures: Seizures, specifically generalized tonic-clonic seizures, are a serious complication of alcohol withdrawal. They can occur within 6–48 hours after the last drink and are part of alcohol withdrawal syndrome.
Correct Answer is D
Explanation
While preventing injury is important, it is not the highest priority when the client's respiratory and neurological functions are compromised. Managing the client's breathing takes precedence.
B. Applying a cooling blanket.
While hyperthermia (high fever) is a symptom of serotonin syndrome, the immediate concern is ensuring the client's breathing and neurological stability. Cooling measures can be beneficial, but they come after addressing the more critical issues.
C. Administering an anticonvulsant.
While anticonvulsants might be used to control seizures, preparing for artificial ventilation takes priority, as the client's airway and oxygenation must be secured before addressing other symptoms.
D. Preparing for artificial ventilation.
Explanation: Serotonin syndrome is a potentially life-threatening condition caused by an excess of serotonin in the body, often resulting from interactions between medications that affect serotonin levels. Severe manifestations of serotonin syndrome can include high fever, muscle rigidity, agitation, seizures, and even coma. In cases of severe serotonin syndrome, the client's neurological and respiratory functions can be compromised, making it crucial to ensure adequate ventilation and oxygenation.
