A client is to receive 2 mg of haloperidol IM. The vial contains 5 mg per mL. What volume should the nurse administer?
The Correct Answer is ["0.4"]
Step 1: Desired dose = 2 mg
Step 2: Available concentration = 5 mg/mL
Step 3: Use the formula:
Volume to administer = Desired dose ÷ Concentration available
Step 4: Plug in the values:
Volume to administer = 2 mg ÷ 5 mg/mL = 0.4 mL

Correct Answer is ["B","D","E"]
Explanation
A. Fever and cardiac dysrhythmias are not specific complications of tissue plasminogen activator (t-PA) therapy. While they can occur after a stroke or as a general response to illness, they are not the primary indicators of complications related to thrombolytic therapy.
B. An elevated blood pressure combined with a headache could indicate a hemorrhagic transformation, which is a serious complication after t-PA administration. Thrombolytic therapy increases the risk of bleeding, and these symptoms may signal intracranial hemorrhage.
C. A positive Babinski's sign (extensor plantar response) is often seen in stroke patients as a neurological finding, but it is not specifically an indication of a complication from t-PA therapy. It is more reflective of the brain injury or stroke itself rather than the medication.
D. Nausea and vomiting can be signs of increased intracranial pressure (ICP), which could result from hemorrhage following t-PA therapy. This is a critical sign that requires immediate evaluation to rule out complications such as bleeding.
E. A decreased level of consciousness is a significant red flag and may indicate cerebral hemorrhage or another serious complication related to the administration of t-PA. Monitoring for changes in neurological status is crucial following thrombolytic therapy.
Correct Answer is ["480"]
Explanation
Convert time to hours:
25 minutes ÷ 60 = 0.4167 hours
Step 2:
Use the formula:
Rate (mL/hr) = Volume (mL) ÷ Time (hr)
Rate = 200 mL ÷ 0.4167 hr ≈ 480 mL/hr
