The nurse is preparing to administer amantadine 150 mg PO every 12 hours. The available medication is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["15"]
Step 1 is: Find out how many times 50 mg fits into 150 mg 150 ÷ 50 = 3
Step 2 is: Multiply the volume per dose 3 × 5 = 15
Final answer = 15 mL

Correct Answer is C
Explanation
Choice A reason: Cool compresses may provide comfort but are not a primary treatment for acute conjunctivitis, which is often bacterial or viral. They do not address infection or drainage, the main concerns, and are less critical than proper hygiene techniques.
Choice B reason: Topical steroids are not routinely used for acute conjunctivitis, especially bacterial or viral, as they may worsen infections or delay healing by suppressing immune responses. Antibiotics or antivirals are preferred, making this an incorrect teaching point.
Choice C reason: Clearing drainage from the inner to outer aspect of the eye prevents spreading infection across the eye or to the other eye. This technique maintains hygiene, reducing bacterial or viral load in conjunctivitis, making it the most appropriate instruction.
Choice D reason: Patching the eye is not recommended, as it creates a moist environment that can promote bacterial growth or prolong viral conjunctivitis. It may also cause discomfort and is not a standard management strategy for acute conjunctivitis.
Correct Answer is A
Explanation
Choice A reason: A seizure lasting over 5 minutes is considered status epilepticus, a medical emergency requiring immediate intervention to prevent brain hypoxia or injury. Prolonged seizures increase glutamate release, causing excitotoxicity, neuronal damage, and systemic complications like respiratory failure, necessitating urgent 911 response.
Choice B reason: Postictal sleepiness and lethargy are common after generalized seizures due to neuronal exhaustion and temporary metabolic changes in the brain. This is expected and not an emergency unless prolonged or accompanied by other concerning symptoms like respiratory distress.
Choice C reason: Falling at seizure onset is typical in generalized seizures due to loss of muscle control. Unless injury (e.g., head trauma) is suspected, it does not warrant an immediate 911 call, as it is a common seizure manifestation.
Choice D reason: Postictal confusion and slurred speech are normal after a generalized seizure, reflecting temporary cortical dysfunction. These resolve within minutes to hours and do not require emergency services unless persistent or associated with other critical symptoms like unresponsiveness.
