A patient is experiencing status epileptics. The nurse anticipates immediate administration of which drug?
Diazepam
Phenobarbital
Valproic acid
Phenytoin
The Correct Answer is A
A) Diazepam
Diazepam (a benzodiazepine) is the first-line treatment for status epilepticus, especially in emergency situations. It works by quickly calming overactive electrical activity in the brain and can be administered intravenously for rapid effect. Diazepam is commonly given as an initial treatment due to its fast onset of action in stopping seizures.
B) Phenobarbital
Phenobarbital is an anticonvulsant that can also be used for seizures, but it is typically used in cases where seizures persist after initial treatment, or as a long-term maintenance therapy. It is not the first-line drug for status epilepticus and is typically administered after other options like diazepam have been tried.
C) Valproic acid
Valproic acid is an anticonvulsant used for chronic seizure management (like for generalized seizures and some focal seizures), but it is not typically used as the immediate treatment in status epilepticus. It may be used in the long-term management or when other drugs fail, but diazepam or lorazepam are preferred for immediate control of seizures.
D) Phenytoin
Phenytoin is another commonly used anticonvulsant, but it has a slower onset of action compared to benzodiazepines like diazepam. While phenytoin is often used for long-term seizure prevention, it is not the most immediate choice in an emergency setting. After initial seizure control with a benzodiazepine, phenytoin may be given for continued seizure prevention.

Correct Answer is ["A","B","D","E"]
Explanation
A) Subcutaneous:
The subcutaneous route involves administering medication into the layer of fat and connective tissue beneath the skin. This method is used for drugs that require slower absorption, such as insulin or certain vaccines.
B) Intramuscular:
The intramuscular route involves injecting medication directly into a muscle. This allows for faster absorption compared to subcutaneous injections, making it ideal for drugs that need to be absorbed quickly, such as vaccines or certain antibiotics.
C) Via a nasogastric tube:
Administering drugs via a nasogastric tube is not considered a parenteral route. The nasogastric (NG) tube delivers medications directly into the stomach via the gastrointestinal tract, which is not part of the parenteral system. Parenteral routes are those that bypass the digestive system, like injections.
D) Intradermal:
The intradermal route involves injecting medication just under the skin, in the dermis. This is typically used for allergy testing or tuberculosis screenings. It is a parenteral route because it bypasses the digestive system.
E) Intravenous:
The intravenous route involves injecting medication directly into a vein, offering rapid absorption and fast onset of action. This method is ideal for critical or emergency situations where immediate medication effects are necessary.
Correct Answer is D
Explanation
Identify the desired dose and the available concentration:
Desired dose: 5 mg of hydrocodone
Available concentration: 7.5 mg of hydrocodone in 15 mL of elixir
Calculate the volume needed for the desired dose using the formula:
Volume(mL)=(Desireddose(mg)/Availableconcentration(mg/mL))
Determine the available concentration in mg/mL:
Availableconcentration=(7.5mg/15mL)=0.5mg/mL
Calculate the volume needed for a 5 mg dose:
Volume(mL)=(5mg/0.5mg/mL)=10mL
