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
Explanation
A) 0.2 mg
The correct way to write the dosage is 0.2 mg. In pharmacology and medication administration, it is important to follow the guidelines set by the Institute for Safe Medication Practices (ISMP) and other standard bodies, which recommend that a leading zero be used before a decimal point. This helps to prevent errors in interpreting the dosage. Writing 0.2 mg clearly indicates two-tenths of a milligram, and the leading zero makes it easier to avoid misreading the dose as a whole number (2.0 mg) or omitting the decimal point entirely.
B) .2 mg
Writing the dosage as .2 mg (without the leading zero) is considered unsafe and is a poor practice. The absence of the leading zero before the decimal point increases the likelihood that the dose may be misread. For example, someone could confuse .2 mg with 2.0 mg or misinterpret it in a hurried situation, which could lead to a tenfold dosing error
C) 2.0 mg
Writing 2.0 mg would indicate two milligrams, which is not the correct dosage for "two-tenths of a milligram." While this format does use a decimal point, it does not represent the correct dose. This error could lead to an overdose if misread as a whole number.
D) 0.20 mg
While 0.20 mg is technically correct, it is not the preferred or necessary format. The use of two decimal places is unnecessary in this case. Since the dosage is two-tenths of a milligram, 0.2 mg is simpler and clearer. Using an unnecessary trailing zero (the second "0") can cause confusion or misinterpretation, especially in critical settings where every detail counts.
Correct Answer is B
Explanation
A) "If I develop new symptoms like severe diarrhea, I should ignore them and finish the antibiotics."
New symptoms like severe diarrhea, especially if it is watery or bloody, can be a sign of a superinfection, such as Clostridium difficile (C. diff), which is associated with antibiotic use. It is essential for the client to report these symptoms to their healthcare provider immediately. Ignoring such symptoms can lead to serious complications.
B) "I need to finish all my antibiotics and report any unusual symptoms like a white coating on my tongue to my doctor."
Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. The white coating on the tongue could indicate a fungal superinfection, such as oral thrush, which requires medical attention. This statement demonstrates an understanding of the importance of finishing antibiotics and recognizing potential side effects or superinfections.
C) "It is okay to share my antibiotics with family members if they have similar symptoms to mine."
Antibiotics should never be shared with others, even if they have similar symptoms. The antibiotics prescribed to a client are tailored to treat their specific infection, and taking the wrong antibiotic can lead to ineffective treatment, drug resistance, or adverse reactions. Sharing medication is dangerous and illegal.
D) "I should stop taking the antibiotics as soon as I feel better to avoid any side effects."
It is important to complete the full course of antibiotics as prescribed, even if the client starts feeling better before the course is finished. Stopping antibiotics prematurely can result in the infection not being fully treated, leading to a relapse or the development of antibiotic-resistant bacteria.
