A patient has been taking ergotamine to relieve their migraines. Which of the following adverse effects would indicate to the nurse that the drug may have entered into toxic levels?
Diarrhea
Delirium
Hypotension
Bradycardia
The Correct Answer is B
A. Diarrhea is not typically associated with ergotamine toxicity. Gastrointestinal symptoms such as nausea and vomiting are more common adverse effects of ergotamine use.
B. Delirium is a potential sign of ergotamine toxicity. At toxic levels, ergotamine can cause central nervous system symptoms such as confusion, hallucinations, and delirium.
C. Hypotension may occur as an adverse effect of ergotamine due to its vasoconstrictive properties. However, hypotension alone may not indicate ergotamine toxicity.
D. Bradycardia is not a typical adverse effect of ergotamine. Ergotamine is more commonly associated with vasoconstriction and can lead to hypertension or tachycardia rather than bradycardia.

Correct Answer is A
Explanation
A. Getting up slowly from a sitting or lying position is an important aspect of patient education for individuals taking tamsulosin, as this medication can cause orthostatic hypotension, leading to dizziness or fainting upon standing up quickly.
B. Tamsulosin is often taken once daily, approximately 30 minutes after the same meal each day, typically breakfast or the first meal of the day. Taking it with breakfast is not a requirement for
its efficacy.
C. There is no need to restrict fluids while on tamsulosin therapy. In fact, adequate hydration is generally encouraged.
D. Tamsulosin is not typically associated with causing hypertension. Instead, it is more commonly associated with hypotension, especially orthostatic hypotension.
Correct Answer is ["0.6"]
Explanation
To find out how many milliliters (mL) of methylnaltrexone should be administered to achieve a dose of 12 mg, we need to set up a proportion based on the available concentration.
Given:
- Methylnaltrexone concentration: 8 mg per 0.4 mL
- Desired dose: 12 mg
We can set up the proportion as follows:
8 /0.4 = 12 / x
Where ( x ) is the unknown amount of methylnaltrexone in milliliters.
To solve for ( x ), we can cross multiply and then divide:
8x = 0.4 12
8x = 4.8
x = 4.8/8
x = 0.6
Therefore, the nurse should administer 0.6 mL of methylnaltrexone.
