Full Explanation
To calculate the volume of fluoxetine to administer, we need to use the formula for dose conversion.
Step 1 is to set up the equation: 30 mg (desired dose) ÷ (20 mg/5 mL). This simplifies to 30 mg × (5 mL/20 mg). The mg units cancel out, leaving us with the volume in mL.
So, the correct answer is 7.5 mL.
Similar Questions
A nurse is reinforcing dietary teaching for a client who is to start taking a monoamine oxidase inhibitor (MAOI). Which of the following food choices should the nurse identify as having the highest tyramine content?.
A. 2% milk.
Milk, especially when fresh and not aged, is generally low in tyramine. The tyramine content in milk does not significantly increase unless the milk is fermented or nearing expiration. Therefore, 2 % milk is considered a safe option for individuals taking MAOIs.
B. Sliced apples.
Fresh fruits like apples are typically low in tyramine. However, as fruits ripen or become overripe, their tyramine content can increase. Since the question specifies “sliced apples,” which are likely to be fresh, they would not have a high tyramine content and are considered safe for someone on MAOIs.
C. Avocados.
Avocados, particularly if they are overripe, contain higher levels of tyramine compared to other foods listed. Overripe avocados can have a tyramine content that is high enough to be of concern for individuals taking MAOIs, making them the food choice with the highest tyramine content among the options provided.
D. Celery sticks.
Celery is a low-tyramine food and is safe for consumption by individuals on MAOI therapy. There is no significant increase in tyramine content in celery, even as it ages, making it a suitable option for those with dietary restrictions related to MAOIs.
Full Explanation
The correct answer is: C. Avocados.
Choice A reason: Milk, especially when fresh and not aged, is generally low in tyramine. The tyramine content in milk does not significantly increase unless the milk is fermented or nearing expiration. Therefore, 2 % milk is considered a safe option for individuals taking MAOIs.
Choice B reason: Fresh fruits like apples are typically low in tyramine. However, as fruits ripen or become overripe, their tyramine content can increase. Since the question specifies “sliced apples,” which are likely to be fresh, they would not have a high tyramine content and are considered safe for someone on MAOIs.
Choice C reason: Avocados, particularly if they are overripe, contain higher levels of tyramine compared to other foods listed. Overripe avocados can have a tyramine content that is high enough to be of concern for individuals taking MAOIs, making them the food choice with the highest tyramine content among the options provided.
Choice D reason: Celery is a low-tyramine food and is safe for consumption by individuals on MAOI therapy. There is no significant increase in tyramine content in celery, even as it ages, making it a suitable option for those with dietary restrictions related to MAOIs.
A nurse is preparing to administer valproic acid 500 mg PO. Available is valproic acid oral solution 250 mg/5 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number.)
Full Explanation
Step 1: Determine the Medication Concentration
- The total amount of medication in the solution is 250 mg.
- The total volume of the solution is 5 mL.
- To find the concentration per mL:
250 mg ÷ 5 mL = 50 mg/mL
Step 2: Determine the Required Volume
- The prescribed dose is 500 mg.
- To find the volume needed:
500 mg ÷ 50 mg/mL = 10 mL
Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.
A nurse is monitoring a client's IV site.
The nurse should report which of the following findings as manifestations of phlebitis? (Select all that apply.).
A. Blistering around the insertion site.
Blistering around the insertion site is not a common sign of phlebitis. It could indicate a more severe complication like extravasation or infiltration.
B. Streak formation along the vein.
Streak formation along the vein is a classic sign of phlebitis. It indicates inflammation and possible infection.
C. Erythema at the insertion site.
Erythema at the insertion site is another common sign of phlebitis. It indicates inflammation.
D. Warmth at insertion site.
Warmth at the insertion site is also a common sign of phlebitis. It is caused by increased blood flow to the area due to inflammation. So, the correct answers are B, C, and D.
Full Explanation
Choice A rationale:
Blistering around the insertion site is not a common sign of phlebitis. It could indicate a more severe complication like extravasation or infiltration.
Choice B rationale:
Streak formation along the vein is a classic sign of phlebitis. It indicates inflammation and possible infection.
Choice C rationale:
Erythema at the insertion site is another common sign of phlebitis. It indicates inflammation.
Choice D rationale:
Warmth at the insertion site is also a common sign of phlebitis. It is caused by increased blood flow to the area due to inflammation. So, the correct answers are B, C, and D.
