Calculate the dosage using the label below. Round to the nearest tenth place. Order: Celestone, Soluspan (betamethasone) 12 mg IM q24 hr. for 2 doses. Available
0.5 mL sub-cut
1 mL Stat
4 mL IV
2 mL IM
The Correct Answer is D
Rationale:
Ordered Dose:
The prescription is for 12 mg of Celestone Soluspan (betamethasone) IM every 24 hours for 2 doses.
Available Dose (from label): The vial contains 6 mg/mL.
Dosage Calculation: Using the formula:
Volume to administer (mL) = Available concentration (mg/mL) / Ordered dose (mg)
Volume to administer = 12mg / 6mg/mL = 2 mL
Administration Route:
The order specifies IM (intramuscular) administration, aligning with the label instructions.
Thus, 2 mL IM is the correct dosage to administer.

Correct Answer is C
Explanation
Let's calculate the dosage using the provided information.
Information from the label:
Bumetanide concentration: 0.25 mg/mL
Available volume: 10 mL vial
Order: Bumex (bumetanide) 1 mg IV daily
Calculation:
Determine the desired dose: 1 mg
Use the formula:
Desired dose (mg) / Available concentration (mg/mL) = Volume to administer (mL)
Substitute the values:
1 mg / 0.25 mg/mL = Volume to administer (mL)
Calculate:
Volume to administer = 4 mL
Therefore, the correct answer is C. 4 mL
Correct Answer is ["B","C","D","E"]
Explanation
A) Anticoagulants:
Anticoagulants, such as warfarin, heparin, and direct oral anticoagulants (DOACs), are specifically designed to prevent the formation of blood clots or to treat existing clots. They work by interfering with various stages of the clotting cascade, either by inhibiting clotting factors or by enhancing the effects of natural anticoagulants in the body.
B) Antihypertensives:
Antihypertensives, such as ACE inhibitors, beta blockers, and calcium channel blockers, are used to lower high blood pressure by relaxing blood vessels, reducing heart rate, or decreasing fluid retention. While antihypertensives can reduce the overall strain on the heart and blood vessels, they do not have an impact on the clotting process and are not designed to interfere with blood coagulation.
C) Antibiotics:
Antibiotics, such as penicillin or amoxicillin, target bacteria and prevent their growth or kill them, but they do not affect the clotting mechanisms in the blood.
D) Antipyretics:
Antipyretics, such as acetaminophen (Tylenol) or ibuprofen, work by lowering the body's set point temperature in the hypothalamus, helping to relieve fever. They do not affect the clotting cascade or the ability of blood to form clots, so antipyretics are a correct answer.
E) Antiemetics:
Antiemetics, such as ondansetron or metoclopramide, are used to prevent or treat nausea and vomiting. They primarily work by blocking the receptors in the brain that trigger nausea and vomiting but do not have an effect on the clotting process. Thus, antiemetics are a correct answer.
