Which drug groups do not inhibit clot formation? (SELECT ALL THAT APPLY)

Anticoagulants

Antihypertensives

Antibiotics

Antipyretics

Antiemetics

Answer and Explanation

Correct Answer : B,C,D,E

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.

Correct Answer is D

Explanation

Convert ounces to millilitres (1 oz = 29.5735 mL):

6oz×29.5735mL/oz=177.441mL6

Calculate the frequency of doses per day:

The patient receives a dose every 4 hours, so in 24 hours, the number of doses is:

24hours/4hours/dose=6doses

Calculate the total volume for all doses:

177.441mL/dose×6doses=1064.646mL

Rounding to the nearest whole number=1080 mL

A. 9 B. 19 C. 0.9 D. 90

Correct Answer is A

Explanation

Convert the dosage to mcg per hour:

15mcg/min×60min/hr=900mcg/hr15

Convert the available nitroglycerin concentration to mcg/mL:

25mg=25,000mcg

Theconcentrationis(25,000mcg/250mL)=100mcg

Calculate the flow rate in mL per hour using the dosage and concentration:

Flowrate(mL/hr)=(900mcg/hr100mcg/mL)=9mL/hr
