Calculate the following dosage using ratio and proportions method. Round answers to the nearest tenth. Order: Tegretol 200 mg p.o.t.i.d.
Available
3 tabs
2 tabs
1 1/2 tabs
4 tabs
The Correct Answer is B
Calculate the dosage using the ratio and proportion:
Given:
Order: 200 mg p.o. t.i.d.
Available: Tegretol 100 mg chewable tablets.
Step 1: Set up the proportion
Available dose (100 mg) : 1 tablet = Ordered dose (200 mg) : x tablets
Step 2: Solve for 𝑥
100 mg : 1 tab = 200 mg : 𝑥 tabs
𝑥 = 200/100 = 2 tablets

Correct Answer is D
Explanation
A) Antibiotics
Antibiotics are medications used to treat infections by killing or inhibiting the growth of bacteria. They do not have any direct effect on clot formation. Antibiotics work by targeting specific parts of bacterial cells, such as cell walls, proteins, or DNA, but they do not interfere with the blood coagulation system. Therefore, antibiotics are not a drug group that inhibits clot formation.
B) Analgesics
Analgesics are pain-relieving medications used to reduce pain, and they include both non-opioid (e.g., acetaminophen, NSAIDs) and opioid medications (e.g., morphine, oxycodone). While some analgesics, particularly nonsteroidal anti-inflammatory drugs (NSAIDs), can affect platelet function and may slightly influence clotting, their primary function is to relieve pain.
C) Antidepressants
Antidepressants are medications used to treat mood disorders, including depression, anxiety, and other psychiatric conditions. These drugs work by altering the balance of neurotransmitters in the brain, such as serotonin, norepinephrine, or dopamine. Antidepressants do not directly affect blood clotting mechanisms, although some classes, such as selective serotonin reuptake inhibitors (SSRIs), can have mild anticoagulant effects due to their impact on platelet aggregation.
D) Anticoagulants
Anticoagulants inhibit the coagulation cascade, a series of complex biochemical reactions that lead to the formation of a blood clot. Common examples of anticoagulants include warfarin, heparin, and the newer direct oral anticoagulants (DOACs) such as rivaroxaban and apixaban. Anticoagulants are primarily used to reduce the risk of clot formation in conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), and atrial fibrillation (AF), and they are essential in managing and preventing clot-related complications.
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
