Which drug group inhibits the formation of clots?

A.

Antibiotics

B.

Analgesics

C.

Antidepressants

D.

Anticoagulants

Answer and Explanation

The Correct Answer is D

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

Given:

Ordered dose of Lithium: 300 mg

Available Lithium capsules: 150 mg/capsule

Step 1: Calculate the number of capsules required:

Number of capsules = Desired dose (mg) / Strength of each capsule (mg/capsule)

Number of capsules = 300 mg / 150 mg/capsule

Number of capsules = 2 capsules

Correct Answer is D

Explanation

Ordered dose of 0.9% Sodium Chloride: 20 mL/kg

Child's weight: 55 lbs

Infusion time: 6 hours

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg

Step 2: Calculate the total volume of 0.9% Sodium Chloride:

Total volume (mL) = Ordered dose (mL/kg) x Child's weight (kg)

Total volume (mL) = 20 mL/kg x 24.94756 kg

Total volume (mL) = 498.9512 mL

Step 3: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Infusion rate (mL/hr) = 498.9512 mL / 6 hr

Infusion rate (mL/hr) = 83.15853333 mL/hr

Step 4: Round to the nearest whole number:

Infusion rate (mL/hr) ≈ 83 mL/hr
