Calculate the flow rate in mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 100 mL 0.45% NS in 45 min by infusion pump. Calculate rate in ml/hr
133 mL/hr
13.3 mL/hr
130 mL/hr
13 ml/hr
The Correct Answer is A
Given:
Volume of fluid: 100 mL
Infusion time: 45 minutes
Step 1: Convert infusion time to hours:
Infusion time (hr) = 45 min / 60 min/hr
Infusion time (hr) = 0.75 hr
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 100 mL / 0.75 hr
Flow rate (mL/hr) = 133.3333333 mL/hr
Step 3: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 133 mL/hr

Correct Answer is C
Explanation
Given:
Ordered dose of acetaminophen: 10 mg/kg
Child's weight: 22 lb
Concentration of acetaminophen liquid: 160 mg/5 mL
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 22 lbs x 0.453592 kg/lb = 9.976824 kg
Step 2: Calculate the total dose of acetaminophen:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 10 mg/kg x 9.976824 kg
Total dose (mg) = 99.76824 mg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total dose (mg) / Concentration (mg/mL)
Volume (mL) = 99.76824 mg / 160 mg/5 mL
Volume (mL) = 99.76824 mg x (5 mL / 160 mg)
Volume (mL) = 3.1177575 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 3.1 mL
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.
