A) Social Media:
Social media is not a reliable source for evaluating medication information. Although patients may share their experiences, the information on social media can be anecdotal, unverified, and often lacks scientific evidence. Medical professionals should avoid using social media as a reference for clinical decision-making and instead rely on trusted, evidence-based resources.

B) Wikipedia:
While Wikipedia may offer general overviews of various medications, it is a crowdsourced platform and not a peer-reviewed or professional resource. The information on Wikipedia can be edited by anyone, which raises concerns about accuracy and reliability. While useful for a quick overview, it is not recommended for in-depth medication information or clinical decision-making.

C) Physicians' Desk Reference (PDR):
The Physicians' Desk Reference (PDR) is a well-established, reliable resource for medication information. It includes detailed drug monographs, including indications, dosing, contraindications, adverse effects, and drug interactions. Although it is often considered more of a reference for healthcare providers, it is a trusted and authoritative source for accurate medication information.

D) Lexicomp:
Lexicomp is an evidence-based, reputable resource that provides comprehensive drug information, including dosage recommendations, side effects, interactions, and clinical guidelines. It is frequently used by healthcare providers for decision-making in clinical practice and is considered highly reliable.

E) Micromedex:
Micromedex is another reliable, evidence-based drug information database widely used in healthcare settings. It provides drug monographs, information on drug interactions, adverse effects, and clinical recommendations, making it an essential tool for clinical decision-making.

F) American Hospital Formulary Service (AHFS) Drug Information:
The American Hospital Formulary Service (AHFS) is a trusted source of drug information that is used by healthcare providers to obtain reliable, evidence-based data. It includes detailed monographs on prescription drugs, over-the-counter medications, and other therapeutic agents, which are useful for clinicians when assessing treatment options.

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
