Study Notes
Measuring and Using Syringes for Medication Administration
- Pharmacists and nurses use various equipment to measure and administer medication, including oral syringes and pipettes.
- It is important to select a device with a measuring capacity equal to or slightly larger than the amount being measured to ensure accuracy.
- Graduates, such as graduated cylinders and conical graduates, are used to measure volume, with graduated cylinders providing more accurate measurements than conical graduates.
- Oral syringes are most accurate for measuring small volumes and are useful for administering medication to children and animals.
- Oral syringes should be used cautiously in an acute care setting to prevent patients from receiving oral medications as injections, which can be fatal.
- Hypodermic syringes are commonly used for sterile compounding to transfer drugs and additives into IV bags and require careful handling to avoid contamination.
- It is important to avoid needle-stick injuries when recapping syringes and to use syringes with safety features, such as safety shields, to improve patient safety.
- Luer locks are used to make secure, leak-free connections between syringes, catheters, and IV lines, ensuring safe administration of medication.
- Syringes should not be touched to avoid contamination, and the correct size syringe should be chosen for drawing up medication to prevent the plunger from becoming dislodged.
- When measuring the volume in a graduate, it is important to read the level at the bottom of the meniscus and avoid shedding particles into the sterile space when opening sterile syringe packages.
- The use of syringes for injecting medication into an IV bag or directly into a vein or catheter is known as an IV push and requires careful handling to ensure accurate administration.
- When measuring volumes, it is crucial to consider the measuring capacity of the graduate and avoid using a graduate for volumes less than 20% of its capacity to minimize measuring errors.

- Hydrolysis reactions can be utilized for prodrugs to release the active drug, for example, acetylsalicylic acid (aspirin) hydrolyzes to salicylic acid and acetic acid.
- Temperature control is crucial for preventing rapid hydrolysis, as higher temperatures accelerate this reaction.
- UV light exposure can cause photolysis and drug degradation, which can be prevented with light protection.
- Drugs sensitive to light exposure include ascorbic acid, folic acid, nitroprusside, and phytonadione injection.
- Other reactions that degrade drugs include isomerization, epimerization, and decarboxylation, which can be prevented by proper storage and handling.
- Excipients such as buffers and preservatives help retain pH and prevent microbial growth, ensuring drug stability.
- Light protection, tightly sealed packaging, and proper storage conditions are essential to prevent degradation from UV light exposure and heat.
- Major excipients like binders, diluents, disintegrants, flavorings, lubricants, and preservatives serve different purposes in drug formulation.
- Excipients like starches, cellulose, and alginates facilitate tablet disintegration and absorption in the small intestine.
- Preservatives, such as alcohols and acids, are crucial for preventing microbial growth in most drug preparations, except for sterile or single-use preparations. Buffers help maintain pH within a certain range to improve stability and solubility.
