Isopropyl alcohol
Bleach
lodine compounds
The Correct Answer is C
A. Glutaraldehyde: Glutaraldehyde is used for high-level disinfection of medical equipment, not for cleaning blood spills.
B. Isopropyl alcohol: While isopropyl alcohol is used for disinfection, it is not the preferred choice for blood spills due to its lower efficacy against certain pathogens.

A. C-reactive protein (CRP): CRP is typically tested using a serum sample collected in a gold or red-top tube, not a light blue tube.
B. Partial thromboplastin time (PTT): PTT is a coagulation test that requires a light blue top tube containing sodium citrate, which acts as an anticoagulant. This tube is specifically used for coagulation studies.
C. Glucose: Glucose levels are commonly measured using a gray-top tube containing sodium fluoride to inhibit glycolysis, not a light blue tube.
D. Lactate: Lactate levels are typically measured using a gray-top tube or green-top tube, depending on the specific protocol, not a light blue tube.

A. Tape measure: A tape measure is necessary to measure the head circumference of infants, which is a routine part of a well-child visit to monitor growth and development.
B. Glucometer: A glucometer is used to measure blood glucose levels and is not routinely required for a well-child visit unless the child has a specific condition like diabetes.
C. Tuning fork: A tuning fork is used to assess hearing, typically in older children or adults, and is not routinely required for a well-child visit for a 1-year-old.
D. Bulb syringe: A bulb syringe may be used for suctioning an infant's nose or mouth, but it is not a standard tool needed for a well-child visit unless there is a specific need.
