A medical assistant is preparing an examination room for a 1-year-old patient's well-child visit. Which of the following supplies should the assistant ensure is in examination room?
Tape measure
Glucometer
Tuning fork
Bulb syringe
The Correct Answer is A
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.

Correct Answer is C
Explanation
A. Bevel up with a 45° angle: A 45° angle is too steep for venipuncture; this angle is typically used for intramuscular injections.
B. Bevel down with a 45° angle: Bevel down is incorrect for venipuncture as it increases the risk of the needle piercing through the vein.
C. Bevel up with a 15° angle: This is the correct technique for venipuncture. The needle should be inserted at a 15° to 30° angle, with the bevel facing up to ensure smooth entry into the vein and minimize discomfort.
D. Bevel down with a 15° angle: Bevel down is not recommended for venipuncture because it can cause the needle to catch on the vein wall, increasing the risk of injury or complications.
Correct Answer is B
Explanation
A. 1:5: This ratio would create a stronger solution than typically recommended for disinfection, which might not be necessary and could be harsh on equipment.
B. 1:10: A 1:10 dilution of bleach to water is commonly used for disinfecting surfaces and cleaning medical equipment, as it provides effective disinfection while being safe for equipment.
C. 1:15: This dilution might not be strong enough to ensure effective disinfection.
D. 1:20: This ratio is even more diluted and may not provide adequate disinfectant strength for cleaning purposes.
