Answer to Question 1
D
Feedback:
Nurses bunch tissue between the thumb and fingers before administering the injection to avoid instilling medication within the muscle. Bunching does not prevent needle-stick injuries, it does not facilitate blood circulation at the injection site, nor does it ensure the accuracy of landmarking.
Answer to Question 2
A
Feedback:
Heparin dosages are very small volumes; hence, they may require a tuberculin syringe to ensure accuracy. Conventional syringes and needles are being redesigned to avoid needle-stick injuries and ensure accuracy. Insulin syringes are specially designed to prepare insulin dosages. A syringe calibrated in 0.2 ml is used in 3 or 5 ml dosages for an intramuscular injection.
