Correct Answer is A
Explanation
A. Use the Z-track technique to administer the medication.: The Z-track technique prevents irritation by sealing the medication within the muscle tissue.
B. Administer the medication with a 27-gauge 1/2-inch needle.: IM injections require a longer needle, typically 1–1.5 inches, and a larger gauge, such as 21–25.
C. Inject the medication at least 5 cm (2 in) from the umbilicus.: This is relevant for subcutaneous injections, not IM injections.
D. Give the medication without aspirating prior to injection.: Aspiration is not always required for IM injections but is often practiced for safety when administering certain medications.
Correct Answer is B
Explanation
A. Tachycardia: Bradycardia, rather than tachycardia, is more typical of opioid toxicity.
B. Sedation: Oxycodone toxicity causes CNS depression, resulting in sedation, respiratory depression, and pinpoint pupils.
C. Dilated pupils: Pinpoint pupils are a classic sign of opioid toxicity.
D. Tachypnea: Respiratory depression, rather than tachypnea, is expected in opioid toxicity.
