A nurse is planning to administer a tuberculin skin test to a client who has had an exposure to tuberculosis. Which of the following actions should the nurse plan to take?
Inject 0.3 to 0.5 mL of the solution.
Select an injection site that is free of scar tissue.
Hold the needle at a 30° angle during injection.
Massage the site following the injection.
The Correct Answer is B
A. Inject 0.3 to 0.5 mL of the solution: The typical volume for a tuberculin skin test is 0.1 mL.
B. Select an injection site that is free of scar tissue: Scar tissue can interfere with the reading of the tuberculin skin test, so a site free of scars should be selected.
C. Hold the needle at a 30° angle during injection: The needle should be held at a 5–15° angle for intradermal injections.
D. Massage the site following the injection: Massaging the site is not recommended as it could affect the accuracy of the test.

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.
Correct Answer is C
Explanation
A. Administer the insulin using a tuberculin syringe at a 15° angle: Tuberculin syringes are used for intradermal injections, not subcutaneous injections, and insulin is typically administered at a 90° angle.
B. Rapidly inject the insulin using a 20-gauge 1-inch needle: A 20-gauge needle is too large for insulin injections, which typically use smaller needles (e.g., 25- to 30-gauge).
C. Insert the needle into the right thigh at a 90° angle: Insulin injections are typically administered subcutaneously at a 90° angle, and the thigh is a common injection site.
D. Slowly inject the insulin using the Z-track method: The Z-track method is not used for insulin injections, which are administered subcutaneously, not intramuscularly.
