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?
Select an injection site that is free of scar tissue.
Massage the site following the injection.
Hold the needle at a 30 angle during injection
Inject 0.3 to 0.5 mL of the solution.
The Correct Answer is A
A. When administering a TST, the nurse should select an injection site that is free of scar tissue and areas with excessive hair, veins, or visible lesions. The preferred site for TST administration is the volar aspect of the forearm, approximately 2-4 inches below the elbow.
B. After administering the TST, the nurse should not massage or manipulate the injection site. Massaging the site can cause irritation or spread the solution, leading to inaccurate results.
C. he TST is administered intradermally, typically with a 27-gauge needle. The needle should be inserted with the bevel facing upward at a 5-15-degree angle.
D. The standard dose of tuberculin solution (e.g., purified protein derivative, PPD) for a TST is 0.1 mL containing 5 tuberculin units (TU).

Correct Answer is A
Explanation
A. Increased respiratory rate is a sign that naloxone is effectively reversing opioid-induced respiratory depression. Opioids can suppress the respiratory drive, leading to hypoventilation or respiratory arrest. Naloxone works by competitively binding to opioid receptors and displacing opioids, thereby restoring normal respiratory function.
B. Increased temperature is not a direct effect of naloxone administration. Naloxone primarily reverses the central nervous system depressant effects of opioids, including respiratory depression and sedation, rather than affecting body temperature.
C. Naloxone does not directly affect pain perception. Its primary action is to reverse the respiratory depression and central nervous system depression caused by opioids. While the client may experience pain relief indirectly as a result of improved respiratory function and consciousness, naloxone itself does not directly reduce pain.
D. Decreased blood pressure is not a direct effect of naloxone administration. Naloxone primarily reverses the respiratory and central nervous system depressant effects of opioids, rather than affecting blood pressure directly.
Correct Answer is A
Explanation
A. Garlic may potentiate the effects of warfarin, an anticoagulant medication. When taken together, garlic can increase the risk of bleeding due to its antiplatelet properties, potentially leading to an increased risk of bruising or bleeding episodes.
B. Hydrochlorothiazide is a diuretic medication used to treat hypertension and edema. There is no known significant interaction between hydrochlorothiazide and garlic.
C. Dicloxacillin is an antibiotic medication from the penicillin class. There is no known significant interaction between dicloxacillin and garlic.
