Question 1 of 5
When preparing to administer an intradermal injection to an adult, the nurse ensures that the dose amount does not exceed 0.1 mL. A 1 mL tuberculin syringe is used with a 25-gauge needle and is administered at which angle?
Correct Answer: B
Rationale: The correct answer is B: 15-degree angle. When administering an intradermal injection with a 1 mL tuberculin syringe, a 25-gauge needle, and a maximum dose of 0.1 mL, the needle should be inserted at a 15-degree angle. This angle allows for the medication to be injected into the dermis layer, just beneath the epidermis, ensuring proper absorption. A 12-degree angle (choice
A) may not reach the dermis layer effectively. A 30-degree angle (choice
C) is too steep and may result in the medication being deposited too deep. A 45-degree angle (choice
D) is used for subcutaneous injections, not intradermal injections.
Question 2 of 5
The graduate nurse is aware that the count of the unit's narcotics and controlled substances at the change of shifts should involve:
Correct Answer: A
Rationale:
Rationale: The correct answer is A because involving both the nurse going off duty and the nurse coming on duty ensures a complete and accurate count of narcotics and controlled substances. This practice promotes accountability and transparency in the medication management process. Option B is incorrect as the pharmacist is not directly involved in the shift change count. Option C is incorrect as it may not be feasible for everyone to be present during the shift change. Option D is incorrect as involving a pharmacy technician may not align with unit protocols.
Question 3 of 5
The physician orders Zestril 15 mg po daily for hypertension. The medication is supplied in 5-mg tablets. How many tablets will the nurse administer?
Correct Answer: C
Rationale:
To calculate the number of tablets, divide the total dose by the dose per tablet. In this case, 15 mg ÷ 5 mg = 3 tablets. Option C is correct. Option A is incorrect as it does not cover the total dose. Option B is incorrect as it is only half of the total dose. Option D is incorrect as it exceeds the total dose.
Question 4 of 5
Which pain medication may be administered to the patient as needed?
Correct Answer: D
Rationale: The correct answer is D: Ketorolac 10 mg IV every 4 hours as needed. Ketorolac is a short-acting NSAID suitable for as-needed pain relief. It is an appropriate choice for acute pain management due to its rapid onset of action and effectiveness. The other choices are not ideal for as-needed use. A: Fentanyl patch is a long-acting opioid for chronic pain, not suitable for immediate needs. B: Acetaminophen with oxycodone is a combination for moderate to severe pain but not ideal for as-needed dosing. C: Morphine extended-release is a long-acting opioid for chronic pain, not suitable for as-needed use.
Question 5 of 5
The nurse is to administer the patient's next dose of vancomycin at 9:30 a.m. What time will the nurse draw the patient's blood to check the trough vancomycin level?
Correct Answer: B
Rationale: The correct answer is B: 9:00 a.m. The nurse should draw the trough vancomycin level 30 minutes before the next dose is due. Since the next dose is scheduled at 9:30 a.m., the blood should be drawn at 9:00 a.m. This timing allows for an accurate assessment of the vancomycin level in the patient's bloodstream, ensuring appropriate dosing adjustments if needed.
Choices A, C, and D are incorrect because drawing the blood at those times would not align with the recommended 30-minute pre-dose timeframe for trough levels.
