When adding medications to a bag of intravenous (IV) fluid, the nurse will use which method to mix the solution?
- A. Shaking the bag or bottle vigorously
- B. Turning the bag or bottle gently from side to side
- C. Inverting the bag or bottle one time after injecting the medication
- D. Allowing the IV solution to stand for 10 minutes to enhance even distribution of medication
Correct Answer: B
Rationale: Gently turning the IV bag or bottle from side to side ensures even mixing of the medication without causing bubbles or degradation. The other methods are insufficient or inappropriate.

The nurse will plan to use the Z-track method of intramuscular (IM) injections for which situation?
- A. The medication is known to be irritating to tissues.
- B. The patient is emaciated and has very little muscle mass.
- C. The medication must be absorbed quickly into the tissues.
- D. The patient is obese and has a deep fat layer below the muscle mass.
Correct Answer: A
Rationale: The Z-track method is used for medications that irritate tissues or cause staining, preventing leakage into subcutaneous tissues. It is not specifically for emaciated or obese patients or for rapid absorption.
The nurse is giving an intradermal (ID) injection and will choose which syringe for this injection?
- A. interderm_1.PNG
- B. interderm_2.PNG
- C. interderm_3.PNG
- D. interderm_4.PNG
Correct Answer: B
Rationale: The proper size syringe for ID injection is a 1-mL tuberculin. The other syringes pictured are incorrect. Insulin syringes (marked in units) are not used for intradermal injections.
The nurse needs to administer insulin subcutaneously to an obese patient. Which is the proper technique for this injection?
- A. Using the Z-track method
- B. Inserting the needle at a 5- to 15-degree angle until resistance is felt
- C. Pinching the skin at the injection site, and then inserting the needle to below the tissue fold at a 90-degree angle
- D. Spreading the skin tightly over the injection site, inserting the needle, and then releasing the skin
Correct Answer: C
Rationale: For subcutaneous injections in obese patients, pinching the skin and inserting the needle at a 90-degree angle ensures delivery into the subcutaneous tissue. The Z-track method is for IM injections, a 5- to 15-degree angle is incorrect, and spreading the skin is not appropriate for subcutaneous administration.
When administering medication by IV bolus (push), the nurse will occlude the IV line by which method?
- A. Injecting the bolus without pinching the tubing
- B. Pinching the tubing just above the injection port
- C. Pinching the tubing just below the injection port
- D. Pinching the tubing just above the drip chamber of the infusion set
Correct Answer: B
Rationale: Occluding the IV line by pinching the tubing just above the injection port prevents backflow and ensures the medication is delivered correctly during an IV bolus. The other methods are incorrect.
A patient is receiving eyedrops that contain a beta-blocker medication. The nurse will use what method to reduce systemic effects after administering the eyedrops?
- A. Wiping off excess liquid immediately after instilling the drops
- B. Having the patient close the eye tightly after the drops are instilled
- C. Having the patient try to keep the eye open for 30 seconds after the drops are instilled
- D. Applying gentle pressure to the patient's nasolacrimal duct for 30 to 60 seconds after instilling the drops
Correct Answer: D
Rationale: Applying gentle pressure to the nasolacrimal duct for 30-60 seconds reduces systemic absorption of eyedrops by preventing drainage into the nasal cavity. The other methods do not effectively reduce systemic effects.
