A nurse is preparing to administer lactated Ringer's 1,500 mL IV to infuse at 50 mL/hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["13"]
gtt/min = (mL/hr x gtt/mL) / 60
gtt/min = (50 x 15) / 60 gtt/min = 750 / 60 gtt/min = 12.5 Rounding to the nearest whole number, the answer is 13.
Therefore, the nurse should set the manual IV infusion to deliver 13 gtt/min.

Correct Answer is A
Explanation
- A is correct because facilitating an interdisciplinary conference at the new facility for the family can help address their concerns, provide information about the client's plan of care, and promote continuity of care.
- B is incorrect because referring the client and family to a social worker for assistance and a follow-up meeting is not enough to address their immediate concerns and does not involve other members of the health care team.
- C is incorrect because reassuring the client's family that the same provider will provide care at the new facility may not be true and does not address their specific concerns about the level of care.
- D is incorrect because telling the family that the rehabilitation facility has an excellent client care record is not enough to address their specific concerns and may sound dismissive.
Correct Answer is C
Explanation
- A. Incorrect. A 1-inch needle may not be long enough to reach the muscle layer in an obese client, which may result in subcutaneous injection and reduced absorption of the medication.
- B. Incorrect. A 45° angle may not be appropriate for an IM injection, as it may cause the needle to enter at an oblique angle and miss the muscle layer or hit a bone or nerve.
- C. Correct. The ventrogluteal site is preferred for IM injections in obese clients, as it has less subcutaneous fat and a large muscle mass that can accommodate larger volumes of medication.
- D. Incorrect. Pinching the skin up during injection may cause the needle to enter at a shallow angle and deposit the medication in the subcutaneous tissue instead of the muscle layer.
