A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number).
- A. 21 gtt/min
- B. 20 gtt/min
- C. 25 gtt/min
- D. 18 gtt/min
Correct Answer: A
Rationale: To calculate the IV infusion rate in gtt/min: 1000 mL / 480 min 10 gtt/mL = 20.83 ≈ 21 gtt/min. Therefore, the correct answer is A. Choice B (20 gtt/min) is incorrect because the calculation results in 20.83 gtt/min, rounded to 21. Choices C (25 gtt/min) and D (18 gtt/min) are incorrect as they are not the closest whole number approximation to the calculated value.

A nurse is caring for a client who has a new prescription for amphotericin B. The nurse should plan to monitor the client for which of the following adverse effects?
- A. Hyperkalemia
- B. Hypertension
- C. Constipation
- D. Nephrotoxicity
Correct Answer: D
Rationale: Correct. Amphotericin B is known for its nephrotoxicity, which can lead to kidney damage. Monitoring kidney function is crucial to detect any signs of nephrotoxicity early. Choices A, B, and C are incorrect because hyperkalemia, hypertension, and constipation are not typically associated with amphotericin B use. Therefore, the nurse should focus on monitoring for nephrotoxicity.
A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)
- A. 0.5 mL
- B. 0.005 mL
- C. 0.05 mL
- D. 5 mL
Correct Answer: A
Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.
A client with rheumatoid arthritis is prescribed long-term prednisone therapy. What adverse effect should the client monitor for according to the nurse's instruction?
- A. Stress fractures
- B. Orthostatic hypotension
- C. Gingival ulcerations
- D. Weight loss
Correct Answer: A
Rationale: The correct answer is A: Stress fractures. Long-term prednisone therapy can lead to osteoporosis, which increases the risk of stress fractures. Option B, orthostatic hypotension, is not a common adverse effect associated with prednisone use. Option C, gingival ulcerations, is more commonly associated with conditions like periodontal disease or poor oral hygiene rather than prednisone therapy. Option D, weight loss, is not a typical adverse effect of prednisone; in fact, weight gain is more common due to prednisone's impact on metabolism.
A client with gout is prescribed allopurinol. The nurse should instruct the client to discontinue taking the medication for which of the following adverse effects?
- A. Nausea
- B. Metallic taste
- C. Fever
- D. Drowsiness
Correct Answer: C
Rationale: The correct answer is C: Fever. Fever can indicate a serious hypersensitivity reaction to allopurinol, known as allopurinol hypersensitivity syndrome, which can be severe and even life-threatening. Nausea and drowsiness are common side effects of allopurinol but not necessarily indications to discontinue the medication. Metallic taste is not typically associated with allopurinol use. Therefore, the nurse should emphasize to the client the importance of reporting any signs of fever promptly for further evaluation and management.
A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following indicates she is dehydrated?
- A. Urine specific gravity of 1.035
- B. Urine specific gravity of 444
- C. Urine specific gravity of 2000
- D. Urine specific gravity of 1111.1
Correct Answer: A
Rationale: A urine specific gravity greater than 1.030 indicates dehydration. In this case, a urine specific gravity of 1.035 suggests concentrated urine, indicating dehydration. Choices B, C, and D have values that are not within the normal range for urine specific gravity and do not indicate dehydration. A urine specific gravity of 444, 2000, or 1111.1 are not physiologically possible values and are therefore incorrect.
