A nurse is preparing to administer ampicillin 500 mg in 50 mL of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver?
- A. 30 gtt/min
- B. 32 gtt/min
- C. 33 gtt/min
- D. 35 gtt/min
Correct Answer: C
Rationale: Calculation: 10 gtt/mL 50 mL · 15 min = 33.33, rounded to 33 gtt/min. This ensures proper delivery of the medication over the prescribed time. Choice A is incorrect because it does not factor in the precise calculation based on the given data. Choice B is incorrect as it does not reflect the accurate rate of infusion required. Choice D is incorrect as it does not align with the correct calculation based on the drop factor and infusion parameters provided in the question.

A nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr?
- A. 60 mL/hr
- B. 62 mL/hr
- C. 63 mL/hr
- D. 65 mL/hr
Correct Answer: C
Rationale: Calculation: 250 mL / 4 hours = 62.5 mL/hr, which should be rounded up to 63 mL/hr. This ensures the correct rate is set for continuous feeding. Choice A (60 mL/hr) is incorrect as it does not reflect the accurate calculation. Choice B (62 mL/hr) is close but does not round up to the nearest whole number as required. Choice D (65 mL/hr) is higher than the correct calculation and would deliver the feeding solution at a faster rate than prescribed.
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?
- A. 19 gtt/min
- B. 20 gtt/min
- C. 21 gtt/min
- D. 22 gtt/min
Correct Answer: C
Rationale: Calculation: 1000 mL / 480 minutes 10 gtt/mL = 20.83, rounded to 21 gtt/min. This ensures proper IV fluid administration over the prescribed time. Choice C is the correct answer as it reflects the accurate calculation based on the given parameters. Choice A is incorrect because it does not accurately calculate the infusion rate. Choice B is incorrect as it does not consider the precise calculation required. Choice D is incorrect as it deviates from the correct calculation.
A nurse is reviewing the laboratory results for a client who has a prescription for filgrastim. The nurse should recognize that an increase in which of the following values indicates a therapeutic effect of this medication?
- A. Erythrocyte count
- B. Neutrophil count
- C. Lymphocyte count
- D. Thrombocyte count
Correct Answer: B
Rationale: Filgrastim is used to increase neutrophil production in clients undergoing chemotherapy or with bone marrow suppression. A rise in neutrophil count indicates the medication is working effectively to boost immune response. Choices A, C, and D are incorrect as filgrastim primarily targets neutrophils, not erythrocytes, lymphocytes, or thrombocytes.
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?
- A. 0.2 mL
- B. 0.5 mL
- C. 1.0 mL
- D. 1.5 mL
Correct Answer: B
Rationale: To determine the volume of prochlorperazine to administer, divide the prescribed dose (2.5 mg) by the concentration of the medication (5 mg/mL). This calculation results in 0.5 mL. Therefore, the nurse should administer 0.5 mL to deliver the correct dose. Choice A (0.2 mL) is incorrect as it miscalculates the dosage. Choices C (1.0 mL) and D (1.5 mL) are also incorrect as they do not accurately reflect the calculated volume needed for the dose.
A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?
- A. 0.7 mL
- B. 0.8 mL
- C. 1.0 mL
- D. 1.2 mL
Correct Answer: B
Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.
