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.

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 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 providing teaching to a client who has chronic kidney failure and an AV fistula for hemodialysis with a new prescription for epoetin alfa. Which of the following therapeutic effects of epoetin alfa should the nurse include in the teaching?
- A. Reduces blood pressure
- B. Inhibits clotting of fistula
- C. Promotes RBC production
- D. Stimulates growth of neutrophils
Correct Answer: C
Rationale: The correct answer is C: Promotes RBC production. Epoetin alfa stimulates red blood cell production, which is important for clients with chronic kidney disease who may have anemia due to decreased erythropoietin production by the kidneys. Options A, B, and D are incorrect: epoetin alfa does not directly reduce blood pressure, inhibit clotting of the fistula, or stimulate growth of neutrophils.
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 healthcare provider is assessing a client who is receiving IV gentamicin three times daily. Which of the following findings indicates that the client is experiencing an adverse effect of this medication?
- A. Hypoglycemia
- B. Proteinuria
- C. Nasal congestion
- D. Visual disturbances
Correct Answer: B
Rationale: Corrected Rationale: Gentamicin is known to cause nephrotoxicity as an adverse effect. Proteinuria, which is the presence of excess proteins in the urine, may indicate kidney damage from the medication. Monitoring renal function is crucial in clients receiving gentamicin. Choice A, hypoglycemia, is not a typical adverse effect of gentamicin. Choices C and D, nasal congestion and visual disturbances, are not commonly associated with gentamicin use or its adverse effects.
