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 caring for a client who has congestive heart failure and is taking digoxin. The client reports nausea and refuses to eat breakfast. Which of the following actions should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray
- B. Administer an antiemetic
- C. Inform the client's provider
- D. Check the client's apical pulse
Correct Answer: D
Rationale: The correct answer is to check the client's apical pulse first. Nausea can be a sign of digoxin toxicity, and assessing the client's heart rate is crucial in this situation. Administering an antiemetic or encouraging the client to eat should come after ensuring the client's safety. While informing the provider is important, the immediate concern is to assess for potential digoxin toxicity by checking the client's apical pulse.
A client at 28 weeks of gestation is experiencing preterm labor. Which of the following medications should the nurse plan to administer?
- A. Oxytocin
- B. Nifedipine
- C. Dinoprostone
- D. Misoprostol
Correct Answer: B
Rationale: Nifedipine is the correct choice in this scenario. It is a calcium channel blocker that helps suppress uterine contractions and halt preterm labor. Nifedipine is commonly used to manage preterm labor in pregnant women by relaxing the smooth muscle of the uterus. Oxytocin (Choice A) is used to induce or augment labor, not to inhibit contractions. Dinoprostone (Choice C) and Misoprostol (Choice D) are prostaglandins used for cervical ripening and induction of labor, not for stopping preterm labor.
A nurse is caring for a client who is receiving IV diltiazem for atrial fibrillation. Which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct Answer: A
Rationale: The correct answer is A: Hypotension. Diltiazem can cause further lowering of blood pressure, so it should not be administered if the client is already hypotensive. Monitoring blood pressure is crucial before giving diltiazem. Choice B, tachycardia, is not a contraindication for diltiazem use; in fact, diltiazem is used to slow down the heart rate. Choice C, decreased level of consciousness, may indicate other issues but is not a direct contraindication for diltiazem. Choice D, history of diuretic use, is not a contraindication by itself; however, caution should be exercised when diltiazem is given with diuretics due to potential interactions.
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 planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. How many mL should the nurse administer per dose? (Round to the nearest tenth)
- A. 2.6 mL
- B. 2.2 mL
- C. 3.5 mL
- D. 5.0 mL
Correct Answer: A
Rationale: The correct calculation is as follows: The toddler's weight in kg is 13 kg (28.6 lb / 2.2 lb/kg). The total daily dose is 260 mg (20 mg x 13 kg). Therefore, the dose per administration is 130 mg (260 mg / 2). Given the concentration of 250 mg/5 mL, the dose in mL is 2.6 mL (130 mg / (250 mg/5 mL)). Therefore, the nurse should administer 2.6 mL per dose. Choice B, 2.2 mL, is incorrect as it does not reflect the correct calculation. Choices C and D, 3.5 mL and 5.0 mL, are also incorrect and do not align with the accurate dosage calculation based on the given scenario.
