A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include a severe allergy to which of the following medications as a contraindication to ceftriaxone?
- A. Gentamicin
- B. Clindamycin
- C. Piperacillin
- D. Sulfamethoxazole-trimethoprim
Correct Answer: C
Rationale: Ceftriaxone is a cephalosporin, and individuals with a penicillin allergy (such as Piperacillin) may have cross-sensitivity, making it contraindicated. Gentamicin (Choice A) belongs to the aminoglycoside class, not related to cephalosporins. Clindamycin (Choice B) is a lincosamide antibiotic and is not typically associated with cross-allergies to cephalosporins. Sulfamethoxazole-trimethoprim (Choice D) is a sulfonamide antibiotic, also not directly related to ceftriaxone.

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 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.
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 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.
