1. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?
- A. Request an order for IV epinephrine to treat anaphylactic shock.
- B. Slow the infusion to 10 mg/min and observe the patient closely.
- C. Stop the infusion and obtain an order for a BUN and serum creatinine.
- D. Suspect Stevens-Johnson syndrome and notify the provider immediately.
Correct answer: B
Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.
2. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?
- A. Administering insulin
- B. Administering IV fluids
- C. Administering oral glucose
- D. Administering oral fluids
Correct answer: A
Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.
3. The nurse is caring for a patient who is receiving furosemide (Lasix) and an aminoglycoside antibiotic. The nurse will be most concerned if the patient reports which symptom?
- A. Dizziness
- B. Dysuria
- C. Nausea
- D. Tinnitus
Correct answer: D
Rationale: The correct answer is D: Tinnitus. When furosemide and an aminoglycoside antibiotic are used together, there is an increased risk of ototoxicity. Tinnitus, a ringing in the ears, is a common early sign of ototoxicity. Dizziness (choice A) is a common side effect of furosemide but not specifically related to this drug interaction. Dysuria (choice B) is painful urination and is not directly associated with this drug combination. Nausea (choice C) is a common side effect of furosemide but is not specifically indicative of ototoxicity caused by the drug interaction.
4. The healthcare professional is reviewing a patient’s chart prior to administering gentamicin (Garamycin) and notes that the last serum peak drug level was 9 mcg/mL and the last trough level was 2 mcg/mL. What action will the healthcare professional take?
- A. Administer the next dose as prescribed.
- B. Obtain repeat peak and trough levels before administering the next dose.
- C. Report potential drug toxicity to the patient’s healthcare provider.
- D. Notify the patient’s healthcare provider of decreased drug therapeutic level.
Correct answer: C
Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient’s healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.
5. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?
- A. Muscle cramps.
- B. Hypertension.
- C. Bradycardia.
- D. Tachycardia.
Correct answer: D
Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.
