ATI Pharmacology 2 Quiz Questions
Question 1 of 5
A client has been diagnosed with tuberculosis. How long does the nurse anticipate this client will require treatment?
Correct Answer: B
Rationale: The correct answer is B: 6-12 months. Tuberculosis treatment typically involves a combination of antibiotics taken for an extended period to ensure complete eradication of the bacteria. The standard treatment duration for TB is around 6-12 months to prevent relapse and drug resistance. Shorter durations like 2-4 weeks (
C) or 7-10 days (
D) are insufficient to effectively treat TB, leading to treatment failure. A duration of 36 months (
A) is too long and unnecessary for uncomplicated cases, potentially causing patient non-compliance. In summary, the correct answer of 6-12 months is based on the standard treatment guidelines for tuberculosis, providing adequate time for complete recovery and reducing the risk of recurrence.
Question 2 of 5
The term 'virulence' refers to:
Correct Answer: D
Rationale: The term 'virulence' refers to the severity of disease that an organism is able to cause. This is the correct answer because virulence is a measure of how harmful or pathogenic a microorganism is. It is important in understanding the impact of an infectious agent on its host.
Choice A is incorrect as it describes an antibiotic, not virulence.
Choice B refers to genetic changes, not disease severity.
Choice C describes drug resistance, not virulence.
Question 3 of 5
Before starting antimicrobial therapy, the nurse assesses a patient for possible drug allergy. Which of the following complaints should alert the nurse to a drug allergy?
Correct Answer: B
Rationale: The correct answer is B: Hives or shortness of breath. These symptoms are common signs of an allergic reaction to a drug. Hives indicate an immune response causing skin rash, while shortness of breath suggests possible respiratory distress, which can be life-threatening in severe cases. Headaches (
A), diarrhea (
C), and nausea (
D) are common side effects of medications but not specific indicators of an allergic reaction. In summary, hives or shortness of breath are crucial signs of a drug allergy due to their association with immune system response and potential severity compared to other symptoms.
Question 4 of 5
What is the best method of monitoring therapeutic blood levels of vancomycin during therapy?
Correct Answer: C
Rationale: The correct method is C: By obtaining drug peak and trough levels. This is the most accurate way to monitor vancomycin levels as it allows for assessment of the highest (peak) and lowest (trough) concentrations in the blood, ensuring therapeutic levels are maintained without reaching toxic levels. Assessing temperature (
A) or breathlessness (
D) are not specific to monitoring vancomycin levels. Repeating culture and sensitivity tests (
B) is not necessary for monitoring drug levels.
Question 5 of 5
Mr. Carter has been recently started on an antibiotic, and has developed a rash and pruritis. You suspect an allergic reaction and immediately assess him for other more serious symptoms. What question would be most important to ask Mr. Carter?
Correct Answer: A
Rationale: The correct answer is A: "Are you having any difficulty breathing?" This is the most important question to ask Mr. Carter because difficulty breathing could indicate a severe allergic reaction known as anaphylaxis, which can be life-threatening. It is crucial to quickly identify and address this symptom to prevent further complications.
Choices B, C, and D are incorrect because they are not directly related to a severe allergic reaction. Blood in the stool (
B) may indicate gastrointestinal issues, difficulty with hearing (
C) could suggest an ear-related problem, and a headache (
D) could be a common side effect of various conditions but is not typically associated with anaphylaxis. It is essential to focus on the symptom that poses the most immediate danger to the patient's health, which in this case is difficulty breathing.
