1. Which of the following tests is recommended for lung cancer screening?
- A. Chest X-ray
- B. Pulmonary function test
- C. Computed tomography (CT) scan
- D. Magnetic resonance imaging
Correct answer: Computed tomography (CT) scan
Rationale: The correct answer is Computed tomography (CT) scan. When screening for lung cancer, CT scans are recommended over chest X-rays due to their higher sensitivity in detecting lung nodules and early-stage cancers. Pulmonary function tests are not used for screening lung cancer but rather to assess lung function. Magnetic resonance imaging is not the preferred imaging modality for routine lung cancer screening, as CT scans are more commonly used.
2. Which of the following statements about chest X-rays is false?
- A. There are contraindications for this test
- B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
- C. A signed consent is not required
- D. Eating, drinking, and medications are allowed before this test
Correct answer: A
Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.
3. A nurse is assessing a client who is receiving enteral nutrition via a nasogastric tube. Which of the following findings should the nurse report to the provider?
- A. Gastric pH of 2.5.
- B. Bowel sounds every 4 hours.
- C. Diarrhea of 250 mL in 24 hours.
- D. Gastric residual of 150 mL.
Correct answer: D
Rationale: A gastric residual of 150 mL may indicate delayed gastric emptying and should be reported to the provider.
4. A patient is being treated for a severe fungal infection with amphotericin B. What is the expected length of treatment for this patient?
- A. 1 to 2 weeks
- B. 3 to 6 weeks
- C. 4 to 12 weeks
- D. 15 to 18 weeks
Correct answer: C
Rationale: The correct answer is C: '4 to 12 weeks.' Amphotericin B treatment duration for severe fungal infections typically ranges from 4 to 12 weeks. This extended period is necessary to ensure complete eradication of the fungal infection and prevent relapse. Choices A, B, and D provide durations that are either too short or too long for treating severe fungal infections effectively, making them incorrect.
5. A nurse is preparing to administer ampicillin 500 mg IV bolus every 6 hours. Available is ampicillin 500 mg in 50 mL dextrose 5% in water (D5W) to infuse over 20 minutes. The nurse should set the IV pump to deliver how many mL/hr?
- A. 100 mL/hr
- B. 150 mL/hr
- C. 200 mL/hr
- D. 250 mL/hr
Correct answer: B
Rationale: To infuse 50 mL over 20 minutes, the pump should be set to 150 mL/hr. This calculation ensures the correct rate for the infusion of the medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given information.
