1. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?
- A. 4,500/mm³
- B. 7,000/mm³
- C. 10,000/mm³
- D. 25,000/mm³
Correct answer: D
Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.
2. A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?
- A. Your urine can turn a dark orange.
- B. Watch for a change in the sclera of your eyes.
- C. Watch for any changes in vision.
- D. Take vitamin B6 daily.
Correct answer: C
Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.
3. Which of the following patients is at greater risk for contracting an infection?
- A. A patient with leukopenia
- B. A patient receiving broad-spectrum antibiotics
- C. A postoperative patient who has undergone orthopedic surgery
- D. A newly diagnosed diabetic patient
Correct answer: A
Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.
4. The physician orders 10 gr of aspirin for a patient. The equivalent dose in milligrams is:
- A. 0.6 mg
- B. 10 mg
- C. 60 mg
- D. 600 mg
Correct answer: D
Rationale: To convert grains (gr) to milligrams (mg), you multiply by 60. Therefore, 10 gr of aspirin is equal to 600 mg (10 gr x 60 = 600 mg). So, the correct answer is 600 mg.
5. A client experiencing acute dyspnea and diaphoresis reports anxiety and difficulty breathing. Vital signs include HR 117/min, respirations 38/min, temperature 38.4 C (101.2 F), and blood pressure 100/54 mm Hg. What should the nurse prioritize?
- A. Notify the provider.
- B. Administer heparin via IV infusion.
- C. Administer oxygen therapy.
- D. Obtain a spiral CT scan.
Correct answer: C
Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.
