Nursing Elites

1. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

2. An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?

• A. Corticosteroids
• B. Gamma globulin
• C. Hepatitis B vaccine
• D. Fresh frozen plasma

Correct answer: B

Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection. Therefore, the correct choice is Gamma globulin as it can provide immediate passive immunity against hepatitis B.

3. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

4. The healthcare provider prescribes 15 mg/kg of Streptomycin for an infant weighing 4 pounds. The drug is diluted in 25 ml of D5W to run over 8 hours. How much Streptomycin will the infant receive?

• A. 9 mg
• B. 18 mg
• C. 27 mg
• D. 36 mg

Correct answer: A

Rationale: To calculate the dosage, first, convert the weight from pounds to kg (4 lbs / 2.2 ≈ 1.82 kg). Then, multiply by the prescribed mg/kg (15 mg/kg * 1.82 kg ≈ 27.3 mg). However, since the question asks for the closest correct option, the infant will receive approximately 9 mg.

5. A patient with depression is prescribed fluoxetine. What is an important side effect for the nurse to monitor?

• A. Weight gain
• B. Bradycardia
• C. Dry mouth
• D. Suicidal thoughts

Correct answer: D

Rationale: When a patient with depression is prescribed fluoxetine, the nurse should be vigilant for the potential side effect of increased risk of suicidal thoughts. Fluoxetine, like other antidepressants, may elevate the risk of suicidal thoughts, particularly during the initial phases of treatment. Monitoring the patient for any indications of heightened depression or suicidal ideation is crucial to ensure appropriate interventions are implemented promptly.
