1. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

2. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

3. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

4. Based on the signs and symptoms of erythema marginatum, Sydenham chorea, epistaxis, abdominal pain, fever, cardiac problems, and skin nodules in your 32-year-old female patient, what disorder would you most likely suspect?

• A. Leukemia
• B. Histoplasmosis
• C. Pneumocystis jiroveci
• D. Rheumatoid arthritis

Correct answer: D

Rationale: The signs and symptoms described point towards rheumatoid arthritis. Erythema marginatum, Sydenham chorea, epistaxis, abdominal pain, fever, cardiac issues, and skin nodules are classic manifestations of rheumatic fever, which is a complication of untreated streptococcal infection. This condition can lead to rheumatoid arthritis over time. Choices A, B, and C are incorrect as they do not align with the provided signs and symptoms, and they are not associated with the clinical presentation described.

5. A nurse enters a client room to witness an informed consent for a gastroscopy. The client states he does not understand the procedure. Which of the following actions should the nurse take?

• A. Educate the client about the risks of refusing medications
• B. Complete an incident report
• C. Answer the client's question concerning the procedure
• D. Inform the provider that the client requires clarification about the procedure

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to inform the provider that the client requires clarification about the procedure. This ensures that the client fully understands the gastroscopy procedure before giving consent. Choice A is incorrect as the client's issue is not about refusing medications. Choice B is irrelevant as there is no incident to report. Choice C could be misleading as the nurse should not be providing information about the procedure but rather ensuring that the client gets the necessary clarification from the provider.
