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. Round off these numbers to the nearest tenth:

• A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

3. 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.

4. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

• A. Proceed with treatment without obtaining written consent
• B. Contact the client's next of kin to obtain consent for treatment
• C. Have the client sign a consent for treatment
• D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

5. A nurse reviews a client's laboratory report and notes that the client's serum phosphorus level is 2.0 mg/dL. Which condition most likely caused this serum phosphorus level?

• A. Alcoholism
• B. Renal insufficiency
• C. Hypoparathyroidism
• D. Tumor lysis syndrome

Correct answer: A

Rationale: The correct answer is A: Alcoholism. Alcoholism can lead to hypophosphatemia due to poor dietary intake and other factors. Excessive alcohol consumption can result in malnutrition, particularly a deficiency in phosphorus. Choices B, C, and D are unlikely to cause low serum phosphorus levels. Renal insufficiency is more likely to cause hyperphosphatemia, hypoparathyroidism is associated with hypocalcemia rather than hypophosphatemia, and tumor lysis syndrome typically presents with hyperphosphatemia due to the release of intracellular phosphate.
