Nursing Elites

1. A client admitted to the hospital with a diagnosis of acute pancreatitis has blood drawn for several serum laboratory tests. Which of the following serum amylase values, noted by the nurse reviewing the results, would be expected in this client at this time?

• A. 48 units/L
• B. 97 units/L
• C. 150 units/L
• D. 395 units/L

Correct answer: D

Rationale: The correct answer is D: "395 units/L." The normal serum amylase range is 25 to 151 units/L. In acute pancreatitis, the amylase level is greatly increased, typically exceeding the upper limit of the normal range. Choices A, B, and C fall within the normal range of serum amylase levels and would not be expected in a client with acute pancreatitis.

2. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?

• A. Iso-osmolar
• B. Hypo-osmolar
• C. Hyperosmolar
• D. Isotonic

Correct answer: C

Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.

3. The nurse notes that the only ECG for a 55-year-old male client scheduled for surgery in two hours is dated two years ago. The client reports that he has a history of 'heart trouble,' but has no problems at present. Hospital protocol requires that those over 50 years of age have a recent ECG prior to surgery. What nursing action is best for the nurse to implement?

• A. Ask the client to explain what he means by 'heart trouble.'
• B. Call for an ECG to be performed immediately.
• C. Notify surgery that the ECG is over two years old.
• D. Notify the client's surgeon immediately.

Correct answer: B

Rationale: In this scenario, the client is 55 years old with a history of 'heart trouble,' which necessitates a recent ECG before surgery as per hospital policy. The nurse should prioritize patient safety and adhere to the protocol by arranging for an ECG to be performed immediately. Option A is not the best initial action as the focus should be on obtaining the necessary test first. Option C is not the immediate action required, and option D is premature without obtaining the necessary ECG first.

4. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Decreased pain.
• D. Increased blood viscosity.

Correct answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

5. The nurse is caring for a patient who has recurrent urinary tract infections. The patient’s current infection is not responding to an antibiotic that has been used successfully several times in the past. The nurse understands that this is most likely due to

• A. acquired bacterial resistance.
• B. cross-resistance.
• C. inherent bacterial resistance.
• D. transferred resistance.

Correct answer: A

Rationale: The correct answer is A: acquired bacterial resistance. Acquired resistance happens when an organism has been exposed to the antibacterial drug, making it less effective over time. Cross-resistance (B) occurs when resistance to one drug leads to resistance to another. Inherent resistance (C) happens without prior exposure to the drug, meaning the bacteria are naturally resistant. Transferred resistance (D) involves the transfer of resistant genes from one organism to another, contributing to resistance development.
