Nursing Elites

1. The client is admitted with chronic obstructive pulmonary disease. Blood gases reveal pH 7.36, CO2 45, O2 84, HCO3 28. The nurse would assess the client to be in:

• A. Uncompensated acidosis
• B. Compensated alkalosis
• C. Compensated respiratory acidosis
• D. Uncompensated metabolic acidosis

Correct answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

2. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

3. A client arrives in the emergency room with a possible fractured femur. The nurse should anticipate an order for:

• A. Trendelenburg position
• B. Ice to the entire extremity
• C. Buck's traction
• D. An abduction pillow

Correct answer: C

Rationale: The correct answer is Buck's traction. This intervention is used to realign the fractured femur, reduce spasms, and alleviate pain. Placing the client in the Trendelenburg position is inappropriate for a femur fracture, making answer A incorrect. While ice may be used post-repair, applying it to the entire extremity is unnecessary, so answer B is wrong. An abduction pillow is typically employed following a total hip replacement, not for a fractured femur, rendering answer D incorrect.

4. The nurse is caring for a client with laryngeal cancer. Which finding ascertained in the health history would not be common for this diagnosis?

• A. Foul breath
• B. Dysphagia
• C. Diarrhea
• D. Chronic hiccups

Correct answer: C

Rationale: Diarrhea is not a common finding in clients with laryngeal cancer. Foul breath (A), dysphagia (B), and chronic hiccups (D) are expected findings associated with laryngeal cancer. Foul breath can result from tissue breakdown in the mouth and throat. Dysphagia, or difficulty swallowing, can occur due to the tumor's location affecting the swallowing mechanism. Chronic hiccups can be a symptom of irritation to the phrenic nerves from the cancer.

5. While the client is receiving total parenteral nutrition (TPN), which lab test should be evaluated?

• A. Hemoglobin
• B. Creatinine
• C. Blood glucose
• D. White blood cell count

Correct answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.
