Nursing Elites

1. The nurse is assessing a client with pneumonia who is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client's respiratory rate is 20 breaths per minute.
• B. The client's arterial blood gases show a pH of 7.35.
• C. The client's oxygen saturation is 92%.
• D. The client's breath sounds are clear.

Correct answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client is able to expectorate secretions easily.
• B. The client's oxygen saturation is 92%.
• C. The client's respiratory rate is 20 breaths per minute.
• D. The client's arterial blood gases show a pH of 7.35.

Correct answer: C

Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.

3. The nurse is caring for a client with liver cirrhosis. Which assessment finding requires immediate intervention?

• A. Jaundice.
• B. Ascites.
• C. Peripheral edema.
• D. Spider angiomas.

Correct answer: D

Rationale: Spider angiomas are abnormal clusters of blood vessels near the skin surface and can be indicative of an underlying liver condition. In the context of liver cirrhosis, spider angiomas can suggest portal hypertension and liver dysfunction, which requires immediate intervention. Jaundice (choice A) is a common manifestation of liver cirrhosis but not typically an immediate intervention priority unless severe. Ascites (choice B) and peripheral edema (choice C) are also common in liver cirrhosis but do not require immediate intervention unless they are causing respiratory compromise or other urgent issues.

4. The client with liver cirrhosis needs immediate intervention for which abnormal laboratory result?

• A. Prothrombin time (PT) of 14 seconds.
• B. Bilirubin of 1.2 mg/dL.
• C. Albumin of 4 g/dL.
• D. Ammonia level of 80 mcg/dL.

Correct answer: D

Rationale: An elevated ammonia level of 80 mcg/dL indicates hepatic encephalopathy, a serious complication of liver cirrhosis that requires immediate intervention. Ammonia is a neurotoxin that accumulates in the blood due to impaired liver function, leading to cognitive impairment and altered mental status. Monitoring and lowering ammonia levels are crucial in managing hepatic encephalopathy to prevent further neurological deterioration. Prothrombin time, bilirubin, and albumin levels are important parameters in assessing liver function and overall health status in clients with liver cirrhosis, but an elevated ammonia level poses an immediate threat to neurological function and warrants prompt attention.

5. The healthcare provider is assessing the laboratory results for a client who is admitted with renal failure and osteodystrophy. Which findings are consistent with this client's clinical picture?

• A. Serum potassium of 4.0 mEq/L and total calcium of 9 mg/dL.
• B. White blood cell count of 15,000/mm3.
• C. Serum potassium of 5.5 mEq/L and total calcium of 6 mg/dL.
• D. Hemoglobin of 12 g/dL and phosphorus of 2 mg/dL.

Correct answer: C

Rationale: In renal failure and osteodystrophy, there is an alteration in serum electrolyte balance. The correct answer is serum potassium of 5.5 mEq/L and total calcium of 6 mg/dL. Renal failure is associated with hyperkalemia (elevated serum potassium) and hypocalcemia (low total calcium levels). Hyperphosphatemia is also commonly seen in renal failure. Choice A is incorrect as it describes normal levels of serum potassium and total calcium. Choice B is unrelated to the client's condition. Choice D is incorrect as it does not reflect the typical electrolyte imbalances seen in renal failure and osteodystrophy.
