Nursing Elites

1. Which statement best describes electrolytes in intracellular and extracellular fluid?

• A. There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid
• B. There is an equal concentration of sodium and potassium in extracellular fluid
• C. There is a greater concentration of potassium in extracellular fluid and sodium in intracellular fluid
• D. There is an equal concentration of sodium and potassium between intracellular and extracellular fluid

Correct answer: A

Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.

2. When administering intravenous electrolyte solution, what precaution should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for adjustments due to IV calcium.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer. Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects. Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia. Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.

3. A client is admitted for observation following an unrestrained motor vehicle accident. A bystander stated that he lost consciousness for 1-2 minutes. On admission, the client's Glasgow Coma Scale (GCS) was 14. The GCS is now 12. The nurse should:

• A. Re-assess in 15 minutes
• B. Stimulate the client with a sternal rub
• C. Administer Tylenol with codeine for a headache
• D. Notify the physician

Correct answer: D

Rationale: A decrease in the Glasgow Coma Scale (GCS) score from 14 to 12 indicates a significant neurological change in the client's condition. This change can be indicative of a deterioration in the client's neurological status, possibly due to intracranial bleeding or swelling. It is crucial for the nurse to notify the physician immediately to ensure prompt evaluation and intervention. Re-assessing in 15 minutes or stimulating the client with a sternal rub are not appropriate actions in this situation as they do not address the underlying cause of the decrease in GCS. Administering Tylenol with codeine for a headache is also not recommended without further assessment and evaluation of the client's condition.

4. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: D

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.

5. The nurse is obtaining a health assessment from the preoperative client scheduled for hip replacement surgery. Which statement by the client would be most important for the nurse to report to the physician?

• A. "I had chickenpox when I was 8 years old."?
• B. "I had rheumatic fever when I was 10 years old."?
• C. "I have a strong family history of gastric cancer."?
• D. "I have pain in my hip with any movement."?

Correct answer: B

Rationale: The most important statement for the nurse to report to the physician is that the client had rheumatic fever when they were 10 years old. This information is crucial as individuals who have had rheumatic fever require pre-medication with antibiotics before any surgical or dental procedure to prevent bacterial endocarditis. Reporting this history ensures the client's safety during the hip replacement surgery. The other options, such as having chickenpox in the past, a family history of gastric cancer, or experiencing hip pain, are important for the client's overall health assessment but do not have the same immediate implications for the upcoming surgery as the history of rheumatic fever.
