Nursing Elites

1. A client presents with a urine specific gravity of 1.018. What action should the nurse take?

• A. Evaluate the client’s intake and output for the past 24 hours.
• B. Document the finding in the chart and continue to monitor.
• C. Obtain a specimen for a urine culture and sensitivity.
• D. Encourage the client to drink more fluids, especially water.

Correct answer: B

Rationale: A urine specific gravity of 1.018 falls within the normal range, indicating adequate hydration. Therefore, the appropriate action is to document this finding in the client's chart and continue monitoring. There is no need to evaluate intake and output, as the specific gravity is normal. Obtaining a urine culture and sensitivity or encouraging increased fluid intake is unnecessary in this situation.

2. A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client's admitting diagnosis?

• A. An enlarged, distended abdomen.
• B. Crackles in the bases of both lungs.
• C. Jugular vein distension.
• D. Peripheral edema.

Correct answer: B

Rationale: The correct answer is B. Crackles in the bases of the lungs are indicative of fluid accumulation, which is common in left-sided heart failure. In left-sided heart failure, the heart is unable to effectively pump blood from the lungs to the rest of the body, leading to a backup of fluid in the lungs. This results in crackles heard on auscultation. Choices A, C, and D are not specific to left-sided heart failure. An enlarged, distended abdomen may indicate ascites or liver congestion. Jugular vein distension is more commonly associated with right-sided heart failure, and peripheral edema is a sign of fluid accumulation in the tissues, which can occur in both types of heart failure but is not as specific to left-sided heart failure as crackles in the lungs.

3. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.

4. A client with diabetes mellitus is scheduled to have blood drawn for a fasting blood glucose determination in the morning. What does the nurse tell the client is acceptable to consume on the morning of the test?

• A. Water
• B. Tea without sugar
• C. Coffee without milk
• D. Clear liquids like apple juice

Correct answer: A

Rationale: The correct answer is A: Water. A client scheduled for a fasting blood glucose test should only consume water after midnight to ensure accurate test results. Choosing options B, C, or D, which include tea, coffee, or clear liquids like apple juice, is incorrect as they may contain substances that can affect the blood glucose levels, leading to inaccurate test results.

5. 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.
