Nursing Elites

1. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

2. A client with cirrhosis is admitted with hepatic encephalopathy. Which clinical finding is most concerning?

• A. Confusion and altered mental status
• B. Increased abdominal girth
• C. Yellowing of the skin
• D. Peripheral edema

Correct answer: A

Rationale: Confusion and altered mental status are the most concerning clinical findings in a client with hepatic encephalopathy. These symptoms indicate worsening liver function and potential neurological complications, requiring immediate medical attention. Increased abdominal girth may suggest ascites, yellowing of the skin can indicate jaundice, and peripheral edema may be related to fluid retention, but in the context of hepatic encephalopathy, confusion and altered mental status take precedence due to the risk of rapid deterioration and the need for prompt management.

3. The nurse is caring for a client with a history of myocardial infarction who is complaining of chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Administer nitroglycerin sublingually as prescribed.
• C. Obtain an electrocardiogram (ECG).
• D. Assess the client's level of consciousness.

Correct answer: C

Rationale: Obtaining an electrocardiogram (ECG) is the first priority in assessing for ischemia or infarction in a client with chest pain and a history of myocardial infarction. This diagnostic test provides crucial information about the heart's electrical activity and helps in identifying any acute cardiac changes. Administering oxygen therapy and nitroglycerin can be important interventions, but obtaining an ECG takes precedence as it directly assesses the client's cardiac status. Assessing the client's level of consciousness is also essential, but in this scenario, assessing for cardiac indications through an ECG is the initial step.

4. A client with liver cirrhosis and severe ascites has a serum sodium level of 115 mEq/L and is receiving 3% saline IV. Which assessment finding indicates that the nurse should notify the healthcare provider?

• A. The client's serum sodium level is now 130 mEq/L
• B. The client reports a headache and has a BP of 140/90
• C. The client reports shortness of breath and has an O2 saturation of 92%
• D. The client has crackles in both lung bases and an increased respiratory rate.

Correct answer: D

Rationale: The presence of crackles in both lung bases and an increased respiratory rate indicates fluid overload, which can be exacerbated by hypertonic saline. This condition can worsen the client's respiratory status and lead to further complications. The other options do not directly relate to the fluid overload caused by the hypertonic saline. A serum sodium level of 130 mEq/L is within a normal range for treatment. A headache and a blood pressure of 140/90 are not specific indicators of worsening condition related to hypertonic saline. Shortness of breath and an O2 saturation of 92% could be related to other factors in a client with liver cirrhosis and ascites.

5. A female client reports that she drank a liter of a solution to cleanse her intestines but vomited immediately after. How many ml of fluid intake should the nurse document?

• A. 1000 ml
• B. 800 ml
• C. 760 ml
• D. 500 ml

Correct answer: C

Rationale: The correct answer is 760 ml. One liter equals 1000 ml. As the client vomited immediately after drinking, she would have expelled approximately 240 ml (1 cup). Subtracting this from the initial intake of 1000 ml gives us 760 ml as the remaining fluid intake that should be documented. Choices A, B, and D are incorrect because they do not reflect the correct calculation of subtracting the amount vomited from the initial intake.
