Nursing Elites

1. The nurse is assessing a client with chronic heart failure who is receiving furosemide (Lasix). Which assessment finding is most concerning?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Elevated liver enzymes
• D. Elevated blood glucose level

Correct answer: C

Rationale: Elevated liver enzymes are most concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. Elevated liver enzymes can be a sign of hepatotoxicity or liver damage, which could be a result of furosemide (Lasix) use. Monitoring liver function is crucial in patients taking furosemide due to the risk of hepatotoxicity. A heart rate of 60 beats per minute and a blood pressure of 110/70 mmHg are within normal ranges for a client with chronic heart failure. An elevated blood glucose level may be expected due to the effects of furosemide but is not as immediately concerning as elevated liver enzymes.

2. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dL

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

3. The nurse is preparing to administer an enema to a client with severe constipation. Which position is most appropriate for the client?

• A. Supine with the head elevated 30 degrees
• B. Left lateral with the right leg flexed
• C. Sims’ position with the right leg flexed
• D. Prone position with the head turned to the side

Correct answer: C

Rationale: Sims’ position with the right leg flexed is the most appropriate position for administering an enema to a client with severe constipation. This position helps in promoting the flow of the enema solution into the rectum and facilitates the evacuation of stool. Supine position with the head elevated 30 degrees (Choice A) is not ideal for administering an enema as it does not facilitate the flow of the solution. Left lateral position with the right leg flexed (Choice B) is not the best choice for administering an enema. Prone position with the head turned to the side (Choice D) is also not suitable for administering an enema as it does not assist in the proper administration and retention of the solution.

4. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products while in the operating room. His current blood pressure is 78/52 mm Hg, he is being mechanically ventilated, and his oxygen saturation is 87%. His laboratory values include hemoglobin 7.0 g/dL, platelets 20,000/mm³, and white blood cells 1,500/mm³. Based on these assessment findings, which intervention should the nurse implement first?

• A. Transfuse packed red blood cells.
• B. Obtain blood and sputum cultures.
• C. Infuse 1000 ml of normal saline.
• D. Titrate oxygen to keep O2 saturation at 90%.

Correct answer: A

Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.

5. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.
