Nursing Elites

1. When teaching a client postoperative breathing techniques with an incentive spirometer (IS), what should the nurse encourage the client to do to maintain sustained maximal inspiration?

• A. Exhale forcefully into the tubing for 3 to 5 seconds.
• B. Inspire deeply and slowly over 3 to 5 seconds.
• C. Breathe into the spirometer using normal breath volumes.
• D. Perform IS breathing exercises every 6 hours.

Correct answer: B

Rationale: To maintain sustained maximal inspiration when using an incentive spirometer, the client should be encouraged to inspire deeply and slowly over 3 to 5 seconds. This technique aids in achieving the goal of sustained maximal inspiration, which is essential for postoperative respiratory recovery.

2. In a patient with chronic kidney disease (CKD) receiving erythropoietin therapy, what laboratory result should the nurse monitor to evaluate the effectiveness of this therapy?

• A. Serum creatinine
• B. White blood cell count
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.

3. A patient with type 1 diabetes is prescribed insulin glargine. What is the primary characteristic of this insulin?

• A. Rapid-acting
• B. Intermediate-acting
• C. Long-acting
• D. Short-acting

Correct answer: C

Rationale: Insulin glargine is classified as a long-acting insulin. It is designed to provide a consistent level of insulin over approximately 24 hours, helping to keep blood glucose levels stable throughout the day. This long duration of action makes it suitable for basal insulin replacement in patients with type 1 diabetes, providing a background level of insulin to mimic the body's natural release of insulin between meals and overnight.

4. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?

• A. Hepatic encephalopathy
• B. Hypoglycemia
• C. Electrolyte imbalance
• D. Dehydration

Correct answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.

5. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.
