Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?

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

Correct answer: B

Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.

3. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

4. When a client is suspected of having a stroke, what is the nurse's priority action?

• A. Administer tissue plasminogen activator (tPA).
• B. Perform a neurological assessment.
• C. Position the client in a supine position.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: The correct answer is to perform a neurological assessment. When a stroke is suspected, the priority action is to assess the client neurologically to determine the extent of brain injury and identify any immediate risks, such as impaired airway, speech deficits, or loss of motor function. This assessment helps in early recognition of signs that are essential for timely intervention and guides further treatment, such as administering tissue plasminogen activator (tPA), if appropriate. Positioning the client in a supine position or checking the blood glucose level can be important but not the priority when a stroke is suspected.

5. A client with peripheral vascular disease reports leg pain while walking. What intervention is most effective for the nurse to recommend?

• A. Recommend elevating the legs above the heart.
• B. Encourage the client to increase walking distance gradually.
• C. Encourage the client to avoid sitting or standing for long periods.
• D. Instruct the client to use warm compresses for pain relief.

Correct answer: B

Rationale: The correct answer is to encourage the client to increase walking distance gradually. This intervention is effective because gradual increases in walking distance promote circulation, improve oxygen delivery to tissues, and help reduce leg pain caused by peripheral vascular disease. Elevating the legs above the heart (Choice A) may be beneficial in other conditions like venous insufficiency but not specifically for peripheral vascular disease. Encouraging the client to avoid sitting or standing for long periods (Choice C) can help prevent blood pooling but does not directly address the walking-induced leg pain. Instructing the client to use warm compresses for pain relief (Choice D) may provide temporary relief but does not address the underlying circulation issues associated with peripheral vascular disease.
