Nursing Elites

1. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

2. The nurse is caring for a patient who has recently had a successful catheter ablation. Which assessment finding demonstrates a successful outcome of this procedure?

• A. The patient is free of electrolyte imbalances
• B. The patient's WBC count is within normal limits
• C. The patient's EKG reading is regular
• D. The patient's urine output is 45 mL/hour

Correct answer: C

Rationale: A successful outcome of a catheter ablation procedure for arrhythmias, particularly SVT, is indicated by a regular EKG reading. Catheter ablation involves the use of radiofrequency energy to destroy the conduction fiber in the heart responsible for the arrhythmia. This destruction helps in preventing further episodes of arrhythmia. While choices A, B, and D are important assessments in patient care, they are not specific indicators of the success of a catheter ablation procedure. Electrolyte imbalances, WBC count, and urine output can be affected by various factors and are not directly related to the effectiveness of a catheter ablation in treating arrhythmias.

3. When orally administering alendronate (Fosamax), a bisphosphonate drug, to a largely bed-bound patient being treated for osteoporosis, what is the most important nursing consideration?

• A. Sit the head of the bed up for 30 minutes after administration
• B. Give the patient a small amount of water to drink
• C. Feed the patient soon, at most 10 minutes after administration
• D. Assess the patient for back pain or abdominal pain

Correct answer: A

Rationale: The correct nursing consideration when administering bisphosphonates like alendronate is to sit the head of the bed up for 30 minutes after administration. Bisphosphonates are known to cause esophageal irritation, which can lead to esophagitis. By sitting upright, the patient reduces the time the medication spends in the esophagus, decreasing the risk of irritation and potential adverse effects. Giving the patient water to drink or feeding them immediately after administration can increase the risk of esophageal irritation. Assessing the patient for back pain or abdominal pain is important but not the most critical consideration during drug administration.

4. Which patient poses the least infection risk to an immunosuppressed patient who had a liver transplant?

• A. The patient with chronic pancreatitis
• B. The patient currently infected with a respiratory virus
• C. The patient with a healing leg wound
• D. The patient with a urinary tract infection

Correct answer: C

Rationale: The patient with a healing leg wound poses the least infection risk to an immunosuppressed patient who had a liver transplant. Chronic pancreatitis can lead to complications such as infections that can pose a risk to immunosuppressed individuals. Patients infected with respiratory viruses or urinary tract infections are actively infectious, which can put immunosuppressed patients at a higher risk of acquiring infections. Therefore, the patient with a healing leg wound is the least likely to pose an immediate infection risk.

5. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

• A. The life span of RBC is 45 days
• B. The life span of RBC is 60 days
• C. The life span of RBC is 90 days
• D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.
