Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?

• A. An 8-year-old living in a housing project.
• B. A 2-year-old playing on aging playground equipment.
• C. An adolescent working in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.

3. The healthcare provider is performing a physical assessment on a client who just had an endotracheal tube inserted. Which finding would call for immediate action by the healthcare provider?

• A. Breath sounds are audible bilaterally
• B. Mist is visible in the T-piece
• C. Pulse oximetry of 88
• D. Client is unable to verbalize

Correct answer: C

Rationale: A pulse oximetry reading of 88 indicates hypoxia, which is a serious condition requiring immediate intervention. Adequate oxygenation is crucial for the client's well-being. Choices A and B are normal findings after endotracheal intubation. Hearing bilateral breath sounds and seeing mist in the T-piece indicate proper functioning of the endotracheal tube. While choice D may indicate an issue with speaking due to the endotracheal tube, it is not as critical as the hypoxia indicated by the low pulse oximetry reading.

4. A male client with heart failure presents with shortness of breath, audible wheezing, and pink frothy sputum. What action should the nurse take?

• A. Consult with the charge nurse regarding morphine prescription.
• B. Administer the dose of morphine sulfate as prescribed.
• C. Withhold morphine until dyspnea resolves.
• D. Review the need for the prescription with the healthcare provider.

Correct answer: B

Rationale: The correct answer is B: Administer the dose of morphine sulfate as prescribed. In heart failure, morphine helps reduce anxiety, preload, and afterload on the heart, improving oxygenation. The client's symptoms indicate acute decompensated heart failure, and morphine should be administered promptly to relieve distress. Consulting the charge nurse (Choice A) or withholding morphine (Choice C) would delay necessary treatment. Reviewing the prescription with the healthcare provider (Choice D) is not needed in this acute situation.

5. 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.
