Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is assessing a client who is receiving enteral nutrition via a nasogastric tube. Which of the following findings should the nurse report to the provider?

• A. Gastric pH of 2.5.
• B. Bowel sounds every 4 hours.
• C. Diarrhea of 250 mL in 24 hours.
• D. Gastric residual of 150 mL.

Correct answer: D

Rationale: A gastric residual of 150 mL may indicate delayed gastric emptying and should be reported to the provider.

3. A healthcare provider is assessing a client who has COPD and is receiving oxygen therapy at 2 L/min via nasal cannula. Which of the following findings should the provider report?

• A. Oxygen saturation of 95%.
• B. Productive cough with clear sputum.
• C. Respiratory rate of 22/min.
• D. Client reports dyspnea.

Correct answer: D

Rationale: The correct answer is D. Dyspnea in a client with COPD receiving oxygen should be reported as it may indicate worsening respiratory status. Oxygen saturation of 95% is within the expected range for a client receiving oxygen therapy and does not require immediate reporting. A productive cough with clear sputum is a common symptom in clients with COPD and does not necessarily warrant urgent reporting. A respiratory rate of 22/min is also within normal limits and does not raise immediate concerns in this scenario.

4. A nurse is planning care for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/minute
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate of 14 mL/minute indicates severe kidney dysfunction, necessitating hemodialysis. The other options, BUN of 16 mg/dL, serum magnesium of 1.8 mg/dL, and serum phosphorus of 4.0 mg/dL, are within normal ranges and do not serve as indications for hemodialysis.

5. A nurse is assessing a newborn's heart rate. Which of the following actions should the nurse take?

• A. Auscultate the apical pulse and count for 1 minute
• B. Place a sensor on the index finger
• C. Heat the skin prior to placing the probe
• D. Recheck after 10 minutes

Correct answer: A

Rationale: Corrected Rationale: Auscultating the apical pulse and counting for one minute is the appropriate method to accurately measure a newborn's heart rate. The apical pulse is located at the point of maximum impulse (PMI), which is usually at the fourth or fifth intercostal space along the mid-clavicular line. This method allows for a precise assessment of the newborn's heart rate. Choice B, placing a sensor on the index finger, is incorrect because this method is more suitable for measuring oxygen saturation rather than heart rate. Choice C, heating the skin prior to placing the probe, is unnecessary for assessing heart rate and may lead to potential burns in newborns. Choice D, rechecking after 10 minutes, is not appropriate as immediate assessment and intervention may be required if an abnormal heart rate is detected in a newborn.
