Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Prothrombin time (PT)
• C. Serum sodium level
• D. Hemoglobin level of 12 g/dl

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

2. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. The infant was born two weeks after his due date and is described as a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

• A. Has your son had any immunizations yet?
• B. Is your son sleepy and difficult to feed?
• C. Are you breastfeeding or bottle-feeding your son?
• D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.

3. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Blood glucose level

Correct answer: A

Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.

4. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

5. When administering ceftriaxone sodium (Rocephin) intravenously to a client, what finding requires the most immediate intervention by the nurse?

• A. Stridor
• B. Nausea
• C. Headache
• D. Pruritus

Correct answer: A

Rationale: The correct answer is A: Stridor. Stridor is a high-pitched sound that indicates airway obstruction. When administering ceftriaxone sodium (Rocephin) intravenously, if the client develops stridor, it is a medical emergency requiring immediate intervention to maintain a patent airway. Nausea, headache, and pruritus are important to assess, but they do not pose an immediate threat to the client's airway and would not require the same level of urgent intervention as stridor.
