Nursing Elites

1. A nurse is caring for a client who has a pulmonary embolism. The nurse should identify the effectiveness of the treatment by assessing which of the following?

• A. A chest x-ray reveals increased density in all lung fields
• B. The client reports feeling less anxious
• C. Diminished breath sounds are auscultated unilaterally
• D. ABG results include pH 7.48, PaO2 77 mm Hg, and PaCO2 47 mm Hg

Correct answer: B

Rationale: The correct answer is B. Client-reported improvement in anxiety is an indication of effective treatment for pulmonary embolism. Choice A is incorrect as increased density in all lung fields on a chest x-ray may indicate complications or lack of improvement. Choice C is incorrect as diminished breath sounds auscultated unilaterally may suggest a localized lung issue and not necessarily reflect the effectiveness of treatment for a pulmonary embolism. Choice D is incorrect as the ABG results provided do not specifically indicate the effectiveness of treatment for a pulmonary embolism.

2. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

3. A healthcare professional is reviewing the laboratory results of a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the professional report to the provider?

• A. Blood glucose level of 130 mg/dL
• B. Serum sodium level of 140 mEq/L
• C. Serum potassium level of 3.2 mEq/L
• D. Platelet count of 250,000/mm³

Correct answer: C

Rationale: A serum potassium level of 3.2 mEq/L indicates hypokalemia, a complication that should be reported in clients receiving TPN. Hypokalemia can lead to serious cardiac and neuromuscular complications. The other options are within normal ranges and do not indicate immediate concerns for a client receiving TPN. A blood glucose level of 130 mg/dL, serum sodium level of 140 mEq/L, and platelet count of 250,000/mm³ are all considered normal values and do not require immediate intervention.

4. A client is being assessed in the PACU. Which of the following findings indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

5. A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory values should the nurse monitor?

• A. Prothrombin time (PT)
• B. Hemoglobin
• C. aPTT
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.
