Nursing Elites

1. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

2. A client is recovering from a closed percutaneous kidney biopsy and reports increased pain from 3 to 10 on a scale of 0 to 10. Which action should the nurse take first?

• A. Reposition the client on the operative side.
• B. Administer the prescribed opioid analgesic.
• C. Assess the pulse rate and blood pressure.
• D. Examine the color of the client’s urine.

Correct answer: C

Rationale: An abrupt increase in pain following a percutaneous kidney biopsy may indicate internal hemorrhage. Assessing the client's pulse rate and blood pressure is crucial as changes in vital signs can be indicative of hemorrhage. This assessment is essential in determining the client's hemodynamic status and the need for immediate intervention. Repositioning the client, administering pain medication, or checking urine color are not the priority actions in this situation and may delay necessary interventions for potential hemorrhage.

3. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.

4. A patient with a diagnosis of Cushing's syndrome is likely to exhibit which of the following symptoms?

• A. Hyperpigmentation.
• B. Moon face.
• C. Hypotension.
• D. Hypertension.

Correct answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

5. A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?

• A. Check the client’s digoxin (Lanoxin) level.
• B. Administer an anti-nausea medication.
• C. Ask if the client can eat crackers.
• D. Refer the client to a gastrointestinal specialist.

Correct answer: A

Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.
