Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. During the physical assessment, which finding should the nurse recognize as a normal finding?

• A. Regular pulsation at the epigastric area when the client is supine.
• B. A loud, harsh murmur at the second right intercostal space.
• C. Dullness over the lung fields.
• D. Increased tactile fremitus.

Correct answer: A

Rationale: The regular pulsation at the epigastric area when the client is supine is a normal finding. This phenomenon is caused by the regular and recurrent expansion and contraction of an artery due to waves of pressure caused by the ejection of blood from the left ventricle. Choices B, C, and D describe abnormal findings during a physical assessment. A loud, harsh murmur at the second right intercostal space indicates an abnormal heart sound, dullness over the lung fields may suggest consolidation or fluid in the lungs, and increased tactile fremitus can be a sign of lung consolidation or pathology.

3. During a repeat home visit to see an 84-year-old widow, the nurse discovers that the client is unkempt, smells of stale urine, and does not recognize her neighbors or the nurse. What action should the nurse take?

• A. Call the pharmacy to determine what medications she is taking
• B. Seek the family's assistance in taking care of the client
• C. Complete a physical and mental exam on the client
• D. Call the adult protective services to obtain emergency nursing home placement

Correct answer: C

Rationale: In this scenario, the nurse should prioritize completing a physical and mental exam on the client. This action is crucial to assess the client's health status comprehensively and identify any underlying issues contributing to her unkempt appearance, odor of stale urine, and confusion. Calling the pharmacy to determine medications (Choice A) may be important but is not the immediate priority. Seeking family assistance (Choice B) can be helpful, but the client's condition requires a thorough assessment first. While adult protective services (Choice D) may be necessary in the future, the immediate action should be to assess the client's physical and mental health status.

4. The nurse is teaching a group of new mothers about infant care. Which topic should the nurse prioritize?

• A. signs of infant dehydration
• B. proper diaper changing techniques
• C. immunization schedule
• D. breastfeeding positions

Correct answer: A

Rationale: The correct answer is A: signs of infant dehydration. Recognizing signs of dehydration is crucial for ensuring the health and well-being of infants. Dehydration can be life-threatening for infants if not addressed promptly. While proper diaper changing techniques, immunization schedules, and breastfeeding positions are also important topics in infant care, being able to identify signs of dehydration takes precedence as it requires immediate attention to prevent serious consequences.

5. The healthcare provider is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which intervention is most important?

• A. Restrict fluids to 1,000 mL per day.
• B. Administer a vasopressin antagonist.
• C. Monitor intake and output.
• D. Encourage a high-sodium diet.

Correct answer: B

Rationale: Administering a vasopressin antagonist is the most critical intervention for a client with SIADH. SIADH is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. A vasopressin antagonist helps manage the symptoms by blocking the effects of ADH, promoting water excretion, and restoring electrolyte balance. Restricting fluids (choice A) may exacerbate hyponatremia, monitoring intake and output (choice C) is important but not the most critical intervention, and encouraging a high-sodium diet (choice D) is contraindicated in SIADH due to the risk of worsening hyponatremia.
