The nurse is caring for a client with a history of atrial fibrillation who is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

A. Prothrombin time (PT)

B. Hemoglobin level

C. International Normalized Ratio (INR)

D. Serum sodium level

Correct Answer: C
Rationale: The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps determine if the client's blood is clotting appropriately. While prothrombin time (PT) is related to warfarin therapy, the INR is a more precise measure. Hemoglobin level and serum sodium level are not directly related to monitoring warfarin therapy.

When organizing home visits for the day, which older client should the home health nurse plan to visit first?

• A. A woman who takes naproxen (Naprosyn) and reports a recent onset of dark, tarry stools.
• B. A man who receives weekly injections of epoetin (Procrit) for a low serum iron level.
• C. A man with emphysema who smokes and is complaining of white patches in his mouth.
• D. A frail woman with heart failure who reported a 2-pound weight gain in the last week.

Correct Answer: A
Rationale: The correct answer is A. Dark, tarry stools may indicate gastrointestinal bleeding, a potentially life-threatening condition that requires immediate attention. Visiting this client first is crucial for prompt assessment and intervention. Choices B, C, and D do not present immediate life-threatening conditions that require urgent attention compared to the potential emergency indicated by dark, tarry stools.

A 10-year-old who has terminal brain cancer asks the nurse, 'What will happen to my body when I die?' How should the nurse respond?

• A. Your mother and father will be here soon. Talk to them about that.'
• B. Why do you want to know about what will happen to your body when you die?'
• C. The heart will stop beating and you will stop breathing.'
• D. Are you concerned about where your spirit will go?'

Correct Answer: C
Rationale: The correct response when a terminally ill child asks about what will happen to their body when they die is to provide a truthful and straightforward answer. Choice C, 'The heart will stop beating and you will stop breathing,' is the best response because it offers a simple and honest explanation without delving into spiritual or emotional aspects that may be confusing or distressing to the child. Choices A and D deflect the question and do not address the child's inquiry directly. Choice B, 'Why do you want to know about what will happen to your body when you die?' may come across as dismissive or evasive, rather than providing the clear information the child is seeking.

A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which assessment finding is most concerning?

• A. Increased fatigue
• B. Headache
• C. Elevated blood pressure
• D. Low urine output

Correct Answer: C
Rationale: In a client with chronic kidney disease receiving erythropoietin therapy, elevated blood pressure is the most concerning assessment finding. Erythropoietin can increase red blood cell production, leading to thicker blood, which in turn can elevate blood pressure. Elevated blood pressure in this scenario may indicate worsening hypertension, which requires prompt intervention to prevent complications such as stroke, heart attack, or further kidney damage. Increased fatigue (choice A) is a common symptom in CKD patients and can be expected with erythropoietin therapy. Headache (choice B) can occur but is less concerning than elevated blood pressure in this context. Low urine output (choice D) is a significant finding in CKD, but in a client receiving erythropoietin, elevated blood pressure takes precedence due to its potential for immediate adverse effects.

The nurse enters a client's room to administer scheduled daily medications and observes the client leaning forward and using pursed lip breathing. Which action is most important for the nurse to implement first?

• A. Evaluate the oxygen saturation.
• B. Administer a bronchodilator.
• C. Assist the client to sit upright.
• D. Encourage slow, deep breathing.

Correct Answer: A
Rationale: In this scenario, the nurse should first evaluate the oxygen saturation. This action is crucial as it provides immediate information on the client's respiratory status. Assessing the oxygen saturation can help determine the adequacy of oxygenation and guide further interventions. Administering a bronchodilator (Choice B) may be necessary based on assessment findings, but it should not be the first action without knowing the oxygen saturation level. While assisting the client to sit upright (Choice C) is generally beneficial for respiratory function, in this case, assessing oxygen saturation takes precedence. Encouraging slow, deep breathing (Choice D) can be helpful, but it is secondary to evaluating the oxygen saturation in this situation.
