The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Prothrombin time (PT)
- C. International Normalized Ratio (INR)
- D. Serum sodium level
Correct Answer: C
Rationale: The correct answer is C, 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 for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.

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 is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?
- A. Serum potassium
- B. Blood urea nitrogen (BUN)
- C. Serum creatinine
- D. Serum glucose
Correct Answer: C
Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.
An adult female client is admitted to the psychiatric unit with a diagnosis of major depressive disorder. The nurse notices the client has more energy and is giving her belongings away. Which intervention is best for the nurse to implement?
- A. Support the client by praising her progress.
- B. Ask the client if she has had any recent thoughts of harming herself.
- C. Reassure the client about the effectiveness of antidepressant drugs.
- D. Advise the client to keep her belongings for discharge.
Correct Answer: B
Rationale: The correct intervention is to ask the client if she has had any recent thoughts of harming herself because increased energy and giving away belongings can be signs of suicidal ideation. Choice A is incorrect as it does not address the potential risk of self-harm. Choice C is incorrect because reassurance about medication effectiveness may not be appropriate in this situation. Choice D is incorrect as it dismisses the client's current behavior without addressing the underlying concern of potential self-harm.
For the past 24 hours, an antidiarrheal agent, diphenoxylate, has been administered to a bedridden, older client with infectious gastroenteritis. Which finding requires the nurse to take further action?
- A. Tented skin turgor
- B. Decreased bowel sounds
- C. Persistent diarrhea
- D. Dehydration
Correct Answer: A
Rationale: The correct answer is A. Tented skin turgor is a sign of dehydration, which can be exacerbated by the use of antidiarrheals in clients with gastroenteritis. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. Therefore, the nurse should take immediate action upon noticing tented skin turgor to prevent further complications. Choices B, C, and D are incorrect because decreased bowel sounds, persistent diarrhea, and dehydration are expected findings in a client with gastroenteritis who has been administered an antidiarrheal agent.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning to the nurse?
- A. Barrel-shaped chest
- B. Use of accessory muscles
- C. Oxygen saturation of 85%
- D. Respiratory rate of 28 breaths per minute
Correct Answer: C
Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.
