1. Which lab value is critical for patients on warfarin therapy?
- A. Monitor INR
- B. Monitor potassium levels
- C. Monitor sodium levels
- D. Monitor platelet count
Correct answer: A
Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.
2. A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?
- A. Weak femoral pulses.
- B. Frequent nosebleeds.
- C. Upper extremity hypotension.
- D. Increased intracranial pressure.
Correct answer: A
Rationale: Corrected Rationale: Weak femoral pulses are an expected finding in an infant with coarctation of the aorta. The narrowing of the aorta leads to decreased blood flow to the lower extremities, resulting in weak or absent femoral pulses. Frequent nosebleeds (Choice B) are not typically associated with coarctation of the aorta. Upper extremity hypotension (Choice C) is not a common finding in coarctation of the aorta; instead, blood pressure is usually elevated in the upper extremities. Increased intracranial pressure (Choice D) is not directly related to coarctation of the aorta.
3. A nurse is reviewing the laboratory results of a client who has systemic lupus erythematosus (SLE). Which of the following findings should the nurse report to the provider?
- A. White blood cell count 6,000/mm3
- B. Positive antinuclear antibody (ANA) titer
- C. Platelet count 220,000/mm3
- D. Blood urea nitrogen (BUN) 15 mg/dL
Correct answer: B
Rationale: A positive antinuclear antibody (ANA) titer is a significant finding in clients with systemic lupus erythematosus (SLE) as it indicates active disease. This result should be reported to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and not specifically indicative of disease activity in SLE. Therefore, they do not require immediate reporting to the provider.
4. A healthcare provider is teaching a client who has a new prescription for levothyroxine. Which of the following instructions should the healthcare provider include?
- A. Take this medication with meals.
- B. Take this medication at the same time every day.
- C. Report any chest pain to your healthcare provider immediately.
- D. Take an antacid if indigestion occurs.
Correct answer: B
Rationale: The correct instruction for a client prescribed levothyroxine is to take the medication at the same time every day. This consistency is important for maintaining stable thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach to ensure proper absorption. Choice C is important but not directly related to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.
5. A client who has a new prescription for warfarin is being taught about the medication's adverse effects by a nurse. Which of the following client statements indicates an understanding of the teaching?
- A. ''I should expect mild bruising around my elbows.''
- B. ''I should report a red rash to my provider.''
- C. ''I should stop taking this medication if I develop a cough.''
- D. ''I should expect black, tarry stools.''
Correct answer: D
Rationale: The correct answer is D. Black, tarry stools can indicate gastrointestinal bleeding, a serious adverse effect of warfarin that requires immediate medical attention. Option A is incorrect because while bruising is a common side effect of warfarin, it is not limited to the elbows. Option B is incorrect as a red rash is not a typical adverse effect of warfarin. Option C is also incorrect because developing a cough is not a reason to discontinue warfarin unless advised by a healthcare provider.
