Nursing Elites

1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

2. A 28-year-old woman presents with abdominal pain, diarrhea, and rectal bleeding. She has a history of similar episodes in the past. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Diverticulitis

Correct answer: A

Rationale: The constellation of symptoms including abdominal pain, diarrhea, and rectal bleeding in a young woman with a history of similar episodes is highly suggestive of ulcerative colitis. This chronic inflammatory condition primarily affects the colon and rectum, leading to symptoms such as bloody diarrhea, abdominal pain, and urgency. The recurrent nature of her symptoms and the presence of rectal bleeding further support this diagnosis over other conditions listed, such as irritable bowel syndrome, celiac disease, or diverticulitis, which typically do not present with the same combination of symptoms and history.

3. A client in acute renal failure has a serum potassium level of 6.3 mEq/L. What intervention can the nurse expect the healthcare provider to prescribe?

• A. Nitrofurantoin (Macrodantin) orally.
• B. Erythropoietin (Epogen) intravenously.
• C. Kayexalate retention enema.
• D. Azathioprine (Imuran) orally.

Correct answer: C

Rationale: In acute renal failure with high serum potassium levels, the healthcare provider is likely to prescribe a Kayexalate retention enema. Kayexalate is a medication used to lower elevated potassium levels by promoting potassium excretion through the gastrointestinal tract, thus aiding in the management of hyperkalemia in clients with renal failure.

4. A client who has Type 1 diabetes and is at 10-weeks gestation comes to the prenatal clinic complaining of a headache, nausea, sweating, feeling shaky, and being tired all the time. What action should the nurse take first?

• A. Check the blood glucose level.
• B. Draw blood for a Hemoglobin A1C.
• C. Assess urine for ketone levels.
• D. Provide the client with a protein snack.

Correct answer: A

Rationale: The correct action for the nurse to take first is to check the client's blood glucose level. This is crucial to determine if the symptoms are a result of hypoglycemia or hyperglycemia, which requires immediate attention to maintain the client's health and the health of the developing fetus.

5. In which situation is it most important for the registered nurse (RN) working on a medical unit to provide direct supervision?

• A. A graduate nurse needs to access a client's implanted port to start an infusion of Ringer's Lactate.
• B. A postpartum nurse pulled to the unit needs to start a transfusion of packed red blood cells.
• C. A practical nurse is preparing to assist the healthcare provider with a lumbar puncture at the bedside.
• D. An unlicensed assistive personnel is preparing to weigh an obese bedfast client using a bed scale.

Correct answer: A

Rationale: Direct supervision is essential when a complex task, such as accessing an implanted port, is being performed by a less experienced healthcare provider, in this case, a graduate nurse. This oversight ensures patient safety and proper execution of the procedure, especially when it is the nurse's first time performing such a task.
