NCLEX RN Practice Questions Exam Cram
1. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?
- A. Administer 30 Units of Lantus Daily
- B. CT of the spine with contrast
- C. X-ray of the abdomen and chest
- D. Administer heparin subcutaneously 5,000 Units every 12 hours
Correct answer: B
Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
2. A patient in the emergency room has a fractured left elbow and presents with an unequal radial pulse, swelling, and numbness in the left hand after waiting for 5 hours. What is the nurse's priority intervention?
- A. Place the patient in a supine position
- B. Ask the patient to rate his pain on a scale of 1 to 10.
- C. Wrap the fractured area with a snug dressing
- D. Start an IV in the other arm.
Correct answer: D
Rationale: The correct answer is to start an IV in the other arm. In this scenario, the patient is showing signs of Acute Compartment Syndrome, a serious condition that occurs due to increased pressure within a muscle compartment, leading to decreased blood flow and potential tissue damage. Starting an IV is crucial as the patient may require emergency surgery, such as a fasciotomy, to relieve the pressure and prevent further complications. Placing the patient in a supine position, asking about pain levels, or wrapping the fractured area, though important, are not the priority interventions in this critical situation where immediate medical intervention is necessary to prevent irreversible damage or loss of limb.
3. A patient underwent fiberoptic colonoscopy 18 hours ago and presents to the emergency department with increasing abdominal pain, fever, and chills. Which of the following conditions poses the most immediate concern?
- A. Bowel perforation
- B. Viral gastroenteritis
- C. Colon cancer
- D. Diverticulitis
Correct answer: A
Rationale: The correct answer is bowel perforation. Bowel perforation is the most serious complication of fiberoptic colonoscopy, with signs such as progressive abdominal pain, fever, chills, and tachycardia indicating advancing peritonitis. Although colonoscopic perforation is rare (0.03% to 0.7% incidence), it can lead to high mortality and morbidity rates. Viral gastroenteritis (Choice B) typically presents with symptoms like diarrhea, nausea, vomiting, and abdominal cramps, but it is not the most immediate concern in this scenario. Colon cancer (Choice C) and diverticulitis (Choice D) are important conditions but are less likely to present acutely after colonoscopy compared to bowel perforation.
4. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?
- A. Is there any family history of TB?
- B. How long have you lived in the United States?
- C. Do you take any over-the-counter (OTC) medications?
- D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?
Correct answer: D
Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.
5. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?
- A. The life span of RBC is 45 days
- B. The life span of RBC is 60 days
- C. The life span of RBC is 90 days
- D. The life span of RBC is 120 days
Correct answer: D
Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.
