NCLEX RN Exam Review Answers
1. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?
- A. Heparin will dissolve clots that you have.
- B. Heparin will reduce the platelets that make your blood clot.
- C. Heparin will work better than warfarin.
- D. Heparin will prevent new clots from developing.
Correct answer: D
Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
2. A client presents with symptoms of a sore throat, swollen lymph nodes in the neck, fever, chills, and extreme fatigue. Based on these symptoms, which of the following illnesses could the nurse consider for this client?
- A. Methicillin-resistant Staphylococcus aureus (MRSA)
- B. Hepatitis B
- C. Infectious mononucleosis
- D. Norovirus infection
Correct answer: C
Rationale: Infectious mononucleosis is a viral disease caused by the Epstein-Barr virus. The symptoms of sore throat, fever, chills, swollen lymph nodes, and extreme fatigue are characteristic of infectious mononucleosis. The diagnosis is confirmed through the client's history and blood tests for the Epstein-Barr virus. Methicillin-resistant Staphylococcus aureus (MRSA) presents with localized skin infections, not the systemic symptoms described. Hepatitis B typically presents with jaundice, abdominal pain, and liver inflammation, not the symptoms described. Norovirus infection commonly causes gastrointestinal symptoms like vomiting and diarrhea, not the symptoms presented by the client.
3. After surgery for an imperforate anus, an infant returns with a red and edematous colostomy stoma. What action should the nurse take based on this finding?
- A. Elevate the buttocks.
- B. Document the findings.
- C. Apply ice immediately.
- D. Call the primary health care provider.
Correct answer: B
Rationale: A red and edematous colostomy stoma is a common finding immediately after surgery, and these changes are expected to decrease over time. As the stoma heals, it usually becomes pink without signs of abnormal drainage, swelling, or skin breakdown. Therefore, the appropriate action for the nurse is to document these normal findings. Elevating the buttocks, applying ice, or calling the primary health care provider are unnecessary interventions at this stage.
4. 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.
5. The nurse provides preoperative instruction for a patient scheduled for a left pneumonectomy for lung cancer. Which information should the nurse include about the patient's postoperative care?
- A. Positioning on the right side
- B. Bed rest for the first 24 hours
- C. Frequent use of an incentive spirometer
- D. Chest tube placement with continuous drainage
Correct answer: C
Rationale: After a pneumonectomy, frequent deep breathing and coughing are essential to prevent atelectasis and promote gas exchange. Patients are typically positioned on the surgical side to aid in gas exchange. Early mobilization is crucial to reduce the risk of postoperative complications such as pneumonia and deep vein thrombosis. While chest tubes may or may not be placed in the surgical space, if used, they are clamped and only adjusted by the surgeon to manage serosanguineous fluid accumulation. Overfilling of the chest cavity can compromise remaining lung function and cardiovascular status. Chest x-rays are useful for monitoring fluid volume and space postoperatively. Therefore, the correct postoperative care instruction for the patient undergoing a left pneumonectomy is the frequent use of an incentive spirometer. Choices A, B, and D are incorrect as positioning on the right side, bed rest for the first 24 hours, and continuous chest tube drainage are not standard postoperative care practices for patients undergoing pneumonectomy.
