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 patient with a pleural effusion is scheduled for a thoracentesis. Which action should the nurse take to prepare the patient for the procedure?
- A. Start a peripheral IV line to administer any necessary sedative drugs.
- B. Position the patient sitting upright on the edge of the bed and leaning forward.
- C. Obtain a collection device to hold a reasonable amount of pleural fluid for extraction.
- D. Remove the water pitcher and remind the patient not to eat or drink anything for 6 hours.
Correct answer: B
Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.
3. To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor
- A. bilirubin levels.
- B. ammonia levels.
- C. potassium levels.
- D. prothrombin time.
Correct answer: B
Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.
4. The healthcare provider is educating a parent about side effects of routine immunizations. Which of the following must be reported immediately?
- A. Irritability
- B. Slight edema at the injection site
- C. Local tenderness
- D. Temperature of 102.5?F
Correct answer: D
Rationale: A temperature of 102.5�F or higher following immunization is considered an adverse reaction and should be reported immediately. This could indicate a more serious systemic response to the vaccine. Irritability, slight edema at the injection site, and local tenderness are common, mild side effects of routine immunizations and do not typically require immediate reporting. Other reactions that should be reported immediately include excessive crying for more than 3 hours, seizure activity, and the presence of tender, swollen, or reddened areas at the injection site.
5. The nurse is caring for a 27-year-old female client with a venous stasis ulcer. Which nursing intervention would be most effective in promoting healing?
- A. Apply dressing using sterile technique
- B. Improve the client's nutrition status
- C. Initiate limb compression therapy
- D. Begin proteolytic debridement
Correct answer: B
Rationale: Venous stasis occurs when venous blood collects and stagnates in the lower leg due to incompetent venous valves. This leads to inadequate oxygen and nutrient supply to the cells in the lower extremities, resulting in cell death or necrosis. Venous stasis ulcers, characterized by shallow brown wounds with irregular margins, typically develop on the lower leg or ankle. The primary goal in managing clients with venous stasis ulcers is to promote healing. Proper nutrition plays a crucial role in wound healing. Nutritional deficiencies are common causes of venous ulcers, and a diet rich in protein, iron, zinc, and vitamins C and A is recommended to enhance wound healing. Applying dressings with sterile technique, initiating limb compression therapy, and beginning proteolytic debridement are important interventions in wound care but may not directly address the underlying issue of poor nutrition that is essential for healing venous stasis ulcers.
