NCLEX-RN
NCLEX RN Predictor Exam
1. A urine pregnancy test:
- A. May be negative even if a blood pregnancy test is positive.
- B. Is positive only during the first trimester of pregnancy.
- C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
- D. All of the above.
Correct answer: A
Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.
2. What procedure examines a portion of the large intestine with an endoscope?
- A. Colposcopy
- B. Sigmoidoscopy
- C. Upper GI
- D. Cardiac catheterization
Correct answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.
3. A nurse is preparing to change a client's dressing for a burn wound on his foot. Which of the following interventions is appropriate for this process?
- A. Wash the wound with cleanser, rinse, and pat dry
- B. Bind the wound tightly, secure with tape, and elevate the foot
- C. Contact the physician after the dressing change is complete
- D. Provide analgesics for the client after the procedure
Correct answer: A
Rationale: When changing the dressing for a burn wound, it is essential to follow appropriate interventions to prevent infection, reduce pain, and support healing. In this scenario, after removing the old dressing, it is crucial to wash the wound gently with a suitable cleanser, rinse the area thoroughly, and then pat it dry. This process helps in maintaining cleanliness, reducing the risk of infection, and providing a conducive environment for healing. Binding the wound tightly (Choice B) can impede circulation and delay healing. Contacting the physician after the dressing change (Choice C) may be necessary in specific situations but is not a standard step in routine dressing changes. Providing analgesics after the procedure (Choice D) is important for pain management but is not directly related to the dressing change itself.
4. Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?
- A. Angina at rest
- B. Thrombus formation
- C. Dizziness
- D. Falling blood pressure
Correct answer: B
Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.
5. You are preparing to admit a patient with a seizure disorder. Which of the following actions can you delegate to an LPN/LVN?
- A. Complete admission assessment.
- B. Set up oxygen and suction equipment.
- C. Place a padded tongue blade at the bedside.
- D. Pad the side rails before the patient arrives.
Correct answer: B
Rationale: The correct answer is to delegate the task of setting up oxygen and suction equipment to the LPN/LVN. This task falls within their scope of practice and can be safely performed by them. Completing the admission assessment (Choice A) typically requires a higher level of assessment and critical thinking, making it more appropriate for a registered nurse. Placing a padded tongue blade at the bedside (Choice C) involves potential airway management, which is a more complex task and should be done by a higher-level provider. Padding the side rails before the patient arrives (Choice D) is a task related to patient safety and should be done by the healthcare team as a whole, not solely delegated to an LPN/LVN.
