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. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?
- A. Behavior
- B. Cognition
- C. Affect and mood
- D. Perceptual disturbances
Correct answer: B
Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.
3. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
- A. HCV
- B. HPV
- C. HIV
- D. HBV
Correct answer: A
Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
4. A newly admitted patient with major depression has lost 20 pounds over the past month and has suicidal ideation. The patient has taken an antidepressant medication for 1 week without remission of symptoms. Select the priority nursing diagnosis.
- A. Imbalanced nutrition: Less than body requirements
- B. Chronic low self-esteem
- C. Risk for suicide
- D. Hopelessness
Correct answer: B
Rationale: The priority nursing diagnosis in this scenario is 'Risk for suicide.' When a patient presents with major depression, significant weight loss, suicidal ideation, and lack of symptom improvement despite medication, the immediate concern is to address the risk of suicide. 'Risk for suicide' takes precedence as it involves a direct threat to the patient's life. 'Imbalanced nutrition: Less than body requirements' may be a concern but does not take priority over the risk of suicide. 'Chronic low self-esteem' and 'Hopelessness' are relevant issues in depression but are not as urgent as addressing the immediate risk of suicidal behavior.
5. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?
- A. PT/INR
- B. CBC
- C. PTT
- D. WBC
Correct answer: A
Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
