NCLEX RN Exam Review Answers
1. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?
- A. Induce vomiting
- B. Hold the next dose of Lithium
- C. Administer an antiemetic
- D. Give the next dose of Lithium
Correct answer: B
Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.
2. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?
- A. Administer hepatitis B vaccine.
- B. Test for antibodies to hepatitis B.
- C. Teach about alpha-interferon therapy.
- D. Give hepatitis B immune globulin.
Correct answer: C
Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.
3. A nurse is caring for a patient admitted to the emergency room for an ischemic stroke with marked functional deficits. The physician is considering the use of fibrinolytic therapy with TPA (tissue plasminogen activator). Which history-gathering question would not be important for the nurse to ask?
- A. What time did you first notice symptoms consistently appearing?
- B. Have you been taking any blood thinners such as heparin, lovenox, or warfarin?
- C. Have you had another stroke or head trauma in the previous 3 months?
- D. Have you had any blood transfusions within the previous year?
Correct answer: D
Rationale: The correct answer is 'Have you had any blood transfusions within the previous year?' This question is not relevant in the context of considering fibrinolytic therapy with TPA for an ischemic stroke. Blood transfusions within the previous year do not directly impact the decision to use TPA in the treatment of an acute ischemic stroke. The focus should be on factors such as the time of symptom onset, current medications like blood thinners, and recent history of strokes or head trauma, as these are more directly related to the decision-making process for administering TPA in this emergency situation.
4. A patient with Meningitis is being treated with Vancomycin intravenously 3 times per day. The nurse notes that the urine output during the last 8 hours was 200mL. What is the nurse's priority action?
- A. Check the patient's last BUN levels
- B. Ask the patient to increase their fluid intake
- C. Ask the physician to order a diuretic
- D. Notify the physician of this finding
Correct answer: D
Rationale: Vancomycin is a nephrotoxic drug and can cause impaired renal perfusion, which would lead to decreased urine output. This is a serious adverse effect that should be promptly reported to the physician. Checking the patient's last BUN levels (Choice A) may provide additional information but does not address the urgency of the situation. Asking the patient to increase fluid intake (Choice B) may not be appropriate if the cause is related to Vancomycin toxicity. Ordering a diuretic (Choice C) without physician evaluation can exacerbate the issue, making notifying the physician (Choice D) the most critical action to take.
5. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?
- A. A 20-year-old woman with unexplained joint pain and a low BMI.
- B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
- C. A 67-year-old man who had open-heart surgery 4 years ago.
- D. A 40-year-old woman in a hypomanic state for the last 2 days.
Correct answer: A
Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.
