NCLEX RN Practice Questions Exam Cram
1. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?
- A. Administer 30 Units of Lantus Daily
- B. CT of the spine with contrast
- C. X-ray of the abdomen and chest
- D. Administer heparin subcutaneously 5,000 Units every 12 hours
Correct answer: B
Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
2. A client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:
- A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
- B. The legs pulled toward the chest; the head bent back at a 30-degree angle
- C. The back arched; the arms and legs extended and rigid
- D. The legs extended and rotated externally; the head turned to the right or the left
Correct answer: A
Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.
3. Which interventions should the nurse include when creating a care plan for a child with hepatitis? Select one that doesn't apply.
- A. Providing a low-fat, well-balanced diet.
- B. Teaching the child effective hand-washing techniques.
- C. Notifying the primary health care provider (PHCP) if jaundice is present.
- D. Instructing the parents to avoid administering medications unless prescribed.
Correct answer: D
Rationale: The correct answer is instructing the parents to avoid administering medications unless prescribed. This choice is not directly related to the care of a child with hepatitis. It is essential for the nurse to educate the child and family about providing a low-fat, well-balanced diet to support the liver, teaching effective hand-washing techniques to prevent the spread of infection, and notifying the primary health care provider if jaundice is present to monitor the progression of the disease and adjust the treatment plan accordingly. Avoiding unnecessary medications is crucial, but it should be done under healthcare provider guidance, so the statement should be revised to reflect this aspect. Therefore, the other options are appropriate for the care of a child with hepatitis.
4. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?
- A. Intercostal retractions
- B. Kussmaul respirations
- C. Low oxygen saturation (SpO2)
- D. Decreased venous O2 pressure
Correct answer: B
Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.
5. The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?
- A. Neurotoxicity
- B. Hepatomegaly
- C. Nephrotoxicity
- D. Ototoxicity
Correct answer: C
Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.
