NCLEX RN Exam Review Answers
1. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?
- A. Diarrhea and Vomiting
- B. Dizziness and Drowsiness
- C. Metallic taste
- D. Hypoglycemia
Correct answer: Hypoglycemia
Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.
2. 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: Have you had any blood transfusions within the previous year?
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.
3. During a physical exam, a healthcare professional assisting a client suspected of having meningitis bends the client's leg at the hip to a 90-degree angle. When attempting to extend the leg at the knee, the client experiences severe pain. What type of test is being performed?
- A. Brudzinski's sign
- B. Romberg's sign
- C. Kernig's sign
- D. Babinski's sign
Correct answer: Kernig's sign
Rationale: The healthcare professional is performing Kernig's sign, a test for meningeal irritation often seen in meningitis cases. Kernig's sign involves bending the client's leg at a 90-degree angle at the hip and then attempting to extend the leg at the knee. Severe pain during this maneuver indicates a positive Kernig's sign, suggesting irritation of the meningeal membranes. Brudzinski's sign involves flexing the neck causing involuntary flexion of the hips and knees; Romberg's sign assesses balance and proprioception; Babinski's sign checks for abnormal reflexes in the foot.
4. Which client is at highest risk for developing a pressure ulcer?
- A. 23 year-old in traction for fractured femur
- B. 72 year-old with peripheral vascular disease, who is unable to walk without assistance
- C. 75 year-old with left sided paresthesia and is incontinent of urine and stool
- D. 30 year-old who is comatose following a ruptured aneurysm
Correct answer: 75 year-old with left sided paresthesia and is incontinent of urine and stool
Rationale: Risk factors for pressure ulcers include: immobility, absence of sensation, decreased LOC, poor nutrition and hydration, skin moisture, incontinence, increased age, decreased immune response. This client has the greatest number of risk factors.
5. An older patient is receiving standard multidrug therapy for tuberculosis (TB). The nurse should notify the health care provider if the patient exhibits which finding?
- A. Yellow-tinged skin
- B. Orange-colored sputum
- C. Thickening of the fingernails
- D. Difficulty hearing high-pitched voices
Correct answer: Yellow-tinged skin
Rationale: The correct answer is 'Yellow-tinged skin.' Yellow-tinged skin is indicative of noninfectious hepatitis, a toxic effect of isoniazid (INH), rifampin, and pyrazinamide. If a patient on TB therapy develops hepatotoxicity, alternative medications will be necessary. Thickening of fingernails and difficulty hearing high-pitched voices are not typical side effects of the medications used in standard TB therapy. Presbycusis, age-related hearing loss, is common in older adults and not a cause for immediate concern. Orange-colored sputum is an expected side effect of rifampin and does not warrant immediate notification to the healthcare provider.
