NCLEX RN Practice Questions Exam Cram
1. A nurse is caring for a 2-year-old child after corrective surgery for Tetralogy of Fallot. The mother reports that the child has suddenly begun seizing. The nurse recognizes this problem is probably due to
- A. A cerebral vascular accident
- B. Postoperative meningitis
- C. Medication reaction
- D. Metabolic alkalosis
Correct answer: A
Rationale: The correct answer is a cerebral vascular accident. Polycythemia occurs as a physiological reaction to chronic hypoxemia, which commonly occurs in clients with Tetralogy of Fallot. Polycythemia and the resultant increased viscosity of the blood increase the risk of thromboembolic events, including cerebrovascular accidents. Signs and symptoms of a cerebral vascular accident include sudden paralysis, altered speech, extreme irritability or fatigue, and seizures. Postoperative meningitis (choice B) is less likely in this scenario as the sudden onset of seizing is more indicative of a vascular event rather than an infection. Medication reaction (choice C) is not the most probable cause given the history provided. Metabolic alkalosis (choice D) is not associated with sudden seizing in this context.
2. A systolic blood pressure of 145 mm Hg is classified as:
- A. Normotensive
- B. Prehypertension
- C. Stage I hypertension
- D. Stage II hypertension
Correct answer: C
Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.
3. Which of the following measures would be appropriate for a nurse to teach the parent of a nine-month-old infant about diaper dermatitis?
- A. Use only cloth diapers that are rinsed in bleach
- B. Do not use occlusive ointments on the rash
- C. Use commercial baby wipes with each diaper change
- D. Discontinue a new food that was added to the infant's diet just prior to the rash
Correct answer: D
Rationale: Diaper dermatitis can be caused by various factors, one of which includes introducing new foods to the infant's diet. Discontinuing the new food that was added just before the rash can help identify and eliminate the potential cause. Options A and C are not directly related to addressing the cause of diaper dermatitis. While using cloth diapers rinsed in bleach may be a preventive measure for diaper dermatitis, it is not addressing a specific cause. Option B, advising against using occlusive ointments on the rash, may actually be beneficial in managing diaper dermatitis, but it does not address the cause of the condition.
4. An infant has just returned to the nursing unit after surgical repair of a cleft lip on the right side. The nurse should place the infant in which best position at this time?
- A. Prone position
- B. On the stomach
- C. Left lateral position
- D. Right lateral position
Correct answer: C
Rationale: After surgical repair of a cleft lip on the right side, the nurse should position the infant carefully to ensure comfort and prevent complications. Placing the infant in the prone position or on the stomach is not recommended as it may cause rubbing of the surgical site against the mattress. The optimal position for the infant is the left lateral position, away from the surgical repair site, to minimize the risk of trauma. Placing the infant on the right lateral position would be contraindicated as it is on the side of the repair. Additionally, positioning the infant upright on the back can help prevent airway obstruction by secretions, blood, or the tongue. Therefore, the correct choice is to place the infant in the left lateral position to promote safety and comfort post cleft lip surgery.
5. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?
- A. 60 microdrops/minute
- B. 20 microdrops/minute
- C. 30 microdrops/minute
- D. 40 microdrops/minute
Correct answer: A
Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
