NCLEX RN Practice Questions Exam Cram
1. The nurse provides home care instructions to the parents of a child with celiac disease. The nurse should teach the parents to include which food item in the child's diet?
- A. Rice
- B. Oatmeal
- C. Rye toast
- D. White bread
Correct answer: A
Rationale: In celiac disease, individuals are intolerant to gluten found in wheat, barley, rye, and oats. Therefore, it is crucial to eliminate these grains from the diet. Rice, corn, or millet are safe alternatives for individuals with celiac disease. Oatmeal is generally avoided unless specifically labeled as gluten-free due to possible cross-contamination. Rye toast and white bread contain gluten and should be avoided in celiac disease. Vitamin supplements may also be necessary to address deficiencies caused by dietary restrictions.
2. Why is it important to genotype HCV before initiating drug therapy?
- A. Side effects of nucleotide analogs
- B. Measures for improving the appetite
- C. Ways to increase activity and exercise
- D. Administering alpha-interferon (Intron A)
Correct answer: B
Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
3. 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.
4. A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child's symptoms?
- A. Possible fracture of the tibia.
- B. Bruising of the gastrocnemius muscle.
- C. Possible fracture of the radius.
- D. No anatomic injury, the child wants his mother to carry him.
Correct answer: A
Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.
5. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
