NCLEX RN Exam Review Answers
1. Which question should the nurse ask the parents of a child suspected of having glomerulonephritis?
- A. Did your child fall off a bike onto the handlebars?
- B. Has the child had persistent nausea and vomiting?
- C. Has the child been itching or had a rash anytime in the last week?
- D. Has the child had a sore throat or a throat infection in the last few weeks?
Correct answer: D
Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Group A ?-hemolytic streptococcal infection is a common cause of glomerulonephritis. Children with glomerulonephritis often develop symptoms after a throat infection caused by streptococcal bacteria. Therefore, asking about a sore throat or throat infection in the last few weeks is crucial to assess the possible link to glomerulonephritis. Choices A, B, and C are not directly associated with the pathophysiology of glomerulonephritis. Asking about falling off a bike, nausea and vomiting, or itching and rash do not provide relevant information for assessing glomerulonephritis in this context.
2. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?
- A. It is the correct dose
- B. The dose is too low
- C. The dose is too high
- D. The dose should be increased or decreased, depending on the symptoms
Correct answer: B
Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.
3. The nurse assesses a patient suspected of having meningitis. Which of the following is a common clinical manifestation of this condition?
- A. A high WBC count and decreased level of consciousness
- B. A high WBC count and manic activity
- C. A low WBC count and manic activity
- D. A low WBC count and decreased level of consciousness
Correct answer: A
Rationale: The correct answer is 'A high WBC count and decreased level of consciousness.' Meningitis is often caused by an infectious organism, leading to an increase in Intracranial Pressure (ICP), which can result in decreased level of consciousness. While meningitis can trigger an inflammatory response, it typically presents with an elevated white blood cell (WBC) count rather than a low WBC count. Manic activity is not a common clinical manifestation of meningitis; instead, patients may exhibit altered mental status, confusion, or lethargy.
4. A 36-year-old male patient in the outpatient clinic is diagnosed with acute hepatitis C (HCV) infection. Which action by the nurse is appropriate?
- A. Schedule the patient for HCV genotype testing.
- B. Administer the HCV vaccine and immune globulin.
- C. Teach the patient about ribavirin (Rebetol) treatment.
- D. Explain that the infection will resolve over a few months.
Correct answer: A
Rationale: The correct action by the nurse is to schedule the patient for HCV genotype testing. Genotyping of HCV is crucial in determining the appropriate treatment regimen and guiding therapy decisions. Most patients with acute HCV infection progress to the chronic stage, so it is incorrect to inform the patient that the infection will resolve in a few months. There is no vaccine or immune globulin available for HCV, and ribavirin (Rebetol) is typically used for chronic HCV infection. Therefore, the nurse should prioritize genotyping to assist in treatment planning.
5. A client is undergoing radiation therapy for treatment of thyroid cancer. Following the radiation, the client develops xerostomia. Which of the following best describes this condition?
- A. Cracks in the corners of the mouth
- B. Peeling skin from the tongue and gums
- C. Increased dental caries
- D. Dry mouth
Correct answer: D
Rationale: Xerostomia, also known as dry mouth, is a common side effect of radiation therapy in the head and neck region. It occurs when the salivary glands are damaged during treatment, reducing saliva production and causing a dry sensation in the mouth. The correct answer is 'Dry mouth' (option D). Choice A, 'Cracks in the corners of the mouth,' describes angular cheilitis, a condition linked to nutritional deficiencies or candida infection. Choice B, 'Peeling skin from the tongue and gums,' is more indicative of conditions like oral thrush or mucositis. Choice C, 'Increased dental caries,' is a consequence of reduced saliva flow but does not specifically describe xerostomia.
