NCLEX RN Practice Questions With Rationale
1. The BRAT diet is often prescribed for patients with gastroenteritis. This acronym stands for:
- A. Bananas, Rice, Applesauce, and Toast
- B. Bread, Rice, Apricots, and Tapioca
- C. Bananas, Rolls, Apricots, and Toast
- D. Bananas, Rolls, Applesauce, and Tapioca
Correct answer: A
Rationale: The BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast, is commonly recommended for patients with gastroenteritis. These easily digestible foods help firm up stools due to their low fiber content and provide essential nutrients lost during vomiting and diarrhea. Choice B is incorrect because it includes apricots, which are not part of the traditional BRAT diet. Choice C is incorrect as it includes rolls, which are not typically included in the BRAT diet. Choice D is incorrect as it includes tapioca, which is not part of the traditional BRAT diet. Therefore, the correct answer is Bananas, Rice, Applesauce, and Toast.
2. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?
- A. The test determines if the client is anemic and needs iron supplements
- B. The test determines if there is excess glucose building up in the urine
- C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
- D. The test determines the amount of hemoglobin that is coated with glucose
Correct answer: D
Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
3. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.
- A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
- B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
- C. The client should lie flat on their back for a specific period following the procedure.
- D. The risks of the procedure include headache, back pain, and infection.
Correct answer: B
Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.
4. When teaching a client with coronary artery disease about nutrition, what should the nurse emphasize?
- A. Eating three balanced meals a day
- B. Adding complex carbohydrates
- C. Avoiding very heavy meals
- D. Limiting sodium intake to 7 g per day
Correct answer: C
Rationale: The correct answer is to emphasize avoiding very heavy meals. Eating large, heavy meals can divert blood away from the heart for digestion, potentially endangering clients with coronary artery disease. This practice may lead to an increased risk of plaque accumulation in the arteries, potentially obstructing the delivery of blood and oxygen to vital organs. Choices A, B, and D are incorrect. While eating three balanced meals a day, adding complex carbohydrates, and limiting sodium intake are generally good dietary practices, they are not the primary focus when teaching a client with coronary artery disease about nutrition. The emphasis should be on avoiding heavy meals that can strain the cardiovascular system.
5. A client diagnosed with schizophrenia is slow to respond and appears to be listening to unseen others. Which medication should a nurse expect a physician to order to address this type of symptom?
- A. Haloperidol (Haldol) to address the negative symptom
- B. Clonazepam (Klonopin) to address the positive symptom
- C. Risperidone (Risperdal) to address the positive symptom
- D. Clozapine (Clozaril) to address the negative symptom
Correct answer: C
Rationale: The correct medication to address the symptom described, where the client is slow to respond and appears to be listening to unseen others, is Risperidone (Risperdal). Risperidone is an atypical antipsychotic that is commonly used to manage positive symptoms of schizophrenia. Positive symptoms can include hallucinations, delusions, and disorganized thinking. Haloperidol (Haldol) and Clozapine (Clozaril) are typically used for addressing negative symptoms, such as lack of motivation or social withdrawal. Clonazepam (Klonopin) is a benzodiazepine primarily used for anxiety disorders and seizures, not for addressing symptoms of schizophrenia.
