NCLEX RN Exam Review Answers
1. 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.
2. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?
- A. Anesthesia reaction
- B. Hyperglycemia
- C. Hypoglycemia
- D. Diabetic ketoacidosis
Correct answer: C
Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.
3. Parents of a 6-month-old breastfed baby ask the nurse about increasing the baby's diet. Which of the following should be added first?
- A. Cereal
- B. Eggs
- C. Meat
- D. Juice
Correct answer: A
Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.
4. Following assessment of a patient with pneumonia, the nurse identifies a nursing diagnosis of ineffective airway clearance. Which assessment data best supports this diagnosis?
- A. Weak, nonproductive cough effort
- B. Large amounts of greenish sputum
- C. Respiratory rate of 28 breaths/minute
- D. Resting pulse oximetry (SpO2) of 85%
Correct answer: A
Rationale: The correct answer is 'Weak, nonproductive cough effort.' A weak, nonproductive cough indicates that the patient is unable to clear the airway effectively, supporting the nursing diagnosis of ineffective airway clearance. In pneumonia, secretions can obstruct the airway, leading to ineffective clearance. Choices B, C, and D do not directly reflect ineffective airway clearance. Large amounts of greenish sputum (Choice B) may suggest infection or inflammation but do not specifically indicate ineffective airway clearance. The respiratory rate of 28 breaths/minute (Choice C) and a resting pulse oximetry (SpO2) of 85% (Choice D) are more indicative of impaired gas exchange or respiratory distress rather than ineffective airway clearance.
5. The clinic nurse is obtaining data about a child with a diagnosis of lactose intolerance. Which data should the nurse expect to obtain on assessment?
- A. Reports of frothy stools and diarrhea
- B. Reports of foul-smelling ribbon stools
- C. Reports of profuse, watery diarrhea and vomiting
- D. Reports of diffuse abdominal pain unrelated to meals or activity
Correct answer: A
Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.
