NCLEX RN Exam Review Answers
1. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?
- A. Induce vomiting
- B. Hold the next dose of Lithium
- C. Administer an antiemetic
- D. Give the next dose of Lithium
Correct answer: B
Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.
2. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:
- A. Lack of thirst
- B. Pale skin
- C. Hypertension
- D. Swollen tongue
Correct answer: D
Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.
3. Septic, anaphylactic, and neurogenic shock are all categorized as:
- A. Hypovolemic shock
- B. Cardiogenic shock
- C. Distributive shock
- D. Obstructive shock
Correct answer: C
Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
4. A patient is being discharged from the med-surgical unit. The patient has a history of gastritis. The nurse questions the patient on their usual routine at home. Which of these statements would alert the nurse that additional teaching is required?
- A. I avoid NSAIDs. I only take a daily aspirin for my heart health.
- B. I always avoid eating hot and spicy foods.
- C. I will continue taking my antacids with or immediately after meals.
- D. I will only drink coffee once a week, if even that often.
Correct answer: A
Rationale: The correct answer is, 'I avoid NSAIDs. I only take a daily aspirin for my heart health.' Aspirin is classified as an NSAID and can exacerbate existing stomach problems, such as gastritis. Therefore, patients with gastritis should avoid aspirin just like any other NSAID. Choice B, 'I always avoid eating hot and spicy foods,' is a good practice for a patient with gastritis. Choice C, 'I will continue taking my antacids with or immediately after meals,' indicates understanding of the correct timing for antacid use. Choice D, 'I will only drink coffee once a week, if even that often,' shows a suitable limitation of coffee intake, which is beneficial for patients with gastritis.
5. 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.
