NCLEX RN Exam Review Answers
1. You are caring for a group of elderly clients, many of whom are affected by multiple chronic disorders and are also, at times, affected by some acute disorders that require medical and nursing attention. As you are caring for these clients, some will need a new medication regimen for an acute disorder. You should consider the fact that the elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to the elderly having a(n):
- A. Increased creatinine clearance.
- B. Impaired immune system.
- C. Decreased hepatic metabolism.
- D. Increased bodily fat
Correct answer: C
Rationale: The correct answer is 'Decreased hepatic metabolism.' The elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to a decrease in hepatic metabolism. This is caused by changes in hepatic functioning in the elderly, including decreased hepatic blood flow and functioning. Choice A, 'Increased creatinine clearance,' is incorrect as aging typically results in decreased, not increased, creatinine clearance. Choice B, 'Impaired immune system,' is not directly related to the increased risk of adverse drug reactions in the elderly. Choice D, 'Increased bodily fat,' is not a primary factor contributing to the increased risk of medication-related issues in the elderly population.
2. The nurse is assessing an infant with developmental dysplasia of the hip. Which finding would the nurse anticipate?
- A. Unequal leg length
- B. Limited adduction
- C. Diminished femoral pulses
- D. Symmetrical gluteal folds
Correct answer: A
Rationale: The correct answer is 'Unequal leg length.' Shortening of a leg is a common sign of developmental dysplasia of the hip. Limited adduction (Choice B) may be present but is less specific to developmental dysplasia of the hip. Diminished femoral pulses (Choice C) are not typically associated with developmental dysplasia of the hip. Symmetrical gluteal folds (Choice D) are a normal finding and would not be expected in a patient with developmental dysplasia of the hip.
3. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct answer: B
Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.
4. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
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.
