NCLEX RN Exam Review Answers
1. Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?
- A. Septic shock
- B. Hypovolemic shock
- C. Neurogenic shock
- D. Cardiogenic shock
Correct answer: B
Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.
2. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)
- A. Age
- B. Blood pressure
- C. Respiratory rate
- D. Oxygen saturation
Correct answer: D
Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.
3. A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?
- A. Try to reposition the hearing aid
- B. Change the batteries
- C. Remove the device and have it cleaned
- D. Notify the physician that the hearing aid is not working
Correct answer: A
Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.
4. A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?
- A. Arrange to change client care assignments
- B. Explain that this behavior is expected
- C. Discuss the appropriate use of 'time-out'
- D. Explain that the child needs extra attention
Correct answer: B
Rationale: When encountering a 16-month-old child exhibiting fear of strangers by clinging to the parent and crying, it is essential for the nurse to explain that this behavior is expected. Fear of strangers typically emerges around 6-8 months of age and can continue into the toddler years and beyond. This behavior is a normal part of development as the child is displaying attachment and trust in familiar caregivers. Changing client care assignments, discussing 'time-out,' or suggesting the child needs extra attention are not appropriate initial actions in this situation. Changing care assignments is unnecessary and does not address the child's emotional needs. Discussing 'time-out' is not relevant as it pertains to discipline strategies for older children. Suggesting the child needs extra attention may misinterpret the situation; the child's behavior is a normal response to a new environment and does not necessarily indicate a need for additional attention.
5. The nurse provides preoperative instruction for a patient scheduled for a left pneumonectomy for lung cancer. Which information should the nurse include about the patient's postoperative care?
- A. Positioning on the right side
- B. Bed rest for the first 24 hours
- C. Frequent use of an incentive spirometer
- D. Chest tube placement with continuous drainage
Correct answer: C
Rationale: After a pneumonectomy, frequent deep breathing and coughing are essential to prevent atelectasis and promote gas exchange. Patients are typically positioned on the surgical side to aid in gas exchange. Early mobilization is crucial to reduce the risk of postoperative complications such as pneumonia and deep vein thrombosis. While chest tubes may or may not be placed in the surgical space, if used, they are clamped and only adjusted by the surgeon to manage serosanguineous fluid accumulation. Overfilling of the chest cavity can compromise remaining lung function and cardiovascular status. Chest x-rays are useful for monitoring fluid volume and space postoperatively. Therefore, the correct postoperative care instruction for the patient undergoing a left pneumonectomy is the frequent use of an incentive spirometer. Choices A, B, and D are incorrect as positioning on the right side, bed rest for the first 24 hours, and continuous chest tube drainage are not standard postoperative care practices for patients undergoing pneumonectomy.
