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. A patient is suspected to have sustained a spinal cord injury. What best describes the overarching principles used to guide the care for this type of condition?
- A. Immobilize the cervical area to prevent further injury
- B. Monitor the patient's level of consciousness to prevent neurologic deterioration
- C. Help the patient with activities of daily living and provide emotional and physical support to help them adjust to their injury
- D. Facilitate tissue perfusion to the spinal cord while maintaining airway and breathing
Correct answer: D
Rationale: The correct answer is to facilitate tissue perfusion to the spinal cord while maintaining airway and breathing. In the acute phase of a spinal cord injury, ensuring proper tissue perfusion to the spinal cord is crucial to prevent further damage. Maintaining airway, breathing, and circulation is essential in guiding the overall care for a patient with a spinal cord injury. Choices A, B, and C, while important in certain aspects of care, are not the overarching principles that guide the immediate management of a suspected spinal cord injury.
3. The major difference between a grand mal and petit mal seizure is that a person with a grand mal seizure will have _______________ and the person with a petit mal seizure will not.
- A. convulsive movements
- B. sleep apnea
- C. atonic movements
- D. flaccidity
Correct answer: A
Rationale: The major difference between a grand mal and petit mal seizure is the presence or absence of convulsive movements. Grand mal seizures are characterized by convulsive movements, including jerking of limbs and loss of consciousness. In contrast, petit mal seizures, also known as absence seizures, typically involve brief episodes of staring or eye blinking without convulsive movements. Therefore, choice A, 'convulsive movements,' is the correct answer. Choices B, 'sleep apnea,' and D, 'flaccidity,' are incorrect as they are not associated with the characteristics of grand mal or petit mal seizures. Choice C, 'atonic movements,' is also incorrect as petit mal seizures do not involve atonic movements, but rather absence behaviors such as staring spells.
4. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?
- A. Decreased cardiac output can cause hypoxia to the brain
- B. Mental status changes may be a side effect of the patient's medication
- C. Mitral regurgitation is a complication associated with some neurological disorders
- D. The patient may be confused about his diagnosis
Correct answer: A
Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.
5. A thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect?
- A. Atherosclerosis
- B. Diabetic nephropathy
- C. Autonomic neuropathy
- D. Somatic neuropathy
Correct answer: C
Rationale: In this case, the correct answer is autonomic neuropathy. Autonomic neuropathy affects the autonomic nerves, which control various bodily functions including the bladder. In diabetes, it can lead to bladder paralysis, resulting in symptoms like urgency to urinate and difficulty initiating urination. Atherosclerosis (choice A) is a condition involving the hardening and narrowing of arteries, not directly related to the inability to urinate in this context. Diabetic nephropathy (choice B) primarily affects the kidneys, leading to kidney damage, but does not typically cause urinary retention. Somatic neuropathy (choice D) involves damage to sensory nerves, not the autonomic nerves responsible for bladder control, making it less likely to be the cause of the urinary issue described in the question.
