NCLEX RN Practice Questions With Rationale
1. Who owns a patient's x-rays?
- A. The patient
- B. The doctor
- C. The facility that performed the procedure
- D. None of the above
Correct answer: C
Rationale: X-rays are typically owned by the facility that conducts the procedure, not the patient or the doctor. The facility that performs the procedure is responsible for maintaining and storing the x-rays as part of the patient's medical records. The patient does not own the x-rays since they are part of their medical record and not a physical possession. The doctor also does not own the x-rays as they are generated as a result of the medical procedure conducted at the facility, making choice C the correct answer.
2. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?
- A. Uncompensated respiratory acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic acidosis
- D. Compensated metabolic alkalosis
Correct answer: A
Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.
3. A client has volunteered to take part in a research study. After participating for two months, he decides that he can no longer tolerate the study and decides to leave. What are the client's rights in this situation?
- A. The client has a right to be released from the study but must reimburse the researchers for charges incurred
- B. The client has a right to be released from the study without any liability
- C. The client has a right to be released from the study but is prohibited from participating in any future studies
- D. The client does not have the right to be released from the study; he must finish his participation
Correct answer: B
Rationale: When a client voluntarily participates in a research study and later decides to withdraw, they have the right to be released from the study without any liability. It is unethical to force a participant to continue in a study against their will as this violates their autonomy and personal rights. Choice A is incorrect as it suggests that the client must reimburse the researchers for charges incurred, which is not typically the case unless agreed upon beforehand. Choice C is incorrect as there is no standard practice prohibiting a participant from future studies just because they withdrew from a current one. Choice D is incorrect because participants always have the right to withdraw from a research study at any time.
4. What kind of preventive measures is MOST likely to be used to prevent Mary Eden from falling due to her muscular frailty?
- A. Physical therapy for muscle strengthening exercises
- B. Physical therapy for range of motion exercises
- C. Occupational therapy to help her with confusion
- D. Medications to help her sleep more
Correct answer: A
Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.
5. Which of the following components is associated with hypertonic dehydration?
- A. Plasma sodium levels above 150 mEq/L
- B. Fluid moves from extracellular space to intracellular space
- C. Water loss is greater than electrolyte loss
- D. Physical signs and symptoms are grossly apparent
Correct answer: C
Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.
