NCLEX RN Exam Review Answers
1. A client needs to give informed consent for electroconvulsive therapy treatments. Which of the following actions should the nurse take?
- A. Explain the adverse effects the client might experience from the treatment
- B. Verify the client gave consent voluntarily for the treatment
- C. Describe the benefits of the treatment to the client
- D. Outline possible alternatives to the treatment for the client
Correct answer: B
Rationale: When obtaining informed consent for a procedure like electroconvulsive therapy, the nurse's primary responsibility is to ensure that the client has given consent voluntarily and is capable of making such a decision. While it is essential to provide information on the treatment's benefits, risks, and alternatives, the priority is to verify the client's voluntary consent. Explaining the adverse effects and describing the benefits are important steps in the informed consent process, but the critical step is to confirm the client's voluntary agreement. Outlining possible alternatives to the treatment is also important but comes after ensuring the client's voluntary consent.
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. While assessing a one-month-old infant, which of the findings does not warrant further investigation by the nurse?
- A. Abdominal respirations
- B. Inspiratory grunt
- C. Nasal flaring
- D. Cyanosis
Correct answer: A
Rationale: Abdominal respirations in infants are considered normal due to the underdeveloped intercostal muscles. Infants rely more on their abdominal muscles to facilitate breathing since their intercostal muscles are not fully matured. Therefore, abdominal respirations do not typically require further investigation. Inspiratory grunt, nasal flaring, and cyanosis are findings that warrant additional assessment as they can indicate potential respiratory distress or other underlying health issues in infants. Inspiratory grunt may suggest respiratory distress, nasal flaring can be a sign of increased work of breathing, and cyanosis indicates poor oxygenation, all of which require prompt evaluation and intervention to ensure the infant's well-being.
4. The discharge planning team is discussing plans for the dismissal of a 16-year-old admitted for complications associated with asthma. The client's mother has not participated in any of the discharge planning processes but has stated that she wants to be involved. Which of the following reasons might prohibit this mother from participating in discharge planning?
- A. The client is an emancipated minor
- B. The mother has to work and is unavailable
- C. The client has a job and a driver's license
- D. The mother does not speak English
Correct answer: A
Rationale: In this scenario, the correct answer is that the client is an emancipated minor. Emancipated minors, even if they are under the age of 18, have the legal right to make decisions about their own healthcare and planning, which may include not wanting their parent involved in the discharge planning process. This status grants them independence from parental involvement in certain situations. The other choices are incorrect because the mother's work schedule, the client's job and possession of a driver's license, and the mother's language proficiency do not inherently prevent her from participating in the discharge planning process, unlike the legal status of being an emancipated minor.
5. Which of the following is a true statement about assessing blood pressure by palpation?
- A. Only the diastolic blood pressure can be assessed through palpation.
- B. The palpation technique is most useful for infants and small children.
- C. Hypertension is a common condition that might need to be assessed through blood pressure palpation.
- D. Only the systolic blood pressure can be assessed through palpation.
Correct answer: D
Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.
