1. 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.

2. Albert is a patient in the hospital who is scheduled for surgery the following morning. After the pre-operative visit from the anesthesia staff member who has obtained surgical consent, Albert asks for an explanation of what type of surgery he is going to have. He states that he's not sure what he just signed. What is your best response?

• A. Don't worry, they'll explain it in the operating room.
• B. It's standard procedure to get the consent; you don't need to worry.
• C. Let me ask the nurse anesthetist to come back and explain it further.
• D. Someone will review it with you prior to surgery.

Correct answer: C

Rationale: The correct response is to ensure that the patient fully understands the nature of the surgery they are about to undergo. If the patient expresses uncertainty about the procedure they signed consent for, it indicates a lack of informed consent, which is essential before any surgery. By requesting the nurse anesthetist to return and provide a more detailed explanation, the patient can make an informed decision. Choices A, B, and D do not address the issue of the patient's lack of understanding and the need for informed consent, making them incorrect. Option C is the best course of action to rectify the situation and ensure the patient's understanding and consent are properly obtained.

3. The client has a long leg cast. During discharge teaching about appropriate exercises for the affected extremity, the nurse should recommend:

• A. Isometric
• B. Range of motion
• C. Aerobic
• D. Isotonic

Correct answer: D

Rationale: The nurse should recommend isometric exercises for the muscles of the casted extremity. Isometric exercises involve contracting and relaxing muscles without moving the affected part. This type of exercise helps maintain muscle strength without moving the joint, which is important for clients with immobilized extremities. Range of motion exercises involve moving the joint through its full range of motion, which may not be suitable for a client with a long leg cast. Aerobic exercises focus on increasing cardiovascular endurance and may not be appropriate for a client with a casted extremity. Isotonic exercises involve muscle contractions with movement, which may not be safe for the affected extremity in a cast.

4. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

5. The nurse is discussing the need for early diagnosis and treatment of autism spectrum disorder (ASD) with parents of children suspected of having the condition. Which statement should the nurse include?

• A. Early diagnosis and treatment provide the only means for a cure of ASD.
• B. Early diagnosis and treatment gives your child the best chance of becoming a fully functioning adult.
• C. Early diagnosis and treatment provides the best way to ensure that your child can be admitted to an assisted living facility as an adult.
• D. Early diagnosis and treatment prevent your child from developing any other mental condition.

Correct answer: B

Rationale: The correct statement for the nurse to include is that early diagnosis and treatment provide the best chance for the child to become a fully functioning adult. It is important to educate parents that while early intervention can improve outcomes for individuals with ASD, it does not offer a cure but helps in managing symptoms and developing necessary skills. Choice A is incorrect as there is currently no cure for ASD. Choice C is inaccurate as early diagnosis and treatment focus on improving the child's quality of life and independence rather than ensuring admission to an assisted living facility. Choice D is incorrect as early diagnosis and treatment of ASD do not prevent the development of other mental health conditions; however, they can help in identifying and managing such conditions early on.
