Nursing Elites

1. 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.

2. 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.

3. Which of the following clients is most likely ready to be dismissed from an inpatient care setting to home?

• A. A 65-year old male with urine output of 60cc in the past four hours
• B. A 2-month old female with a temperature of 100.6 rectally
• C. A 38-year old female who transitioned from IV TPN to full liquids six hours ago
• D. A 4-year old male with an oxygen saturation of 96% on room air

Correct answer: D

Rationale: Clients must meet a certain amount of set criteria before they will be discharged from a healthcare facility. Although guidelines may vary between locations, most healthcare facilities expect clients to have adequate oxygenation, nutrition, and elimination; and be free from fever, vomiting, and significant pain

4. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?

• A. Ensure that the client does not need surgery
• B. Assess the client's grip strength
• C. Perform an Allen test
• D. Check a serum potassium level

Correct answer: C

Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.

5. One of the complications of complete bed rest and immobility is which of the following?

• A. Plantar flexion
• B. Dorsiflexion
• C. Extension contractures
• D. Adduction contractures

Correct answer: A

Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.
