Nursing Elites

1. 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.

2. You are caring for a patient with newly diagnosed multiple sclerosis. Discharge instructions will likely include all of the following EXCEPT:

• A. PT referral for development of a planned exercise program
• B. Avoidance of prolonged sun exposure
• C. Hot baths to promote muscle relaxation
• D. Instructions to evaluate the home environment to ensure safety

Correct answer: C

Rationale: Discharge instructions for a patient with newly diagnosed multiple sclerosis should focus on promoting safety and minimizing exacerbations. Hot baths should be avoided as excessive heat can trigger acute symptoms. Therefore, instructions may include PT referral for an exercise program to maintain mobility, avoidance of prolonged sun exposure to prevent symptom exacerbation, and guidance to evaluate the home environment for safety as symptoms progress. Hot baths are not recommended due to the risk of exacerbating symptoms, making it the correct answer. Choices A, B, and D are appropriate for a patient with multiple sclerosis, as they address mobility, symptom management, and safety concerns, respectively.

3. 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.

4. Who among the following individuals wrote a medical code of ethics?

• A. Hammurabi
• B. Thomas Percival
• C. Hippocrates
• D. All of the above

Correct answer: D

Rationale: All of the above individuals contributed to the development of medical ethics. Hammurabi created the earliest known code around 2500 BC. Hippocrates, known for the principle 'Do no harm,' emphasized ethical practices in medicine. Thomas Percival, a physician interested in sociological medicine, authored a Code of Medical Ethics in 1803, which influenced modern medical ethics. Therefore, the correct answer is 'All of the above.' Choices A, B, and C are incorrect because each of them individually wrote a medical code of ethics, making 'All of the above' the most inclusive and accurate answer.

5. Which of the following statements best describes compartment syndrome?

• A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
• B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
• C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
• D. An injury causes pain and swelling of the median plantar nerve.

Correct answer: B

Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.
