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. A patient with Addison's disease asks a nurse for nutrition and diet advice. Which of the following diet modifications is not recommended?

• A. A diet high in grains
• B. A diet with adequate caloric intake
• C. A high protein diet
• D. A restricted sodium diet

Correct answer: D

Rationale: For a patient with Addison's disease, a restricted sodium diet is not recommended. These patients require normal dietary sodium to prevent excess fluid loss. Patients with primary adrenal insufficiency (Addison disease) should have ample access to salt because of the salt wasting that occurs if their condition is untreated. Therefore, a diet high in grains, a diet with adequate caloric intake, and a high protein diet are all recommended for patients with Addison's disease to support their nutritional needs and overall health. However, restricting sodium can be detrimental for these patients due to the nature of their condition.

3. A complication of osteoporosis is _______________?

• A. rheumatoid arthritis
• B. gouty arthritis
• C. dorsiflexion
• D. joint deformity

Correct answer: D

Rationale: Joint deformity is a well-known complication of osteoporosis, leading to structural changes in the joints due to bone loss and fragility. Gouty arthritis and rheumatoid arthritis are distinct types of arthritis that are not direct complications of osteoporosis. Dorsiflexion is a movement related to the foot's range of motion and is not a typical complication of osteoporosis.

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. Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.

• A. nosocomial
• B. systemic
• C. resident flora
• D. resident aura

Correct answer: A

Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
