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 born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?

• A. Start the hepatitis B immunization series.
• B. Teach the patient about hepatitis A immune globulin.
• C. Ask whether the patient has been screened for hepatitis C.
• D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).

Correct answer: C

Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.

3. 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.

4. The nurse is providing disease prevention education to a 63-year-old woman with a negative family history of breast cancer. The nurse recommends the patient schedule mammograms with which frequency?

• A. Every 5 years
• B. Every 10 years
• C. Every other year
• D. Once a year

Correct answer: C

Rationale: Mammograms, along with breast self-examinations and other routine tests, are key for the early diagnosis and treatment of breast cancer. All major societies (WHO, ACS, USPSTF) recommend a screening mammogram every two years in women of this age at average risk of breast cancer. The recommended frequency may change if there are identified family history and significant risk factors. Choosing 'Once a year' is too frequent and not aligned with current guidelines. Opting for 'Every 5 years' or 'Every 10 years' intervals is not adequate for regular breast cancer screening and may increase the risk of cancer progression. Therefore, 'Every other year' is the most appropriate choice for this patient without a family history of breast cancer.

5. In a clinic in a primarily African American community, a higher incidence of uncontrolled hypertension is noted in patients. To correct this health disparity, what should the nurse do first?

• A. Initiate a regular home-visit program by clinic nurses.
• B. Schedule teaching sessions about low-salt diets at community events.
• C. Assess the perceptions of community members about the care at the clinic.
• D. Obtain low-cost antihypertensive drugs using government grant funding.

Correct answer: C

Rationale: To address the higher incidence of uncontrolled hypertension in the primarily African American community, the nurse should first assess the perceptions of community members about the care at the clinic. Understanding the community's perspective can provide valuable insights into the reasons behind the health disparity. Initiating a regular home-visit program or scheduling teaching sessions about low-salt diets are important interventions but should come after gathering information on community perceptions. Obtaining low-cost antihypertensive drugs is not the initial priority; understanding community perspectives is crucial for developing effective interventions.
