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 client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?

• A. Elevated fibrinogen level
• B. Prolonged PT
• C. Elevated platelet count
• D. Depressed d-dimer level

Correct answer: B

Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.

3. 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.

4. Which of the following is an example of whistle-blowing?

• A. A nurse contacts administration about a colleague who takes supplies to use for a mission trip
• B. A client sues a nurse because she failed to call the physician about his wound infection
• C. A nursing assistant calls for help when a client falls out of bed
• D. A client developed a sacral pressure ulcer when he was not turned in bed for over four hours

Correct answer: A

Rationale: Whistle-blowing involves notifying administration or a supervisor about unethical or illegal activities. In this scenario, the nurse reporting a colleague taking supplies for personal use is an example of whistle-blowing as it involves reporting behavior that is dishonest and potentially harmful. Choices B, C, and D do not represent whistle-blowing. Choice B involves a legal action by a client against a nurse, choice C is a situation where immediate care is provided, and choice D is a case of neglect that should have been prevented.

5. Richard is a 72-year-old with stage 4 lung cancer who has been admitted to the hospital for pneumonia. He is alert and oriented and states he would like to sign a do not resuscitate (DNR) order. His wife enters the room after he has signed it and is very upset that he has made this decision without discussing it with her. She wants to know what she can do to get the DNR reversed. What should your first response be?

• A. Contact the unit manager to talk with her
• B. Contact the hospital's attorney to discuss with her
• C. Try to talk Richard out of his decision
• D. Offer caring support for both parties

Correct answer: D

Rationale: The correct response in this situation is to offer caring support for both parties. Richard, being alert and oriented, has the right to make his own decisions, including signing a do not resuscitate (DNR) order. It is important to respect his autonomy while also acknowledging his wife's feelings. By offering caring support, the nurse can facilitate a discussion between Richard and his wife, helping them navigate their emotions and decisions. Contacting the unit manager or hospital's attorney would not be appropriate as the initial response. These actions may escalate the situation and are not focused on addressing the emotional needs of the couple. Trying to talk Richard out of his decision would disregard his autonomy and right to make choices about his own care, which goes against ethical principles of patient autonomy and informed decision-making.
