Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

3. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

4. When caring for a client in the advanced stage of amyotrophic lateral sclerosis (ALS), which of the following referrals is the nurse's priority?

• A. Psychologist
• B. Social worker
• C. Occupational therapist
• D. Speech-language pathologist

Correct answer: D

Rationale: In the advanced stage of ALS, speech and swallowing difficulties become significant. As a result, the priority referral for the nurse would be a speech-language pathologist. This professional can assist in managing communication challenges and provide strategies to address swallowing issues, ensuring the client's safety and quality of life.

5. What is a nurse's role in health promotion?

• A. Conducting health risk appraisals
• B. Educating clients to be effective health consumers
• C. Implementing worksite wellness programs
• D. None of the above

Correct answer: B

Rationale: A nurse plays a crucial role in health promotion by educating clients to be effective health consumers. This involves empowering individuals to make informed decisions about their health, access appropriate healthcare services, and engage in healthy behaviors to prevent illness and promote well-being. The other choices are not entirely accurate in describing the primary role of a nurse in health promotion. While nurses may conduct health risk appraisals and implement worksite wellness programs as part of their responsibilities, their central focus is on educating and empowering individuals to take control of their health.
