1. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

2. What is the function of the epiglottis during swallowing?

• A. Prevents food from entering the trachea
• B. Aids in food propulsion
• C. Enhances taste sensation
• D. Lubricates the esophagus

Correct answer: A

Rationale: The epiglottis is a flap of tissue that closes over the trachea during swallowing to prevent food and liquids from entering the airway. Choice A is correct because the primary function of the epiglottis is to act as a lid over the trachea, ensuring that food goes down the esophagus and not into the windpipe. Choices B, C, and D are incorrect as they do not describe the specific role of the epiglottis during swallowing.

3. There has been a serious explosion at a local factory, and many of the injured are arriving at the hospital. Which of the following patients should a nurse attend to first?

• A. A 30-year-old male who is able to walk into the hospital on his own but has numerous lacerations on the chest and face
• B. A 45-year-old male who was brought in on a stretcher, has been assessed as having respiration and circulation within normal limits, and can follow simple commands
• C. A 50-year-old woman who can walk but has a broken arm and numerous lacerations
• D. A 19-year-old man who has numerous lacerations all over the body and whose respiration exceeds 30 breaths per minute

Correct answer: D

Rationale: The correct answer is D. The 19-year-old man with a respiration rate exceeding 30 breaths per minute is showing signs of respiratory distress, indicating a potentially life-threatening condition that requires immediate attention. Patients with respiratory distress should be prioritized as it is a critical condition. Choices A, B, and C describe patients with injuries that are less immediately life-threatening or who are more stable based on the provided information, so they can be attended to after the patient with respiratory distress. Therefore, the nurse should attend to the 19-year-old man first to address his respiratory distress and ensure his condition does not deteriorate further.

4. Based on the computer documentation in the EMR, which action should the PN implement?

• A. Give the rubella vaccine subcutaneously
• B. Observe the mother breastfeeding her infant
• C. Call the nursery for the infant's blood type results
• D. Administer hydrocodone/acetaminophen one tablet for pain

Correct answer: A

Rationale: The rubella vaccine is crucial for preventing rubella infection, which can cause severe congenital disabilities if contracted during pregnancy. Administering the vaccine subcutaneously is the correct action based on EMR documentation. Observing breastfeeding, calling the nursery for blood type results, and administering pain medication are not indicated by the EMR documentation and are not relevant to the situation described in the question.

5. During a blood transfusion, which sign or symptom should prompt the healthcare provider to immediately stop the transfusion?

• A. Slight increase in blood pressure
• B. Elevated temperature and chills
• C. Mild nausea
• D. Slight headache

Correct answer: B

Rationale: The correct answer is B: Elevated temperature and chills. These symptoms are indicative of a transfusion reaction, which can be severe and life-threatening. It is crucial to stop the transfusion immediately and notify the healthcare provider for further assessment and management. Elevated temperature and chills are classic signs of a transfusion reaction, specifically indicating a possible febrile non-hemolytic reaction. Choice A, a slight increase in blood pressure, is not typically a reason to stop a transfusion unless it is a significant sudden increase. Mild nausea (Choice C) and a slight headache (Choice D) are common side effects of blood transfusions and are not primary indicators of a transfusion reaction that require immediate cessation of the transfusion.
