Questions on the Immune System Questions
Question 1 of 5
What are the actions of salicylates? (Select ONE that does not apply)
Correct Answer: D
Rationale: The correct answer is D, "Antihypertensive." Salicylates are not typically used for lowering blood pressure. Salicylates like aspirin are known for their anti-inflammatory, analgesic, and antipyretic actions. Salicylates inhibit prostaglandin synthesis which helps reduce inflammation, pain, and fever. Other choices are incorrect as salicylates are commonly used for these purposes.
Question 2 of 5
Which blood cell test is associated with risk of spontaneous hemorrhage if its counts fall below 10 x 10^9 /L?
Correct Answer: A
Rationale: Platelet count is the correct answer. Platelets are responsible for blood clotting, and a count below 10 x 10^9 /L can lead to spontaneous hemorrhage due to impaired clot formation. Hemoglobin, WBC, and RBC indices are not directly related to clotting function and do not pose the same risk of spontaneous hemorrhage.
Question 3 of 5
A nurse is providing teaching about lifestyle changes to a client who had a myocardial infarction and has a new prescription for a beta blocker. Which of the following client statements indicates an understanding of the teaching?
Correct Answer: A
Rationale: The correct answer is A because counting the radial pulse rate before taking the beta blocker is important to monitor for bradycardia, a potential side effect. This demonstrates understanding of the medication's effect. Option B is incorrect as increasing salt intake is contraindicated in heart conditions. Option C is incorrect as vigorous exercise is not recommended post-myocardial infarction. Option D is incorrect as stopping medication abruptly can be dangerous and is not recommended without medical advice.
Question 4 of 5
A nurse is caring for a client who has hemophilia. The client reports pain and swelling in a joint following an injury. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Correct Answer: A Rationale: 1. Hemophilia is a bleeding disorder due to missing clotting factors. 2. Pain and swelling in a joint indicate internal bleeding. 3. Replacement of the missing clotting factor is crucial to stop bleeding. 4. Administering aspirin can worsen bleeding due to its antiplatelet effects. 5. Applying heat can increase bleeding by dilating blood vessels. 6. Elevating the joint alone may not address the underlying bleeding issue.
Question 5 of 5
A nurse is preparing to transfuse a unit of packed red blood cells (RBCs) to a client who has anemia. Which of the following actions should the nurse take first?
Correct Answer: A
Rationale: The correct action is A: Witness the informed consent. This is the first step in the transfusion process to ensure the client's autonomy and understanding of the procedure. Without informed consent, the nurse cannot proceed with the transfusion. Checking the IV site (B) is important but not the first step. Verifying blood type (C) is crucial but can be done after obtaining consent. Priming the tubing (D) is necessary before starting the transfusion, but it comes after obtaining consent.
