Extract:
Question 1 of 5
A nurse is teaching a class about oxygen transport in the circulatory system. Which of the following transports oxygen in the blood?
Correct Answer: C
Rationale: Hemoglobin in red blood cells transports oxygen. Platelets aid clotting, neutrophils fight infection, and lymphocytes support immunity.
Question 2 of 5
A nurse is caring for a client with a pre-existing cardiovascular disease and atrial fibrillation. What type of stroke is this client at increased risk to have?
Correct Answer: C
Rationale: Atrial fibrillation increases embolic stroke risk due to heart clots traveling to the brain. Hemorrhagic, thrombotic, and subarachnoid strokes are less directly linked.
Question 3 of 5
A nurse in the operating room is caring for a client who suddenly develops muscle rigidity and a rise in body temperature. What emergency medication should the nurse expect to receive an order to start administering?
Correct Answer: A
Rationale: Dantrolene treats malignant hyperthermia, indicated by rigidity and hyperthermia. Neostigmine, vecuronium, and naloxone address other conditions.
Question 4 of 5
A nurse receives an order from the provider for a client requiring the highest oxygen concentration with a one-way valve. What type of mask should the nurse apply to the client?
Correct Answer: C
Rationale: A non-rebreather mask delivers nearly 100% oxygen with a one-way valve to prevent rebreathing. Simple and partial rebreather masks lack this, and Venturi delivers precise, lower concentrations.
Question 5 of 5
A nurse is preparing to administer amoxicillin 320 mg PO every 12 hours to an infant. The amount available is amoxicillin suspension 400 mg/5 mL. How many mL should the nurse administer per dose?
Correct Answer: B
Rationale: Calculate: 400 mg/5 mL = 80 mg/mL. For 320 mg, 320 ÷ 80 = 4 mL per dose.
