1. 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).

2. During a seizure, what is the primary intervention?

• A. Protect the patient from injury
• B. Insert an airway
• C. Elevate the head of the bed
• D. Withdraw all pain medications

Correct answer: A

Rationale: The primary intervention during a seizure is to protect the patient from injury. This involves creating a safe environment by moving harmful objects away, cushioning the head, and staying with the patient until the seizure ends. Inserting an airway is only necessary if the patient's airway is obstructed, not routinely during a seizure. Elevating the head of the bed is not a priority during an active seizure as it won't affect the seizure's outcome. Withdrawing all pain medications is not a standard practice unless there are specific contraindications related to the seizure itself.

3. A healthcare professional is preparing to administer an autologous blood product to a client. Which of the following actions should the professional take to identify the client?

• A. Match the client's blood type with the type and cross-match specimens
• B. Confirm the provider's prescription matches the number on the blood component
• C. Ask the client to state their blood type and the date of their last blood donation
• D. Ensure that the client's identification band matches the number on the blood unit

Correct answer: A

Rationale: When preparing to administer an autologous blood product, it is crucial to correctly identify the client to prevent errors. Matching the client's blood type with the type and cross-match specimens ensures that the blood product is intended for the correct recipient. This step helps in verifying the patient's identity and avoiding any transfusion-related complications. Confirming the blood type through type and cross-matching is a standard practice to ensure patient safety during blood transfusions.

4. Which of the following vascular system changes result from aging?

• A. Increased peripheral resistance of the blood vessels
• B. Decreased blood flow
• C. Increased workload of the left ventricle
• D. All of the above

Correct answer: D

Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.

5. A client has generalized petechiae and ecchymoses. The nurse should expect a prescription for which of the following laboratory tests?

• A. Platelet count
• B. Potassium level
• C. Creatinine clearance
• D. Prealbumin

Correct answer: A

Rationale: Generalized petechiae and ecchymoses can indicate a potential issue with platelet function or count. Therefore, the most relevant laboratory test to evaluate this condition would be a platelet count. Platelet count helps assess the number of platelets in the blood, which are crucial for clotting and preventing bleeding. Monitoring platelet levels can provide important information about a client's bleeding risk and overall hematologic health.
