1. 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.

2. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

3. How many liters are equal to 1800 ml?

• A. 1.8
• B. 18000
• C. 180
• D. 2800

Correct answer: A

Rationale: To convert milliliters (ml) to liters, divide by 1000 since 1 liter is equal to 1000 ml. Therefore, 1800 ml is equal to 1800/1000 = 1.8 liters. Choice A (1.8) is correct. Choice B (18000) is incorrect as it equates to 18000 liters, not 1.8 liters. Choice C (180) is incorrect as it represents 180 liters, not 1.8 liters. Choice D (2800) is incorrect as it does not reflect the conversion of 1800 ml to liters.

4. A nurse is orienting a newly licensed nurse on performing a routine assessment of a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following information should the nurse include in the teaching?

• A. Apply a vest restraint if self-extubation is attempted.
• B. Monitor ventilator settings every 8 hours.
• C. Document tube placement in centimeters at the angle of the jaw.
• D. Assess breath sounds every 1 to 2 hours.

Correct answer: D

Rationale: Assessing breath sounds every 1 to 2 hours is crucial in monitoring the client's respiratory status and identifying any potential complications promptly. Monitoring ventilator settings every 8 hours is important for overall ventilation management. Documenting the endotracheal tube placement accurately is essential to ensure proper positioning. Using a vest restraint if self-extubation is attempted is not a recommended intervention as it can lead to complications and should be avoided.

5. The physician orders a platelet count to be performed on Mrs. Smith after breakfast. The nurse is responsible for:

• A. Instructing the patient about this diagnostic test
• B. Writing the order for this test
• C. Giving the patient breakfast
• D. All of the above

Correct answer: A

Rationale: The nurse's responsibility in this scenario is to instruct the patient about the diagnostic test ordered by the physician. This includes explaining the purpose of the test, any necessary preparations, and what to expect. The nurse is not responsible for writing the order, as this is the physician's role. Additionally, providing breakfast is not directly related to the platelet count test. Therefore, the correct answer is A, which aligns with the nurse's role in educating and supporting the patient regarding the test.
