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. If a patient's blood pressure is 150/96, what is his pulse pressure?

• A. 54
• B. 96
• C. 150
• D. 246

Correct answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

3. Studies have shown that about 40% of patients fall out of bed despite the use of side rails; this has led to which of the following conclusions?

• A. Side rails are ineffective
• B. Side rails should not be used
• C. Side rails are a deterrent that prevents a patient from falling out of bed
• D. Side rails are a reminder to a patient not to get out of bed

Correct answer: D

Rationale: The correct conclusion drawn from the study is that side rails serve as a reminder to the patient not to get out of bed rather than being a fail-proof preventive measure against falls. While they may not entirely prevent falls, they play a role in prompting the patient to be cautious when moving.

4. Which of the following patients is at greater risk for contracting an infection?

• A. A patient with leukopenia
• B. A patient receiving broad-spectrum antibiotics
• C. A postoperative patient who has undergone orthopedic surgery
• D. A newly diagnosed diabetic patient

Correct answer: A

Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.

5. A 38-year-old patient’s vital signs at 8 a.m. are axillary temperature 99.6°F (37.6°C); pulse rate 88; respiratory rate 30. Which findings should be reported?

• A. Respiratory rate only
• B. Temperature only
• C. Pulse rate and temperature
• D. Temperature and respiratory rate

Correct answer: D

Rationale: Both an elevated temperature and an increased respiratory rate are abnormal vital signs that could indicate an underlying health issue. Reporting both of these findings is crucial to ensure appropriate evaluation and intervention if needed.
