1. 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.

2. After routine patient contact, how long should hand washing last at least?

• A. 30 seconds
• B. 1 minute
• C. 2 minutes
• D. 3 minutes

Correct answer: A

Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.

3. Which of the following is included in Orem’s theory?

• A. Maintenance of a sufficient intake of air
• B. Self-perception
• C. Love and belonging
• D. Physiological needs

Correct answer: A

Rationale: Orem's theory, also known as the Self-Care Deficit Nursing Theory, focuses on individuals' ability to perform self-care to maintain health and well-being. One specific component of this theory is the maintenance of a sufficient intake of air, which is crucial for sustaining life and overall health. Option A is the correct choice as it directly relates to meeting physiological needs, such as the intake of air, to support optimal functioning and health. Choices B, C, and D are incorrect as they do not specifically align with Orem's emphasis on self-care and meeting physiological requirements.

4. 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.

5. 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.
