1. The Sinoatrial Node (SA) is located within which of the following heart structures?

• A. Mitral Valve
• B. Right Ventricle
• C. Right Atrium
• D. Left Atrium

Correct answer: C

Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.

2. A patient has come to the office for a blood draw. The patient starts to sweat and is very anxious. Which of the following would be the BEST way to proceed?

• A. Do not perform the procedure. Notify the physician of the reason why.
• B. Perform the procedure but pay close attention for signs of potential syncope.
• C. Allow the patient to reschedule for a time when he isn't as anxious.
• D. Have the physician draw the blood.

Correct answer: B

Rationale: In the scenario where a patient is sweating and anxious, it is important to assess for signs of potential syncope (fainting) while proceeding with the blood draw. If the patient does not exhibit signs of fainting, the phlebotomy procedure can be performed safely. Postponing the procedure may not address the patient's anxiety and inconvenience them. Having the physician draw the blood is not necessary if the phlebotomist can handle the situation effectively.

3. A client has fallen asleep in his bed in the hospital. His heart rate is 65 bpm, his muscles are relaxed, and he is difficult to arouse. Which stage of the sleep cycle is this client experiencing?

• A. Stage 1
• B. Stage 2
• C. Stage 3
• D. Stage 4

Correct answer: C

Rationale: The client in this scenario is experiencing stage 3 of the sleep cycle. In stage 3, the individual has moved into deeper stages of sleep, making it difficult to arouse. Characteristics of stage 3 include relaxed muscles, a decrease in vital signs, and being very still. Stage 3 is a phase of non-REM sleep where the client progresses towards REM sleep and vivid dreams. Choices A, B, and D are incorrect. Stage 1 is characterized by light sleep, stage 2 is a slightly deeper sleep with sleep spindles and K-complexes, and stage 4 is the deepest stage of sleep with the slowest brain waves.

4. An adult's blood pressure reads 40/20. You place the patient in a Trendelenberg position before rechecking the blood pressure. What actions will you take to position the patient correctly?

• A. lower the head of the bed and raise the foot of the bed
• B. raise the head of the bed up to about 60 to 75 degrees
• C. raise the head of the bed up to about 75 to 90 degrees
• D. raise the siderails and place the bed in the high position

Correct answer: A

Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.

5. During a class on the aspects of culture, the instructor shares that culture has four basic characteristics. Which statement correctly reflects one of the characteristics of culture?

• A. Static and unchanging
• B. Members sharing similar physical characteristics
• C. Members sharing a common geographic origin and religion
• D. Adapted to specific conditions related to environmental and technical factors

Correct answer: D

Rationale: Culture has four basic characteristics, one of which is that it is adapted to specific conditions related to environmental and technical factors and to the availability of natural resources. The other three characteristics are: (1) learned from birth through the processes of language acquisition and socialization; (2) shared by all members of the cultural group; and (3) dynamic and ever-changing. Culture is not static and unchanging but is dynamic and ever-changing. Members of a culture do not necessarily share similar physical characteristics; that refers to race. Similarly, members of a culture do not necessarily share a common geographic origin and religion; that refers to ethnicity.
