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. What is the best description of resonance?

• A. Sounds created by air-filled structures
• B. Short, high-pitched, and thudding
• C. Moderately loud with a musical quality
• D. Drum-like

Correct answer: A

Rationale: Resonance refers to the quality of sound produced by vibrations that are reinforced by other vibrations of the same frequency. In the context of the human body, resonance is often associated with sounds produced by air-filled structures like the lungs, vocal cords, and resonating cavities. Therefore, the best description of resonance from the given options is 'Sounds created by air-filled structures.' This choice aligns with the concept of resonance as it relates to sound production in the human body. Choices B, C, and D are incorrect as they do not specifically relate to the concept of resonance or its association with air-filled structures.

3. A client is recovering from an acute myocardial infarction that occurred 3 days ago. Which of the following instructions should the nurse include in the care plan?

• A. Perform an ECG every 12 hours.
• B. Place the client in a supine position while resting.
• C. Draw a troponin level every 4 hours.
• D. Obtain a cardiac rehabilitation consultation.

Correct answer: D

Rationale: After an acute myocardial infarction, cardiac rehabilitation is crucial for the client's recovery. It helps improve the client's overall cardiovascular health, reduces the risk of future cardiac events, and promotes a healthy lifestyle. The other options do not directly address the importance of cardiac rehabilitation in the client's recovery process.

4. A client experiencing dyspnea will receive continuous oxygen. Which oxygen device should be used to deliver a precise amount of oxygen?

• A. Non-rebreather mask
• B. Venturi mask
• C. Nasal cannula
• D. Simple face mask

Correct answer: B

Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.

5. A healthcare professional is receiving a telephone prescription from a provider for a client who requires additional medication for pain control. Which of the following entries should the healthcare professional make in the medical record?

• A. Morphine 3 mg Subcutaneous every 4 hr. PRN for pain.
• B. Morphine 3 mg Subcutaneous
• C. Morphine 3.0 mg subcutaneously every 4 hr. PRN for pain.
• D. Morphine 3 mg Subcutaneous q 4 hr. PRN for pain.

Correct answer: D

Rationale: The correct entry for documenting the prescription for morphine is 'Morphine 3 mg Subcutaneous'. This entry accurately specifies the medication, dosage, route of administration, and frequency as prescribed by the provider. Options A, C, and D contain minor errors such as missing units of measurement or incorrect abbreviations, which could lead to misinterpretation or potential medication errors. Therefore, the most appropriate and accurate choice is 'Morphine 3 mg Subcutaneous'.
