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. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

3. Examples of patients suffering from impaired awareness include all of the following except:

• A. A semiconscious or overfatigued patient
• B. A disoriented or confused patient
• C. A patient who cannot care for themselves at home
• D. A patient demonstrating symptoms of drug or alcohol withdrawal

Correct answer: C

Rationale: Patients with impaired awareness may exhibit symptoms such as being semiconscious, overfatigued, disoriented, confused, or demonstrating symptoms of drug or alcohol withdrawal. A patient who cannot care for themselves at home does not necessarily indicate impaired awareness, as this could be due to physical limitations or lack of support, rather than a cognitive deficit.

4. Which instrument is used for auscultation?

• A. Percussion hammer
• B. Audiometer
• C. Stethoscope
• D. Sphygmomanometer

Correct answer: C

Rationale: Auscultation involves listening to internal sounds in the body, such as heart and lung sounds. The instrument used for auscultation is a stethoscope, which allows healthcare providers to listen to these sounds. The percussion hammer is used to elicit sounds on the body, the audiometer is used to measure hearing ability, and the sphygmomanometer is used to measure blood pressure. Therefore, the correct answer is 'Stethoscope.'

5. A healthcare professional is preparing to administer an autologous blood product to a client. Which of the following actions should the professional take to identify the client?

• A. Match the client's blood type with the type and cross-match specimens
• B. Confirm the provider's prescription matches the number on the blood component
• C. Ask the client to state their blood type and the date of their last blood donation
• D. Ensure that the client's identification band matches the number on the blood unit

Correct answer: A

Rationale: When preparing to administer an autologous blood product, it is crucial to correctly identify the client to prevent errors. Matching the client's blood type with the type and cross-match specimens ensures that the blood product is intended for the correct recipient. This step helps in verifying the patient's identity and avoiding any transfusion-related complications. Confirming the blood type through type and cross-matching is a standard practice to ensure patient safety during blood transfusions.
