1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. An occupational health nurse works at a manufacturing plant where there is potential exposure to inhaled dust. Which action, if recommended by the nurse, will be most helpful in reducing the incidence of lung disease?

• A. Treat workers with pulmonary fibrosis.
• B. Teach about symptoms of lung disease.
• C. Require the use of protective equipment.
• D. Monitor workers for coughing and wheezing.

Correct answer: C

Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.

3. Elderly patients are more prone to dehydration than younger people because the elderly ___________.

• A. drink more coffee and tea
• B. have more stomach mucus production
• C. have more saliva
• D. have less sense of thirst

Correct answer: D

Rationale: Elderly patients are prone to dehydration because they have a lower and diminished sense of thirst. This reduced sensation of thirst makes them less likely to drink an adequate amount of fluids, leading to dehydration. While it is true that elderly individuals may also have changes such as decreased stomach mucus production and saliva production, these factors do not directly contribute to dehydration. Drinking more coffee and tea, as mentioned in choice A, is not a consistent behavior among all elderly individuals and is not a primary reason for their increased risk of dehydration.

4. Which of the following reasons would be legal when considering a patient's medical record?

• A. Allowing a patient's brother to view her chart to find out her birthdate and address so that he can mail her a card
• B. Not allowing a patient to view her own chart because the physician feels this information would be detrimental to her wellbeing
• C. Not allowing a patient to view her chart because she is behind on her payments
• D. All of the above are legal

Correct answer: B

Rationale: The correct answer is not allowing a patient to view her own chart because the physician feels this information would be detrimental to her wellbeing. Physicians have a duty to withhold certain health information from patients if disclosing it could potentially harm the patient. In situations where revealing certain information may have a significantly negative impact on the patient's mental or physical health, healthcare providers have the legal right to withhold that information. Allowing a patient's brother to view her chart for non-medical reasons like sending a card is not a valid legal reason for disclosing patient information. Similarly, refusing access based on financial reasons is not a legal ground for restricting access to a patient's medical record as patient care should not be influenced by financial matters.

5. A healthcare professional is preparing to draw a blood specimen from an adult client's central line. All of the following actions for this procedure are correct EXCEPT:

• A. Disconnect the current infusion
• B. Clean the cap with alcohol and attach a 5 cc syringe
• C. Draw 5 cc of a blood sample to discard
• D. Flush with saline after the sample

Correct answer: B

Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.
