1. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

2. A healthcare provider is caring for a client following a thoracentesis. Which of the following manifestations should the healthcare provider NOT recognize as risks for complications?

• A. Dyspnea
• B. Localized bloody drainage on the dressing
• C. Fever
• D. Hypotension

Correct answer: B

Rationale: After a thoracentesis, some expected complications include dyspnea, fever, and hypotension. Localized bloody drainage on the dressing is a common and expected finding post-thoracentesis due to the procedure's nature of puncturing the chest wall. Therefore, the healthcare provider should not consider this finding as a risk for complications.

3. When is additional Vitamin C not required?

• A. Infancy
• B. Young adulthood
• C. Childhood
• D. Pregnancy

Correct answer: B

Rationale: Vitamin C requirements are increased during infancy, childhood, and pregnancy due to growth and development. However, during young adulthood, the body generally requires a consistent amount of Vitamin C as it is not undergoing rapid growth or physiological changes that necessitate an increase in Vitamin C intake.

4. What is the appropriate route of administration for insulin?

• A. Intramuscular
• B. Intradermal
• C. Subcutaneous
• D. Intravenous

Correct answer: C

Rationale: The appropriate route of administration for insulin is subcutaneous. Subcutaneous injections are commonly used for insulin administration due to the slower absorption rate compared to intramuscular or intravenous routes. This slower absorption rate allows for better control of blood glucose levels. Intramuscular administration is not ideal for insulin as it can lead to rapid absorption and fluctuations in blood sugar levels. Intradermal injections are shallow and used for skin testing rather than insulin administration. Intravenous administration of insulin is not recommended due to the rapid and unpredictable effects it can have on blood glucose levels.

5. Which of the following is a sign or symptom of a hemolytic reaction to a blood transfusion?

• A. Hemoglobinuria
• B. Chest pain
• C. Urticaria
• D. Distended neck veins

Correct answer: A

Rationale: Hemoglobinuria is a characteristic sign of a hemolytic reaction to a blood transfusion. Hemolytic reactions can lead to the destruction of red blood cells, causing the release of hemoglobin into the urine, which presents as hemoglobinuria. Chest pain, urticaria, and distended neck veins are not specific signs of a hemolytic reaction and may be associated with other conditions or reactions.
