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. Parenteral penicillin can be administered as an:

• A. IM injection or an IV solution
• B. IV or an intradermal injection
• C. Intradermal or subcutaneous injection
• D. IM or a subcutaneous injection

Correct answer: A

Rationale: Penicillin can be administered intramuscularly or intravenously.

3. Which of the following substances increase the amount of urine produced?

• A. Caffeine-containing drinks, such as coffee and cola
• B. Beets
• C. Urinary analgesics
• D. Kaolin with pectin (Kaopectate)

Correct answer: A

Rationale: Caffeine is a diuretic, which means it increases urine production by promoting the excretion of water from the body through the kidneys. Therefore, substances like caffeine-containing drinks, such as coffee and cola, can lead to an increase in the amount of urine produced.

4. After 5 days of diuretic therapy with 20mg of furosemide (Lasix) daily, a patient begins to exhibit fatigue, muscle cramping, and muscle weakness. These symptoms probably indicate that the patient is experiencing:

• A. Hypokalemia
• B. Hyperkalemia
• C. Anorexia
• D. Dysphagia

Correct answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

5. A group of clients are being educated about influenza. Which of the following client statements indicates an understanding of the teaching?

• A. ''I should wash my hands after blowing my nose to prevent spreading the virus.''
• B. ''I need to avoid drinking fluids if I develop symptoms.''
• C. ''I need a flu shot every 2 years because of the different flu strains.''
• D. ''I should cover my mouth with my hand when I sneeze.''

Correct answer: A

Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.
