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 performing a gastric lavage for a client who has upper gastrointestinal bleeding. Which of the following actions should the healthcare provider take?

• A. Instill 500 ml of solution through the NG tube.
• B. Insert a large-bore NG tube.
• C. Use a cold irrigation solution.
• D. Instruct the client to lie on their right side.

Correct answer: B

Rationale: During a gastric lavage procedure for upper gastrointestinal bleeding, inserting a large-bore NG tube is essential to effectively remove gastric contents and blood. This tube allows for efficient irrigation and suction, aiding in the removal of harmful substances from the stomach. Instilling a large volume of solution or using a cold irrigation solution can lead to complications such as fluid overload or hypothermia. Instructing the client to lie on their right side is not directly related to the gastric lavage procedure.

3. A healthcare professional is caring for a client who is newly diagnosed with pancreatic cancer and has questions about the disease. To research, the healthcare professional should identify that which of the following electronic databases has the most comprehensive collection of nursing articles?

• A. MEDLINE
• B. CINAHL
• C. ProQuest
• D. Health Source

Correct answer: B

Rationale: CINAHL (Cumulative Index to Nursing and Allied Health Literature) is a comprehensive database that specializes in nursing and allied health literature. It is a valuable resource for healthcare professionals seeking nursing-related articles, making it the most appropriate option for the nurse caring for a client with questions about pancreatic cancer.

4. When providing discharge teaching for a group of clients, a nurse should recommend a referral to a dietitian for which client?

• A. A client who has a prescription for warfarin and states, 'I will need to limit how much spinach I eat.'
• B. A client who has gout and states, 'I can continue to eat anchovies on my pizza.'
• C. A client who has a prescription for spironolactone and states, 'I will reduce my intake of foods that contain potassium.'
• D. A client who has osteoporosis and states, 'I'll plan to take my calcium carbonate with a full glass of water.'

Correct answer: B

Rationale: The correct answer is the client who has gout and states, 'I can continue to eat anchovies on my pizza.' Gout is a condition that requires dietary modifications to manage symptoms. Anchovies are high in purines, which can exacerbate gout symptoms. Therefore, a referral to a dietitian is essential to provide appropriate dietary guidance for a client with gout. Clients on warfarin may need to monitor their vitamin K intake, particularly from foods like spinach. Clients taking spironolactone should be cautious about potassium-rich foods. Clients with osteoporosis should be educated on the proper administration of calcium supplements but do not necessarily need a dietitian referral for this specific statement.

5. When is sterile technique used?

• A. During strict isolation procedures
• B. After terminal disinfection is performed
• C. For invasive procedures
• D. When protective isolation is necessary

Correct answer: C

Rationale: Sterile technique is utilized during invasive procedures to prevent the introduction of pathogens, minimizing the risk of infections. This strict approach ensures that the procedure is performed in a sterile environment, reducing the chances of contamination and subsequent complications.
