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. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.

3. A client has global aphasia affecting both receptive and expressive language abilities. Which intervention should NOT be included in the client's care plan?

• A. Speak to the client at a slower rate.
• B. Assist the client in using flash cards with pictures.
• C. Speak to the client in a loud voice.
• D. Give instructions one step at a time.

Correct answer: C

Rationale: Individuals with global aphasia have difficulty understanding and expressing language. Speaking loudly may not improve comprehension and can be perceived as aggressive. Therefore, it is important not to speak loudly to a client with global aphasia. Speaking at a slower rate, using visual aids like flash cards, and breaking down instructions into simple steps can facilitate communication and understanding for the client.

4. Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?

• A. Opening the patient’s window to the outside environment
• B. Turning on the patient’s room ventilator
• C. Opening the door of the patient’s room leading into the hospital corridor
• D. Failing to wear gloves when administering a bed bath

Correct answer: D

Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.

5. Which of the following patients is at greatest risk for developing pressure ulcers?

• A. An alert chronic arthritic patient treated with steroids and aspirin
• B. An 88-year-old incontinent patient with gastric cancer who is confined to bed at home
• C. An apathetic 63-year-old COPD patient receiving nasal oxygen via cannula
• D. A confused 78-year-old patient with congestive heart failure (CHF) who requires assistance to get out of bed

Correct answer: B

Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.
