1. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?

• A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
• C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.

Correct answer: A

Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.

2. What is the medical term for a persistent, abnormal distortion of taste?

• A. Anosmia
• B. Dysgeusia
• C. Xerostomia
• D. Hypogeusia

Correct answer: B

Rationale: The correct answer is Dysgeusia, which is a persistent and abnormal distortion of the sense of taste. This condition can be triggered by various factors such as medications or certain diseases. Anosmia, choice A, refers to the loss of the sense of smell, not taste. Xerostomia, choice C, is the medical term for dry mouth, which is not specifically related to a distortion of taste. Hypogeusia, choice D, refers to a reduced ability to taste things, which is not the same as a distortion of the sense of taste.

3. To ensure client safety before starting blood transfusions, the following are needed before the procedure can be done EXCEPT:

• A. take baseline vital signs
• B. warm the blood to room temperature for 30 minutes before administering the transfusion
• C. have two nurses verify client identification, blood type, unit number, and expiration date of blood
• D. get consent signed for blood transfusion

Correct answer: D

Rationale: To ensure client safety before starting blood transfusions, taking baseline vital signs, warming the blood to room temperature, and having two nurses verify client identification, blood type, unit number, and expiration date of blood are crucial steps. Consent for blood transfusion is required but is typically obtained before the procedure. The focus before the procedure should be on confirming the right client, blood product, and ensuring the blood is prepared correctly to minimize risks of transfusion reactions.

4. What condition has been shown to be associated with esophageal dysphagia?

• A. myasthenia gravis
• B. achalasia
• C. Alzheimer's disease
• D. cerebral palsy

Correct answer: B

Rationale: Achalasia is the correct answer. It is a condition characterized by the esophagus having difficulty moving food toward the stomach, resulting in dysphagia (difficulty swallowing). Myasthenia gravis (Choice A) is a neuromuscular disorder that affects skeletal muscles, not the esophagus. Alzheimer's disease (Choice C) primarily affects cognitive function, not the esophagus. Cerebral palsy (Choice D) is a neurological disorder affecting body movement and muscle coordination, unrelated to esophageal dysphagia.

5. During the acute phase of a burn, the priority nursing intervention in caring for this client is:

• A. Prevention of infection
• B. Pain management
• C. Prevention of bleeding
• D. Fluid resuscitation

Correct answer: D

Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.
