1. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?

• A. Longer exposure leads to an increased risk of demineralization
• B. Longer exposure increases the opportunity for remineralization
• C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
• D. The critical pH at which enamel decalcification occurs is 5.5 or less

Correct answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.

2. 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.

3. A client receiving chemotherapy treatments tells the nurse, 'I feel so nauseated after my treatments.' Which of the following instructions should the nurse provide the client?

• A. Eat common foods that are served cold.
• B. Sip fluids slowly throughout the day.
• C. Sit up for 1 hr after eating meals.
• D. All of the Above

Correct answer: D

Rationale: The correct answer is D, 'All of the Above.' Common foods served cold, sipping fluids slowly throughout the day, and sitting up for 1 hr after eating meals can help manage nausea associated with chemotherapy. Eating common foods served cold can be easier on the stomach, sipping fluids slowly can prevent overwhelming the digestive system, and sitting up after meals can aid digestion. Choices A, B, and C all contribute to alleviating nausea and are appropriate instructions for the client.

4. Considering the statement that communication is most effective when barriers are first removed, which of the following is recognized as an inhibiting factor in communication?

• A. Avoidance of universally accepted abbreviations
• B. Usage of incorrect grammar
• C. Poor handwriting
• D. Advanced age of the client

Correct answer: D

Rationale: The correct answer is 'D: Advanced age of the client.' Age can be a significant obstacle in communication due to factors such as hearing loss, cognitive decline, or memory issues, which all can hamper effective communication. Choices A, B, and C, while they may present challenges in communication, are not directly related to age and its influence on communication, making them incorrect. The issues presented by not using universally accepted abbreviations, incorrect grammar, and poor handwriting can be resolved through clarification, education, or the use of alternative communication methods, unlike the difficulties that can arise from advanced age.

5. How many words does a typical 12-month-old infant use?

• A. About 12 words
• B. Twenty or more words
• C. About 50 words
• D. Two, plus 'mama' and 'papa'

Correct answer: D

Rationale: A typical 12-month-old infant typically uses very few words, with 'mama' and 'papa' being common early words. At this age, most infants are still in the early stages of language development, and their vocabulary is limited. Choices A, B, and C suggest higher word counts which are not typical for infants at this age.
