1. A dental hygienist finds several new carious lesions in a patient with chronic obstructive respiratory disease (COPD). While conducting the medical and dental histories, the dental hygienist is most likely to find an increased use of which of the following?

• A. Protein
• B. Cough drops
• C. Fluoride
• D. Xylitol

Correct answer: B

Rationale: The correct answer is B: Cough drops. Patients with COPD often use cough drops to manage their symptoms, which can lead to an increase in carious lesions due to their sugar content. Choices A, C, and D are incorrect as protein, fluoride, and xylitol are not typically associated with an increased risk of carious lesions in patients with COPD.

2. Instruction on health promotion regarding urinary elimination is important. Which would you include?

• A. Hold urine as long as possible before emptying the bladder to strengthen the sphincter muscles
• B. If a burning sensation is experienced while voiding, drink water
• C. After urination, wipe from the anal area towards the pubis
• D. Tell the client to empty the bladder at each voiding

Correct answer: D

Rationale: The correct answer is to instruct the client to empty the bladder at each voiding. This is essential to prevent urinary retention and reduce the risk of urinary tract infections. Choice A is incorrect because holding urine for prolonged periods can lead to urinary retention and increase the risk of infections. Choice B is incorrect as pineapple juice can exacerbate a burning sensation due to its acidity; the correct approach is to drink water to dilute the urine. Choice C is incorrect as wiping from the anal area towards the pubis can introduce bacteria into the urinary tract, potentially causing infections.

3. How is an ear infection that persists for less than 14 days classified?

• A. Mastoiditis
• B. Chronic Ear Infection
• C. Acute Ear Infection
• D. Otitis Media

Correct answer: C

Rationale: Acute Ear Infection is the correct answer because it typically refers to an infection that is short-lived and often severe, typically lasting less than 14 days. Chronic Ear Infection (Choice B) is incorrect as it refers to an ear infection that lasts for a long time or recurs often, typically more than three months. Mastoiditis (Choice A) is a complication of a middle ear infection and not an ear infection itself. Otitis Media (Choice D) is a general term for inflammation or infection in the middle ear, which can be either acute or chronic, so it's not specific enough to be the correct answer. Understanding the duration and severity of symptoms can help in identifying the type of ear infection, facilitating appropriate treatment and prevention of complications.

4. A nurse is educating a group of older adults in a community center on weight management using the BMI scale. Using the client's height and weight to calculate BMI, which of the following clients has a healthy BMI?

• A. A client with a weight of 128 lb and height of 70 inches
• B. A client with a weight of 150 lb and height of 68 inches
• C. A client with a weight of 200 lb and height of 72 inches
• D. A client with a weight of 133 lb and height of 60 inches

Correct answer: A

Rationale: To determine a healthy BMI, we need to calculate it using the formula: BMI = weight (lbs) / height^2 (inches) x 703. For choice A, BMI = 128 / (70 x 70) x 703 = 18.38, which falls within the healthy BMI range of 18.5-24.9. Therefore, choice A is correct. Choices B, C, and D have BMIs of 22.8, 27.1, and 26.1, respectively, which are outside the healthy range. Thus, choices B, C, and D are incorrect.

5. With which of the following should fluoride supplements never be taken?

• A. Water
• B. Juice
• C. Milk
• D. Soda

Correct answer: C

Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.
