1. A condition that is conducive to the development of dental caries is said to be _____.

• A. periodontal
• B. cariogenic
• C. gingival
• D. bacteriophilic

Correct answer: B

Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.

2. Select all that apply. Which of the following are true about protein digestion?

• A. the end products of protein digestion are amino acids
• B. protein/polypeptides are digested in the large intestine by trypsin
• C. A, D
• D. protein/polypeptides are digested in the stomach by pepsin

Correct answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.

3. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

• A. Measure the tube length.
• B. Obtain an abdominal x-ray.
• C. Flush the tube with 20 mL of water.
• D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

4. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:

• A. they must be supplied by the diet
• B. they can be produced by a process called dehydrogenation
• C. they are anti-inflammatory
• D. they are all polyunsaturated fatty acids

Correct answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.

5. Which physiologic effect should the nurse expect in a client addicted to hallucinogens?

• A. Dilated pupils
• B. Constricted pupils
• C. Bradycardia
• D. Bradypnea

Correct answer: B

Rationale: Clients addicted to hallucinogens often exhibit constricted pupils due to the effects of the drug on the sympathetic nervous system. This sympathetic stimulation causes the pupils to constrict rather than dilate. Choices A, C, and D are incorrect. Dilated pupils are more commonly associated with stimulant use, while bradycardia (slow heart rate) and bradypnea (slow breathing) are not typical effects of hallucinogens.
