1. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
2. What is the first step in decontamination?
- A. Immediately applying a chemical decontamination foam to the area of contamination
- B. Thoroughly washing and rinsing the patient with soap and water
- C. Immediately applying personal protective equipment
- D. Removing the patient's clothing and jewelry, then rinsing the patient with water
Correct answer: D
Rationale: The correct first step in decontamination is to remove the patient's clothing and jewelry to prevent further exposure and then rinse the patient with water. This helps to eliminate any contaminants on the patient's body. Choice A is incorrect because applying a chemical decontamination foam should come after removing clothing. Choice B is incorrect as washing and rinsing the patient should follow the removal of clothing. Choice C is incorrect as personal protective equipment should be worn by the individual performing the decontamination, not applied to the patient.
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. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: A
Rationale: Both statements are indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.
5. 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.
