1. Which food item interferes with the effectiveness of warfarin?

• A. Cauliflower
• B. Zucchini
• C. Green beans
• D. Broccoli

Correct answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.

2. What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?

• A. conserving calcium stores
• B. contracting the uterus
• C. protecting against future hypertension
• D. speeding the resumption of ovulation

Correct answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

3. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

• A. Spinach
• B. Cantaloupe
• C. Chicken
• D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

4. Symptoms of irritable bowel syndrome are most likely associated with disturbed defecation, bloating, and _____.

• A. rectal bleeding
• B. abdominal pain
• C. rectal fissures
• D. esophageal paralysis

Correct answer: B

Rationale: Abdominal pain is a common symptom of irritable bowel syndrome (IBS), along with bloating and changes in bowel habits. Rectal bleeding (choice A) is more commonly associated with conditions like inflammatory bowel disease or colorectal cancer. Rectal fissures (choice C) may cause rectal bleeding but are not typically considered a core symptom of IBS. Esophageal paralysis (choice D) is unrelated to the symptoms of IBS, which primarily affect the lower gastrointestinal tract.

5. 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.
