What is the function of the gallbladder?
- A. to store bile
- B. to produce bile
- C. to digest bile
- D. to modify bile to a liquid form
Correct Answer: A
Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.

What type of drug would most likely be given to a patient following a myocardial infarction?
- A. antiemetic
- B. anticoagulant
- C. anticonvulsant
- D. antibiotic
Correct Answer: B
Rationale: Anticoagulants are the most suitable choice for a patient following a myocardial infarction. These medications are essential in preventing further blood clots from forming in the arteries, reducing the risk of complications such as strokes or recurrent heart attacks. Antiemetics are used to control nausea and vomiting, not directly related to myocardial infarction. Anticonvulsants are used to manage seizures, not typically indicated after a heart attack. Antibiotics are prescribed to treat bacterial infections, not routinely given after a myocardial infarction.
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.
During the later stages of chronic kidney disease, what is the recommended protein intake in grams per kilogram of body weight per day?
- A. 0.6 to 0.75
- B. 1.2 to 1.55
- C. 1.0 to 1.2
- D. 0.8 to 1.0
Correct Answer: A
Rationale: In the later stages of chronic kidney disease, the recommended protein intake is typically restricted to 0.6 to 0.75 grams per kilogram of body weight per day. This lower protein intake helps reduce the workload on the kidneys, as excessive protein can be challenging for the kidneys to process. Choice B (1.2 to 1.55) is incorrect as it suggests a higher protein intake, which is not recommended for individuals with advanced kidney disease. Choices C (1.0 to 1.2) and D (0.8 to 1.0) also advocate for protein intakes higher than what is typically advised for individuals in later stages of chronic kidney disease.
Clients may benefit from slightly higher fat intakes than are normally recommended if they have:
- A. congestive heart failure
- B. cerebrovascular accident
- C. peripheral vascular disease
- D. chronic obstructive pulmonary disease
Correct Answer: D
Rationale: In chronic obstructive pulmonary disease (COPD), higher fat intake can be beneficial because it provides more calories with less respiratory burden compared to carbohydrates. Choices A, B, and C are incorrect because congestive heart failure, cerebrovascular accident, and peripheral vascular disease do not specifically benefit from higher fat intakes as in COPD.
Each statement is true of swallowing and processing food, except one. Which is the exception?
- A. The swallowing reflex moves a bolus into the esophagus
- B. A bolus is a mass of food
- C. The bolus is transported to the stomach by osmosis and gravity
- D. The bolus penetrates the diaphragm through the esophageal hiatus
Correct Answer: C
Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.
