An essential nutrient must:
- A. be eaten every day
- B. be obtained by the diet
- C. be water soluble
- D. be eaten at every meal
Correct Answer: B
Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.

The nurse is working with a patient who recently had a stroke. The patient frequently chokes and coughs when eating and is having difficulty feeding herself. What is the best way to ensure adequate nutrition?
- A. to have an aide feed her at each meal
- B. to ask a family member to assist during meals
- C. to provide tube feedings for the patient
- D. to initiate TPN for the patient
Correct Answer: C
Rationale: The best way to ensure adequate nutrition for a stroke patient who frequently chokes and coughs when eating and has difficulty feeding herself is to provide tube feedings. Tube feedings are a safe and effective method to deliver nutrition directly to the stomach or intestines, bypassing the swallowing mechanism, reducing the risk of aspiration. Having an aide feed her each meal (choice A) may not address the underlying issue of swallowing difficulty and aspiration risk. Asking a family member to be present at each meal (choice B) does not provide a definitive solution to the patient's nutritional needs. Placing the patient on total parenteral nutrition (TPN) (choice D) is a more invasive and typically reserved for patients who cannot tolerate enteral feedings or have non-functional gastrointestinal tracts.
Which medical condition is characterized by symptoms such as oral candidiasis, hairy leukoplakia, herpetic ulcerations, Kaposi's sarcoma, xerostomia, and severe periodontal disease?
- A. Acquired Immunodeficiency Syndrome (AIDS)
- B. Acute Leukemia
- C. Anorexia Nervosa
- D. Bulimia
Correct Answer: A
Rationale: Acquired Immunodeficiency Syndrome (AIDS) is known for a variety of oral manifestations such as oral candidiasis, hairy leukoplakia, herpetic ulcerations, Kaposi's sarcoma, xerostomia, and severe periodontal disease. These symptoms are not typically associated with acute leukemia, anorexia nervosa, or bulimia. Acute leukemia usually presents with symptoms like fatigue, frequent infections, and easy bruising. Anorexia nervosa and bulimia are eating disorders, thus their primary symptoms are primarily associated with eating habits and body weight, not oral health.
What does oliguria lead to in patients with acute kidney injury?
- A. Hypophosphatemia and overgrowth of bone tissue
- B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
- C. Sodium retention and elevated levels of potassium
- D. Edema due to increased urine production
Correct Answer: C
Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.
What gastrointestinal side effects are associated with antisecretory drugs such as proton pump inhibitors?
- A. Nausea and vomiting
- B. Gastroparesis
- C. Dumping syndrome
- D. Flatulence
Correct Answer: A
Rationale: Proton pump inhibitors (PPIs) are a type of antisecretory drug that can cause nausea and vomiting by altering stomach acid production. These are common side effects associated with PPIs. Gastroparesis (B) is a condition that affects the stomach muscles and prevents proper stomach emptying; it is not a side effect of PPIs. Dumping syndrome (C) is a group of symptoms that can occur after having part of your stomach removed and is not a side effect of PPIs. While some people might experience flatulence (D) when taking PPIs, it is not as commonly associated with these drugs as the effects of nausea and vomiting.
Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?
- A. fiber and carbohydrates
- B. fatty acids and protein
- C. probiotics
- D. antioxidants and phytochemicals
Correct Answer: D
Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.
