Which mineral is a principal component of cell membranes?
- A. phosphorus
- B. magnesium
- C. iron
- D. iodine
Correct Answer: A
Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
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 activities best describe the work of the placenta during pregnancy?
- A. surrounding and cushioning the fetus
- B. combining maternal and fetal blood stores to exchange nutrients
- C. producing hormones that maintain the pregnancy
- D. absorbing vitamins and minerals that can be transferred to the fetus
Correct Answer: C
Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.
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.
Men generally have a higher RDA than women, except during pregnancy and lactation when women's nutritional needs increase significantly.
- A. TRUE
- B. FALSE
Correct Answer: A
Rationale: The statement is TRUE. Men typically require a higher Recommended Dietary Allowance (RDA) than women due to physiological differences. However, during pregnancy and lactation, women's nutritional needs increase significantly to support the growth and development of the baby. Therefore, during these stages, women may require a higher RDA compared to men. This exception is crucial to consider when evaluating nutritional requirements based on gender.
