1. Which term is used to describe populations located in lower income, inner city, and rural areas with few supermarkets but numerous small stores stocking limited nutritious food items?
- A. Food fad
- B. Food insecurity
- C. Food desert
- D. Food patterns
Correct answer: C
Rationale: A food desert refers to areas with limited access to affordable and nutritious food, often found in lower-income urban and rural areas.
2. Maria’s statement “Bow down before me! I am the holy mother of Christ! I am the blessed Virgin Mary!†is an example of:
- A. Delusion of grandeur
- B. Visual Hallucination
- C. Religious delusion
- D. Auditory Hallcucination
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?
- A. Longer exposure leads to an increased risk of demineralization
- B. Longer exposure increases the opportunity for remineralization
- C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
- D. The critical pH at which enamel decalcification occurs is 5.5 or less
Correct answer: B
Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
4. Each statement is true of proteins, except one. Which is the exception?
- A. Proteins are composed of building blocks called amino acids
- B. The classification of the 20 common amino acids is based on the properties of their side chains
- C. The general structure of an amino acid varies considerably
- D. Amino acids polymerize to form long chains called polypeptides
Correct answer: B
Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.
5. In taking the client’s blood pressure, the nurse should position the client’s arm:
- A. At the level of the heart
- B. Slightly above the level of the heart
- C. At the 5th intercostals space midclavicular line
- D. Below the level of the heart
Correct answer: A
Rationale: Proper patient positioning is essential for maximizing lung expansion and promoting the drainage of secretions. Postural drainage techniques rely on gravity to help clear different lung segments, which is critical in preventing complications such as atelectasis or pneumonia in immobilized patients.
