1. What primarily determines the Dietary Reference Intake (DRI) for protein?
- A. Intake of fatty acids
- B. Gender
- C. Height
- D. Body weight
Correct answer: D
Rationale: The Dietary Reference Intake (DRI) for protein is primarily determined by an individual's body weight. This is because the body's protein requirement is proportionate to its size, which is generally reflected in the body weight. Therefore, choice D is correct. Choices A, B, and C are incorrect: While factors such as fatty acid intake, gender, and height can influence an individual's overall nutritional needs, they do not directly determine the DRI for protein.
2. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?
- A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
- B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
- C. Poor nutrition has an adverse effect on the periodontium
- D. Chewing soft, spongy foods stimulates salivary flow
Correct answer: D
Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.
3. Where should a nurse auscultate the apex beat?
- A. At the fifth intercostal space, along the midclavicular line
- B. At the mid-sternum
- C. 2 inches to the left of the lower end of the sternum
- D. 1 inch to the left of the xiphoid process
Correct answer: A
Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.
4. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: D
Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.
5. Why is bleeding in the leg of a pregnant woman considered as an emergency?
- A. Blood volume is greater in pregnant woman; therefore, blood loss is increased
- B. There is an increase blood pressure during pregnancy increasing the likelihood of hemorrhage
- C. Pregnant woman are anemic, all forms of blood loss should be considered as an emergency especially if it is in the
- D. The pressure of the gravid uterus will exert additional force thus, increasing the blood loss in the lower extremities
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.
