Nutrition Final Exam
1. What is one function of water in the human body?
- A. Water provides calories for energy.
- B. Water helps transport nutrients and waste products.
- C. Water acts as a solvent for many biological reactions.
- D. Water maintains body temperature.
Correct answer: B
Rationale: The correct answer is B: Water helps transport nutrients and waste products. Water plays a crucial role in the body by aiding in the transportation of essential nutrients to cells and removing waste products. While water is essential for various metabolic processes, it does not provide calories for energy (choice A). Although water can act as a solvent for biological reactions (choice C), its primary function is not as a solvent. Additionally, while water does help in regulating body temperature to some extent, its main role is not to maintain body temperature (choice D).
2. The school nurse is presenting a class to a group of students about common overuse disorders. Which disorder would the school nurse include?
- A. Dislocated radial head
- B. Transient synovitis of the hip
- C. Osgood-Schlatter disease
- D. Scoliosis
Correct answer: C
Rationale: Osgood-Schlatter disease is a common overuse injury that specifically affects the knee. It is characterized by inflammation of the patellar ligament at the tibial tuberosity due to repetitive strain on the growth plate during activities such as running and jumping. Dislocated radial head (Choice A) is not an overuse disorder but rather an injury usually seen in young children. Transient synovitis of the hip (Choice B) is an acute hip condition and not typically classified as an overuse disorder. Scoliosis (Choice D) is a condition characterized by an abnormal lateral curvature of the spine and is not considered an overuse disorder.
3. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?
- A. Double the birth weight
- B. Triple the birth weight
- C. Gain 6 ounces each week
- D. Add 2 pounds each month
Correct answer: A
Rationale: The correct answer is A: 'Double the birth weight.' Infants typically double their birth weight by 6 months of age. This is a common milestone in healthy infant growth and development. Choice B is incorrect because tripling the birth weight would be excessive and not in line with normal growth patterns. Choice C, 'Gain 6 ounces each week,' is not accurate as infant growth is not linear each week. Choice D, 'Add 2 pounds each month,' is also incorrect as this rate of growth would be too rapid and unrealistic for healthy infant development.
4. When providing hygiene for an older-adult patient, why does the nurse closely assess the skin?
- A. Outer skin layer becomes less resilient.
- B. Less frequent bathing may be required.
- C. Skin becomes more subject to bruising.
- D. Sweat glands become less active.
Correct answer: B
Rationale: The correct answer is B: 'Less frequent bathing may be required.' In older adults, daily bathing or using hot water and harsh soap can lead to excessively dry skin. Therefore, the nurse closely assesses the skin to determine if less frequent bathing is necessary to prevent skin dryness and maintain skin integrity. Choice A is incorrect because the outer skin layer does not become less resilient with age. Choice C is incorrect as aging skin is actually more prone to bruising due to thinning of the skin. Choice D is incorrect because sweat gland activity generally decreases with age, leading to reduced skin moisture rather than increased activity.
5. A client who is postoperative is verbalizing pain as a 2 on a pain scale of 0 to 10. Which of the following statements should the nurse identify as an indication that the client understands the preoperative teaching she received about pain management?
- A. ''I think I should take my pain medication more often since it is not controlling my pain.''
- B. ''Breathing faster will help me keep my mind off of the pain.''
- C. ''It might help me to listen to music while I'm lying in bed.''
- D. ''I don't want to walk today because I have some pain.''
Correct answer: C
Rationale: The correct answer is C because listening to music is an effective nonpharmacological intervention for managing mild pain. Choice A is incorrect as increasing the frequency of pain medication without consulting healthcare providers can lead to adverse effects. Choice B is incorrect as distracting techniques like breathing faster may not address the pain effectively. Choice D is incorrect as avoidance of physical activity due to pain can hinder postoperative recovery.
