1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?
- A. The body can produce sufficient amounts of vitamin D from sunlight.
- B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
- C. Sunscreen blocks the formation of vitamin D3.
- D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.
Correct answer: C
Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.
2. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?
- A. The DRIs replace the older recommended daily allowances
- B. Current DRIs attempt to estimate required nutrients to improve long-term health
- C. DRIs specifically address individuals whose requirements are affected by a disease state
- D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients
Correct answer: C
Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.
3. Mang Caloy is scheduled to have a hemorrhoidectomy, after the operation, you would expect that the client’s position post operatively will be:
- A. Knee chest position
- B. Side lying position
- C. Sims position
- D. Genopectoral position
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
4. What is a common symptom of vitamin D deficiency?
- A. Hair loss
- B. Night blindness
- C. Bone pain
- D. Rashes
Correct answer: C
Rationale: The correct answer is C: Bone pain. Vitamin D deficiency often leads to bone pain and weakness as it plays a crucial role in maintaining bone health by aiding in the absorption of calcium. Hair loss (choice A) is not a common symptom of vitamin D deficiency. Night blindness (choice B) is typically associated with vitamin A deficiency, not vitamin D deficiency. Rashes (choice D) are not a common symptom of vitamin D deficiency.
5. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:
- A. 140 mm Hg and 90 mm Hg, respectively
- B. 150 mm Hg and 80 mm Hg, respectively
- C. 160 mm Hg and 110 mm Hg, respectively
- D. 180 mm Hg and 120 mm Hg, respectively
Correct answer: A
Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
