1. What is the primary nutritional deficiency of concern for a strict vegetarian?
- A. vitamin C
- B. vitamin B12
- C. vitamin E
- D. magnesium
Correct answer: B
Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.
2. The nurse is observing a client self-administer two crushable medications through their G-tube. Which of the following would indicate a need for further instruction?
- A. The client flushes the G-tube before administering the medications, in between the two medications, and after the medications.
- B. The client states they will remain in the Semi-Fowler's position for 30 minutes following the administration of the medications.
- C. The client mixes each medication separately in warm water.
- D. The client mixes their medications with their tube-feeding formula.
Correct answer: D
Rationale: The correct answer is that the client mixes their medications with their tube-feeding formula. Medications should not be mixed with tube-feeding formula or other medications as it may alter their effectiveness. The G-tube should be flushed before, between, and after the medications to prevent clogging and ensure proper administration. The client should remain in the Semi-Fowler's position for at least 30 minutes after medication administration to prevent reflux. Choice B is correct as it aligns with the proper post-administration positioning. Choices A and C are incorrect as flushing the G-tube before, between, and after medications, and mixing each medication separately in warm water are appropriate procedures that do not indicate a need for further instruction.
3. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?
- A. 6
- B. 8
- C. 12
- D. 16
Correct answer: C
Rationale: An 18-month-old child should have approximately 12 teeth. In general, children begin dentition around 6 months of age. During the first 2 years of life, a quick guide to the number of teeth a child should have is as follows: Subtract the number 6 from the number of months in the age of the child. In this example, the child is 18 months old, so the formula is 18 - 6 = 12. The correct answer is 12. Choice A (6) is incorrect as it does not consider the child's age. Choices B (8) and D (16) are incorrect as they do not align with the dental development timeline and the specific age of the child in question.
4. What effect can medication bound to protein have?
- A. reduced drug availability
- B. limited distribution of the drug to receptor sites
- C. less availability to produce desired medicinal effects
- D. decreased metabolism of the drug by the liver
Correct answer: C
Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.
5. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?
- A. The client can read from 20' what a person with normal vision can read at 30'.
- B. The client can read from 30' what a person with normal vision can read at 20'.
- C. The client can read the entire chart from 30'.
- D. The client can read the chart from 20' with the left eye and from 30' with the right eye.
Correct answer: A
Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.
