1. Intrinsic factor from the stomach is needed for the absorption of which vitamin?
- A. vitamin B12
- B. folate
- C. niacin
- D. vitamin B6
Correct answer: A
Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.
2. A healthcare professional is preparing to remove a client’s clogged NG tube prior to re-inserting a new tube. Which of the following actions should the healthcare professional take first?
- A. Assist the client in blowing their nose.
- B. Ask the client to take a deep breath and hold it.
- C. Pinch the proximal end of the tube.
- D. Disconnect the tube from the suction source.
Correct answer: D
Rationale: Correct Answer: Disconnecting the tube from the suction source is the first step in safely removing a clogged NG tube. This action helps prevent any suction-related complications and ensures a smooth transition when removing the tube. Choice A, assisting the client to blow their nose, is not necessary in this situation. Choice B, asking the client to take a deep breath and hold it, is unrelated to the process of removing a clogged NG tube. Choice C, pinching the proximal end of the tube, should only be done after disconnecting the tube from the suction source to prevent the contents from leaking.
3. A nurse is caring for a client who is receiving parenteral nutrition. Which of the following findings indicates the therapy is effective?
- A. Client has soft, formed bowel movements.
- B. Client’s mucous membranes are pink.
- C. Client reports ability to complete ADLs.
- D. Client’s blood glucose level is within the expected reference range.
Correct answer: D
Rationale: The correct answer is D because having a blood glucose level within the expected reference range indicates that parenteral nutrition is effectively meeting the client's nutritional needs. Choices A, B, and C are incorrect because soft, formed bowel movements, pink mucous membranes, and the ability to complete activities of daily living do not directly reflect the effectiveness of parenteral nutrition therapy.
4. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:
- A. First degree burn C. Third degree burn
- B. Second degree burn D. Partial thickness burn
- C.
- D.
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.
5. With which of the following should fluoride supplements never be taken?
- A. Water
- B. Juice
- C. Milk
- D. Soda
Correct answer: C: Milk
Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.
