1. In the recent technological innovations, which of the following describe researches that are made to improve and make human life easier?
- A. Pure research
- B. Basic research
- C. Applied research
- D. Experimental research
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.
2. Which type of fatty acid has carbon atoms connected by two or more double bonds?
- A. Saturated fatty acids
- B. Monounsaturated fatty acids
- C. Trans fatty acids
- D. Polyunsaturated fatty acids
Correct answer: D
Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
3. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?
- A. Cyclamate
- B. Acesulfame-K
- C. Saccharin
- D. Aspartame
Correct answer: D
Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.
4. A multivitamin supplement containing folic acid is recommended for all young women because of the number of unintentional pregnancies in women 15 to 24 years old.
- A. Both the statement and the reason are correct and related
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct answer: A
Rationale: Both the statement and the reason are correct and related. A multivitamin with folic acid is recommended for young women due to the high incidence of unplanned pregnancies in this age group.
5. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
