1. Electrolytes create _____, which is caused by water following electrolytes within or between cells.
- A. energy
- B. active transport
- C. passive diffusion
- D. osmotic pressure
Correct answer: D
Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.
2. You notice that Miss Kate, a bread vendor, receives and changes money, then holds the bread without washing her hands. As a nurse, what should you say to Miss Kate?
- A. Miss, don't touch the bread, I'll be the one to pick it up.
- B. Miss, please wash your hands before you pick up the bread.
- C. Miss, use a pick-up forceps when picking up the bread.
- D. Miss, your hands are dirty, I guess I'll try another bread shop.
Correct answer: B
Rationale: The correct answer is B, as it emphasizes the importance of hygiene in food handling, which is crucial to prevent the spread of germs and diseases. The other options do not address the root of the issue, which is the unhygienic handling of food. Option A avoids direct confrontation but does not educate the vendor on proper hygiene. Option C, although it suggests a hygienic method, may not be practical or available in all situations. Option D is an avoidance strategy rather than a way to address the problem.
3. 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. Polyunsaturated fatty acids
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.
4. Which meal should be removed for a client taking warfarin?
- A. Oriental cabbage salad with chicken
- B. Beef enchilada, rice, and beans
- C. Ham and cheese sandwich
- D. Macaroni salad and grapefruit slices
Correct answer: C
Rationale: The correct meal to remove for a client taking warfarin is the 'Ham and cheese sandwich.' Ham is high in vitamin K, which can interfere with the effectiveness of warfarin, a medication that works by decreasing the clotting ability of the blood. Vitamin K can counteract the effects of warfarin by promoting blood clotting. Choices A, B, and D do not contain high amounts of vitamin K and are therefore safer options for individuals taking warfarin.
5. Which physiologic effect should the nurse expect in a client addicted to hallucinogens?
- A. Dilated pupils
- B. Constricted pupils
- C. Bradycardia
- D. Bradypnea
Correct answer: B
Rationale: Clients addicted to hallucinogens often exhibit constricted pupils due to the effects of the drug on the sympathetic nervous system. This sympathetic stimulation causes the pupils to constrict rather than dilate. Choices A, C, and D are incorrect. Dilated pupils are more commonly associated with stimulant use, while bradycardia (slow heart rate) and bradypnea (slow breathing) are not typical effects of hallucinogens.
