Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?
- A. 0.9% sodium chloride
- B. 5% dextrose in water solution
- C. Sterile water
- D. Heparin sodium
Correct Answer: A
Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.

A nurse in a day-care setting is planning play activities for 2- and 3-year-old children. Which toys are most appropriate for these activities?
- A. Finger paints and card games
- B. Blocks and push-pull toys
- C. Videos and cutting-and-pasting toys
- D. Simple board games and puzzles
Correct Answer: B
Rationale: The most appropriate toys for 2- and 3-year-old children in a day-care setting are blocks and push-pull toys. Toddlers enjoy objects of different textures like clay, sand, finger paints, and bubbles, as well as push-pull toys, large balls, and sand and water play. They also like activities such as blocks, painting, coloring with large crayons, large puzzles, and playing with trucks or dolls. Finger paints and card games may be more suitable for older children. Videos and cutting-and-pasting toys are generally more appropriate for preschoolers. Blocks and push-pull toys are beneficial for young children as they help in developing fine motor skills, hand-eye coordination, spatial awareness, and creativity. These toys also encourage imaginative play and problem-solving, making them ideal choices for toddlers.
When educating an obese client about nutritional needs and weight loss, which of the following should not be included?
- A. knowledge of food and food products
- B. development of a positive mental attitude
- C. adequate exercise
- D. starting a fast weight-loss diet
Correct Answer: D
Rationale: When educating an obese client about nutritional needs and weight loss, it is important to cover factors such as knowledge of food and food products, the development of a positive mental attitude, and the importance of adequate exercise. These aspects contribute to a holistic approach to weight management. However, recommending the client to start a fast weight-loss diet should not be included. Fast weight-loss diets can be harmful, leading to health risks, nutrient deficiencies, and unsustainable outcomes. It is crucial to advocate for gradual, sustainable weight loss strategies to ensure long-term success and overall well-being. Therefore, starting a fast weight-loss diet is the least appropriate option among the choices provided.
When discussing birth control methods with a client, what major factor should a nurse focus on to provide the motivation needed for consistent implementation of a birth control method?
- A. Personal preference
- B. Work and home schedules
- C. Family planning goals
- D. Desire to have children in the future
Correct Answer: A
Rationale: When discussing birth control methods with a client, a nurse should focus on the client's personal preference as a major factor that will provide the motivation needed for consistent implementation of a birth control method. Personal preference plays a key role in ensuring that the chosen method aligns with the client's lifestyle and values, increasing the likelihood of adherence. While work and home schedules, family planning goals, and the desire to have children in the future can influence the choice of birth control method, they are not the primary motivating factors for consistent implementation. Personal preference is crucial as it empowers the client to select a method that suits their individual needs and preferences, ultimately leading to better compliance and effectiveness.
A nurse helps a young adult conduct a personal lifestyle assessment. The nurse carefully reviews the assessment with the young adult for which reason?
- A. Young adults may ignore physical symptoms and postpone seeking health care
- B. Young adults are unable to afford health insurance
- C. Young adults are at risk for a serious illness
- D. Young adults are exposed to hazardous substances
Correct Answer: A
Rationale: The corrected answer is A: Young adults may ignore physical symptoms and postpone seeking health care. Young adults are usually quite active, experience severe illnesses less commonly than members of older age groups, tend to ignore physical symptoms, and often postpone seeking health care. Clients in this developmental stage may benefit from a personal lifestyle assessment to identify habits that increase the risk for various chronic diseases. Choice B is incorrect because the ability to afford health insurance is not the primary reason for conducting a personal lifestyle assessment. Choice C is incorrect because young adults are not inherently at higher risk for serious illness compared to other age groups. Choice D is incorrect because exposure to hazardous substances is not the main focus when conducting a personal lifestyle assessment.
A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?
- A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
- B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
- C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
- D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.
Correct Answer: B
Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.
