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.

Quality is defined as a combination of all of the following except:
- A. conforming to standards.
- B. performing at the minimally acceptable level.
- C. meeting or exceeding customer requirements.
- D. exceeding customer expectations.
Correct Answer: B
Rationale: The correct answer is 'performing at the minimally acceptable level.' Quality is about meeting or exceeding customer requirements and expectations, as well as conforming to standards. The term 'performing at the minimally acceptable level' implies just meeting the minimum requirements, which falls short of the comprehensive definition of quality in terms of customer satisfaction and excellence. Therefore, this choice is the exception when defining quality. Choices A, C, and D align with the definition of quality as they all involve meeting or surpassing certain criteria for customer satisfaction and product excellence, which are essential components of quality management.
A nurse observes a nursing assistant communicating with a hearing-impaired client in later adulthood. The nurse should intervene if the nursing assistant performs which action?
- A. Uses short sentences
- B. Speaks at a normal rate and volume
- C. Uses facial expressions or gestures
- D. Overarticulates words
Correct Answer: D
Rationale: The correct answer is 'Overarticulates words.' When communicating with a hearing-impaired client who may rely on lip-reading, it is essential to speak clearly at a normal rate and volume. Overarticulating words can distort lip movements, making it harder for the client to understand. Using short sentences helps in conveying information effectively, allowing the client time to process. While facial expressions and gestures provide additional visual cues that aid in communication, overarticulating words can be counterproductive in this scenario. Therefore, the nursing assistant should avoid overarticulating words to ensure clear and concise communication for the client.
What causes an older female client's hair to turn gray?
- A. ''A loss of melanin occurs in the normal aging process.''
- B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
- C. ''The skin on the scalp becomes thin, causing moisture to escape.''
- D. ''It is caused by hereditary factors.''
Correct Answer: A
Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.
When assisting with data collection on language development in a toddler from a bilingual family, what characteristic would a nurse expect?
- A. Is more advanced than expected
- B. Is developing as expected
- C. Is slower than expected
- D. Will require assistance from a speech therapist
Correct Answer: C
Rationale: When assessing language development in a toddler from a bilingual family, a nurse would expect the child's language development to be slower than expected. Various factors, such as physical maturity and reinforcement received, can influence the pace of language development. Children from bilingual families, twins, and non-firstborn children may exhibit slower language development. Therefore, it is common for the language development of a toddler from a bilingual family to be slower than expected. This characteristic does not necessarily imply a need for speech therapy. Choices A, B, and D are incorrect because, in this context, the language development of the child is more likely to be slower than expected rather than more advanced, developing as expected, or requiring speech therapy.
A nurse is providing information to a group of pregnant clients and their partners about the psychosocial development of an infant. Using Erikson's theory of psychosocial development, the nurse tells the group that infants have which developmental need?
- A. Must have needs ignored for short periods to develop a healthy personality
- B. Need to rely on the fact that their needs will be met
- C. Need to experience frustration, so it is best to allow an infant to cry for a while before meeting his or her needs
- D. Need to tolerate a great deal of frustration and discomfort to develop a healthy personality
Correct Answer: B
Rationale: According to Erikson's theory of psychosocial development, infants struggle to establish a sense of basic trust rather than a sense of basic mistrust in their world, their caregivers, and themselves. If provided with consistent satisfying experiences that are delivered in a timely manner, infants come to rely on the fact that their needs are met and that, in turn, they will be able to tolerate some degree of frustration and discomfort until those needs are met. This sense of confidence is an early form of trust and provides the foundation for a healthy personality. Therefore, options A, C, and D are incorrect as they do not align with Erikson's theory that emphasizes the importance of infants trusting that their needs will be met.
