Central venous access devices (CVADs) are frequently utilized to administer chemotherapy. What is an advantage of using CVADs for chemotherapeutic agent administration?
- A. CVADs are more expensive than a peripheral IV.
- B. Weekly administration is possible.
- C. Chemotherapeutic agents can be caustic to smaller veins.
- D. The client or family can administer the drug at home.
Correct Answer: C
Rationale: The correct advantage of using CVADs for chemotherapeutic agent administration is that chemotherapeutic agents can be caustic to smaller veins. Many chemotherapeutic drugs are vesicants, which can cause tissue damage even in low concentrations. Using a CVAD to administer these agents into a large vein is optimal as it reduces the risk of damage. Choice A is incorrect as CVADs are actually more expensive than a peripheral IV, making it a disadvantage. Choice B is incorrect because the frequency of administration depends on the specific drug being administered, not on the access device, so it does not represent a universal advantage. Choice D is incorrect because IV chemotherapeutic agents are typically not self-administered at home; they are usually given in a hospital, outpatient, or clinic setting, making it an invalid advantage of using CVADs.

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.
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 is planning care for a hospitalized toddler. To best maintain the toddler's sense of control and security and ease feelings of helplessness and fear, the nurse should perform which action?
- A. Allow the toddler to play with other children in the nursing unit playroom.
- B. Spend as much time as possible with the toddler.
- C. Allow the toddler to select toys from the nursing unit playroom that can be brought into the toddler's hospital room.
- D. Keep hospital routines as similar as possible to those at home.
Correct Answer: D
Rationale: The best action for the nurse to take to help a hospitalized toddler maintain a sense of control and security and ease feelings of helplessness and fear is to keep hospital routines as similar as possible to those at home. By incorporating the toddler's usual rituals and routines from home into nursing care activities, the nurse can reduce the stress of hospitalization. This approach gives the toddler a sense of familiarity, control, and security, which can alleviate feelings of helplessness and fear. Allowing the toddler to play with other children in the nursing unit playroom and selecting toys are beneficial activities, but maintaining hospital routines similar to those at home is the most effective way to support the toddler's emotional well-being during hospitalization.
A nurse is caring for an older client who has a bronchopulmonary infection. The nurse monitors the client's ability to maintain a patent airway because of which factor involved in the normal aging process?
- A. Increased respiratory system compliance
- B. Decreased number of alveoli and increased function of those remaining
- C. Decreased older client's ability to clear secretions
- D. Increased production of surfactant
Correct Answer: C
Rationale: The correct answer is 'Decreased older client's ability to clear secretions.' Respiratory changes related to the normal aging process decrease an older adult's ability to clear secretions and protect the airway. In healthy older adults, the number of alveoli does not change significantly; their structure, however, is altered. Respiratory system compliance decreases with advancing age because of a progressive loss of elastic recoil of the lung parenchyma and conducting airways, and reduced elastic recoil of the lung and opposing forces of the chest wall. Production of surfactant in the lung does not usually decrease with aging, nor does it increase. However, the production of alveolar cells responsible for surfactant production is diminished. Choices A, B, and D are incorrect. Choice A is incorrect because respiratory system compliance decreases with aging. Choice B is incorrect as the number of alveoli does not significantly decrease in healthy older adults. Choice D is incorrect as the production of surfactant does not usually decrease with aging.
Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.
