Nursing Elites

1. Why might the physician order antibiotics to be given through the central venous access device (CVAD) rather than through a peripheral IV line if the CVAD becomes infected?

• A. To prevent infiltration of the peripheral line
• B. To reduce the pain and discomfort associated with antibiotic administration in a small vein
• C. To lessen the chance of an allergic reaction to the antibiotic
• D. To attempt to eliminate microorganisms in the catheter and prevent having to remove it

Correct answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

2. The mother of a newborn child is very upset. The child has a cleft lip and palate. The type of crisis this mother is experiencing is:

• A. reactive.
• B. maturational.
• C. situational.
• D. adventitious.

Correct answer: C

Rationale: The mother is experiencing a situational crisis as the unexpected birth of a child with a cleft lip and palate has placed her in a challenging situation she did not anticipate. This type of crisis is triggered by specific events and circumstances. Choice A, reactive, implies responding to a stressor after it has occurred, which is not the case here. Choice B, maturational, refers to stress related to developmental stages, not to external events like the child's condition. Choice D, adventitious, involves crises resulting from events outside one's control, such as natural disasters, which do not apply in this scenario.

3. Which of the following factors can impact an individual's ability to give informed consent?

• A. IQ
• B. educational level
• C. pain medications
• D. financial status

Correct answer: C

Rationale: Pain medications might alter alertness, thought processes, and reactions, potentially impacting an individual's ability to give informed consent. It is recommended to approach a client for consent at least 4 hours after the last dose of pain medicine to minimize any influence. Choices A, B, and D are incorrect. While IQ and educational level may affect how information is presented during the discussion process, they do not directly impact informed-consent decision-making. Financial status is also not a direct factor in an individual's ability to provide informed consent, unlike pain medications which can directly affect cognitive functions and decision-making abilities.

4. A nurse is teaching the mother of an 11-month-old infant how to clean the infant's teeth. The nurse tells the mother to take which action?

• A. Use a small amount of toothpaste and a soft-bristle toothbrush
• B. Use water and a cotton swab and rub the teeth
• C. Use diluted fluoride and rub the teeth with a soft washcloth
• D. Dip the infant's pacifier in maple syrup so that the infant will suck

Correct answer: C

Rationale: The correct action when cleaning an infant's teeth is to use water and a cotton swab to gently rub the teeth. This method helps in removing any food particles or plaque buildup without the risks associated with toothpaste ingestion. Using a small amount of toothpaste and a soft-bristle toothbrush is not recommended for infants as they may swallow the toothpaste, leading to potential fluoride ingestion issues. Using diluted fluoride and rubbing the teeth with a soft washcloth is unnecessary at this age since infants typically receive fluoride through other sources like formula. Dipping the infant's pacifier in maple syrup is highly inappropriate and poses a significant risk of tooth decay due to the high sugar content, which can harm the infant's teeth.

5. The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:

• A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
• B. have few, if any, side effects.
• C. are used to treat multiple types of cancer.
• D. are cell-cycle-specific agents.

Correct answer: A

Rationale: Alkylating agents, such as nitrogen mustards, are effective chemotherapeutic agents because they cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA. This cross-linking interferes with DNA replication and transcription, leading to cell death. Choice B is incorrect because alkylating agents have numerous side effects, including alopecia, nausea, vomiting, and myelosuppression. Choice C is incorrect because while nitrogen mustards are used to treat multiple types of cancer like chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, their effectiveness is primarily due to DNA cross-linkage. Choice D is incorrect because alkylating agents are non-cell-cycle-specific agents, meaning they can act on cells in any phase of the cell cycle, not just on cells that are actively dividing.
