Nursing Elites

1. What can the nurse instruct the mother of a teething 9-month-old infant to relieve discomfort?

• A. Rub the infant's gums with baby aspirin dissolved in water.
• B. Obtain an over-the-counter (OTC) topical medication for gum pain relief.
• C. Schedule an appointment with a dentist for a dental evaluation.
• D. Give the infant cool liquids or a Popsicle and hard foods such as dry toast.

Correct answer: D

Rationale: Teething in infants can cause discomfort, but it is a normal process. Symptoms may include nighttime awakening, daytime restlessness, excess drooling, and temporary loss of appetite. The recommended approach to relieve teething discomfort includes providing cool liquids, a Popsicle, or hard foods like dry toast for chewing. These items can help soothe the infant's gums. Rubbing the gums with baby aspirin dissolved in water is not recommended as it can be harmful. OTC topical medications are unnecessary for teething discomfort. Scheduling a dental evaluation is not required solely for teething. It's important to avoid home remedies like baby aspirin and opt for safer options like cool liquids. If necessary, acetaminophen (Tylenol) can be used under healthcare provider guidance to alleviate discomfort.

2. 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.

3. Social support systems include all of the following except:

• A. call-in help lines
• B. emotional assistance provided by others
• C. community support groups
• D. use of coping skills and verbalization for anger management

Correct answer: D

Rationale: The correct answer is the use of coping skills and verbalization for anger management. Social support systems involve external sources of support from others or the community. Call-in help lines, emotional assistance provided by others, and community support groups all represent social support systems where individuals can seek help and assistance from outside sources. On the other hand, the use of coping skills and verbalization for anger management refers to individual strategies rather than external social support.

4. A health care worker is concerned about a new mother being overwhelmed by caring for her infant. The health care worker should:

• A. immediately contact child protective services
• B. provide the mother with literature about child care
• C. consult a therapist to help the mother work out her fears
• D. refer the mother to parenting classes

Correct answer: D

Rationale: Prevention of child abuse is centered on teaching parents how to care for their child and cope with the demands of infant care. Parenting classes can help build self-confidence, self-esteem, and coping skills. Parents benefit by understanding the developmental needs of their children, while learning how to manage their home environment more effectively. The classes also increase the parents' social contacts and teach about community resources. Contacting child protective services (Choice A) is not appropriate in this scenario as there is no indication of abuse or neglect. Providing literature (Choice B) may not be as effective as parenting classes in addressing the mother's concerns. Consulting a therapist (Choice C) may be beneficial for underlying mental health issues, but parenting classes specifically focus on child care and coping skills, making Choice D the most suitable option in this situation.

5. 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 routinely used to flush an IV device before and after the administration of blood.
