A school nurse provides information to the parents of school-age children regarding appropriate dental care. The nurse tells the parents that their children should perform which action?

Correct Answer: A

Rationale: School-age children are capable of taking responsibility for their own dental hygiene. Establishing good oral health habits during childhood can lead to a lifetime of cavity prevention. The nurse advises the parents that their children should brush with fluoride toothpaste and floss between their teeth after meals and before bedtime. This routine helps maintain good oral health and teaches children the importance of dental care. Choice A is the correct answer as it emphasizes both brushing and flossing after meals and at bedtime, which are crucial for effective dental care. Choices B, C, and D are incorrect as they do not stress the significance of both brushing and flossing after meals, which is essential for proper oral hygiene.

Correct Answer: C

Rationale: In later adulthood, age-related findings include trophic changes associated with arterial insufficiency, such as thin, shiny skin; thin, ridged toenails; and loss of hair on the lower legs. These changes occur normally with aging. Thick skin on the lower legs would not be an expected age-related finding as it typically indicates chronic venous insufficiency. A bounding dorsalis pedis pulse is not typical in later adulthood and may indicate arterial insufficiency, which is not an age-related finding.

Correct Answer: A

Rationale: The correct answer is varicella. Varicella vaccine contains a live, weakened form of the varicella-zoster virus. Choice B, IPV (inactivated poliovirus vaccine), is an inactivated vaccine, not a live virus vaccine. Choices C and D, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and hepatitis B vaccine, respectively, do not contain live viruses. Varicella is the only live virus vaccine among the options.

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.

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.

Correct Answer: D

Rationale: Individuals living in poverty often face barriers to accessing regular healthcare services, leading them to utilize Emergency Departments or urgent care centers as their primary source of healthcare. These facilities provide immediate care without the need for appointments or insurance, making them more accessible to those in poverty. While primary care physicians and neighborhood clinics are essential for preventive care, individuals in poverty may have difficulty accessing these services due to financial constraints or lack of insurance. Specialists typically require referrals and may not be easily accessible to individuals without stable healthcare coverage. Therefore, Emergency Departments or urgent care centers are the most likely healthcare option for people living in poverty.

Correct Answer: C

Rationale: The correct answer is 'confidence in subordinates.' If a delegator has confidence in their subordinates' abilities, they are more likely to delegate tasks. Reasons why nurses are reluctant to delegate include their own lack of self-confidence, the desire to maintain authority, and getting trapped in the 'I can do it better myself' mindset. Therefore, having confidence in subordinates is not a common reason for reluctance to delegate.

Correct Answer: A

Rationale: For clients with dysphagia, ensuring successful swallowing of food and preventing aspiration is crucial. Therefore, the nurse should suggest monitoring the client closely during meals to provide assistance as needed. While a balanced diet is important, special considerations like adding thickeners for liquids may be required for dysphagia clients. Consulting with a physician about enteral tube feeding should be based on the severity of the condition, making it a premature step without clear indications. Encouraging self-feeding may not be appropriate for dysphagia clients who require close monitoring and assistance, as it could increase the risk of complications.

Correct Answer: A

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.
