1. Which of the following are the primary bacteria involved in the initiation of dental caries?

• A. Streptococcus mutans and Lactobacillus species
• B. Salmonella and Listeria species
• C. Streptococcus, Lactobacillus, and Salmonella species
• D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

2. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?

• A. Trim nails using a nail clipper
• B. Apply cornstarch to the foot
• C. Always check the temperature of the water before bathing
• D. Use canvas shoes

Correct answer: A

Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.

3. Which outcome has been shown to be most closely associated with breastfeeding infants of mothers who smoke?

• A. poor temperature regulation
• B. vision impairment
• C. vomiting
• D. elevated blood pressure

Correct answer: C

Rationale: The correct answer is C: vomiting. Infants breastfed by mothers who smoke are more likely to experience vomiting and gastrointestinal issues due to the transfer of nicotine and other harmful substances through breast milk. Choices A, B, and D are incorrect. Poor temperature regulation, vision impairment, and elevated blood pressure are not the primary outcomes closely associated with breastfeeding infants of mothers who smoke.

4. A group of clients is being instructed by a nurse regarding nutrition. The teaching should state that which of the following groups of foods contains the highest level of carbohydrates?

• A. Milk, eggs, and cheese
• B. Butter, oils, and avocados
• C. Rice, potatoes, and oranges
• D. Chicken, green beans, and apples

Correct answer: C

Rationale: The correct answer is C: Rice, potatoes, and oranges. These foods are rich in carbohydrates. Choice A (Milk, eggs, and cheese) contains minimal carbohydrates as they are primarily sources of protein and fat. Choice B (Butter, oils, and avocados) contains very little to no carbohydrates as they are high in fats. Choice D (Chicken, green beans, and apples) also contains minimal carbohydrates, with protein and fiber being more prominent in these foods.

5. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

• A. Natural active immunity
• B. Natural passive immunity
• C. Artificial active immunity
• D. Artificial passive immunity

Correct answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
