Correct Answer: B

Rationale: The correct answer is B: "Good oral hygiene is needed, including brushing and flossing." This is because phenytoin (Dilantin) can cause gingival hyperplasia, a side effect that leads to overgrowth of gum tissue. Good oral hygiene practices, such as regular brushing and flossing, can help prevent or minimize this side effect. Choice A is incorrect because alcohol is contraindicated while taking phenytoin as it can increase the risk of side effects and decrease the effectiveness of the medication. Choice C is incorrect because medication doses should never be self-adjusted without consulting a healthcare provider, as this can lead to ineffective treatment or potential harm. Choice D is incorrect because the timing of the morning dose in relation to drawing a serum drug level is not relevant to the client's understanding of medication instructions and does not address the specific side effect of gingival hyperplasia associated with phenytoin.

Correct Answer: A

Rationale: The correct answer is A: Positive family history. Pernicious anemia is an autoimmune condition where the body attacks its own intrinsic factor, leading to vitamin B12 deficiency. Genetic predisposition plays a significant role in the development of pernicious anemia. Family history is a key risk factor as individuals with a family history of pernicious anemia are more likely to develop the condition. Summary of why the other choices are incorrect: B: Infectious agents or toxins do not directly cause pernicious anemia, although they can lead to other types of anemia. C: Acute or chronic blood loss can result in iron-deficiency anemia, not pernicious anemia. D: Inadequate dietary intake of vitamin B12 can lead to vitamin B12 deficiency anemia, but pernicious anemia specifically involves the body's inability to absorb B12 due to intrinsic factor deficiency, not dietary intake alone.

Correct Answer: C

Rationale: The correct answer is C: Dopamine. Parkinson's disease is primarily caused by a deficiency of dopamine in the brain, leading to the characteristic symptoms of bradykinesia, rigidity, and tremors. Dopamine is a neurotransmitter involved in movement control. Acetylcholine (Choice A) is not directly related to Parkinson's disease, although its imbalance can contribute to other movement disorders. Serotonin (Choice B) and Phenylalanine (Choice D) are not primarily involved in the pathophysiology of Parkinson's disease.

Correct Answer: B

Rationale: The correct answer is B: Ask her to demonstrate her ability to ambulate. This response is best because it allows the nurse to assess the patient's actual ability to walk safely to the bathroom. By observing her, the nurse can ensure her safety and prevent potential falls. This approach also respects the patient's autonomy while prioritizing her safety. Incorrect responses: A: Allowing her to ambulate unassisted solely for positive self-esteem overlooks the importance of assessing her actual capability and ensuring safety. C: Explaining that assistance will always be available may not address the immediate need for assessment and safety. D: Asking another staff member to assist without assessing the patient's ability herself does not allow the nurse to directly evaluate the patient's safety and independence.

Correct Answer: C

Rationale: The correct answer is C because it shows a positive self-perception and self-acceptance. By choosing the dress based on how it complements her eyes, the patient demonstrates a focus on her own preferences and self-image rather than external validation or criticism. This indicates progress towards accepting her body image. A: Choice A indicates concern about others' opinions, which shows a lack of self-assurance and reliance on external validation. B: Choice B reflects negative body image and self-criticism, indicating a lack of acceptance. D: Choice D is focused on a future event, suggesting avoidance or delay in addressing the current body image issues.
