Which nutrient is critical for wound healing and immune function?

Correct Answer: B

Rationale: In the context of pharmacology and nutrition, the correct answer to the question, "Which nutrient is critical for wound healing and immune function?" is Vitamin C (Option B). Vitamin C plays a crucial role in wound healing and immune function due to its involvement in collagen synthesis, an essential protein for skin repair. Additionally, Vitamin C acts as an antioxidant, helping to protect cells from damage and supporting immune cell function. Regarding the incorrect options: - Vitamin B12 (Option A) is important for nerve function and DNA synthesis but is not directly related to wound healing or immune function. - Vitamin D (Option C) is primarily known for its role in bone health and calcium absorption, rather than wound healing and immune function. - Vitamin K (Option D) is essential for blood clotting but is not directly linked to wound healing or immune function. Educationally, understanding the role of different nutrients in specific bodily functions is vital for healthcare professionals, especially pharmacologists. Knowing the functions of vitamins helps in prescribing appropriate supplements for patients with specific needs, such as those requiring support for wound healing or immune system modulation. This knowledge enhances patient care and contributes to better health outcomes.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Vitamin B12. When following a vegetarian diet, particularly a strict vegan diet that excludes all animal products, individuals are at a higher risk of Vitamin B12 deficiency. Vitamin B12 is primarily found in animal products like meat, fish, eggs, and dairy. This vitamin is crucial for nerve function, red blood cell production, and DNA synthesis. Option A) Vitamin C is less likely to be deficient in a vegetarian diet as it is abundant in fruits and vegetables commonly consumed by vegetarians. Option C) Vitamin A can be obtained from plant-based sources like carrots, sweet potatoes, and leafy greens, making it less of a concern for deficiency in vegetarian diets. Option D) Vitamin D deficiency is not specific to vegetarian diets and can be a concern for individuals with limited sun exposure or inadequate dietary intake, regardless of their dietary preferences. Educationally, this question highlights the importance of understanding the specific nutrient considerations when following different dietary patterns. It emphasizes the need for vegetarians, especially vegans, to be mindful of their Vitamin B12 intake through fortified foods or supplements to prevent deficiencies that could impact their health.

Correct Answer: B

Rationale: In the context of a client with a history of gout, the correct food to include in their diet is option B) Whole grains. Whole grains are beneficial for individuals with gout because they are low in purines. Purines are substances that break down into uric acid, which can exacerbate gout symptoms. By choosing whole grains over other options, the client can help lower their uric acid levels and reduce the risk of gout flares. Option A) Red meat is high in purines, which can lead to increased uric acid levels and trigger gout attacks. Therefore, red meat should be limited in the diet of someone with gout. Option C) High-fat dairy products can also contribute to increased uric acid levels, so they should be consumed in moderation or avoided by individuals with gout. Option D) Processed meats, similar to red meat, are high in purines and can worsen gout symptoms. Therefore, they are not recommended for individuals with gout. Educationally, understanding the impact of different foods on gout is crucial for healthcare professionals to provide appropriate dietary guidance to clients with this condition. By selecting low-purine foods like whole grains and avoiding high-purine foods, individuals with gout can better manage their symptoms and improve their overall quality of life.

Correct Answer: B

Rationale: In the context of pharmacology and healthcare, the correct answer, B) Talk to the relatives to gather data about history of illness, is the best way to identify the client's priority problem during an initial assessment. This approach allows for obtaining crucial information about the client's medical history, which can provide valuable insights into potential underlying conditions and risk factors. By gathering information from relatives, the healthcare provider can uncover important details that may not be readily available from the client. Option A, interviewing the client for chief complaints and other symptoms, is important in gathering the client's perspective. However, relying solely on the client's self-report may not provide a comprehensive picture, especially if the client is unable to communicate effectively or is unaware of certain aspects of their medical history. Option C, doing auscultation to check for chest congestion, and option D, conducting a physical examination while asking relevant questions, are important components of a comprehensive assessment but may not always reveal the client's priority problem during the initial assessment. In an educational context, this question highlights the significance of obtaining a thorough medical history, including information from relatives, to ensure a holistic approach to client care. Understanding the importance of gathering comprehensive data during the initial assessment is essential for healthcare providers, especially in pharmacology, to make informed decisions regarding medication management and treatment plans.

Correct Answer: C

Rationale: In the context of aging and constipation, the correct answer is C) loss of tone of the smooth muscles of the colon. As individuals age, there is a natural decrease in the tone of smooth muscles in the colon, leading to slower peristalsis and potentially causing constipation. This decrease in muscle tone results in reduced motility, making it harder for fecal matter to move through the intestines efficiently. Option A) inhibition of the parasympathetic reflex is incorrect because the parasympathetic nervous system is actually responsible for promoting digestion and peristalsis, so inhibition of this reflex would not predispose someone to constipation. Option B) weakness of sphincter muscles of anus is also incorrect. While weak sphincter muscles can contribute to fecal incontinence, they are not typically a primary factor in causing constipation. Option D) decreased ability to absorb fluids in the lower intestines is incorrect as well. While hydration is important for maintaining regular bowel movements, decreased fluid absorption in the lower intestines is not a common physiological change associated with aging that would predispose someone to constipation. Understanding the physiological changes that occur with aging and their impact on bowel function is crucial in nursing practice to effectively assess and manage constipation in older adults. Encouraging dietary fiber intake, adequate hydration, and physical activity can help mitigate the effects of age-related changes on bowel function.
