Parts 1 And 2 Can Have The Same Questions However You Must Answer Wi

Parts 1 and 2 can have the same questions. However, you must answer with references and different writing, always addressing them objectively, as if you were different students. Similar responses in wording or references will not be accepted. The number of words in each paragraph should be similar.

Part 1: minimum 6 pages (Due 24 hours). Part 2: minimum 8 pages (Due 48 hours). Submit 1 document per part.

2)¨APA norms. The number of words in each paragraph should be similar. Must be written in the third person. All paragraphs must be narrative and cited in the text—each paragraph. The writing must be coherent, using connectors or conjunctives to extend, add information, or contrast information.

Bulleted responses are not accepted. Don't write in the first person. Do not use subtitles or titles. Answer the question objectively, avoiding copy-paste from the internet. No placeholders or meta instructions.

All responses will be checked via Turnitin and SafeAssign for similarity.

4) Minimum 4 references per part, APA format, not older than 5 years, no websites, must align with the topic. Different references are not allowed.

5) Number the answers according to the question, starting directly on the same line.

6) Name files according to the part being answered: Example: Part 1.doc, Part 2.doc.

Part 1: Original responses to the specified questions on primary healthcare topics

1. The pharmacologic action of anticoagulation in the cardiovascular system primarily involves the inhibition of the clotting cascade to prevent thrombus formation. Anticoagulants like heparin accelerate the activity of antithrombin III, which inhibits thrombin and factor Xa, reducing fibrin formation. Alternatively, warfarin interferes with vitamin K epoxide reductase, impairing synthesis of vitamin K-dependent clotting factors II, VII, IX, and X, leading to decreased clot formation. The overall effect diminishes the blood's ability to form pathological clots within blood vessels, thus reducing complications such as stroke or myocardial infarction (Kumar & Clark, 2020).

2. The purpose of anticoagulation therapy in the cardiovascular system is to prevent, treat, or reduce the risk of blood clots that can lead to serious thromboembolic events. Conditions such as atrial fibrillation, deep vein thrombosis, and pulmonary embolism benefit from anticoagulation by decreasing the likelihood of clot formation, which can obstruct blood flow or embolize to vital organs like the brain or lungs. Such interventions aim to improve patient outcomes by minimizing morbidity and mortality associated with thrombotic events (Cappell et al., 2021).

3. Assessing aortic regurgitation involves clinical, auscultatory, and imaging techniques. Clinically, symptoms such as exertional dyspnea, palpitations, and fatigue are noted. On physical examination, a characteristic diastolic murmur loudest at the left sternal border indicates aortic regurgitation. Echocardiography remains the gold standard for evaluation, allowing visualization of the regurgitant flow, measuring the regurgitant volume, and assessing left ventricular size and function, which are vital for determining severity and guiding management (Nishimura et al., 2019).

4. Pharmacological treatment for acne vulgaris includes topical agents like benzoyl peroxide, retinoids, and antibiotics such as clindamycin or erythromycin. Systemic therapies involve oral isotretinoin for severe cases, hormonal contraceptives for hormonal acne, and antibiotics like doxycycline or minocycline to reduce inflammation and bacterial proliferation. These treatments target reduce sebum production, bacterial colonization, and inflammation, thus alleviating the clinical presentation (Zaenglein et al., 2016).

5. Assessing aging skin involves a combination of visual inspection and functional evaluation. Clinicians look for signs such as wrinkles, loss of elasticity, dryness, and age spots. Functional assessments include measuring skin turgor, hydration, and capacity for wound healing. Histologically, aging skin exhibits decreased collagen and elastin fibers, increased matrix metalloproteinases, and alterations in epidermal thickness, all contributing to the characteristic changes observed clinically (Keller et al., 2020).

6. The pathophysiology of tinea involves superficial fungal infection caused by dermatophytes, which invade keratinized tissues like skin, hair, and nails. The fungi produce keratinases that degrade keratin, facilitating colonization and invasion. The immune response to dermatophyte invasion results in inflammation, characterized by erythema, scaling, and itching. The infection remains localized but can spread if untreated, perpetuated by warm, moist environments conducive to fungal growth (Paladini et al., 2019).

7. Assessing diabetic retinopathy involves ophthalmologic examination including visual acuity testing, slit-lamp examination, and fundoscopy. Key features include microaneurysms, hemorrhages, exudates, neovascularization, and retinal detachment. Fluorescein angiography may be used to assess retinal blood vessels for areas of leakage or ischemia. Early identification is crucial, as diabetic retinopathy can progress to vision loss if untreated (Yau et al., 2019).

8. Hyperopia assessment includes visual acuity testing with eye charts, refraction to determine the degree of farsightedness, and binocular vision examination. Additional tests such as retinoscopy may also be performed to objectively measure refractive errors. Patients typically complain of blurry distance vision, eye strain, or headaches. Examination of the ocular anatomy, including corneal curvature and axial length, provides insights into the structural basis of hyperopia (Nussbaum et al., 2020).

9. Anemia’s pathophysiology involves decreased red blood cell production, increased destruction, or blood loss, leading to reduced oxygen-carrying capacity. Depending on the type, such as iron deficiency anemia, there is inadequate hemoglobin synthesis due to iron deficiency, impairing oxygen delivery. Hemolytic anemias involve premature destruction of RBCs, while blood loss causes decreased RBC volume. The systemic hypoxia affects tissues, leading to fatigue, pallor, and tachycardia (Begum et al., 2020).

10. Assessing pernicious anemia involves reviewing clinical history, physical examination, and laboratory tests. Key features include macrocytic anemia identified via CBC, elevated folate, and low vitamin B12 levels. Examination findings such as pallor, glossitis, and neurological symptoms like paresthesia are noted. Schilling test historically evaluated intrinsic factor deficiency. Endoscopic gastric biopsy may reveal atrophic gastritis. The assessment aims to identify vitamin B12 malabsorption as the underlying cause (Lindgren et al., 2019).
