The blood vessels serving alveoli are part of the pulmonary circulation, which involves the flow of blood between the heart and lungs. This is true.
What is Pulmonary and Systemic circulation?
Pulmonary circulation consists of blood vessels responsible for carrying deoxygenated blood from the heart to the alveoli in the lungs and then carrying oxygenated blood back to the heart.
The bronchial vessels, on the other hand, are part of the systemic circulation, which supplies oxygenated blood and nutrients to the tissues of the body, including the lung tissue itself. In contrast, the bronchial vessels, which supply blood to the tissues of the lungs themselves, are part of the systemic circulation that serves the rest of the body.

If the RX is OS +1.00 +3.00 x45, what would be the total power at axis power 90?
A. +1.00
B. +2.00
C. +2.25
D. +2.50
The total power at axis power 90 for RX OS +1.00 +3.00 x45 is B) +2.00.
When the axis power is at 90, the cylindrical power of the prescription does not come into play. Therefore, the total power at axis power 90 is equal to the spherical power, which in this case is +1.00. However, when calculating the power of the prescription, it is important to consider the axis angle of the cylindrical power.
In this case, the cylindrical power is +3.00 at axis 45. To convert this power to its equivalent power at axis power 90, we must use the power cross formula.
The power cross formula shows that the equivalent power at axis power 90 is equal to the spherical power plus the cylindrical power multiplied by the cosine of the difference between the axis angle and 90.
Using this formula, we can calculate that the cylindrical power at axis power 90 is +1.00, which, when added to the spherical power of +1.00, gives a total power of +2.00(B).

A 68 yo male presents with complaints of an aching pain in both thighs when he walks about one block. Perform an ankle brachial index (ABI) as the best initial test in this case.
An ankle brachial index (ABI) is a non-invasive test that compares the blood pressure in the ankle to the blood pressure in the arm. A low ABI suggests narrowing or blockage of the arteries in the legs, which can cause symptoms of claudication (pain or cramping in the legs with exercise). It is a simple and reliable test to diagnose peripheral artery disease (PAD), which is a common cause of claudication in older adults. PVR and MRA can also diagnose PAD, but are more expensive and less readily available than ABI. Ultrasound is useful for diagnosing blood clots, but not as useful for diagnosing PAD.

An 80 yo on warfarin has an INR of 2.5. The best explanation for increased bleeding risk compared with a younger patient is
The 80-year-old patient is at an increased risk of bleeding compared to a younger patient due to several factors.
Firstly, as we age, our blood vessels become more fragile and susceptible to damage, which can increase the risk of bleeding. Secondly, the 80-year-old patient may have other underlying medical conditions, such as hypertension or diabetes, which can further increase the risk of bleeding. Finally, the fact that the patient is on warfarin, an anticoagulant medication, means that their blood is less able to clot and stop bleeding. Therefore, even a small injury or cut can lead to significant bleeding, especially if the patient's INR is higher than the therapeutic range. It is essential to monitor the patient's INR regularly to ensure they are within the therapeutic range and to take necessary precautions to prevent bleeding. The best explanation for the increased bleeding risk in an 80-year-old patient on warfarin with an INR of 2.5 compared to a younger patient is that older individuals often have age-related physiological changes, such as reduced liver function, decreased renal clearance, and increased sensitivity to medications, which can affect their response to warfarin and increase the likelihood of bleeding complications.

What is the approximate TEF of a 260-calorie plain bagel?
The TEF of a 260-calorie plain bagel would be approximately 13-26 calories (5-10% of 260 calories).A 260-calorie plain bagel is primarily composed of carbohydrates, with some small amounts of protein and fat.
On average, the TEF of carbohydrates is around 5-10% of the energy consumed, while the TEF of protein is around 20-30%. Fats have the lowest TEF, at around 0-5%. The thermic effect of food (TEF) is the amount of energy required by the body to digest, absorb and metabolize the nutrients in food. The TEF varies depending on the macronutrient composition of the food consumed. Proteins have the highest TEF, followed by carbohydrates and then fats. Based on this information, the TEF of a 260-calorie plain bagel would be approximately 13-26 calories (5-10% of 260 calories). However, it is important to note that individual factors such as age, gender, body composition, and physical activity levels can affect TEF. Overall, while TEF does contribute to overall energy expenditure, it is not a major factor in weight loss or weight gain. Instead, creating a calorie deficit through a balanced diet and regular exercise is the most effective way to achieve and maintain a healthy weight.For more such question on carbohydrates

Where should you insert the scope when evaluating velopharyngeal function?
When evaluating velopharyngeal function, the scope should be inserted through the nasal cavity into the pharynx, allowing for direct visualization of the velopharyngeal mechanism. This is typically done with an endoscope or a nasendoscope.
1. Choose the appropriate scope: Use a flexible nasopharyngoscope or an endoscope for the examination.
2. Prepare the patient: Have the patient seated in a comfortable position. You may use a topical anesthetic to numb the nasal passages and reduce discomfort.
3. Insert the scope: Gently insert the scope through the patient's nasal cavity, being careful not to cause any discomfort.
4. Visualize the velopharyngeal structures: As you advance the scope, you will be able to visualize the velum (soft palate), lateral and posterior pharyngeal walls, and the adenoids.
5. Assess velopharyngeal function: Have the patient perform various tasks, such as speaking, swallowing, or blowing, to evaluate the function of the velopharyngeal structures. Observe for any abnormalities or inadequate closure during these tasks.
By following these steps, you can effectively assess the velopharyngeal function using a scope inserted through the nasal cavity.
