Answer:
A diastolic blood pressure is somewhere between people in their 90s and 60s its in older folks. Your coronary arteries are fed during the diastolic phase. If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen.
Hope this helps?
Diastolic blood pressure is the lower number in a blood pressure reading and it represents the pressure in the arteries when the heart rests between beats. Low diastolic blood pressure can indicate an internal hemorrhage or other issues like heart conditions. Optimal readings are around 80 mm Hg, and readings under 60 mm Hg could potentially indicate inadequate blood flow to the heart.
Explanation:Diastolic blood pressure is the lower number recorded when measuring arterial blood pressure, which represents the minimal value corresponding to the pressure that remains during ventricular relaxation. Low diastolic blood pressure may indicate an internal hemorrhage requiring a transfusion or a less serious cause like dehydration, certain medications, or heart conditions. Normal diastolic pressure ranges between 60 to 80 mm Hg, although optimal diastolic blood pressure is said to be 80 mm Hg. It is influenced by various factors, including stress, exercise, eating, and standing among others. Too low diastolic blood pressure, i.e. under 60 mm Hg., could lead to inadequate blood flow -- and therefore oxygen -- to the heart, especially in individuals with blocked heart arteries.

Which is a reason for drinking a sports drink during exercise?
A. Exercising less than an hour
B. Avoiding extra calories
C. Exercising in heat and humidity
D. Performing gentle stretches
Answer:
C. exercising in heat and humidity
Drinking a sports drink during exercise, especially in heat and humidity, helps replenish the water and electrolytes lost through perspiration, preventing dehydration.
Explanation:When working out in these conditions, your body significantly increases its perspiration rate to cool down. This process makes you lose notable quantities of water and electrolytes, such as sodium and potassium. A sports drink can effectively replenish these essential elements and prevent dehydration. It provides the fluid for rehydration and the electrolytes to help maintain body functions. However, for short durations of exercise, water is usually sufficient.

The menisci in the knee joint can be torn for a variety of reasons. considering the structure of the menisci would you expect these tears to heal on their own?
Answer:
Meniscus tears are not healed on their own.
Explanation:
The two most common causes of a meniscus tear are due to traumatic injury (often seen in athletes) and degenerative processes (seen in older patients who have more fragile cartilage). The most common mechanism of a traumatic meniscus tear occurs when the knee joint is flexed and the knee is then twisted.
The meniscus tear can only be surgically removed. However, in some cases people can live with the meniscus tear without any problem. Also, there are exercises that lessen the symptoms of this problem.
The most common symptoms of a meniscus tear are:
Knee pain Knee swelling Tenderness when pressing the meniscus Popping or clicking inside the knee Limited knee joint movementConrad Jackson is a 28-year-old man who presents to the emergency department with severe fatigue and dehydration secondary to a 4-day history of vomiting. During the interview, he describes attending a family reunion and states that perhaps he “ate something bad.” Upon admission his vital signs are a temperature of 102.7°F, heart rate of 116 bpm, respiratory rate of 18 breaths/min, and blood pressure of 86/54 mm Hg. The nurse also notes the patient has dry mucous membranes and tenting of skin. The physician orders an IV to be started with 0.45% normal saline, and orders a serum electrolytes and an arterial blood gas.
The following results are returned from the laboratory:
Sodium (Na+) 150
Potassium (K+) 5.5
Chloride (Cl¯) 110
BUN 42
Creatinine 0.8
Glucose 86
pH 7.32
PaCO2 35
HCO3¯ 20
PaO2 90
O2 Sat 98%
What is your interpretation of this arterial blood gas sample?
Hi !
Answer:
Sodium (Na+) 150 : high
Potassium (K+) 5.5 : high
Chloride (Cl¯) 110 : high
BUN 42 : high
Creatinine 0.8 : normal
Glucose 86 : normal
pH 7.32 : low
PaCO2 35 : normal
HCO3¯ 20 : low
PaO2 90 : normal
O2 Sat 98% ; normal
The arterial blood gas (ABG) sample reveals certain values indicating the acid-base status, oxygenation, and electrolyte levels in Conrad Jackson's blood.
pH: The pH of 7.32 indicates a slightly decreased (acidic) pH compared to the normal range (7.35 - 7.45). This suggests a mild acidosis.
PaCO₂ (Partial pressure of carbon dioxide): The PaCO₂ level of 35 mmHg is within the normal range (35 - 45 mmHg), suggesting normal respiratory function and adequate elimination of carbon dioxide.
HCO₃⁻ (Bicarbonate): The HCO₃¯ level of 20 mEq/L is slightly decreased compared to the normal range (22 - 26 mEq/L). This indicates a lower bicarbonate level, reflecting a metabolic acidosis.
O₂ Sat (Oxygen saturation): The O₂ Sat of 98% indicates normal oxygen saturation in the blood.
Based on the ABG results:
The pH is slightly acidic, suggesting a mild acidosis.
The PaCO₂ is normal, indicating normal respiratory function.
The decreased HCO₃¯ level suggests a metabolic acidosis, which could be due to dehydration and vomiting leading to an imbalance in electrolytes, especially chloride, and a buildup of metabolic acids.
Overall interpretation: Conrad Jackson appears to have a mild metabolic acidosis, likely secondary to dehydration and vomiting. The physician should address the acid-base imbalance and electrolyte disturbances by providing appropriate fluid replacement and treating the underlying cause of dehydration.

Goiter is caused primarily by a deficiency of
Answer: Iodine
Explanation:
Goitre is a disease which is caused by the deficiency of iodine. It can be seen as the swelling of the neck due to enlarged thyroid gland. The symptoms include the tight throat, hoarseness, difficulty in swallowing, difficulty in breathing and coughing. The individuals who take diet deficient of iodine are prone to this disease.
Goiter, an enlargement of the thyroid gland in the neck, is primarily caused by a deficiency in iodine. The thyroid gland uses iodine to produce hormones that regulate many bodily functions. If the body is lacking in iodine, the thyroid gland may grow larger to compensate, leading to a goiter.
Explanation:Goiter is primarily caused by a deficiency of the essential mineral, iodine. Iodine is crucial for the production of thyroid hormones, which regulate a variety of functions in our bodies, ranging from metabolism to growth. If the body is deficient in iodine, the thyroid gland, which is located in the neck, tries to compensate by growing larger, resulting in a goiter. A diet lacking in iodine-rich foods, such as seafood and dairy products, can lead to an iodine deficiency, and subsequently, a goiter.

The nurse is instructing the client on skin and sun protection. Which statement by the client indicates the need for further teaching?
a. My skin is better protected from the sun because I am dark skinned
b. Sunscreen should be applied liberally
c. I use a tanning bed to avoid the sun's harmful rays
d. My sunglasses are UVA and UVB protected
Answer: d. My sunglasses are UVA and UVB protected.
Explanation:
d. My sunglasses are UVA and UVB protected. is the correct option because here the client is claiming the fact that the sunglasses are UVA and UVB protected but the sunglasses will only protect the eyes but the not the skin. The sunscreen is likely to protect the skin from the harmful UV rays typically the UVA and UVB which can cause skin pigmentation and may burn the skin.
The statement needing further teaching is the use of tanning beds to avoid sun damage, which is incorrect because tanning beds emit harmful UV radiation similar to the sun.
Explanation:The statement by the client indicating the need for further teaching on skin and sun protection is: "I use a tanning bed to avoid the sun's harmful rays." This misconception requires correction because tanning beds emit UV radiation similar to that of the sun, which can still damage the skin and increase the risk of skin cancer. While it is true that sunscreen should be applied liberally and sunglasses should offer UVA and UVB protection, the belief that dark skin alone offers complete protection is also misleading. People with darker skin have more melanin, which does provide some protection, but it does not make them immune to UV damage or skin cancer risks.
As such, all individuals, regardless of skin color, should adopt comprehensive sun protection practices including the use of sunscreen with a high SPF, wearing protective clothing, and avoiding excessive sun exposure and tanning beds.

Allen the Troublemaker, a 19-year-old college student, was rock climbing when he fell 30 feet to the ground. Paramedics arriving at the scene found him lying in the supine position, unable to move any extremities and complaining of neck pain. He was awake, alert, and oriented to his current location, the date and day of the week, and the details of his fall. His responses to questioning were appropriate. He complained that he could not feel his arms and legs. His pupils were equal and reactive to light. He showed no other signs of injury except for several scrapes on his arms. His vital signs revealed a blood pressure of 110 / 72, heart rate of 82 beats per minute, respirations of 18 per minute. Vital signs were taken again at the hospital and were as follows: blood pressure=94 / 55; heart rate=64; respiratory rate=24 (with shallow breathing).Why did Allen's heart rate and blood pressure fall in this time of emergency (i.e. at a time when you'd expect just the opposite homeostatic responses)?
