Explanation:
during exercise,there is receptors which are present in skeletal muscle ,send sensory afferent to CAC ,in turn stimulate If,so amount of oxygen to muscles increase
Smallpox is no longer a threat to anyone in the United States. And the vaccination against it is unpleasant and, in rare cases, life-threatening. conclusion : We were wise when we ceased the routine vaccination of our children.'
The steps to follow in an emergency are:
A-Call-Check-Secure.
B-Care-Call-Check.
C-Check-Call-Care
D-Check-Care-Defibrillate
Final answer:
The steps to follow in an emergency are Check-Call-Care. This procedure involves checking the area for safety, checking the victim, calling for help, and caring for the victim until professional help arrives. AEDs are essential and user-friendly devices that can assist in cardiac emergencies.
Explanation:
The correct steps to follow in an emergency are C-Check-Call-Care. Initially, one must Check the scene to ensure it's safe before approaching the victim. Once safety is confirmed, you Check the victim for responsiveness and breathing. After assessing the situation, you Call for emergency services (such as 911 in the United States) for professional medical help. Finally, you provide Care by performing first aid or CPR if you are trained to do so. In certain cases where a cardiac emergency is suspected, the use of an automated external defibrillator (AED) may be necessary. As per the information provided, AEDs are designed to be user-friendly and can be found in many public places. They come with verbal instructions and will automatically diagnose the patient’s heart rhythm to apply the correct shock, which can save a life during the early minutes of a cardiac attack. It is essential that everyone learns about these lifesaving steps, for instance through programs like Be The Beat, which raises awareness about Sudden Cardiac Arrest.
A 23 year old, overweight, black woman with a history of hemolytic anemia presents to the emergency department with fever and right upper quadrant pain. A right upper quadrant ultrasound is performed which demonstrates gallstones, a thickened gallbladder wall, and pericholecystic fluid. which patient characteristic puts her at higest risk of developing acute cholecystitis?a.female sexb.young agec.ethnicityd.patients with hemolytice.anemiaf.obesity
Answer:
A, D, and F are most correct (female sex, hemolytic anemia, and obesity)
Explanation:
Acute cholecystitis is the inflammation of the gallbladder, an organ whose main function is to act as a reservoir of bile (a substance made by the liver which helps digest fats). The pathophysiology of this disease is characterized by the presence of stones in the gallbladder, known as gallstones, which block the duct, obstructing the exit of this fluid and favoring inflammation/infection of the organ.
To answer this question, one has to know the risk factors of producing gallstones. An easy way to remember is with the ”F” rule:
Female: Women are more affected than menForty: Refers to the age that the patient has higher riskFertile: Women who had multiple pregnancies (due to the high concentration of estrogens, which promote the production of gallstones)Fat: Obese patients have higher concentration of steroid hormones, promoting production of gallstonesFair: Normally fair skinned people tend to have increased risk.Additionally, hemolytic anemia is associated with production of pigmented gallstones due to the increased breakdown of red blood cells.
If one had to chose one answer for this specific case, the most likely answer would be hemolytic anemia, since this patient is relatively young and has not been exposed to increased concentration of steroid hormones for a long time In her lifespan. Nevertheless, female sex and obesity still are technically correct answers.
The characteristic that puts the patient at the highest risk of developing acute cholecystitis is obesity. Hence, the correct option is f.
Obesity increases the cholesterol in the bile which in turn increases the risk of developing gallstones. These gallstones, when lodged in ducts, can lead to acute cholecystitis, a sudden onset of gallbladder inflammation that may necessitate medical intervention, such as surgery.
Infectious disease of humans whose occurrence during the past two decades has substantially increased or threatens to increase in the near future relative to populations affected, geographic distribution, or magnitude of impacts is known as: Select one: a. Modern hazard b. Emerging and reemerging disease c. Contemporary disease d. Antibiotic resistance
Answer:
b. Emerging and reemerging disease
Explanation:
Emerging and reemerging disease are infectious diseases which showed growth in last two decades by targeting large populations, spreading in many geographical areas and demonstrating an increased fatality rate. For example, Ebola and HIV AIDS.
These infections emerged because of presence of many favorable factors at the same time. Increasing population made it easier for the infection to spread because it is difficult to maintain a distance between people now. Increase in global travel also increased the chances of contacting the virus as the carrier can take it to a new unaffected region. Change in temperature also made it favorable for many viruses to propagate.
A heavyset middle-aged insurance salesman who doesn't exercise often accepts his friend's invitation to a pickup basketball game. When attempting a jump shot, he falls to the ground in pain, grasping at the calf of his leg. There is an enormous bulge in his leg immediately below the knee, and he is unable to plantar flex that foot. Most likely he has injured his ___ and the bulge is ___.
Answer:Calcaneal tendon; his triceps surae
Explanation:
The Calcaneal tendon which is also called Achilles tendon is the thickest tendon located at the back of the leg that attaches the plantaris,calf and soleus muscles to the calcaneal bone. These muscles acting together at the tendon is responsible for plantar flexion of the foot of the ankle
The triceps surae on the other hand consisting of two muscles forms the main mass of the calf which are the gastrocnemius and the soleus which join their tendons of into the midline of the leg into one tendon by inserting at the calcaneal tendon are responsble for providing flexion of the leg
Therefore, the heavyset man who falls to the ground in pain, grasping at the calf of his leg and having an enormous bulge in his leg immediately below the knee, with the inability to plantar flex his foot must have injured his _Calcaneal tendon__ and the bulge is _triceps surae because those are the site for these tendon and muscle
What bones are involved in the radiocarpal joint?
Radius
Scaphoid
Lunate
Triquetrum
The radiocarpal joint comprises the scaphoid, lunate, and triquetrum carpal bones, and the distal end of the radius, but not directly with the ulna, which is connected to the joint via a fibrocartilaginous pad.
The bones involved in the radiocarpal joint, which is the main joint of the wrist, are the scaphoid, lunate, and triquetrum from the proximal row of the carpal bones, as well as the distal end of the radius. Although the ulna is part of the forearm and lies next to the radius, it does not directly articulate with the carpal bones in the radiocarpal joint. Instead, the triquetrum bone articulates with a fibrocartilaginous pad between the radius and the styloid process of the ulna. The movement and function of the hand at the wrist are primarily dictated by the radiocarpal joint in conjunction with the midcarpal joint, where the proximal and distal rows of carpal bones interact.
leslie gunther is scheduled for surgery today ag 1 p.m. The hospital calls this morning to state the PAT information is not in her chart. You pull up leslie’s electronic chart snd see documentation that states the information was sent electronically to the hospital three days ago what would you do?
Answer:
vhj
Explanation:
Final answer:
In the case of missing Pre-Admission Testing (PAT) information for a surgery, verify the communication records, contact the hospital to resolve the issue, and prepare a contingency plan to resubmit the PAT information if necessary, ensuring professionalism and efficiency.
Explanation:
In a healthcare setting, when there is a concern about missing Pre-Admission Testing (PAT) information, it is imperative to act swiftly to ensure patient safety and to maintain the quality of care. Since the electronic chart indicates that the information was sent to the hospital three days ago, the next step should involve verifying the communication.
This can be done by checking if there is a confirmation receipt or any other evidence of successful transmission. If there is proof of sending the PAT information, one should contact the hospital to clarify and rectify the situation.
This would involve reaching out to the appropriate department or individual to ensure that they locate the information in their system. Sometimes electronic information can end up in the wrong folder or be overlooked due to human error.
Which of the following is a possible delay in in-hospital care to definitive treatment for patients experiencing an acute myocardial infarction?
What is the correct answer?
1. Door to data
2. Data to decision
3. Decision to terminate treatment
4. Door to vital sign exam
Final answer:
The potential delay in in-hospital care for an acute myocardial infarction patient is the 2) 'Data to decision' phase. It involves the time taken to process clinical information and reach a treatment decision, which is critical in acute cases.
Explanation:
The correct answer to the question is option 2: Data to decision. A delay in this stage occurs when there is a gap between obtaining clinical information and the care team's decision on the treatment approach. During this time, critical decisions about how to manage an acute myocardial infarction are made, and any delay can adversely affect patient outcomes. Conversely, 'Door to data' would refer to the time taken to gather initial information upon patient arrival. 'Decision to terminate treatment' is related to end-of-life care, and 'Door to vital sign exam' describes the initial assessment of a patient, which typically does not involve a delay significant enough to impact definitive treatment for an acute condition such as a heart attack.
