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.

Which of the following is a true statement?
A) The greater tubercle of the humerus articulates at the coracoid process of the scapula.
B) The rotator cuff is responsible for the flexible extensions at the elbow joint.
C) The head of the humerus articulates with the acromion process.
D) The annular ligament surrounds the head of the radius.
Answer:
The annular ligament surrounds the head of the radius.
The true statement is D) The annular ligament surrounds the head of the radius.
This ligament is important as it stabilizes the proximal radioulnar joint, allowing the radius to pivot around the ulna which facilitates the forearm's ability to rotate. It does not involve the greater tubercle, humeral head, scapular acromion, or the scapular coracoid process.

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.

Work of lovastatin in cholesterol reduction:
Explanation:
Cholesterol is necessary for the functioning of all human organs, however it has been associated that there is a relationship between increased blood cholesterol, atherosclerosis and coronary heart disease, thus drugs were developed that decrease cholesterol levels by decreasing also the incidence of myocardial infarction.
Since the 1950s when John Gofman, from the University of California at Berkeley studied the association between coronary heart disease and cholesterol, he discovered that there are more harmful forms of cholesterol called LDL or low-density lipoproteins and another with a protective effect, HDL or lipoproteins of high density, later the Framingham study confirmed this hypothesis, in the following decade in 1960, studies were continued by biochemists Konrad E. Bloch, Feodor Lynen, John Cornforth and George Popják who made them worthy of the Nobel prize by describing the Cholesterol synthesis in four stages, and gained importance in showing that the reduction of HMG-CoA to mevalonate is the main point in maintaining the cholesterol pathway, studies that were completed by Nobel Prize winners Bloch and Lynen.
The high cholesterol content in the diet prevents the simultaneous production of it by the liver, a mechanism regulated by HMG-CoA reductase that catalyzes the conversion of HMG-CoA into mevalonate, an enzyme that, when reduced, can contribute to reducing cholesterol levels. in plasma. Later, after several attempts, the Merck laboratory was able to demonstrate the efficacy of a molecule under the name of lovastatin that produced a significant decrease in plasma LDL levels.
Lovastatin is a selective and competitive inhibitor of the enzyme hydroxymethylglutaryl coenzyme A or HMG-CoA reductase, which catalyzes the reduction of HMG-CoA to mevalonate which is the basis for the formation of sterols and among them the synthesis of cholesterol. Lovastatin in its inactive form is a closed ring of gamma-lactone that, when activated, hydrolyzes to an open ring of β-hydroxy acid, producing a reversible inhibitory binding of HMG-CoA, its main effect is to prevent the formation of mevalonate, an essential component for the formation of cholesterol. In the liver, triglycerides and cholesterol bind to VLDLs and go to plasma to reach peripheral tissues. Low-density lipoproteins (LDL) are created from VLDLs.
Approximately 10% of cholesterol is synthesized in the liver and 15% in the intestine, being carried out in the microsomes and cytoplasm, acetyl-CoA, is a product of oxidation in the mitochondria and by the synthesis of fatty acids is transported to the citoplasma mainly, the process has five important steps:
1. Acetyl-CoAs are converted to 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA)
2. HMG-CoA is converted to mevalonate
3. Mevalonate is converted to the isoprene based molecule, isopentenyl pyrophosphate (IPP), with the concomitant loss of CO2
4. IPP are converted to squalene
5. Squalene is converted to cholesterol.
Lovastatin reduces plasma cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase and cholesterol synthesis in the liver and increasing the number of liver LDL receptors on the cell surface, which in turn increases absorption and catabolism of LDL. Lovastatin reduces LDL production and the number of LDL particles, increases the activity of LDL receptors, decreasing their plasma levels.
Thus today, new molecules continue to be produced with different specific applications, seeking a longer half-life or reduction of side effects, what is certain is that the discovery of lovastatin marks a historical fact for the treatment of cardiovascular disease.

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.

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.

Mary is in an automobile accident and suffers a spinal cord injury. She has lost feeling in her lower body. Her doctor tells her that swelling is compressing a portion of her spinal cord. Which part of her cord is likely to be compressed?A) ascending tracts in the cervical region of her spinal cord.
B) descending tracts in the cervical region of her spinal cord.
C) ascending tracts in the lumbar region of her spinal cord.
D) descending tracts in the lumbar region of her spinal cord.
E) the anterior white commissures.
Final answer:
The spinal cord injury that caused Mary to lose feeling in her lower body likely involves the compression of ascending tracts in the lumbar region of her spinal cord. Option C is correct.
Explanation:
Mary has lost feeling in her lower body due to a spinal cord injury. The loss of sensation suggests that the injury is impacting parts of the spinal cord responsible for sensory information. Considering that the sensations lost are in her lower body, the ascending tracts in the lumbar region of the spinal cord are likely compressed. These tracts carry sensory information from the body to the brain, and because the lumbar region corresponds to the lower part of the spinal cord, it controls sensations in the lower extremities. Therefore, the correct answer is C) ascending tracts in the lumbar region of her spinal cord.
