If one parent has been affected by sickle cell anemia, while the other parent does not and is homozygous, the chances that a child will have this disorder is 0%. Thus, the correct option is C.

<h3>What is Sickle Cell anemia?</h3>

Sickle Cell anemia may be defined as a genetic disorder that is caused by a recessive allele. It is an inherited disease in which the red blood cells have an irregular crescent shape, obstruct small blood vessels, etc.

This disease is inherited when both genes of each parent are supposed to be defective or carriers. While in this case, only parents are affected by the disorder while the other is homozygous for the normal allele.

In this condition, all the offspring produced by both parents remain as carriers but not affected ones.

Thus, the correct option is C.

You are assessing a patient and notice he has a collapsed jugular vein. What does this indicate?
svlad2 [7]

Upon examination & assessment, a patient with collapsed jugular veins results in a clinical diagnosis of Hemothorax.

How is collapsed JVP related to hemothorax?

  • Hemothorax is the accumulation of blood between the visceral and parietal pleurae (pleural space).
  • Respiratory discomfort and tachypnea are common clinical findings in such individuals.
  • This exercise demonstrates hemothorax evaluation and treatment and discusses the role of the interprofessional team in improving care for individuals with this disease.

A frequent consequence of acute thoracic injuries is hemothorax.

  • It is a blood clot in the pleural space, which can be seen between the visceral and parietal pleura.
  • The most common mechanism of trauma is a blunt or penetrating injury to intrathoracic or extrathoracic tissues that leads to thoracic haemorrhage.

  • Bleeding can occur in the chest wall, intercostal or internal mammary arteries, major vessels, mediastinum, myocardium, lung parenchyma, diaphragm, or belly.
  • Although CT scanning is the preferred method of assessing intrathoracic injuries, it may not be practicable in individuals with unstable trauma.
  • The pulmonary windows are now included in the Extended-Focused Assessment with Sonography in Trauma (eFAST) technique.

Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
stealth61 [152]
The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.

However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs.
