A physician is teaching a group of medical students about the physiological basis for damage to the circulatory and neurological systems that can accompany hypotension.
 
  Which of the following responses by a student would warrant correction by the physician?
  A)
  As vessel wall thickness increases, tension decreases.
  B)
  Smaller blood vessels require more pressure to overcome wall tension.
  C)
  The smaller the vessel radius, the greater the pressure needed to keep it open.
  D)
  Tension and vessel thickness increase proportionately.

Question 2

The nurse practitioner working in an overnight sleep lab is assessing and diagnosing patients with sleep apnea. During this diagnostic procedure, the nurse notes that a patient's blood pressure is 162/97.
 
  The nurse explains this connection to the patient based on which of the following pathophysiological principles?
  A)
  During apneic periods, the patient experiences hypoxemia that stimulates chemoreceptors to induce vasoconstriction.
  B)
  When the patient starts to snore, his epiglottis is closed over the trachea.
  C)
  When the airway is obstructed, specialized cells located in the back of the throat send signals to the kidney to increase pulse rate.
  D)
  When airways are obstructed, the body will retain extracellular fluid so that this fluid can be shifted to intravascular space to increase volume.

Answer to Question 1

Ans:
D

Feedback:

Tension and vessel wall thickness are inversely proportionate, in that thinner blood vessels have greater tension and vice versa. Answer choices A, B, and C all express the correct inverse relationship between tension and wall thickness.

Answer to Question 2

Ans:
A

Feedback:

People with sleep apnea also may experience an increase in BP because of the hypoxemia that occurs during the apneic periods. The specialized chemoreceptors are located in carotid bodies and aortic bodies of the aorta. Retention of fluid is not the cause of increased BP during sleep apnea episodes.

Did you know?

ACTH levels are normally highest in the early morning (between 6 and 8 A.M.) and lowest in the evening (between 6 and 11 P.M.). Therefore, a doctor who suspects abnormal levels looks for low ACTH in the morning and high ACTH in the evening.

Did you know?

Patients who have been on total parenteral nutrition for more than a few days may need to have foods gradually reintroduced to give the digestive tract time to start working again.

Did you know?

Aspirin is the most widely used drug in the world. It has even been recognized as such by the Guinness Book of World Records.

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Did you know?

The toxic levels for lithium carbonate are close to the therapeutic levels. Signs of toxicity include fine hand tremor, polyuria, mild thirst, nausea, general discomfort, diarrhea, vomiting, drowsiness, muscular weakness, lack of coordination, ataxia, giddiness, tinnitus, and blurred vision.
