Flashcards

Why is the liver not visible on a CXR?

A CXR is an X-ray of the chest. The liver is not typically visible on a CXR because it is located behind the ribs. The hilar region, diaphragm, and cardiac silhouette are all visible on a CXR.

What does ventricular repolarization represent?

Ventricular repolarization is the process of the ventricles returning to their resting state after contraction. This is associated with relaxation.

Why does the left ventricle have the thickest wall?

The left ventricle is responsible for pumping oxygenated blood to the entire body. It needs a thicker wall to generate the force necessary for systemic circulation.

What does the P wave on an EKG represent?

The P wave on an EKG represents atrial depolarization, the electrical signal that causes the atria to contract.

What does the QRS complex on an EKG represent?

The QRS complex on an EKG represents ventricular depolarization, the electrical signal that causes the ventricles to contract. It is also sometimes associated with atrial repolarization, but this is very small and usually not visible.

Can a hiatal hernia be detected on a CXR if the stomach is seen below the diaphragm?

A hiatal hernia occurs when a portion of the stomach protrudes through the diaphragm. It can be detected on a CXR if the stomach is seen above the diaphragm, not below.

Why is the right diaphragm higher than the left?

The right lung is slightly higher than the left lung due to the location of the liver.

Study Notes

Multiple Choice Questions

  • Question 1: A chest X-ray (CXR) typically does not show the cardiac silhouette.
  • Question 2: Ventricular repolarization represents ventricular relaxation.
  • Question 3: The left ventricle has the thickest wall because it pumps blood to the systemic circuit.
  • Question 4: The P wave on an EKG represents atrial depolarization.
  • Question 5: The QRS complex represents ventricular depolarization.
  • Question 6: A hiatal hernia can be detected on a CXR if the stomach is seen below the diaphragm — True.
  • Question 7: The right diaphragm is higher than the left diaphragm due to the liver — True.

Matching Questions

  • Question 8: The best view for a CXR to see the right middle lobe is the Right Anterior Oblique (RAO) view.
  • Question 9: An assumption that people who are of a similar background, race, physical disability or culture are the same is called a stereotyping.
  • Question 10: Labeling somebody in a way that hurts their standing in the community is called labeling.
  • Question 11: Judging somebody without really knowing much about them is called prejudice.
  • Question 12: Statement about common trends within a group, but with the recognition that further information is needed to ascertain whether the generalization applies to this particular person is a generalization.

Matching: Medical vs Patient Model

  • Question 13-18: Statements related to the medical and patient models of care are described in the questions, but the notes about which statement belongs to which model are not present.

Etiquette Based Communication Skills

  • Question 19: Three etiquette-based communication skills for patient recovery include: introduction, orienting to time and place, and lowering the bed.

Communication Loop

  • Question 20: The communication loop consists of a sender, a message, and a recipient, with feedback.

Medical Abbreviations

  • Question 21: NLMEB stands for Neutrophils, lymphocytes, monocytes, eosinophils, basophils.
  • Question 22: Neutrophils, eosinophils, and basophils are granulocytes.

Numbering of Cells
