All Questions

Question 1

Free

Multiple Choice

A nurse explains the function of the alveoli to a patient with respiratory problems. Which information about the alveoli's function will the nurse share with the patient?

Choose correct answer/s

Carries out gas exchange

Regulates tidal volume

Produces hemoglobin

Stores oxygen

Check answer

Question 2

Free

Multiple Choice

A nurse auscultates heart sounds. When the nurse hears S?, which valves is the nurse hearing close?

Choose correct answer/s

Aortic and mitral

Mitral and tricuspid

Aortic and pulmonic

Mitral and pulmonic

Check answer

Question 3

Free

Multiple Choice

The nurse is teaching about the process of exchanging gases through the alveolar capillary membrane. Which term will the nurse use to describe this process?

Choose correct answer/s

Ventilation

Surfactant

Perfusion

Diffusion

Check answer

Question 4

Free

Multiple Choice

A nurse is caring for a patient who was in a motor vehicle accident that resulted in cervical trauma to C4. Which assessment is the priority?

Choose correct answer/s

Pulse

Respirations

Temperature

Blood pressure

Check answer

Question 5

Free

Multiple Choice

The patient is breathing normally. Which process does the nurse consider is working properly when the patient inspires?

Choose correct answer/s

Stimulation of chemical receptors in the aorta

Reduction of arterial oxygen saturation levels

Requirement of elastic recoil lung properties

Enhancement of accessory muscle usage

Check answer

Question 6

Multiple Choice

The home health nurse recommends that a patient with respiratory problems install a carbon monoxide detector in the home. What is the rationale for the nurse's action?

Choose correct answer/s

Carbon monoxide detectors are required by law in the home.

Carbon monoxide tightly binds to hemoglobin, causing hypoxia.

Carbon monoxide signals the cerebral cortex to cease ventilations.

Carbon monoxide combines with oxygen in the body and produces a deadly toxin.

Question 7

Multiple Choice

While performing an assessment, the nurse hears crackles in the patient's lung fields. The nurse also learns that the patient is sleeping on three pillows to help with the difficulty breathing during the night. Which condition will the nurse most likely observe written in the patient's medical record?

Choose correct answer/s

Atrial fibrillation

Myocardial ischemia

Left-sided heart failure

Right-sided heart failure

To unlock the question

Question 8

Multiple Choice

A patient has a myocardial infarction. On which primary blood vessel will the nurse focus care to reduce ischemia?

Choose correct answer/s

Superior vena cava

Pulmonary artery

Coronary artery

Carotid artery

To unlock the question

Question 9

Multiple Choice

A nurse is teaching a health class about the heart. Which information from the class members indicates teaching by the nurse is successful for the flow of blood through the heart, starting in the right atrium?

Choose correct answer/s

Right ventricle, left ventricle, left atrium

Left atrium, right ventricle, left ventricle

Right ventricle, left atrium, left ventricle

Left atrium, left ventricle, right ventricle

To unlock the question

Question 10

Multiple Choice

The nurse suspects the patient has increased afterload. Which piece of equipment should the nurse obtain to determine the presence of this condition?

Choose correct answer/s

Pulse oximeter

Oxygen cannula

Blood pressure cuff

Yankauer suction tip catheter

To unlock the question

Question 11

Multiple Choice

A patient has heart failure and cardiac output is decreased. Which formula can the nurse use to calculate cardiac output?

Choose correct answer/s

Myocardial contractility * Myocardial blood flow

Ventricular filling time/Diastolic filling time

Stroke volume * Heart rate

Preload/Afterload

To unlock the question

Question 12

Multiple Choice

A patient's heart rate increased from 94 to 164 beats/min. What will the nurse expect?

Choose correct answer/s

Increase in diastolic filling time

Decrease in hemoglobin level

Decrease in cardiac output

Increase in stroke volume

To unlock the question

Question 13

Multiple Choice

The nurse is careful to monitor a patient's cardiac output. Which goal is the nurse trying to achieve?

Choose correct answer/s

To determine peripheral extremity circulation

To determine oxygenation requirements

To determine cardiac dysrhythmias

To determine ventilation status

To unlock the question

Question 14

Multiple Choice

A nurse is caring for a group of patients. Which patient should the nurse see first?

Choose correct answer/s

A patient with hypercapnia wearing an oxygen mask

A patient with a chest tube ambulating with the chest tube unclamped

A patient with thick secretions being tracheal suctioned first and then orally

A patient with a new tracheostomy and tracheostomy obturator at bedside

To unlock the question

Question 15

To unlock the question

Question 19

Multiple Choice

A nurse teaches a patient about atelectasis. Which statement by the patient indicates an understanding of atelectasis?

Choose correct answer/s

"Atelectasis affects only those with chronic conditions such as emphysema."

"It is important to do breathing exercises every hour to prevent atelectasis."

"If I develop atelectasis, I will need a chest tube to drain excess fluid."

"Hyperventilation will open up my alveoli, preventing atelectasis."
