Multiple choice

What is the recommended rate for chest compressions during CPR?

  1. 60-80 compressions per minute

  2. 100-120 compressions per minute

  3. 120-150 compressions per minute

  4. 150-180 compressions per minute
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The recommended rate for chest compressions during CPR is 100-120 compressions per minute. This rate allows for adequate blood flow to the heart and brain.

Multiple choice

  1. Heart rate

  2. Blood pressure

  3. Respiratory rate

  4. Body temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Respiratory rate is not a common vital sign monitored by health monitors. Heart rate, blood pressure, and body temperature are the most common vital signs monitored.

  2. 40-60 bpm

  3. 80-120 bpm

  4. 100-140 bpm
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

The typical range for a healthy adult's resting heart rate is 60-100 beats per minute (bpm).

Multiple choice

What is hypotension?

  1. High blood pressure

  2. Low blood pressure

  3. Heart failure

  4. Stroke
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hypotension is low blood pressure. It is a condition in which the blood pressure is consistently lower than normal.

Multiple choice

What is the difference between systolic and diastolic blood pressure?

  1. Systolic blood pressure is the pressure in the arteries when the heart beats.

  2. Diastolic blood pressure is the pressure in the arteries when the heart rests between beats.

  3. Systolic blood pressure is always higher than diastolic blood pressure.

  4. Diastolic blood pressure is always higher than systolic blood pressure.

Correct answer
Explanation

All of the above are differences between systolic and diastolic blood pressure.

Multiple choice

What is a pulse pressure?

  1. The difference between systolic and diastolic blood pressure

  2. The average blood pressure

  3. The blood pressure in the arteries

  4. The blood pressure in the veins

D Correct answer
Explanation

Tetralogy of Fallot, transposition of the great arteries, and hypoplastic left heart syndrome are all common causes of cyanosis in neonates with congenital heart defects.

Multiple choice

What is the role of echocardiography in the diagnosis of neonatal cyanosis?

  1. To confirm the presence of a congenital heart defect

  2. To assess the severity of the heart defect

  3. To guide treatment decisions

  4. All of the above
