This cheat sheet covers the basic vital signs and patient assessment steps used in medical science and health science classes. Students need these skills to describe a patient’s condition clearly, notice changes over time, and communicate accurate information. It also helps organize what to check first during a basic patient encounter. The goal is to build safe habits, not to diagnose illness without a licensed professional.
Key Facts
- Pulse rate is measured in beats per minute, and a typical resting adult range is about 60 to 100 bpm.
- Respiratory rate is measured in breaths per minute, and a typical resting adult range is about 12 to 20 breaths per minute.
- Blood pressure is recorded as systolic/diastolic in mmHg, such as 120/80 mmHg.
- Systolic pressure is the top number and represents pressure when the heart contracts.
- Diastolic pressure is the bottom number and represents pressure when the heart relaxes between beats.
- Oxygen saturation, or SpO2, is measured as a percent, and a common normal reading is about 95% to 100% in many healthy people.
- Pain can be recorded with a 0 to 10 scale, where 0 means no pain and 10 means the worst pain imaginable.
- SAMPLE history stands for Signs and symptoms, Allergies, Medications, Past medical history, Last oral intake, and Events leading up to the problem.
Vocabulary
- Vital signs
- Measurements such as pulse, respiratory rate, blood pressure, temperature, and oxygen saturation that give a quick picture of body function.
- Pulse
- The rhythmic pressure wave felt in an artery when the heart pumps blood.
- Respiratory rate
- The number of breaths a person takes in one minute.
- Blood pressure
- The force of blood pushing against artery walls, written as systolic pressure over diastolic pressure.
- Oxygen saturation
- The percentage of hemoglobin in the blood that is carrying oxygen, often measured with a pulse oximeter.
- SAMPLE history
- A structured set of questions used to gather important patient history during an assessment.
Common Mistakes to Avoid
- Counting pulse for only a few seconds and guessing the rest is wrong because an irregular rhythm can make the final beats per minute inaccurate.
- Recording blood pressure without units is wrong because 120/80 must be labeled in mmHg to show the measurement scale.
- Ignoring respiratory rate is wrong because breathing changes can be an early sign of distress even when pulse and blood pressure look normal.
- Treating one vital sign as a diagnosis is wrong because vital signs must be interpreted together with symptoms, history, and the situation.
- Asking leading patient history questions is wrong because it can influence the patient’s answer and reduce accuracy.
Practice Questions
- 1 A student counts 18 breaths in 60 seconds. What is the respiratory rate, and is it within the typical adult resting range?
- 2 A patient’s blood pressure is 118/76 mmHg. Identify the systolic pressure and the diastolic pressure.
- 3 A pulse is counted for 30 seconds and the count is 38 beats. What is the pulse rate in beats per minute?
- 4 Why should a medical student record symptoms, vital signs, and SAMPLE history together instead of relying on only one measurement?
