If a patient experiences symptoms with low blood pressure, it’s important to investigate the underlying cause.
Which of these is a common cause of hospital-acquired infections?
Urinary catheters are tubes inserted to help patients urinate, but if not managed properly, they can introduce bacteria into the bladder, leading to infections called catheter-associated urinary tract infections (CAUTIs). These infections are one of the most frequent hospital-acquired infections in the United States. Good hand hygiene and careful catheter care are essential to prevent them.
A patient’s temperature reads 102.5°F (39.2°C). How would you document this finding?
A body temperature over 100.4°F is considered a fever in adults, which signals that the body is likely fighting an infection or illness. Documenting as "fever" helps guide healthcare providers in monitoring and treating the patient's condition. Persistent high fevers may require further evaluation to rule out serious underlying causes.
Which position is best for a patient experiencing difficulty breathing?
High Fowler’s position, where the patient sits upright at a 60- to 90-degree angle, helps gravity assist the expansion of the chest and lungs, making breathing easier. This position is commonly used for patients with respiratory distress, heart problems, or after certain surgeries. It also reduces pressure on the abdomen, which can further ease breathing for those in distress.
A patient is experiencing chest pain and shortness of breath. What is your first priority?
Ensuring a patient's airway, breathing, and circulation—often called the ABCs—is the first priority in any medical emergency, as these are critical for sustaining life. If any of these are compromised, immediate intervention is necessary before addressing other symptoms. This foundational approach is taught in Basic Life Support and is highlighted in emergency protocols around the world.
What is the normal range for an adult’s resting heart rate?
A normal adult resting heart rate falls between 60-100 beats per minute, reflecting the typical range needed to maintain healthy blood flow without overworking the heart. Athletes often have heart rates below 60 due to better cardiovascular fitness, but rates consistently above or below this range can signal health problems. Monitoring heart rate is a simple but important part of assessing overall heart health.

What is the largest artery in the human body?
The aorta is the main and largest artery, carrying oxygen-rich blood from the left ventricle of the heart to the rest of the body. It is about the diameter of a garden hose and branches into smaller arteries that supply blood to all organs and tissues. Damage or disease of the aorta, such as an aneurysm, can be life-threatening due to its crucial role.
A nurse notes a patient’s respiratory rate is 28 breaths per minute. This is best described as:
Tachypnea means abnormally rapid breathing, and a normal adult respiratory rate is generally 12 to 20 breaths per minute. Anything above that range, like 28 breaths per minute, signals tachypnea and may indicate fever, anxiety, or underlying health problems. Early detection of tachypnea is important for preventing complications in patients.
Which bone is located in the upper arm and commonly fractured in falls?
The humerus is the long bone that runs from your shoulder to your elbow and is the only bone in the upper arm. It's commonly fractured when people try to break a fall with their hand, transferring force up the arm. Interestingly, the term "funny bone" refers to the area around the humerus where the ulnar nerve runs, causing a tingling sensation when bumped.
What is the primary function of platelets in the blood?
Platelets, also called thrombocytes, rush to the site of a blood vessel injury and stick together to form a plug, which is the first step in stopping bleeding. Without platelets, even small cuts could become dangerous because the blood would not clot properly. Interestingly, platelets live only about 7-10 days in the bloodstream before being replaced by new ones from the bone marrow.
What is the medical term for difficulty breathing?
Dyspnea is the medical term used to describe the sensation of shortness of breath or difficulty breathing, a common symptom in many heart and lung conditions. It comes from Greek roots meaning "bad breathing." Recognizing dyspnea is important in healthcare because it can signal serious underlying problems like asthma, heart failure, or pneumonia.
You are caring for a patient with a cast. What is an early sign of impaired circulation in the limb?
Pale, cool skin and tingling are early signs that blood flow to the limb is being restricted, which can happen if a cast is too tight. Catching these symptoms early is vital to prevent serious complications, such as tissue damage or nerve injury. Nurses are trained to check for changes in color, temperature, and sensation to catch circulation issues before they become emergencies.
Which electrolyte imbalance is most likely to cause dangerous heart rhythms?
High potassium levels (hyperkalemia) can disrupt the electrical activity of the heart, leading to life-threatening arrhythmias. Potassium is crucial for normal heart muscle function, and even slight imbalances can cause serious cardiac effects. Quick correction of hyperkalemia is a medical emergency because it can result in sudden cardiac arrest.
Which part of the brain controls balance and coordination?
