Free CCP-C Exam Flashcards

The receiver repeats the instruction, and the sender confirms it or corrects the repeat-back. This catches errors such as a misheard drug concentration before anyone acts.

Sudden braking or a collision can turn loose equipment into projectiles. Use the vehicle’s approved mounts or restraints so equipment stays in place and remains available for care.

Include movement to and from the ambulance, the road trip, and a reserve for delays or rising oxygen demand. Use the actual oxygen requirements of the delivery device when estimating supply.

Continuous waveform capnography. A sustained exhaled carbon dioxide waveform supports tracheal placement, and ongoing monitoring can alert the crew to displacement or disconnection.

Neuromuscular blockade stops skeletal muscle movement without providing unconsciousness or pain relief. Use a sedative-hypnotic induction agent when giving a paralytic for intubation.

It increases the oxygen reserve in the lungs and can delay desaturation during apnea. This gives the crew more time to secure the airway before hypoxemia develops.

Increased resistance to airflow, as with a kinked tube, secretions, or bronchospasm. Compare at similar settings in a passive patient so the pressures reflect respiratory mechanics.

Through the neck stoma. The trachea ends at the stoma, and the mouth and nose no longer connect to the lungs.

A cuff manometer measures it directly. Squeezing the pilot balloon gives an unreliable estimate, so a cuff can feel adequate while its pressure is too low or too high.

Insulin deficiency and acidemia shift potassium out of cells while osmotic diuresis depletes body stores. Serum potassium can fall during treatment as insulin moves it back into cells.

Subtract chloride and bicarbonate from sodium (Na⁺ − [Cl⁻ + HCO₃⁻]). A raised gap suggests an increase in unmeasured anions, such as those from lactate or ketoacids.

It reads falsely high because the fluid column adds hydrostatic pressure. Re-level the transducer to the designated reference point after repositioning the patient or monitor.

Serial measurements show whether an elevated lactate is falling. Interpret the trend alongside other perfusion findings, such as capillary refill, because lactate can rise for several reasons.

Tall, peaked T waves are one clue. Conduction can also slow as potassium rises, and the ECG can look relatively normal even with clinically important hyperkalemia.

Synchronized cardioversion. The device times the shock to the QRS complex to reduce the risk of delivering energy during ventricular repolarization.

Look for a perfusing beat with each paced QRS, such as a matching arterial pressure upstroke or pulse. Electrical capture is ventricular depolarization. Mechanical capture is the resulting perfusing contraction.

It inflates at the start of diastole to augment aortic diastolic pressure and deflates just before systole to reduce left ventricular afterload.

Continuous pump flow can produce very little pulse pressure despite ongoing circulation. Use signs of perfusion and a Doppler or arterial pressure when available to assess circulation.

The heart cannot deliver enough blood flow to meet tissue needs. Look for hypoperfusion, such as cool extremities, altered mentation, or low urine output, in the setting of cardiac dysfunction.

At least 65 mm Hg. Avoiding hypotension helps preserve blood flow to the brain and other organs after cardiac arrest.

65 mm Hg. Subtract intracranial pressure from mean arterial pressure. A fall in blood pressure or a rise in intracranial pressure reduces this gradient.

Drainage depends on the height of the collection system relative to the ventricles. Re-level to the ordered reference and height so a position change does not alter drainage or distort the pressure reading.

It is the last time the patient was known to be at their neurologic baseline. For someone who wakes with symptoms, it may be the time they were last observed well before sleep.

At five minutes. The same threshold applies to repeated convulsions over that interval without recovery of consciousness between them.

Low carbon dioxide constricts cerebral vessels and can reduce blood flow to injured brain tissue. Brief controlled hyperventilation is reserved for signs of active, imminent herniation under protocol.

Predicted body weight, based on height and sex. It estimates lung size, so using actual weight in a patient with obesity can lead to an excessive tidal volume.

Expiratory flow repeatedly fails to return to zero before the next breath. Incomplete exhalation traps gas and can raise intrathoracic pressure enough to impair venous return.

Upright and below the chest tube insertion site. This helps prevent backflow and preserves the function of the drainage system.

200 mm Hg. Divide the arterial oxygen pressure by FiO₂ as a fraction (80 ÷ 0.40). A lower ratio indicates worse oxygenation relative to the oxygen delivered.

Acute or acute-on-chronic respiratory acidosis from carbon dioxide retention. In an appropriate patient, bilevel support improves ventilation and can reduce the need for intubation.

A conventional two-wavelength oximeter cannot reliably distinguish carboxyhemoglobin from oxyhemoglobin. Blood co-oximetry can measure carboxyhemoglobin when the exposure history raises concern.

Marked central nervous system dysfunction, such as delirium, ataxia, or seizures, with a high core temperature. Heat stroke can occur even while the patient is sweating.

Hypothermia, acidosis, and coagulopathy. They reinforce one another during hemorrhagic shock and make bleeding harder to control.

Citrate in blood products binds free calcium. Falling ionized calcium can impair clotting and cardiac function, so it is an important value to monitor during major resuscitation.

Count partial-thickness and full-thickness burns. Superficial erythema alone is excluded from the estimate used for burn severity and resuscitation planning.

Rigid eschar can constrict swollen tissue and reduce distal blood flow. Escharotomy releases that external restriction when indicated.

The focused ultrasound detects free fluid in specific views. It can miss early or small-volume bleeding and does not reliably evaluate the retroperitoneum.

Airway swelling and impaired gas exchange can develop after the initial assessment. A patient with significant smoke exposure may deteriorate even when the skin burns appear limited.

Maternal blood can collect behind the separating placenta. Pain, uterine tenderness, or signs of shock may be more revealing than visible blood loss.

Hemolysis, elevated liver enzymes, and a low platelet count. In a pregnant or postpartum patient, this combination suggests a serious hypertensive complication that requires urgent obstetric evaluation.

A rising heart rate. When the heart rate fails to rise, reassess ventilation for problems such as a mask leak or airway obstruction.

Prostaglandin E₁ keeps the ductus arteriosus open to support pulmonary or systemic blood flow until definitive care. Apnea is a known risk, so the transport team needs ventilatory support immediately available.

Tachycardia and vasoconstriction can temporarily maintain pressure. Weak peripheral pulses, delayed capillary refill, or altered behavior may reveal impaired perfusion before hypotension appears.

Kilograms. Use a measured weight when feasible. Treating the numerical weight in pounds as kilograms yields about 2.2 times the intended dose before applying any dose cap.

It signals more airway obstruction than stridor heard only with agitation. Interpret it alongside retractions, air entry, and mental status because stridor can get quieter as respiratory failure develops.

Cerebral injury. Worsening mental status with unexplained heart-rate deceleration during pediatric diabetic ketoacidosis warrants urgent reassessment.

Each component has its own safe working load. For a loading system rated for the full load, include the patient, cot, and attached equipment. The transfer must fit the limits of both components.

Beta blockade can blunt the normal heart-rate response to blood loss. Compare the patient’s pressure and perfusion with their baseline and reassess as the clinical picture changes.

Examine the conditions that made the event possible and the behavior involved. A slip calls for support and system improvement, an at-risk choice calls for coaching, and reckless disregard calls for accountability.

It governs whether resuscitation is attempted if the patient arrests. Other treatments follow the patient’s goals and separate orders. Verify that the order applies to the transfer under local requirements.
