Free ARRT Patient Care Questions and Answers — Questions and Answers

Question 1: When a patient arrives for a radiologic evaluation, an intravenous contrast injection is necessary. What is the creatinine normal range?

8–15 mg/100 milliliters
0–0.4 mg/100 milliliters
0.6–1.5 mg per 100 milliliters (Correct answer)
2.0–4.0 mg per milliliter

Correct answer: 0.6–1.5 mg per 100 milliliters

This is the creatinine normal range. Increasing your exercise will raise your levels of creatinine. Low creatinine can be hazardous and dangerous. Lower creatinine levels can be caused by liver and muscle diseases. Increased concentrations may have greater detrimental effects. High blood pressure, nausea, and vomiting are among the symptoms. Renal failure and dehydration are two symptoms associated with elevated creatinine.

Question 2: If a patient has low blood pressure and is experiencing a syncopal episode, how should they be positioned?

Partial Fowler's
Sims (Correct answer)
Lateral recumbent on the right
Trendelenburg

Correct answer: Sims

Another name for the Sims position is the recovery position. The patient is laid on their left side in a recumbent position. This keeps the patient's airway open and lessens the chance of aspiration. The right lateral recumbent position would actually enhance the patient's risk of aspiration if they were to vomit during the episode because their right main stem bronchus is longer and straighter than their left. The head being lower than the feet is known as the Trendelenburg position, and it is not suitable for patient management in this situation since it raises the risk of aspiration or airway obstruction. Since the head is higher than the feet in the semi-Fowler position, blood flow to the brain is more challenging in this situation.

Question 3: Think of a patient who has a long fractured bone. Which of the following approaches to moving the injured extremity—for example, positioning the image receptor beneath the injured extremity—is the most suitable for imaging purposes?

Adjust the end in the direction closest to the fracture.
Adjust the end in a way that is not close to the fracture.
Directly manipulate the fracture location.
Alter the extremity's two ends simultaneously and cooperatively. (Correct answer)

Correct answer: Alter the extremity's two ends simultaneously and cooperatively.

In this case, the radiographer should move the extremities simultaneously and cooperatively. In addition to ensuring that the fracture fragments maintain their correct anatomical alignment, this will lessen patient discomfort. In this case, manipulating just one extremity's end would make the patient more uncomfortable and could make the fracture more unstable. In this case, manipulating just one extremity's end would make the patient more uncomfortable and could make the fracture more unstable. The patient would suffer greatly by manipulation of the fracture site, and the alignment of the fracture pieces would be jeopardized.

Question 4: Providing information on a patient's kidney function, which of the following is a crucial lab value that needs to be confirmed before intravenous iodinated contrast media is administered?

The creatinine (Correct answer)
Blood globin
AFT, or aspartate aminotransferase
WBC, or white blood cell count

Correct answer: The creatinine

One byproduct of muscle metabolism is creatinine. It is crucial to keep an eye on kidney function, since elevated creatinine levels may be a sign of compromised renal health. Iodinated contrast media administration may result in renal failure in a patient with a high blood creatinine level. The WBC is a measurement of the patient's blood's white blood cell count. This result does not indicate normal kidney function, although being vital in the battle against infection. The iron-containing protein in the blood that is in charge of carrying oxygen around is measured by something called hemoglobin. Although it is essential for the body's appropriate physiologic function, kidney function is unrelated to it, hence it is not a critical parameter for the administration of IV contrast.

Question 5: Which of these describes a manual respirator type?

membranous oxygenation outside the body (ECMO)
Positive airway pressure that is continuous (CPAP)
Ambu (Correct answer)
a mechanical ventilator

Correct answer: Ambu

An Ambu bag is a type of manual respirator that requires periodic squeezing of the bag to help sustain airflow, usually every few seconds. Before a patient is put on a mechanical ventilator, they are typically utilized to maintain oxygenation. Patients for whom the heart and lungs are unable to complete gas exchange effectively can receive enough oxygenation with the use of an artificial lung provided by ECMO devices. Mechanical ventilators let people breathe after being intubated so that their lungs can heal after a serious sickness or injury. In order to help avoid airway collapse in patients with sleep apnea, continuous positive airway pressure (CPAP) devices are used.

Question 6: A patient is left unattended on the exam table by RT Jones. Most likely, this is an illustration of:

Battery
Beneficence
Negligence (Correct answer)
Charismatic

Correct answer: Negligence

Negligent people don't act in ways that a reasonable person would in a comparable circumstance. One action that can be considered negligent is leaving a patient unattended on the examination table. Behaving in a way that would help others is referred to as being benevolent, and it is an ideal that all medical practitioners ought to pursue. The term ""battery"" refers to using force without authorization. Applying firm patient restraints for immobilization without permission or a doctor's order is one instance in radiology. Publicating words that have the potential to harm someone's reputation is known as libel. Adding libelous information to a patient's electronic medical record (EMR) is one instance.

Question 7: A CAT scan of the patient's head is being performed. The patient reports feeling queasy and having trouble breathing after receiving a contrast injection. Which kind of shock is the patient going through?

Neural
Septic
Anaphylactic (Correct answer)
Cardiogenic

Correct answer: Anaphylactic

Anaphylaxis shock is a serious allergic reaction that can be fatal. Breathing difficulties, nausea, vomiting, and low blood pressure are possible side effects. The treatment for anaphylaxis is an injection of epinephrine. Infections are the cause of septic shock. Cardiogenic shock will result from cardiac issues. Your nervous system injury results in neurogenic shock.

Question 8: What is the purpose of the x-ray tube's housing?

aids in the creation of images
maintains warmth within the glass envelope
promotes electric shock
reduces the risk of radiation leaks (Correct answer)

Correct answer: reduces the risk of radiation leaks

Reducing radiation leakage is one of the housing's main purposes. Lead lining within the x-ray tube reduces leakage. Glass borosilicate is used to make glass tube envelopes. This aids in regulating the tube's internal heat. The heat from the glass tube is not retained by the housing. The x-ray tube's casing serves as protection from electrical shock. Image production is unaffected by the casing surrounding the x-ray tube.

Question 9: What is the term for the reddening of irritated skin caused by radiation?

Petiae
Eczema
Psoriasis
Erythema (Correct answer)

Correct answer: Erythema

The redness of the skin induced by increased capillary blow flow or congestion in the lower layers of the skin is known as erythema. One common side effect of radiation therapy is erythema. The onset of psoriasis is beneath the skin. It is an immune system chronic illness. Petechiae are tiny, spherical lesions that develop on skin after bleeding. Common skin conditions like eczema are characterized by irritated and itchy skin areas.

Question 10: When a patient is on their back and their head is lower than their feet, what position is that?

Trendelenburg (Correct answer)
Fowler's
Lateral Reclining
Sim's

Correct answer: Trendelenburg

When a patient lies supine with their head lower than their feet, it is known as a Trendelenburg posture. The inclination ranges from 15 to 30 degrees. When a patient is sitting up in bed, they have Fowler's disease. The Sim's posture is achieved when a patient is on their side with their knee and thigh drawn upward toward the chest. A patient in the lateral recumbent position is said to be such.

Question 11: What are the post-examination instructions for patients receiving a barium enema?

Consume a lot of liquids. (Correct answer)
Keep no track of your bowel motions.
Avoid hydration for six hours.
Refrain from using a laxative.

Correct answer: Consume a lot of liquids.

An x-ray check of the large intestine used to find any abnormalities or alterations is called a barium enema. It's advised to stay hydrated for the next six hours following the examination. This facilitates the barium's passage through the intestines. Laxatives should be used by patients to help ease intestinal pressure. Keeping an eye on bowel movements is crucial. For up to 72 hours following a procedure, light-colored bowel motions may occur; these should be monitored for blood.
