ARRT Practice Questions for Patient Care Questions
Question 1 of 5
Tachypnea occurs when respirations are more than ___ breaths per minute.
Correct Answer: C
Rationale: The correct answer is C (20). Tachypnea is defined as rapid breathing, typically more than 20 breaths per minute in adults. This is a critical respiratory parameter indicating an increased breathing rate. Choices A, B, and D are below the typical threshold for tachypnea, hence they are incorrect. It is essential to recognize the correct definition of tachypnea to accurately identify abnormal respiratory rates.
Question 2 of 5
A clean-catch specimen is also called a __________ specimen because the first and last voiding are not included in the urine sample.
Correct Answer: D
Rationale: The correct answer is D: Midstream. A clean-catch specimen, also known as a midstream specimen, is collected after the initial stream of urine to avoid contamination from the urethra or external genitalia. This method helps ensure a more accurate sample for testing. A: Contaminated - Incorrect. This term implies impurity, which is the opposite of what a clean-catch specimen aims to achieve. B: Cleansing - Incorrect. While cleanliness is important in specimen collection, this term does not specifically refer to the methodology of a clean-catch specimen. C: Stop and start - Incorrect. This term does not accurately describe the process of collecting a clean-catch specimen, which involves a continuous flow after the initial voiding.
Question 3 of 5
A _______________ burn affects the epidermis,dermis and underlying tissue.
Correct Answer: D
Rationale: The correct answer is D: Third-degree burn. A third-degree burn affects the epidermis, dermis, and underlying tissue, resulting in damage to all layers of the skin. This type of burn is the most severe, causing significant tissue destruction and requiring medical attention. A: Second-degree burn only affects the epidermis and dermis, not the underlying tissue. B: First-degree burn only affects the outer layer of the skin (epidermis). C: Partial-thickness burn is a general term that can refer to both first- and second-degree burns, but it does not specifically indicate damage to the underlying tissue like a third-degree burn does.
Question 4 of 5
A benefit from the regular use of deep-breathing exercises is
Correct Answer: C
Rationale: The correct answer is C: Increased lung capacity. Deep-breathing exercises involve inhaling deeply, which helps to expand the lungs and improve their capacity. This allows for more efficient oxygen exchange and can improve overall respiratory function. Increased mucus in the respiratory system (A) is not a benefit of deep-breathing exercises and can actually be a sign of respiratory issues. Decreased salivary production (B) is unrelated to deep-breathing exercises. Decreased oxygen levels (D) would be counterproductive to the goal of deep-breathing exercises, which aim to improve oxygen intake.
Question 5 of 5
Which of the following is a function of the musculoskeletal system?
Correct Answer: C
Rationale: The correct answer is C: Stores calcium and phosphorus. The musculoskeletal system plays a crucial role in storing minerals like calcium and phosphorus, which are essential for bone health and muscle function. Bones act as a reservoir for these minerals, releasing them when needed for various bodily functions. This function helps maintain the body's mineral balance and supports overall skeletal strength. Explanation for why the other choices are incorrect: A: Storing vitamin D is primarily done by adipose tissue and the liver, not the musculoskeletal system. B: Supplying oxygen to cells is the role of the respiratory and circulatory systems, not the musculoskeletal system. D: Transporting antibodies to cells is the function of the immune system, involving the lymphatic system and blood circulation, not the musculoskeletal system.
