ATI Anatomy and Physiology Online Practice
1. The activities of an anatomist consist of ______, whereas those of a physiologist consist of _____.
- A. observing body parts; studying functions of body parts
- B. conducting experiments; making microscopic examinations
- C. studying molecules; observing forms of the body parts
- D. sketching; dissecting
Correct answer: observing body parts; studying functions of body parts
Rationale: An anatomist focuses on observing the structure and morphology of body parts, such as organs, tissues, and cells, to understand their organization. On the other hand, a physiologist is more concerned with studying the functions and processes of these body parts, including how they work individually and together to maintain homeostasis. Therefore, the correct answer is 'observing body parts; studying functions of body parts.' Choices B, C, and D are incorrect as they do not accurately reflect the primary activities of anatomists and physiologists.
2. A nurse is preparing a client for surgery. The client refuses to remove a religious medal. What is the nurse's best response?
- A. Ask the family to remove the medal
- B. Place the medal in a safe place for the client
- C. Allow the client to keep the medal during surgery
- D. Inform the client that the medal must be removed
Correct answer: C
Rationale: The correct answer is to allow the client to keep the medal during surgery. Clients may retain religious medals or jewelry during surgery if it does not interfere with the procedure. Asking the family to remove the medal (Choice A) may not be respecting the client's wishes. Placing the medal in a safe place for the client (Choice B) may cause distress to the client who wants to keep it. Informing the client that the medal must be removed (Choice D) disregards the client's beliefs and preferences.
3. A nurse is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?
- A. BUN 8 mg/dL
- B. Hgb 15 g/dL
- C. Creatinine 0.8 mg/dL
- D. Sodium 140 mEq/L
Correct answer: A
Rationale: A BUN level of 8 mg/dL is indicative of fluid volume excess, which is common in clients with heart failure.
4. A condition that is conducive to the development of dental caries is said to be _____.
- A. periodontal
- B. cariogenic
- C. gingival
- D. bacteriophilic
Correct answer: B
Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.
5. Which term refers to the relaxation phase of the heart, during which the chambers fill with blood?
- A. Diastole
- B. Systole
- C. Refractoriness
- D. Automaticity
Correct answer: A
Rationale: The correct answer is A, Diastole. Diastole is the phase of the cardiac cycle when the heart muscles relax, allowing the chambers to fill with blood. Choice B, Systole, is incorrect as systole is the contraction phase of the heart when blood is pumped out of the chambers. Choice C, Refractoriness, refers to a period during which the heart muscle is unresponsive to stimuli. Choice D, Automaticity, relates to the heart's ability to generate its own electrical impulses.
