The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:
- A. Lymphatic System
- B. Digestive System
- C. Urinary System
- D. Respiratory System
Correct Answer: A
Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.

A patient is having difficulty understanding how to properly run her glucose meter. Which of the following teaching methods would best help the patient understand how to use her instrument correctly?
- A. Give the patient an instruction booklet and encourage her to call the office if she has questions.
- B. Tell the patient to ask a healthcare provider to demonstrate how to use the instrument.
- C. Have the patient watch a video demonstrating the use of the instrument.
- D. Demonstrate the proper use of the instrument and then have the patient perform the process while still in the office.
Correct Answer: D
Rationale: By using a demonstration and performance method of patient education, the patient is offered a chance to perform a task and have learning assessed while still in the office. This ensures that any questions that the patient has can be answered immediately, and any performance issues observed by the medical assistant can also be corrected promptly. Choice A is not as effective as providing a demonstration in person, as it may not address the patient's specific learning needs or allow for immediate feedback. Choice B suggests asking a healthcare provider to demonstrate, which is similar to the correct answer but may not always be readily available in the office. Choice C, watching a video, lacks the interactive component and immediate feedback that a live demonstration provides, making it less effective in this scenario.
A patient is diagnosed with essential hypertension. Which of the following blood pressures would you expect to see in this patient prior to taking medications for the condition?
- A. 142/92
- B. 118/72
- C. 120/80
- D. 138/88
Correct Answer: A
Rationale: Before starting medications for essential hypertension, a patient would typically present with a blood pressure reading equal to or greater than 140/90. This indicates high blood pressure and is characteristic of essential hypertension. Choice A, 142/92, falls within this range, making it the correct answer. Choices B (118/72), C (120/80), and D (138/88) all have blood pressure readings that are within the normal range and would not typically be expected in a patient diagnosed with essential hypertension. Therefore, choices B, C, and D are incorrect as they do not align with the elevated blood pressure levels seen in essential hypertension.
Over a patient's lifespan, how does the pulse rate change?
- A. starts out fast and decreases as the patient ages.
- B. starts out slower and increases as the patient ages.
- C. varies from slow to fast throughout the lifespan.
- D. stays consistent from birth to death.
Correct Answer: A
Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.
Which of the following medical terms means 'surgical fixation of the stomach'?
- A. Abdominorrhaphy
- B. Gastroplasty
- C. Gastropexy
- D. Abdominorrhexis
Correct Answer: C
Rationale: The correct answer is 'Gastropexy,' which means 'surgical fixation of the stomach.' This procedure involves surgically fixing the stomach in place. 'Abdominorrhaphy' refers to suturing or repairing the abdomen, not related to fixing the stomach. 'Gastroplasty' is a surgical reconstruction of the abdomen, not specifically related to fixing the stomach. 'Abdominorrhexis' refers to the rupture or tearing of the abdomen, not a surgical fixation procedure.
A patient's body temperature has varied over the last 24 hours from 97.6 degrees F in the morning to 99 degrees F in the evening. The patient is worried that this change in temperature may indicate the beginning of a fever. Which of the following BEST explains this phenomenon?
- A. The patient definitely has a fever in the evening and should be seen by a doctor.
- B. The patient is experiencing changes related to a diurnal rhythm.
- C. The patient is more than likely taking their temperature incorrectly.
- D. The patient is experiencing changes related to fluctuating daily hormones.
Correct Answer: B
Rationale: The patient is experiencing changes related to a diurnal rhythm. Diurnal rhythm is the phenomenon of body temperature fluctuating depending on the time of day. Temperatures taken in the morning are typically lower than those taken throughout the rest of the day. Choice A is incorrect because a single elevated temperature reading in the evening does not definitively indicate a fever. Choice C is incorrect as there is no indication of incorrect temperature measurement. Choice D is incorrect as the temperature changes are not related to monthly hormones but rather to the body's natural daily rhythm.
