1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. Penny Thornton has had a stroke, or CVA, and is having difficulty eating on her own. Soon, she will be getting some assistive devices for eating meals. Which healthcare worker will be providing Penny with these assistive devices?

• A. A physical therapist
• B. A speech therapist
• C. A social worker
• D. An occupational therapist

Correct answer: D

Rationale: An occupational therapist is the healthcare professional responsible for assessing the needs of individuals, like Penny, regarding assistive devices that aid them in their daily activities. In this case, assistive devices for eating, such as weighted plates and specialized utensils, are crucial for helping Penny regain independence in feeding herself. Physical therapists focus more on mobility and movement, speech therapists on communication and swallowing disorders, and social workers on providing emotional and social support. Therefore, the correct choice is the occupational therapist as they specialize in activities of daily living and promoting independence.

3. 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.

4. Where is the duodenum located in the digestive system?

• A. It is the first part of the small intestine, located immediately after the stomach.
• B. It is the section of the digestive system where the gall bladder delivers bile.
• C. It is the section of the small intestine where the pancreas delivers digestive juices.
• D. None of the above.

Correct answer: D

Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.

5. When assessing a pulse, what should be noted?

• A. Rate
• B. Rate and quality
• C. Rate, quality, and fullness
• D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.
