Nursing Elites

1. 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.

2. 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.

3. What is the anatomic structure located in the middle of the heart that separates the right and left ventricles?

• A. Septum
• B. Sputum
• C. Separator
• D. None of the above

Correct answer: A

Rationale: The correct answer is the septum. The septum is a structure located in the middle of the heart that separates the right and left ventricles. It plays a crucial role in maintaining the separation between the two ventricles to ensure efficient blood flow. The other choices, 'Sputum' and 'Separator,' are incorrect as they do not refer to the anatomic structure in the heart that serves this specific function. 'Sputum' is a term used to describe phlegm or mucus, not an anatomical structure, and 'Separator' is a generic term that does not specifically identify the cardiac structure mentioned in the question.

4. When assisting a client with shampooing his hair while he is still in bed, a nurse raises the bed to approximately the level of her waist. What is the rationale for this action?

• A. To prevent shampoo from getting into the client's eyes
• B. To allow excess water to run off the edge of the bed
• C. To decrease strain on the nurse's back
• D. To prevent the client's hair from developing tangles

Correct answer: C

Rationale: Raising the bed to the level of the nurse's waist while assisting a client with shampooing in bed is done to reduce strain on the nurse's back. This adjustment ensures that the nurse can work comfortably without excessive bending or stooping, thus preventing back injuries. Choices A, B, and D are incorrect. While preventing shampoo from getting into the client's eyes, allowing excess water to run off the bed, and preventing hair tangles are important considerations, the primary rationale for raising the bed is to prioritize the nurse's ergonomic safety and prevent musculoskeletal strain.

5. When assessing a patient's pulse, which of the following characteristics would the nurse also notice?

• A. Force
• B. Pallor
• C. Capillary refill time
• D. Timing in the cardiac cycle

Correct answer: A

Rationale: When assessing a patient's pulse, the nurse should observe characteristics such as rate, rhythm, and force. Force refers to the strength or amplitude of the pulse, which provides important information about cardiac output. Pallor is the paleness of the skin and is not directly related to pulse assessment. Capillary refill time is used to assess peripheral perfusion and is not specifically part of pulse assessment. Timing in the cardiac cycle is a broader concept and not a characteristic directly assessed during a pulse examination. Therefore, choice A, 'Force,' is the correct answer as it aligns with the standard parameters evaluated during pulse assessment.
