Nursing Elites

1. What does the term 'Afferent Nerve' mean?

• A. Carrying an impulse to the brain
• B. Carrying an impulse away from the brain
• C. Carrying impulses to the motor neurons of the appendicular muscles
• D. None of the above

Correct answer: A

Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'

2. When taking blood pressures on a variety of people at a health fair, what should the nurse keep in mind?

• A. After menopause, blood pressure readings in women are usually higher than those taken in men.
• B. The blood pressure of an African-American adult is usually higher than that of a non-Hispanic White adult of the same age.
• C. Blood pressure measurements in people who are overweight are usually higher than those of people who are at a normal weight.
• D. A teenager's blood pressure reading may be lower than that of an adult.

Correct answer: B

Rationale: When assessing blood pressures, it is important to consider that the blood pressure of African-American adults is typically higher than that of non-Hispanic White adults of the same age. This is significant as Black individuals in the United States have a higher prevalence of hypertension compared to other groups. Blood pressure readings in women are generally higher than in men after menopause. Additionally, blood pressure measurements in overweight individuals are typically higher than those in individuals of normal weight. While teenagers may have lower blood pressure readings than adults, it is crucial to recognize the trend of a gradual rise in blood pressure throughout childhood and into adulthood. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they do not reflect the typical blood pressure differences observed in various populations.

3. A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?

• A. Blood pressure readings are taken in both arms and thighs.
• B. The patient is assisted to a lying position, and their blood pressure is taken.
• C. The patient's blood pressure is recorded in lying, sitting, and standing positions.
• D. The patient's blood pressure is recorded in lying and sitting positions; these numbers are then averaged to obtain a mean blood pressure.

Correct answer: C

Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure. Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.

4. When examining an infant, which area should the nurse examine first?

• A. Ear
• B. Nose
• C. Throat
• D. Abdomen

Correct answer: D

Rationale: When examining an infant, the nurse should start by examining the least-distressing areas first before moving on to more invasive areas. The abdomen is typically the least distressing area to examine, so it should be assessed first. Examining the eye, ear, nose, and throat are considered more invasive and should be saved for last. Therefore, the correct choice is to examine the abdomen first to ensure a comfortable and less distressing examination process for the infant. Choices A, B, and C (Ear, Nose, Throat) are more invasive areas and should be examined after the abdomen.

5. What is the MOST ACCURATE statement regarding the ESR test?

• A. The results are diagnostic for certain conditions.
• B. Abnormal results are indicative of a potentially fatal illness.
• C. Abnormal results should be followed by additional testing.
• D. Results are reported in millimeters per hour.

Correct answer: C

Rationale: The erythrocyte sedimentation rate (ESR) is a non-specific screening test for inflammation in the body. It is not used as a definitive diagnostic tool for specific conditions. When ESR results are abnormal, they indicate the presence of inflammation, which can be caused by various reasons. Therefore, abnormal results should be followed by additional testing to determine the underlying cause. The ESR test measures the rate at which red blood cells settle in a vertical tube over the span of one hour, and results are reported in millimeters per hour. Choice A is incorrect because ESR results are not solely diagnostic for any specific condition. Choice B is incorrect as abnormal ESR results do not directly indicate a potentially fatal illness without further investigation. Choice D is incorrect as the results are reported in millimeters per hour, not per minute.
