Nursing Elites

1. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.

2. After a class on culture and ethnicity, the new graduate nurse reflects a correct understanding of the concept of ethnicity with which statement?

• A. "Ethnicity is dynamic and ever-changing."?
• B. "Ethnicity is the belief in a higher power."?
• C. "Ethnicity pertains to a social group that may possess shared traits such as religion and language."?
• D. "Ethnicity is learned from birth through the processes of language acquisition and socialization."?

Correct answer: C

Rationale: Ethnicity pertains to a social group that may possess shared traits such as common geographic origin, migratory status, religion, language, values, traditions, or symbols and food preferences. Culture is dynamic, ever-changing, and learned from birth through the processes of language acquisition and socialization. Religion is the belief in a higher power. Ethnicity pertains to a social group within the social system that claims to have variable traits, such as a common geographic origin, migratory status, religion, race, language, values, traditions, symbols, or food preferences.

3. The healthcare professional is preparing to use a stethoscope for auscultation. Which statement is true regarding the diaphragm of the stethoscope?

• A. Used to listen for high-pitched sounds
• B. Used to listen for low-pitched sounds
• C. Should be firmly held against the person's skin to block out low-pitched sounds
• D. Should be lightly held against the person's skin to listen for extra heart sounds and murmurs

Correct answer: A

Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.

4. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?

• A. The pulse is easier to palpate due to the rigidity of the blood vessels.
• B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
• C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
• D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.

Correct answer: B

Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.

5. Which of the following is a fat-soluble vitamin?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin B-6
• D. Riboflavin

Correct answer: B

Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
