Nursing Elites

1. 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.

2. During an examination, a nurse notices a draining ulceration on a patient's lower leg. What is the most appropriate action in this situation?

• A. Wash hands and then contact the physician.
• B. Continue to examine the ulceration and then wash hands.
• C. Wash hands, put on gloves, and continue with the examination of the ulceration.
• D. Wash hands, proceed with the rest of the physical examination, and perform the examination of the leg ulceration last.

Correct answer: C

Rationale: In this scenario, the most appropriate action is to wash hands, put on gloves, and then continue examining the ulceration. Wearing gloves is crucial when there is a possibility of contact with body fluids, as in the case of a draining ulceration. Contacting the physician is not necessary at this point; the immediate focus should be on proper infection control by washing hands and wearing gloves. Changing the order of the examination is not recommended as it is important to follow a systematic approach to avoid missing any crucial assessments.

3. When are manual hematocrits done?

• A. to monitor anemia
• B. by using a microhematocrit tube.
• C. to measure the percentage of plasma to cells.
• D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

4. A 60-year-old patient has been treated for pneumonia for the past 6 weeks. The patient is seen today in the clinic for an unexplained weight loss of 10 pounds over the last 6 weeks. Which is an appropriate rationale for this patient's weight loss?

• A. Chronic diseases such as hypertension do not usually cause weight loss.
• B. Weight loss is more likely due to underlying medical conditions than unhealthy eating habits.
• C. Unexplained weight loss often accompanies short-term illnesses.
• D. Weight loss is not typically caused by mental health dysfunctions.

Correct answer: C

Rationale: Unexplained weight loss in a patient with pneumonia could indicate an underlying short-term illness or a chronic condition like endocrine disease, malignancy, depression, anorexia nervosa, or bulimia. Hypertension is not commonly associated with weight loss; it usually leads to weight gain due to fluid retention. Unhealthy eating habits are less likely to explain significant unexplained weight loss over a short period. Mental health dysfunctions can affect appetite but are not typically primary causes of significant unexplained weight loss.

5. The nurse is assessing the vital signs of a 3-year-old patient who appears to have an irregular respiratory pattern. How would the nurse assess this child's respirations?

• A. Respirations should be counted for 1 full minute.
• B. Child's pulse and respirations should be simultaneously checked for 30 seconds and then multiplied by 2.
• C. Child's respirations should be checked for a minimum of 5 minutes to identify any variations in his or her respiratory pattern.
• D. Patient's respirations should be counted for 15 seconds and then multiplied by 4.

Correct answer: A

Rationale: To accurately assess a child's respiratory pattern, the nurse should count respirations for a full minute. This duration provides a comprehensive view of the child's breathing pattern, ensuring abnormalities are not missed. Counting for only 30 seconds may not capture irregularities effectively. Checking respirations for 5 minutes is excessive and unnecessary for a routine assessment. Counting for 15 seconds and multiplying by 4 is not as precise as a full-minute count. Pulse and respirations should not be checked simultaneously; instead, the nurse should count respirations unobtrusively while appearing to take the child's pulse. Therefore, the correct approach is to count the child's respirations for 1 full minute to obtain an accurate assessment.
