1. Which of the following may represent an upper airway obstruction?

• A. Retractions
• B. Elongated expiratory phase
• C. Stridor
• D. Expiratory wheezing

Correct answer: C

Rationale: Stridor is the sound produced by turbulent airflow through a partially obstructed upper airway. It is a classic sign of upper airway obstruction. While an elongated expiratory phase may indicate lower airway obstruction, stridor specifically points to an upper airway issue. Retractions are also often seen in upper airway obstruction due to the increased effort of breathing. Expiratory wheezing, on the other hand, is more indicative of lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD).

2. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?

• A. PT/INR
• B. CBC
• C. PTT
• D. WBC

Correct answer: A

Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.

3. Which technique is correct when assessing the radial pulse of a patient?

• A. Palpate for 1 minute if the rhythm is irregular.
• B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
• C. Palpate for 2 full minutes to detect any variation in amplitude.
• D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.

4. A client is post-op day #1 after a hemilaminectomy. The nurse removes the dressing as ordered and notes that the incision appears slightly red, with a small amount of serous drainage coming from the site. The edges of the incision are approximated. What is the next action of the nurse?

• A. Assist the client to shower as ordered and monitor the site for further changes
• B. Instruct the client to lie prone to allow the site to dry
• C. Place antibiotic ointment and a sterile dressing over the site
• D. Notify the physician for an antibiotic order

Correct answer: A

Rationale: An incision that appears slightly red with a small amount of serous drainage on the first day following surgery is going through a normal healing process. It is important to keep the incision clean. In this case, the nurse should assist the client to shower as ordered to maintain hygiene and monitor for changes in the incision site. Instructing the client to lie prone may not be necessary and could cause discomfort. Applying antibiotic ointment without a specific order is not recommended as it can interfere with the healing process. Notifying the physician for an antibiotic order is premature at this stage since the incision is showing normal signs of healing.

5. 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.
