1. 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: PT/INR

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.

2. A client has fallen asleep in his bed in the hospital. His heart rate is 65 bpm, his muscles are relaxed, and he is difficult to arouse. Which stage of the sleep cycle is this client experiencing?

• A. Stage 1
• B. Stage 2
• C. Stage 3
• D. Stage 4

Correct answer: Stage 3

Rationale: The client in this scenario is experiencing stage 3 of the sleep cycle. In stage 3, the individual has moved into deeper stages of sleep, making it difficult to arouse. Characteristics of stage 3 include relaxed muscles, a decrease in vital signs, and being very still. Stage 3 is a phase of non-REM sleep where the client progresses towards REM sleep and vivid dreams. Choices A, B, and D are incorrect. Stage 1 is characterized by light sleep, stage 2 is a slightly deeper sleep with sleep spindles and K-complexes, and stage 4 is the deepest stage of sleep with the slowest brain waves.

3. A patient's urine tests positive for glucose. The doctor asks you to confirm this finding. Which of the following would BEST confirm this finding?

• A. Run the urine on the hand-held glucometer.
• B. Have another MA perform a repeat dipstick test.
• C. Run a Clinitest.
• D. Run an Acetest.

Correct answer: Run a Clinitest.

Rationale: To confirm glucosuria, the most appropriate method is to run a Clinitest. Clinitest tablets are specifically designed to detect glucose in urine samples. This test is particularly useful when the urine is discolored, making it challenging to accurately assess the color change.\n Choice A, using a hand-held glucometer, is not the standard method for confirming glucose in urine; these devices are primarily used for blood glucose monitoring.\n Choice B, having another Medical Assistant perform a repeat dipstick test, may not provide a more definitive confirmation as dipstick tests can sometimes yield false positives or be less accurate compared to other methods like the Clinitest.\n Choice D, running an Acetest, is used to detect ketones in the urine, not glucose. Ketones are typically associated with conditions like diabetic ketoacidosis, which is different from glucosuria.

4. 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: Palpate for 1 minute if the rhythm is irregular.

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.

5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: Yield a falsely high blood pressure

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
