1. Each small square on the EKG paper is:

• A. 0.04 seconds long and 5mm tall
• B. 0.2 seconds long and 5mm tall
• C. 0.04 seconds long and 20mm tall
• D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

2. A client is taking a walk down the hallway when she suddenly realizes that she needs to use the restroom. Although she tries to make it to the bathroom on time, she is incontinent of urine before reaching the toilet. What type of incontinence does this situation represent?

• A. Relex incontinence
• B. Urge incontinence
• C. Total incontinence
• D. Functional incontinence

Correct answer: D

Rationale: Functional incontinence occurs when a client develops an urge to void but may not be able to reach the toilet in time. In this scenario, the client had the urge to use the restroom but was unable to make it in time, leading to incontinence. Functional incontinence may be related to conditions that cause the client to forget bladder sensation until the last minute, such as cognitive changes, or the client may have mobility problems that prevent her from reaching the bathroom in time. Choice A, Reflex incontinence, is incorrect as reflex incontinence is characterized by the involuntary loss of urine due to hyperreflexia of the detrusor muscle. Choice B, Urge incontinence, is not the correct answer as urge incontinence is the involuntary loss of urine associated with a strong desire to void. Choice C, Total incontinence, is also incorrect as it refers to the continuous and unpredictable loss of urine, not specifically related to the inability to reach the toilet in time.

3. 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.

4. Specific gravity in urinalysis:

• A. compares the concentration of urine to that of distilled water
• B. is useless when the patient is dehydrated
• C. can only be measured using a refractometer
• D. None of the above

Correct answer: A

Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.

5. Intermittent fevers are:

• A. fevers which come and go.
• B. fevers which rise and fall but are always considered above the patient's average temperature.
• C. fevers which fluctuate more than three degrees and never return to normal.
• D. None of the above.

Correct answer: A

Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature. Choice A is correct as it accurately describes intermittent fevers. Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature. Choice D is incorrect as there is a specific definition for intermittent fevers.
