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. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?

• A. You will place the stethoscope over the heart and listen for any irregular beats.
• B. You will place the stethoscope over the heart and count the beats per minute.
• C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
• D. You will place your fingertip over the patient's wrist and count the beats per minute.

Correct answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.

3. A client is being transferred from a bed to a wheelchair. Which action is essential to maintain client safety in this situation?

• A. Position the wheelchair at the foot of the bed
• B. Maintain a space of at least 12 inches between the wheelchair and the bed
• C. Place the footplates in the lowest position before transferring the client
• D. Lock both wheels on the wheelchair before moving the client

Correct answer: D

Rationale: When transferring a client from a bed to a wheelchair, it is crucial to prioritize client safety. Locking both wheels on the wheelchair before moving the client is essential as it adds stability and prevents the wheelchair from moving unexpectedly during the transfer process. Placing the wheelchair at the foot of the bed allows for easier transfer, but ensuring the wheels are locked is more critical for safety. Maintaining a 12-inch space between the wheelchair and the bed is not as essential as ensuring wheel locks are engaged. While placing the footplates in the lowest position can enhance client comfort, it is not a safety measure that is as critical as securing the wheelchair by locking its wheels before the transfer.

4. What is the anatomic structure located in the middle of the heart that separates the right and left ventricles?

• A. Septum
• B. Sputum
• C. Separator
• D. None of the above

Correct answer: A

Rationale: The correct answer is the septum. The septum is a structure located in the middle of the heart that separates the right and left ventricles. It plays a crucial role in maintaining the separation between the two ventricles to ensure efficient blood flow. The other choices, 'Sputum' and 'Separator,' are incorrect as they do not refer to the anatomic structure in the heart that serves this specific function. 'Sputum' is a term used to describe phlegm or mucus, not an anatomical structure, and 'Separator' is a generic term that does not specifically identify the cardiac structure mentioned in the question.

5. An examiner is using an ophthalmoscope to examine a patient's eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?

• A. Rotating the lens selector dial to bring the object into focus
• B. Using the large full circle of light when assessing pupils that are not dilated
• C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
• D. Using the grid on the lens aperture dial to visualize the external structures of the eye

Correct answer: A

Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.
