1. 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.

2. Over a patient's lifespan, how does the pulse rate change?

• A. starts out fast and decreases as the patient ages.
• B. starts out slower and increases as the patient ages.
• C. varies from slow to fast throughout the lifespan.
• D. stays consistent from birth to death.

Correct answer: A

Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.

3. What is the most effective step in hand washing?

• A. Using friction to remove potential pathogens.
• B. Using hospital-grade soap.
• C. Moisturizing the hands after washing to prevent cracking.
• D. Washing hands with soap for at least 15 seconds.

Correct answer: A

Rationale: The most effective step in hand washing is using friction to remove potential pathogens. While using soap, moisturizing hands, and washing for a sufficient duration are important aspects of hand hygiene, the mechanical action of rubbing hands together with friction is crucial in dislodging and removing dirt, debris, and potential pathogens. Hospital-grade soap may be beneficial, but the physical act of friction is key to effective hand washing. Moisturizing after washing is important for skin health but not the most effective step in the hand washing process. Simply washing hands for a specific duration, such as 15 seconds, without proper friction may not effectively remove contaminants. Therefore, using friction for thorough cleaning is the most crucial step in hand washing.

4. When turning an immobile bedridden client without assistance, which action by the nurse best ensures client safety?

• A. Securely grasp the client's arm and leg.
• B. Put bed rails up on the side of bed opposite from the nurse.
• C. Correctly position and use a turn sheet.
• D. Lower the head of the client's bed slowly

Correct answer: B

Rationale: When turning an immobile bedridden client without assistance, the best action to ensure client safety is to put bed rails up on the side of the bed opposite from the nurse. This is important because the nurse can only stand on one side of the bed, so having bed rails on the opposite side prevents the client from falling out of bed. Option A, which suggests securely grasping the client's arm and leg, can potentially cause client injury to the skin or joints. Options C and D, correctly positioning and using a turn sheet, and lowering the head of the client's bed slowly, respectively, are useful techniques during client turning but are of lower priority in terms of safety compared to the use of bed rails.

5. Which practice will help reduce the risk of a needlestick injury?

• A. Expose the end of the needle only when ready to enter the room for the procedure
• B. Never recap a needle after use
• C. Keep a sharps container nearby where it can be easily accessed
• D. Exchange needles from a central area rather than passing them between workers

Correct answer: C

Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.
