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.

A healthcare professional is employed at a district health department and must spend several hours each day sitting at a desk. Which principle of ergonomics will most likely help them to reduce the risk of injury or pain in this situation?
- A. Adjust the chair height to keep the legs bent at the hips at a 90-degree angle
- B. Maintain the position of the computer monitor just below eye level
- C. Stand up and take a walk or stretch every 4 hours
- D. Rest wrists on the edge of the desk while typing
Correct Answer: A
Rationale: When sitting for prolonged periods, it is important to adjust the height of the chair so that the legs are bent at the hips at a 90-degree angle. This position helps to reduce pressure on the back, legs, and feet, promoting better posture and reducing muscle fatigue. Standing up and moving around at least once every hour is crucial to support circulation and prevent stiffness. Maintaining the position of the computer monitor just below eye level helps reduce strain on the neck and eyes. Resting wrists on the edge of the desk while typing can lead to wrist strain and discomfort, so it is not an ergonomic recommendation for prolonged desk work.
A client is suspected of having carbon monoxide poisoning. Which of the following symptoms are associated with this condition?
- A. Red rash across the trunk and extremities
- B. Nausea, vomiting, seizures
- C. Flushing of the face and neck
- D. Abdominal pain radiating to the back
Correct Answer: B
Rationale: The correct answer is 'Nausea, vomiting, seizures.' Carbon monoxide poisoning can present with symptoms such as headache, dizziness, weakness, nausea, vomiting, and confusion. Severe cases can progress to seizures, coma, and even death. It is crucial for healthcare providers to recognize these symptoms promptly to initiate appropriate treatment. Choices A, C, and D are incorrect because a red rash, flushing of the face and neck, and abdominal pain radiating to the back are not typically associated with carbon monoxide poisoning. It is essential to be aware of the common manifestations of carbon monoxide poisoning to ensure timely intervention and prevent adverse outcomes.
Which of the following is the correct sequence for removing personal protective equipment?
- A. Remove gown, gloves, shoe covers, mask
- B. Remove mask, gloves, gown, shoe covers
- C. Remove gloves, gown, mask, shoe covers
- D. Remove shoe covers, mask, gloves, gown
Correct Answer: C
Rationale: The correct sequence for removing personal protective equipment is crucial to prevent contamination. When exiting a surgical or aseptic situation, the proper sequence is to first remove gloves, followed by the gown, mask, and finally shoe covers. This order ensures that potentially contaminated items are removed first, minimizing the risk of exposure. Choice A, 'Remove gown, gloves, shoe covers, mask,' is incorrect as gloves should be removed before the gown. Choice B, 'Remove mask, gloves, gown, shoe covers,' is incorrect as gloves should be removed first. Choice D, 'Remove shoe covers, mask, gloves, gown,' is incorrect as gloves should be the first item removed to prevent contamination.
You are taking care of a patient who has active TB. The patient has been put on airborne precautions and is in a special room. You must wear a HEPA mask when you enter the room. Now, the patient has to leave the room and go to the radiology department. How can you transport this patient to the radiology department without spreading TB throughout the hospital?
- A. Have everyone along the route to the radiology department wear a HEPA mask.
- B. Have patients along the route to the radiology department wear a HEPA mask.
- C. Have staff along the route to the radiology department wear a HEPA mask.
- D. Place a HEPA mask on the patient.
Correct Answer: D
Rationale: To prevent the spread of TB throughout the hospital, it is essential to place a HEPA mask on the patient before transporting them to the radiology department. Expecting everyone along the route to wear a HEPA mask is not practical due to the high cost and the need for special fittings. Having patients or staff wear HEPA masks along the route is also not feasible and may not effectively contain the spread of TB.
Mr. and Mrs. K have just adopted a newborn infant and are preparing to take him home from the hospital for the first time. Which safety measure is most appropriate for the clients in this situation?
- A. Turn the handles of pans on the stove inward
- B. Set up a baby gate at the top of the stairs
- C. Cover electrical outlets with child-proof plugs
- D. Install an approved car seat that is facing backward in the back seat
Correct Answer: D
Rationale: Parents of newborn infants should use an approved car seat that has been installed facing backward in the back seat of the car. Securing infants in car seats, even from the first ride home from the hospital, promotes safety while transporting. While safety measures at home such as baby gates or outlet covers are important, they are not the priority safety measures until the baby is old enough to be mobile. The car seat is crucial for protecting the newborn during transportation, ensuring proper positioning and restraint in the event of sudden stops or accidents. Turning handles of pans on the stove inward, setting up a baby gate, and covering electrical outlets are important safety measures at home but are not as critical for the immediate safety of a newborn during transportation.
