1. The abbreviation ac is defined as _____________.

A. before the meal
B. with the meal
C. after the meal
D. ante cibum

Correct answer: A

Rationale: The correct answer is 'before the meal.' The abbreviation 'ac' is derived from the Latin term 'ante cibum,' which translates to 'before a meal.' Choices B, C, and D are incorrect because 'ac' does not refer to 'with the meal,' 'after the meal,' or 'ante corpis.' It specifically denotes something occurring before a meal, making option A the correct choice in this context.

2. 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.

3. Where is the duodenum located in the digestive system?

A. It is the first part of the small intestine, located immediately after the stomach.
B. It is the section of the digestive system where the gall bladder delivers bile.
C. It is the section of the small intestine where the pancreas delivers digestive juices.
D. None of the above.

Correct answer: D

Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.

4. A nurse is preparing to change a client's dressing for a burn wound on his foot. Which of the following interventions is appropriate for this process?

A. Wash the wound with cleanser, rinse, and pat dry
B. Bind the wound tightly, secure with tape, and elevate the foot
C. Contact the physician after the dressing change is complete
D. Provide analgesics for the client after the procedure

Correct answer: A

Rationale: When changing the dressing for a burn wound, it is essential to follow appropriate interventions to prevent infection, reduce pain, and support healing. In this scenario, after removing the old dressing, it is crucial to wash the wound gently with a suitable cleanser, rinse the area thoroughly, and then pat it dry. This process helps in maintaining cleanliness, reducing the risk of infection, and providing a conducive environment for healing. Binding the wound tightly (Choice B) can impede circulation and delay healing. Contacting the physician after the dressing change (Choice C) may be necessary in specific situations but is not a standard step in routine dressing changes. Providing analgesics after the procedure (Choice D) is important for pain management but is not directly related to the dressing change itself.

5. An experienced healthcare professional instructs a new colleague on caring for a patient with dyspnea due to a pulmonary fungal infection. Which action by the new colleague indicates a need for further teaching?

A. Listening to the patient's lung sounds several times during the shift
B. Placing the patient in droplet precautions and in a private hospital room
C. Increasing the oxygen flow rate to maintain oxygen saturation above 90%
D. Monitoring the patient's serology results to identify the specific infecting organism

Correct answer: B

Rationale: The correct answer is placing the patient in droplet precautions and in a private hospital room. Fungal infections are not transmitted from person to person, so isolation procedures like droplet precautions are unnecessary. Listening to the patient's lung sounds, increasing the oxygen flow rate, and monitoring serology results are all appropriate actions in caring for a patient with dyspnea caused by a pulmonary fungal infection.
