Nursing Elites

1. 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.

2. Surgical asepsis is being performed when:

• A. wiping down exam tables with bleach
• B. sterilizing instruments
• C. changing table paper
• D. wearing gloves when performing injections

Correct answer: B

Rationale: Surgical asepsis refers to the process of maintaining a sterile environment to prevent the introduction of pathogens to a patient's body. Sterilizing instruments is a crucial aspect of surgical asepsis as it ensures that the instruments used during procedures are free from microorganisms that could cause infections. Wiping down exam tables with bleach may help in cleaning and disinfecting surfaces but does not pertain directly to maintaining a sterile field. Changing table paper is important for cleanliness and infection control but is not specifically related to surgical asepsis. Wearing gloves when performing injections is important for standard precautions and preventing the spread of infection but does not encompass the concept of surgical asepsis, which focuses on maintaining a sterile field during invasive procedures.

3. What does the term 'Afferent Nerve' mean?

• A. Carrying an impulse to the brain
• B. Carrying an impulse away from the brain
• C. Carrying impulses to the motor neurons of the appendicular muscles
• D. None of the above

Correct answer: A

Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'

4. In which situation would the nurse use bimanual palpation technique?

• A. Palpating the thorax of an infant
• B. Palpating the kidneys and uterus
• C. Assessing pulsations and vibrations
• D. Assessing the presence of tenderness and pain

Correct answer: B

Rationale: Bimanual palpation involves using both hands to envelop or capture specific body parts or organs like the kidneys, uterus, or adnexa. This technique is particularly useful for assessing the size, shape, consistency, and mobility of deep organs like the kidneys and uterus. Palpating the thorax of an infant (Choice A) is usually done with a different technique like gentle, single-handed palpation. Assessing pulsations and vibrations (Choice C) and assessing tenderness and pain (Choice D) typically do not require the use of bimanual palpation, making Choices A, C, and D incorrect.

5. The healthcare provider is preparing to perform a physical assessment. Which statement is true about the inspection phase of the physical assessment?

• A. Usually yields little information
• B. Takes time and reveals a surprising amount of information
• C. May be somewhat uncomfortable for the expert practitioner
• D. Requires a thorough examination of the patient's body before proceeding with palpation

Correct answer: B

Rationale: During the inspection phase of a physical assessment, it is essential to take time as it can reveal a significant amount of information. Initially, it may feel uncomfortable for the examiner to focus solely on observing the patient without immediate action. Rushing through inspection is not recommended as it can lead to missing important cues. Train yourself to be thorough during inspection by observing carefully and taking the time needed to gather essential data. Choices A, C, and D are incorrect because inspection typically provides valuable information, may feel uncomfortable at first but is necessary for a comprehensive assessment, and does not involve a quick glance but requires a focused and detailed observation.
