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. A client is complaining of pain in his right hand after surgery. The IV in his hand has slowed down, and the skin around the site is reddened and cool. The client reports localized pain in the hand and fingers. What is the most likely cause of this client's pain?

• A. The client's IV is infiltrated
• B. The client is experiencing phlebitis from the last drug administered
• C. The client has a blood clot developing in the distal arteries of the wrist
• D. The client's pain is associated with myocardial ischemia and he is having a heart attack

Correct answer: A

Rationale: Pain, cool skin, and edema at an IV injection site indicate IV infiltration. The reddened and cool skin around the IV site, along with localized pain and a slowed IV drip rate, are classic signs of infiltration. Infiltration occurs when IV fluids or medications enter the surrounding tissues instead of the vein, leading to potential tissue damage. Phlebitis is inflammation of a vein, not infiltration. A blood clot in the distal arteries of the wrist would not cause these specific symptoms. Myocardial ischemia and heart attack are unrelated to the client's localized hand pain and IV issues.

3. Which of the following signs or symptoms indicates a possible nutritional deficiency?

• A. Subcutaneous fat at the waist and abdomen
• B. Presence of papillae on the surface of the tongue
• C. Straight arms and legs
• D. Pale conjunctiva

Correct answer: D

Rationale: A client with poor nutritional intake may have pale mucous membranes surrounding the eye, or the conjunctiva. This area should normally be pink, indicating good circulation and a lack of irritation or dryness. Improper nutrition can manifest as numerous signs in the body, including bowed legs, pale mucous membranes, a smooth or beefy tongue, and poor muscle tone. Subcutaneous fat at the waist and abdomen is not a sign of nutritional deficiency but rather of excess fat deposition. The presence of papillae on the surface of the tongue is normal and not indicative of a nutritional deficiency. Straight arms and legs are also typical anatomical features and not specifically related to nutritional deficiencies.

4. When educating a client about their new prescription for warfarin, what should the nurse advise?

• A. To have his white blood cell count tested once a month
• B. To avoid any activities that could lead to injury
• C. To avoid eating leafy green vegetables
• D. Both A and B

Correct answer: B

Rationale: The correct answer is to advise the client to avoid any activities that could lead to injury when taking warfarin. Warfarin is an anticoagulant medication that decreases blood clotting, increasing the risk of bleeding. Engaging in activities that may result in injury can lead to uncontrolled bleeding, which can be serious. While monitoring white blood cell count is not specifically related to warfarin therapy, avoiding leafy green vegetables is important due to their vitamin K content, which can interfere with warfarin's effectiveness. Therefore, the client should be educated to avoid activities that could cause injury to prevent potential bleeding complications.

5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
