Nursing Elites

1. What procedure examines a portion of the large intestine with an endoscope?

• A. Colposcopy
• B. Sigmoidoscopy
• C. Upper GI
• D. Cardiac catheterization

Correct answer: B

Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.

2. A client is receiving high-dose brachytherapy as a form of cancer treatment. What type of teaching must the nurse include when educating this client about safety?

• A. The client must remain in isolation under airborne precautions
• B. The client should stay in a private room at the hospital
• C. The client may need to limit visits from friends and family
• D. Both B and C

Correct answer: D

Rationale: A client undergoing high-dose brachytherapy has a radiation implant placed for cancer treatment. To ensure safety, the client should be in a private hospital room to prevent radiation exposure to others. Limiting visits from friends and family is necessary to prevent overexposure. Option A is incorrect as isolation under airborne precautions is not required for brachytherapy. Option B and C are the correct choices as they focus on minimizing radiation exposure to others, ensuring safety during treatment.

3. 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.

4. When considering the structural organization of the human body, what is the basic unit of life?

• A. Chemicals
• B. Atoms
• C. Molecules
• D. Cells

Correct answer: D

Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.

5. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?

• A. Standard Precautions apply to all body fluids, except sweat.
• B. Alcohol-based hand rub should be used if hands are not visibly dirty.
• C. Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
• D. Standard Precautions are to be used only when non-intact skin, excretions containing visible blood, or expected contact with mucous membranes are present.

Correct answer: C

Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.
