1. 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.
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. Your patient who had AIDS/HIV has just died. Should you still use standard precautions as you provide post-mortem care?
- A. Yes, because the virus is still transmissible
- B. Yes, because respect must still be maintained
- C. No, because the virus is no longer transmissible
- D. No, because it is disrespectful
Correct answer: A
Rationale: Yes, you should still use standard precautions even after an HIV/AIDS patient has died. The virus can remain infectious after death, and healthcare workers need to protect themselves from potential exposure. Choice B is incorrect because while respect is important, the primary reason for using standard precautions is to prevent transmission of infectious diseases. Choice C is incorrect as the virus can still be transmissible even after the patient's death. Choice D is incorrect as using standard precautions is a matter of infection control, not a question of respect.
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 is the most effective action for controlling the spread of infection?
- A. Thorough hand hygiene
- B. Wearing gloves and masks when providing direct client care
- C. Implementing appropriate isolation precautions
- D. Administering broad-spectrum prophylactic antibiotics
Correct answer: A
Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.
