Falls Introduction to Nursing Quizlet Questions
Question 1 of 5
After circulation has ceased, discoloration appears in the lowermost or dependent areas of the body of the deceased. This is known as:
Correct Answer: C
Rationale: The correct answer is C: Livor mortis. Livor mortis is the pooling of blood in the lowermost areas of the body post-mortem due to gravity. This occurs after circulation stops, causing discoloration in dependent areas. Algor mortis (choice A) refers to the cooling of the body after death, Rigor mortis (choice B) is the stiffening of muscles post-mortem, and Manor mortis (choice D) is not a recognized term in forensic science.
Question 2 of 5
In changing tracheostomy ties, the nurse should:
Correct Answer: C
Rationale: Rationale: Choice C is correct because it involves removing one side of the old tie before threading the clean tape through the eye of the flange. This method ensures that the tracheostomy remains secure while changing ties, reducing the risk of accidental decannulation or displacement. Removing both ties (Choice D) can compromise the patient's airway, while tying the new tie to the eye of the flange with old ties in place (Choice B) can lead to inadequate support. Choice A is incorrect because threading the clean tape through the eye of the flange before removing the old ties can result in instability and potential harm to the patient.
Question 3 of 5
The physician has ordered an indwelling catheter inserted in a hospitalized male patient. The nurse is aware that:
Correct Answer: A
Rationale: The correct answer is A because the male urethra is indeed vulnerable to injury during catheter insertion due to its narrow and curved structure. Step 1: Understanding male anatomy - the male urethra is longer and more prone to injury compared to the female urethra. Step 2: Recognizing the importance of gentle and careful insertion to prevent damage. Step 3: Emphasizing the need for proper technique and training to minimize the risk of harm. Summary: Choice B is vague and not relevant to catheter insertion. Choice C is incorrect as a sterile technique is typically used for catheter insertion. Choice D is incorrect as the catheter should be inserted 6-7 inches into the male urethra, not 2-3 inches.
Question 4 of 5
A client who is scheduled for a bone marrow aspiration asks the nurse about the site that will be used for the procedure. The nurse tells the client that in addition to the iliac crest, the____ may be used.
Correct Answer: C
Rationale: The correct answer is C: Sternum. The sternum is another common site for bone marrow aspiration, along with the iliac crest. The sternum is easily accessible, especially in emergency situations. Aspiration from the sternum is less painful compared to the iliac crest. The femur (choice A) is not typically used for bone marrow aspiration due to the risk of injury to major blood vessels. The ribs (choice B) are not ideal due to the risk of pneumothorax. The scapula (choice D) is not commonly used due to limited accessibility and risk of injury to surrounding structures.
Question 5 of 5
For a person to be immunocompetent, which processes need to be functional and interact appropriately with each other? (Select the one that does not apply.)
Correct Answer: D
Rationale: The correct answer is D: Red blood cells. Immunocompetence refers to the ability of the immune system to effectively respond to pathogens. Red blood cells are not directly involved in immune responses. Antibody-mediated immunity involves the production of antibodies by B cells to target pathogens. Cell-mediated immunity involves the activation of T cells to directly attack infected cells. Inflammation is a non-specific immune response that helps to eliminate pathogens. Red blood cells primarily function in oxygen transport and do not play a direct role in immune responses. Therefore, the correct answer is D as red blood cells do not need to be functional for a person to be immunocompetent.
