Question 1 of 5
The nurse is to perform a routine blood glucose check on a diabetic client before administering insulin. Which action is correct?
Correct Answer: B
Rationale: Puncturing the finger's side avoids nerve-rich areas, ensuring accurate and less painful glucose testing.
Question 2 of 5
Which of these clients would the nurse monitor for the complication of C. difficile diarrhea?
Correct Answer: D
Rationale: A middle-aged client receiving radiation for throat cancer. Radiation therapy, particularly to the abdomen or pelvis, can disrupt the gut microbiota and increase the risk of C. difficile infection, especially if the client is also receiving antibiotics or has a weakened immune system.
Question 3 of 5
A client who had a total thyroidectomy this morning returns to the nursing care unit. How should the nurse position the client?
Correct Answer: A
Rationale: Semi-sitting reduces neck swelling and promotes airway patency post-thyroidectomy. Supine, prone, or Sims' positions increase complications.
Question 4 of 5
A client is being treated for cancer with linear acceleration radiation. The physician has marked the radiation site with a blue marking pen. The nurse should:
