Nursing Elites

1. A nurse is assessing the status of a client with diabetes mellitus. The nurse concludes that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1C (HbA1C) is less than:

• A. 7%
• B. 9%
• C. 10%
• D. 15%

Correct answer: A

Rationale: The correct answer is A: 7%. Glycosylated hemoglobin A1C (HbA1C) level of 7.0% or less is considered indicative of adequate diabetic control. This level reflects good long-term blood sugar management. Choices B, C, and D are incorrect because an HbA1C level above 7% indicates poor diabetic control and an increased risk of complications associated with diabetes, such as cardiovascular disease, neuropathy, and retinopathy.

2. The client is receiving teletherapy radiation for a malignant tumor. Which instruction regarding skin care of the portal site should the nurse provide?

• A. Protect the skin of the radiation portal site from sunlight exposure
• B. Apply moisturizing lotions daily to the radiation portal site
• C. Avoid washing the skin inside the radiation portal site
• D. Remove the ink marks of the portal after each radiation treatment

Correct answer: A

Rationale: Protecting the skin from sunlight exposure is crucial to prevent radiation burns and additional skin damage at the treatment site. Sun exposure can exacerbate skin reactions caused by radiation therapy. Applying moisturizing lotions daily may introduce foreign substances or irritants to the treated area, leading to potential complications. Washing the skin inside the radiation portal site is important for maintaining cleanliness and preventing infections. Removing the ink marks after each treatment is unnecessary and may cause unnecessary skin irritation and trauma.

3. A nursing student is suctioning a client through a tracheostomy tube while a nurse observes. Which action by the student would prompt the nurse to intervene and demonstrate the correct procedure? Select all that apply.

• A. Setting the suction pressure to 60 mm Hg
• B. Applying suction throughout the procedure
• C. Assessing breath sounds before suctioning
• D. Placing the client in a supine position before the procedure

Correct answer: A

Rationale: The correct suction pressure for an adult client with a tracheostomy tube is typically between 80 to 120 mm Hg. Suction should be applied intermittently during catheter withdrawal to avoid damaging the airway. Assessing breath sounds before suctioning is important to ensure the procedure is necessary. Placing the client in a supine position before suctioning can compromise their airway; instead, the head of the bed should be elevated to facilitate proper drainage and reduce the risk of aspiration. Therefore, setting the suction pressure to 60 mm Hg is incorrect and would prompt the nurse to intervene and correct the procedure.

4. What is the correct procedure for performing an ophthalmoscopic examination on a client's right retina?

• A. Instruct the client to focus on a distant object behind the examiner and not move their eyes during the exam.
• B. Set the ophthalmoscope on the plus 2 to 3 lens and hold it in front of the examiner's right eye.
• C. From a distance of 12 to 15 inches and slightly to the side, shine the light into the client's pupil.
• D. For optimal visualization, keep the ophthalmoscope at least 3 inches from the client's eye.

Correct answer: C

Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.

5. A client was admitted for a myocardial infarction and cardiogenic shock 2 days ago. Which laboratory test result should a nurse expect to find?

• A. Blood urea nitrogen (BUN) of 52 mg/dL
• B. Creatinine of 2.3 mg/dL
• C. BUN of 10 mg/dL
• D. BUN/creatinine ratio of 8:1

Correct answer: A

Rationale: In cardiogenic shock, decreased renal perfusion leads to an elevated BUN. Choice A is correct. Creatinine remains normal in cardiogenic shock as it signifies kidney damage, which has not occurred in this case. A low BUN indicates overhydration, malnutrition, or liver damage, which are not typically seen in cardiogenic shock. A low BUN/creatinine ratio is associated with fluid volume excess or acute renal tubular acidosis, not specifically indicative of cardiogenic shock.
