A nurse is reinforcing dietary teaching with the guardians of a toddler. Which of the following snack foods should the nurse recommend?

Answer: B. Reposition the probe every 2 hours.

Rationale:

• A. Warm the skin prior to probe placement:While cold fingers can lead to inaccurate readings,warming the skin is not an essential step and is not routinely recommended in clinical practice.
• B. Reposition the probe every 2 hours:This iscorrect.Continuous pressure from the probe in one spot can cause skin breakdown and pressure injuries.Repositioning the probe every 2 hours helps to prevent this and ensure accurate readings.
• C. Tape the wire to the palm of the hand:This is incorrect.The pulse oximeter probe should be placed on a vascular site,such as a fingertip or earlobe.Taping the wire to the palm would not provide accurate readings.
• D. Apply the sensor to the index fingernail:This is incorrect.The fingernail does not have sufficient blood flow for accurate pulse oximetry readings.The probe should be placed on the fleshy pad of the fingertip.

Therefore, the most important action for the nurse to take is to reposition the probe every 2 hours to prevent skin breakdown and ensure accurate readings.

Additional Points:

• The nurse should also choose a clean and dry site for probe placement.
• The probe should be snug but not too tight.
• The nurse should monitor the child for signs of skin breakdown,such as redness,swelling,or pain.
• If the child is restless or active,the nurse may need to secure the probe with additional tape or a special wrap.

Choice A rationale:
Hypertension is a common manifestation of acute glomerulonephritis. The inflammation of the glomeruli in the kidneys can lead to impaired filtration, causing fluid retention and an increase in blood pressure. Monitoring the child's blood pressure is crucial to assess the severity of the condition and guide appropriate interventions.
Choice B rationale:
Dehydration is not a typical manifestation of acute glomerulonephritis. In fact, this condition often leads to fluid retention due to impaired kidney function. The child might experience edema and hypertension rather than dehydration.
Choice C rationale:
Muehrcke lines on the nails are not associated with acute glomerulonephritis. Muehrcke lines are white lines that appear horizontally across the nails and are typically indicative of hypoalbuminemia, which is not a primary feature of glomerulonephritis.
Choice D rationale:
Hypokalemia, or low potassium levels, is not a characteristic manifestation of acute glomerulonephritis. This condition primarily affects the kidneys' ability to filter waste and excess fluid, leading to fluid retention, electrolyte imbalances, and hypertension.
