A nurse is caring for a patient who has acute kidney injury.
The patient’s ABGs are: pH: 7.26, PaCO2: 30 mm Hg, HCO3: 14 mEq/L. Which of the following acid-base imbalances should the nurse identify the patient is experiencing?

Metabolic alkalosis.

Metabolic acidosis.

Respiratory alkalosis.

Respiratory acidosis.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Metabolic alkalosis is characterized by a high pH (above 7.45), high bicarbonate (HCO3-) levels, and normal or low PaCO2. The patient's ABGs show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg), which are not consistent with metabolic alkalosis.

Choice C rationale:

Respiratory alkalosis is characterized by a high pH (above 7.45), low PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low PaCO2, but the pH is low (acidic) and the bicarbonate is low, which are not consistent with respiratory alkalosis.

Choice D rationale:

Respiratory acidosis is characterized by a low pH (below 7.35), high PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low pH, but the PaCO2 is also low, which is not consistent with respiratory acidosis.

Rationale for the correct answer, B:

Metabolic acidosis is characterized by a low pH (below 7.35), low bicarbonate levels, and normal or low PaCO2. The patient's ABGs are consistent with metabolic acidosis because they show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg).

Acute kidney injury is a common cause of metabolic acidosis. The kidneys play a vital role in regulating acid-base balance by excreting acids and reabsorbing bicarbonate. When the kidneys are damaged, they are unable to excrete acids effectively, leading to an accumulation of acids in the blood and a decrease in bicarbonate levels.

Additional Information:

It's important to note that the patient's low PaCO2 is likely a compensatory mechanism for the metabolic acidosis. In response to acidosis, the respiratory system tries to increase ventilation to blow off more carbon dioxide, which helps to raise the pH. However, this compensatory mechanism is often not enough to fully correct the acidosis.

Correct Answer is C

Explanation

Choice A rationale:

This response is dismissive of the patient's pain and does not offer any assistance. It also does not acknowledge the patient's concerns about their pain being a normal part of aging.

It's important to validate the patient's experience and offer support, even if the pain level is not severe.

This response could lead to the patient feeling unheard and unsupported, and it could potentially delay necessary treatment.

Choice B rationale:

This response suggests that the patient's pain is not significant enough to warrant treatment unless it worsens. This is not appropriate, as pain is subjective and should be treated based on the patient's individual experience.

Additionally, this response reinforces the patient's belief that pain is a normal part of aging, which may prevent them from seeking treatment in the future.

Choice C rationale:

This response is the best option because it acknowledges the patient's pain, expresses concern, and suggests further investigation.

It is important to rule out any underlying medical conditions that may be causing the pain.

This response also demonstrates to the patient that the nurse is taking their pain seriously and is committed to helping them manage it.

Choice D rationale:

This response acknowledges that pain can be a part of aging, but it also suggests that there may be a specific cause for the patient's pain.

This could lead to the patient feeling anxious or worried about their health.

It is important to investigate the cause of the pain before making any assumptions.

Correct Answer is ["50"]

Explanation

Here are the steps to calculate the gtt/min for the manual IV infusion:

Step 1: Convert the infusion time from hours to minutes. 8 hours x 60 minutes/hour = 480 minutes

Step 2: Divide the total volume of fluid (in mL) by the infusion time in minutes to get the mL/min rate. 400 mL ÷ 480 minutes = 0.8333 mL/min

Step 3: Multiply the mL/min rate by the drop factor (gtt/mL) to get the gtt/min rate. 0.8333 mL/min x 60 gtt/mL = 50 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min.
