A nurse evaluates the following arterial blood gas values in a patient: pH 7.48, PaO 98 mm Hg, PaCO 28 mm Hg, and HCO - 22 mEq/L (22 mmol/L). Which patient condition does the nurse correlate with these results?

Diarrhea and vomiting for 36 hours

Chronic obstructive pulmonary disease (COPD)

Anxiety-induced hyperventilation

Diabetic ketoacidosis and chronic obstructive pulmonary disease (COPD)

Answer and Explanation

The Correct Answer is C

A. Diarrhea and vomiting for 36 hours:

Diarrhea and vomiting can lead to metabolic acidosis due to loss of bicarbonate and increased hydrogen ion concentration in the blood. However, the ABG values provided indicate respiratory alkalosis (high pH and low PaCO2), which is not consistent with metabolic acidosis caused by diarrhea and vomiting. Therefore, this choice does not correlate with the ABG values.

B. Chronic obstructive pulmonary disease (COPD):

COPD is a respiratory condition characterized by airflow limitation and increased airway resistance. It can lead to respiratory acidosis due to retention of carbon dioxide (PaCO2 levels would be elevated). The ABG values in the scenario show respiratory alkalosis (low PaCO2), which is the opposite of what would be expected in COPD. Therefore, this choice does not correlate with the ABG values provided.

C. Anxiety-induced hyperventilation:

Anxiety-induced hyperventilation is a common cause of respiratory alkalosis. During hyperventilation, there is excessive elimination of carbon dioxide (PaCO2 levels decrease), leading to an increase in pH (alkalosis). The ABG values in the scenario show a high pH (7.48) and low PaCO2 (28 mm Hg), consistent with respiratory alkalosis seen in hyperventilation due to anxiety.

D. Diabetic ketoacidosis and chronic obstructive pulmonary disease (COPD):

Diabetic ketoacidosis (DKA) is a metabolic condition characterized by hyperglycemia, ketosis, and metabolic acidosis (low pH and low bicarbonate levels). COPD, as mentioned earlier, can lead to respiratory acidosis due to retained carbon dioxide. Neither of these conditions correlates with the ABG values provided, which show respiratory alkalosis (high pH and low PaCO2). Therefore, this choice does not correlate with the ABG values.

Correct Answer is A

Explanation

A. High-protein diet with vitamins and mineral supplements:

This choice indicates a good understanding of preventing pressure ulcers. High-protein diets are beneficial for tissue repair and wound healing. Adequate protein intake supports collagen synthesis, which is essential for maintaining skin integrity and healing wounds. Additionally, vitamins and mineral supplements can contribute to overall nutritional status and support tissue health.

B. Low-fat diet with whole grains and cereals and vitamin supplements:

While a low-fat diet and whole grains are generally healthy choices, they may not specifically address the needs of a patient at risk for pressure ulcers. Fat is important for skin health, and whole grains can contribute to overall nutrition, but protein and specific vitamins and minerals are more directly related to tissue repair and wound healing.

C. Vegetarian diet with nutritional supplements and fish oil capsules:

A vegetarian diet can be healthy, but it requires careful planning to ensure adequate protein intake, especially for tissue repair and wound healing. Nutritional supplements may help fill nutrient gaps, but specific attention to protein sources is crucial for preventing pressure ulcers. Fish oil capsules can provide omega-3 fatty acids, which may have some benefits for skin health.

D. Low cholesterol, high-fiber, low-carbohydrate diet:

This diet choice focuses more on cardiovascular health and weight management rather than addressing the needs of a patient at risk for pressure ulcers. While a balanced diet with adequate fiber can support overall health, protein intake and specific vitamins and minerals are more critical for skin integrity and wound healing.

A. Measure the depth and width of the wound. B. Educate the client about the need for antibiotics. C. Consult a nutritionist for a diet plan. D. Remove any non-viable tissue.

Correct Answer is ["A","B","C","D"]

Explanation

A. Measure the depth and width of the wound. Regular assessment and documentation of the wound’s size can help track the progress of healing and effectiveness of the treatment plan.

B. Educate the client about the need for antibiotics. If an infection is present, antibiotics may be necessary. It’s important for the client to understand the purpose and proper use of these medications.

C. Consult a nutritionist for a diet plan. Good nutrition is essential for wound healing. Certain nutrients, like protein, vitamin C, and zinc, can promote wound healing.

D. Remove any non-viable tissue. Debridement, or the removal of dead (non-viable) tissue, can help promote the healing of the wound by reducing the risk of infection and allowing healthy tissue to grow.
