A client has a nasogastric (NG) tube placed during abdominal surgery. During postoperative convalescence, the nurse identifies that the client is manifesting a hand tremor, muscle twitching, and confusion. Which arterial blood gases consistent with metabolic alkalosis should the nurse report to the healthcare provider?

Reference Range pH 17.35 to 7.45]

PaCO2 135 to 45 mm Hg]

HCO3 [21 to 28 mEq/L or 21 to 28 mmol/L]

PaO2 [80 to 100 mm Hg]

pH 7.30, PCO, 20 mm Hg, HCO, 22 mEq/L (22 mmol/L), PO, 85 mm Hg.

pH 7.46, PCO, 55 mm Hg, HCO, 36 mEq/L (36 mmol/L), PO, 95 mm Hg.

pH 7.49, PCO, 45 mm Hg, HCO, 32 mEq/L (32 mmol), PO, 90 mm Hg.

pH 7.29, PCO, 35 mm Hg, HCO, 25 mEq/L (25 mmol/L), PO, 99 mm Hg.

Answer and Explanation

The Correct Answer is B

B. pH 7.46, PCO2 55 mm Hg, HCO3 36 mEq/L, PO2 95 mm Hg

The pH is high (alkalotic).

The HCO3 level is elevated, indicating metabolic alkalosis.

The PCO2 is high (respiratory acidotic picture due to secondary response). This option matches the criteria for metabolic alkalosis.

A. pH 7.30, PCO2 20 mm Hg, HCO3 22 mEq/L, PO2 85 mm Hg

The pH is low (acidic), not alkalotic.

The HCO3 level is within the normal range.

The PCO2 is low, which could indicate respiratory alkalosis. This option does not match the criteria for metabolic alkalosis.

C. pH 7.49, PCO2 45 mm Hg, HCO3 32 mEq/L, PO2 90 mm Hg The pH is high (alkalotic).

The HCO3 level is elevated, indicating metabolic alkalosis. The PCO2 is within the normal range.

This option does not meet the criteria for metabolic alkalosis D pH 7.29, PCO2 35 mm Hg, HCO3 25 mEq/L, PO2 99 mm Hg

The pH is low (acidic), not alkalotic. The HCO3 level is low, not elevated. The PCO2 is within the normal range.

This option does not match the criteria for metabolic alkalosis.

Correct Answer is C

Explanation

C. Type I hypersensitivity reactions, also known as immediate hypersensitivity reactions, involve the production of IgE antibodies in response to an allergen. In this case, the bee sting likely triggered an IgE-mediated immune response, leading to the release of inflammatory mediators such as histamine. The client's symptoms of body rash, shortness of breath, tachycardia, and hypotension are characteristic of anaphylaxis, which is a severe and potentially life-threatening manifestation of Type I hypersensitivity reactions.

A.. Type II hypersensitivity reactions occur when the immune system targets antigens on the body's own cells, leading to cell destruction or dysfunction.

B. Autoimmune responses involve the immune system mistakenly attacking the body's own tissues and organs, leading to inflammation and tissue damage.

D. Cell-mediated hypersensitivity reactions involve the activation of T cells and the release of cytokines, resulting in inflammation and tissue damage. Examples include delayed-type hypersensitivity reactions such as contact dermatitis or tuberculin skin testing reactions.

A. Raise hands above the head to expand the diaphragm. B. Increase breathing rate for a full 30 seconds. C. Draw air in through nose and exhale slowly through pursed lips. D. Lay down on each side with knees bent and breathe from abdomen.

Correct Answer is C

Explanation

C. This technique, known as pursed lip breathing, can help improve gas exchange by slowing down the respiratory rate, promoting more efficient exhalation, and reducing air trapping in the lungs.

A. While raising the hands above the head can help expand the chest and improve lung expansion to some extent, it may not be as effective as pursed lip breathing in improving gas exchange or alleviating dyspnea.

B. Increasing the breathing rate for a full 30 seconds may not be beneficial and could potentially worsen dyspnea, especially in individuals with emphysema or other respiratory conditions.

D. While changing positions and focusing on diaphragmatic breathing can be helpful techniques in managing dyspnea, lying down on each side with knees bent may not be practical for a client who is ambulatory and experiencing mild dyspnea after ambulation.
