The nurse obtains the following arterial blood gas results on a client: pH 7.2, PaO2 88 mmHg, PaCO2 40 mmHg, HCO3 19 mEq/L. Which acid-base imbalance is the client experiencing?

Respiratory alkalosis

Metabolic alkalosis

Respiratory acidosis

Metabolic acidosis

Answer and Explanation

The Correct Answer is D

Choice A reason: Respiratory alkalosis is not the correct answer. Respiratory alkalosis is a condition where the blood pH is high (above 7.45) due to low carbon dioxide levels (below 35 mmHg) caused by hyperventilation. The client's blood pH is low (7.2) and the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory alkalosis.

Choice B reason: Metabolic alkalosis is not the correct answer. Metabolic alkalosis is a condition where the blood pH is high (above 7.45) due to high bicarbonate levels (above 26 mEq/L) caused by excessive loss of acids or intake of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which does not indicate metabolic alkalosis.

Choice C reason: Respiratory acidosis is not the correct answer. Respiratory acidosis is a condition where the blood pH is low (below 7.35) due to high carbon dioxide levels (above 45 mmHg) caused by hypoventilation. The client's blood pH is low (7.2) but the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory acidosis.

Choice D reason: This is the correct answer. Metabolic acidosis is a condition where the blood pH is low (below 7.35) due to low bicarbonate levels (below 22 mEq/L) caused by excessive production or intake of acids or loss of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which indicates metabolic acidosis.

Correct Answer is D

Explanation

Choice A reason: This is incorrect. Traveling to cities where the oxygen level is lower, such as high-altitude areas, can trigger a sickle cell crisis by reducing the amount of oxygen in the blood. People with sickle cell anemia should avoid such places or take precautions such as using supplemental oxygen¹².

Choice B reason: This is incorrect. Strenuous exercise does not prevent sickle cell crisis, but rather can cause it by increasing the body's oxygen demand and dehydration. People with sickle cell anemia should avoid overexertion and rest frequently during physical activity¹³.

Choice C reason: This is incorrect. Flying on commercial airlines is not prohibited for people with sickle cell anemia, as long as they stay hydrated and avoid alcohol and caffeine. However, some people may need to use supplemental oxygen during flights, especially if they have a history of acute chest syndrome or pulmonary hypertension¹⁴.

Choice D reason: This is correct. Drinking plenty of fluids when outside in hot weather is important for people with sickle cell anemia, as dehydration can cause the red blood cells to sickle and block blood vessels. Staying hydrated can help prevent or reduce the severity of sickle cell crises¹⁵.

A. Has gained 2 pounds and has pink buccal mucosa B. No longer has paresthesia of the hands and feet C. Realizes eating more iron fortified cereals D. Has stopped drinking any alcoholic beverages

Correct Answer is B

Explanation

Choice A reason: While gaining weight and having pink buccal mucosa can be signs of overall improved health, they are not specific indicators of effective treatment for vitamin B12 deficiency¹².

Choice B reason: Paresthesia (a sensation of tingling, tickling, pricking, or burning of a person's skin) of the hands and feet is a common symptom of vitamin B12 deficiency¹². If the client no longer has this symptom, it could indicate that the treatment for vitamin B12 deficiency has been effective¹².

Choice C reason: Eating more iron-fortified cereals can contribute to overall nutritional health, but it's not directly related to the treatment of vitamin B12 deficiency¹².

Choice D reason: While stopping alcohol consumption can improve overall health, it's not a specific indicator of effective treatment for vitamin B12 deficiency¹²..
