A client comes into the emergency room with complaints of an enlarged tongue. The tongue appears smooth and beefy red in color. The nurse also observes a 5-cm incision on the upper left quadrant of the abdomen. When questioned, the patient states, "I had a partial gastrostomy 2 years ago." Based on this information, the nurse attributes these symptoms to which of the following problems?
Vitamin A deficiency
Folic acid deficiency
Vitamin B12 deficiency
Vitamin C deficiency
The Correct Answer is C
A. Vitamin A Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Vitamin A deficiency is not typically associated with an enlarged tongue. It is more commonly linked to night blindness and skin issues.
B. Folic Acid Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Folic acid deficiency can lead to megaloblastic anemia and glossitis (inflammation of the tongue), which may present as an enlarged, smooth, and red tongue.
C. Vitamin B12 Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Vitamin B12 deficiency can cause pernicious anemia and glossitis, resulting in an enlarged, smooth, and red tongue.
D. Vitamin C Deficiency:
Symptoms: Not typically associated with an enlarged tongue.
Relevance: Vitamin C deficiency is more commonly associated with symptoms like scurvy, which includes bleeding gums, joint pain, and skin issues, but not specifically an enlarged tongue.

Correct Answer is D
Explanation
A. It is rapidly absorbed, has a fast onset of action:
Explanation: This statement is incorrect. Glargine (Lantus) actually has a slow onset of action and a prolonged duration of action. It is formulated to provide a steady level of insulin in the body over an extended period.
B. Administer the total daily dosage in two doses:
Explanation: This is not the recommended administration for glargine. It is typically administered once daily to provide basal insulin coverage over a 24-hour period.
C. Draw up the drug first, then add regular insulin:
Explanation: Mixing glargine with other insulins is not recommended. Glargine should be administered separately to maintain its extended duration of action. It should not be mixed with other insulins in the same syringe.
D. Do not mix with other insulins:
Explanation: This is the correct statement. Glargine should not be mixed with other insulins. It should be administered alone to maintain its "peakless" basal coverage. Mixing it with other insulins could alter its pharmacokinetics and compromise its effectiveness.
Correct Answer is A
Explanation
A. Metabolic Alkalosis:
pH: Elevated (alkalotic).
PaCO2: Normal or slightly decreased (compensation may or may not be present).
HCO3: Elevated.
Explanation: Metabolic alkalosis is characterized by an excess of bicarbonate (HCO3) in the blood, leading to an elevated pH. In this case, the elevated pH and HCO3 levels suggest that the primary imbalance is metabolic alkalosis.
B. Respiratory Alkalosis:
pH: Elevated (alkalotic).
PaCO2: Decreased (due to hyperventilation, which blows off CO2).
HCO3: Normal or slightly decreased (compensation).
Explanation: Respiratory alkalosis is characterized by low levels of carbon dioxide (PaCO2) due to hyperventilation. However, in the provided ABG, the PaCO2 is not significantly decreased, suggesting that respiratory alkalosis is not the primary issue.
C. Respiratory Acidosis:
pH: Decreased (acidotic).
PaCO2: Increased (due to inadequate ventilation).
HCO3: Normal or slightly elevated (compensation).
Explanation: Respiratory acidosis is characterized by an increase in carbon dioxide (PaCO2) levels. In this case, the PaCO2 is within the normal range, indicating that respiratory acidosis is not the primary problem.
D. Metabolic Acidosis:
pH: Decreased (acidotic).
PaCO2: Normal or slightly decreased (compensation).
HCO3: Decreased.
Explanation: Metabolic acidosis is characterized by a decrease in bicarbonate (HCO3) levels. In this ABG, the HCO3 is elevated, ruling out metabolic acidosis as the primary issue.
