When educating a patient with tuberculosis (TB) about medication adherence, which of the following instructions is most important?

if you miss a dose, double the next dose to catch up.

Stop taking medications as soon as symptoms improve to avoid side effects.

Take your medications at the same time every day to maintain consistent drug levels.

it's okay to skip doses on weekends when symptoms are less noticeable.

Answer and Explanation

The Correct Answer is C

Rationale:
A. Doubling the next dose after missing one is unsafe and increases the risk of toxicity.
B. TB treatment must continue for the entire prescribed duration (often 6–12 months); stopping early can lead to relapse and drug resistance.
C. Taking medications at the same time every day is the most important instruction because it maintains consistent therapeutic drug levels, ensures effectiveness, and reduces the risk of resistance.
D. Skipping doses, even on weekends, decreases treatment effectiveness and increases the risk of multidrug-resistant TB.

Correct Answer is B

Explanation

Rationale:
A. Deep breathing exercises would help correct respiratory acidosis by eliminating CO₂, but this client has metabolic acidosis.
B. The ABG shows metabolic acidosis (low pH 7.32, low HCO₃⁻ 16, low PaCO₂ as partial compensation). The priority treatment may include IV sodium bicarbonate in severe cases to buffer excess acid.
C. Mechanical ventilation is indicated for respiratory failure, not metabolic acidosis.
D. Oxygen therapy is unnecessary since the PaO₂ is normal (85 mm Hg).

A. Kussmaul respirations B. Peripheral edema C. Hypertension D. Bradycardia

Correct Answer is A

Explanation

Rationale:
A. Kussmaul respirations are deep, rapid breathing that occur as a compensatory mechanism in metabolic acidosis (commonly seen in diabetic ketoacidosis). The body attempts to blow off excess CO₂ to reduce acidity.
B. Peripheral edema is not a feature of metabolic acidosis; it is usually related to fluid overload or right-sided heart failure.
C. Hypertension is not an expected finding; in fact, metabolic acidosis may be associated with hypotension due to vasodilation and dehydration in diabetic ketoacidosis.
D. Bradycardia is not typical; severe acidosis may cause arrhythmias, but tachycardia is more common initially as the body compensates.
