A patient has been diagnosed with tuberculosis and is to begin antitubercular therapy with isoniazid, rifampin, and ethambutol. Which actions are appropriate for the nurse to do? (Select all that apply.)

Correct Answer: A

Rationale: Ethambutol can cause optic neuritis, so periodic eye examinations are essential. Taking medications with meals can help reduce gastrointestinal side effects. Antacids should be avoided as they can interfere with drug absorption. Numbness and tingling of the hands or feet may indicate peripheral neuropathy, a side effect of isoniazid, and should be reported promptly.

Correct Answer: C

Rationale: Phentolamine is used during surgery for pheochromocytoma in children. Prazosin is used to treat hypertension in children. Propranolol and guanethidine are not indicated for use in children with a pheochromocytoma. The nurse should understand the indications for phentolamine to ensure safe and effective administration.

Correct Answer: C

Rationale: The most accurate response by the nurse is "This drug is the first medication your health care provider will use to treat your angina." This response provides important information to the patient that Ranexa is specifically used to treat angina. It also indicates that Ranexa is often the initial medication chosen for treating this condition, providing reassurance to the patient about the appropriateness of the prescribed drug.

Correct Answer: D

Rationale: Respiratory alkalosis results from excessive CO2 loss, raising pH. Hyperventilation causes this, common in anxiety or hypoxia. Hypotension and hypertension affect circulation, not breathing rate. Hypoventilation causes acidosis. D aligns with acid-base physiology, making it correct.

Correct Answer: A

Rationale: Oxytocin induces labor by stimulating uterine contractions, but excessive use can cause hyperstimulation, leading to continuous, sustained contractions . This risks uterine rupture or fetal distress, necessitating immediate cessation of the infusion to protect mother and baby. Transition is a labor stage, not a reason to stop unless complications arise. Strong contractions are expected, and regular contractions every 2-3 minutes are normal for labor induction. The nurse stops the infusion for sustained contractions due to their potential for catastrophic outcomes, making choice A the most likely trigger based on oxytocin's safety profile.
