An RN is caring for a patient with Tuberculosis who is to receive a new prescription for Isoniazid (INH). The nurse knows that INH can cause peripheral neuropathy. To help prevent this from happening, the nurse can ask the provider for:
Phenazopyridine
Phentolamine
Vitamin B6 (Pyridoxine)
Pyrazinamide
The Correct Answer is C
A. This medication is used primarily to relieve urinary tract discomfort and does not have any role in preventing peripheral neuropathy associated with INH. It is not relevant in this context.
B. Phentolamine is an alpha-adrenergic antagonist used to treat hypertension and manage pheochromocytoma. It has no association with preventing peripheral neuropathy related to INH and is not appropriate for this patient.
C. Isoniazid can cause peripheral neuropathy by interfering with the metabolism of pyridoxine (Vitamin B6). Administering pyridoxine can help prevent this side effect by replenishing the vitamin and supporting nerve health.
D. Pyrazinamide is another anti-tuberculosis medication that works alongside INH. While it is effective for tuberculosis, it does not prevent peripheral neuropathy and may even have its own side effects.

Correct Answer is B
Explanation
A. A positive ketone result indicates the presence of ketones in the urine, which can occur in conditions such as diabetes, fasting, or starvation. It is not indicative of a UTI.
B. A positive leukocyte esterase test indicates the presence of white blood cells (WBCs) in the urine, suggesting inflammation or infection, commonly associated with a UTI. This enzyme is released by WBCs, making it a key marker for infections.
C. The presence of crystals in the urine can indicate various conditions, including kidney stones or metabolic disorders, but it is not a specific marker for a UTI.
D. Hyaline casts may appear in the urine in response to dehydration or concentrated urine but are not specific to urinary tract infections. They can be seen in various renal conditions and do not indicate infection.
Correct Answer is B
Explanation
A. While it’s important to provide reassurance, this option does not directly address the acute symptoms of respiratory distress and hypotension. Monitoring blood pressure is essential, but immediate action to treat the underlying issue is more critical.
B. This is the priority intervention in the case of suspected anaphylaxis. Epinephrine acts quickly to counteract severe allergic reactions, relieving bronchospasm, increasing heart rate, and raising blood pressure. Given the patient's wheezing and hypotension, administering epinephrine is crucial.
C. Administering oxygen can be beneficial, especially if the patient is experiencing respiratory distress. However, it does not address the potential anaphylactic reaction or the drop in blood pressure directly. It should be part of the management but not the priority.
D. Elevating the head of the bed can help improve breathing, especially if the patient is in respiratory distress. However, this action alone does not address the potential life-threatening aspects of anaphylaxis.
