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

Answer and Explanation

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 C

Explanation

A. While obtaining a sputum culture is important for identifying the causative organism and guiding antibiotic therapy, it is not an immediate priority. Delaying this test briefly for critical interventions (like oxygen administration) is acceptable, as stabilizing the patient's oxygen levels is more urgent.
B. Educating the patient about vaccination is important for long-term health and prevention of future respiratory infections. However, it does not address the current situation and does not provide immediate benefit for the acute episode of pneumonia.
C. The patient has a SpO2 of 91%, which indicates hypoxemia (low oxygen levels in the blood). In pneumonia, adequate oxygenation is crucial to prevent further respiratory distress and potential complications. Administering oxygen therapy will help improve the oxygen saturation and support the patient’s respiratory function, making this the highest priority intervention.
D. While antibiotics are essential for treating bacterial pneumonia, they may take time to exert their effects. In this acute scenario, the immediate need is to ensure the patient is adequately oxygenated. After oxygen is administered, antibiotics can be given promptly.

A. Chronic blood loss B. Liver problems C. Decreased folic acid absorption in the gut D. Low dietary intake of Iron

Correct Answer is C

Explanation

A. Chronic blood loss is one of the most common causes of iron deficiency anemia. Conditions such as gastrointestinal bleeding (e.g., from ulcers, polyps, or cancer), heavy menstrual periods, or chronic blood donation can lead to a gradual loss of iron, resulting in anemia.
B. While liver problems can lead to various blood disorders, they are not a direct cause of iron deficiency anemia. Liver disease can affect iron metabolism and storage but does not typically cause iron deficiency unless accompanied by chronic blood loss or malnutrition.
C. Decreased folic acid absorption leads to folate deficiency anemia, not iron deficiency anemia. While folate is important for red blood cell production, it does not directly influence iron levels. This option is not a common cause of iron deficiency anemia.
D. Low dietary intake of iron is a well-known cause of iron deficiency anemia. Diets lacking in iron-rich foods (such as red meat, beans, and fortified cereals) can lead to insufficient iron stores and subsequent anemia.
