A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
A. Vitamin C
Vitamin C enhances the absorption of non-heme iron from plant-based sources by converting iron to a more absorbable form. Including vitamin C-rich foods with iron-rich meals can improve iron uptake.
B. Oxalates
Oxalates, found in foods like spinach and rhubarb, can inhibit iron absorption by binding to iron and reducing its availability.
C. Fiber
Fiber, while beneficial for digestive health, does not enhance iron absorption and can, in some cases, inhibit it by binding to minerals.
D. Vitamin A
Vitamin A does not have a direct role in the absorption of iron, though it is essential for overall health.

nurse is caring for the client who has Ménière's disease and asks if he is allowed to ambulate independently. Which of the following responses should the nurse make?
A. "Please ring for assistance when you wish to get out of bed."
Clients with Ménière's disease may experience dizziness and balance issues, so it is important to ensure safety by asking them to ring for assistance when moving around to prevent falls or injuries.
B. "We will have to get a prescription from your provider."
A prescription from the provider is not typically required for ambulation; instead, safety measures should be in place.
C. "Yes, you are free to move around as you wish."
Allowing free movement without assistance may increase the risk of falls due to balance problems associated with Ménière's disease.
D. "No, you are on strict bedrest and must not be up."
Strict bedrest is generally not necessary unless specifically indicated by the provider; assistance and safety measures are more appropriate.

A nurse is caring for a client who has a history of exposure to TB and symptoms of night sweats and hemoptysis. Which of the following tests should the nurse realize is the most reliable to confirm the diagnosis of active pulmonary TB?
A. Mantoux test
The Mantoux test (TB skin test) is used for screening and indicates exposure to TB but cannot confirm active disease.
B. Chest x-ray
A chest x-ray can show signs suggestive of TB, such as lung lesions, but it does not confirm the presence of the bacteria.
C. Sputum culture for acid-fast bacillus
A sputum culture for acid-fast bacillus is the most reliable test for confirming active pulmonary TB as it identifies the presence of Mycobacterium tuberculosis in the sputum.
D. Sputum smear
A sputum smear can detect acid-fast bacilli but is less definitive than a culture, which confirms the diagnosis.
