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?

Vitamin C

Oxalates

Fiber

Vitamin A

Answer and Explanation

The Correct Answer is A

A. 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, found in foods like spinach and rhubarb, can inhibit iron absorption by binding to iron and reducing its availability.
C. 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 does not have a direct role in the absorption of iron, though it is essential for overall health.

Correct Answer is B

Explanation

A. Differences in upper and lower lung sounds are not indicative of atrial fibrillation but may suggest other conditions such as fluid accumulation or pneumonia.
B. A difference between apical and radial pulses, known as pulse deficit, can indicate atrial fibrillation due to the irregular and often rapid heartbeat that may not always produce a palpable radial pulse.
C. Differences between oral and axillary temperatures are not relevant to the assessment of atrial fibrillation but could indicate issues with measurement accuracy.
D. Different blood pressures in the upper limbs might suggest vascular issues but are not specific indicators of atrial fibrillation.

A. Mantoux test B. Chest x-ray C. Sputum culture for acid-fast bacillus D. Sputum smear

Correct Answer is C

Explanation

A. The Mantoux test (TB skin test) is used for screening and indicates exposure to TB but cannot confirm active disease.
B. 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. 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. A sputum smear can detect acid-fast bacilli but is less definitive than a culture, which confirms the diagnosis.
