Which interventions does the nurse implement when providing care for a patient who is admitted for the treatment of active tuberculosis? (Select All that Apply.)
Places a surgical mask on the patient to transport to radiology.
Places the patient on droplet precautions.
Wears a surgical mask when providing patient care.
Places the patient in a private, negative airflow room.
Wears eye protection when collecting sputum samples.
Correct Answer : A,D,E
A. It is important to place a surgical mask on the patient when transporting them to minimize the risk of spreading TB droplets in the environment. This practice helps reduce transmission during transport.
B. TB is primarily transmitted via airborne particles, not droplets. Therefore, patients with active TB should be placed on airborne precautions, not droplet precautions. Airborne precautions include the use of specialized masks and a negative airflow room to prevent the spread of infectious aerosols.
C. While a surgical mask is not adequate for protecting healthcare workers from TB, they should wear a fitted N95 respirator or a powered air-purifying respirator (PAPR) when providing care to a patient with active TB. A surgical mask does not filter out the small particles that can carry TB bacteria.
D. Patients with active TB should be placed in a private room that has negative pressure ventilation. This design helps prevent airborne TB particles from escaping into other areas of the healthcare facility, protecting other patients and staff.
E. Eye protection is recommended when collecting sputum samples from a patient with active TB, as it helps protect against potential splashes of respiratory secretions that may contain infectious droplets. This is particularly important during procedures that may aerosolize the bacteria.

Correct Answer is C
Explanation
A. This is the mechanism of action of angiotensin-converting enzyme (ACE) inhibitors, not calcium channel blockers. ACE inhibitors work by preventing the formation of angiotensin II, a hormone that causes blood vessels to constrict.
B. Calcium channel blockers do not directly affect angiotensin.
C. This is the correct mechanism of action of calcium channel blockers. By blocking the influx of calcium ions into smooth muscle cells, these medications cause the blood vessels to relax and dilate, lowering blood pressure.
D. Calcium channel blockers work by relaxing the smooth muscle of the blood vessels, which decreases their ability to contract and cause vasoconstriction.
Correct Answer is C
Explanation
A. While yogurt is a nutritious food, it is not a significant source of iron.
B. Oranges are rich in vitamin C, which can help the body absorb iron from other foods. However, they are not a significant source of iron themselves.
C. Red meat, such as beef, lamb, and pork, is an excellent source of heme iron, which is easily absorbed by the body. This makes red meat a highly recommended food for people with iron deficiency.
D. Cashews are a good source of plant-based iron, but they also contain phytates, which can interfere with iron absorption. Therefore, while cashews can contribute to iron intake, they may not be as effective as red meat in addressing iron deficiency.
