A nurse in a clinic is caring for a client who came to be tested for tuberculosis (TB) after a close family member tested positive. The nurse should know that which of the following is a diagnostic tool used to screen for TB?
- A. Sputum culture for acid-fast bacillus (AFB)
- B. Mantoux skin test
- C. BCG vaccine
- D. Chest X-ray
Correct Answer: B
Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

A nurse is preparing for the hospital admission of a client who is suspected to have active tuberculosis (TB). Which of the following precautions should the nurse plan to implement to safely care for this client?
- A. Staff and visitors should wear gowns, masks, and gloves while in the client's room.
- B. The client should be placed in a private room with a special ventilation system.
- C. The client may be placed in a room with other clients who require droplet isolation precautions.
- D. The protocol for donning and removing personal protective equipment before entering or leaving the room of a client with TB is different than for clients who are in other types of isolation.
Correct Answer: B
Rationale: When caring for a client suspected of having active tuberculosis (TB), it is essential to place the client in a private room with a special ventilation system to prevent the spread of TB bacteria to others. Choice A is incorrect because staff and visitors should wear respiratory protection, not just gowns, masks, and gloves. Choice C is incorrect as clients with TB should not be placed in a room with other clients, as they need to be isolated to prevent transmission. Choice D is incorrect because the protocol for donning and removing personal protective equipment for clients with TB is similar to other types of isolation, focusing on proper infection control measures.
A provider is discharging a client with a prescription for home oxygen therapy. Client and family teaching by the nurse should include all of the following instructions except?
- A. Cleanse the mask or collar with soapy water every other day.
- B. Ensure that the straps on the mask are secure but not too tight.
- C. Apply petroleum jelly around and inside the nares.
- D. Post 'no smoking' warning signs at home in a prominent location.
Correct Answer: C
Rationale: When providing instructions for home oxygen therapy, it is important to ensure safety and proper care. Choices A, B, and D are all essential instructions for the client and family. Choice C, 'Apply petroleum jelly around and inside the nares,' is incorrect. Petroleum jelly should not be used near oxygen sources as it is flammable and can increase the risk of fire hazard. Therefore, this instruction should not be included in the teaching.
A client with chronic obstructive pulmonary disease (COPD expresses difficulty in bringing up bronchial secretions. Which action should the nurse take to help the client with tenacious bronchial secretions?
- A. Maintaining a semi-Fowler's position as much as possible
- B. Administering oxygen via nasal cannula at 2 L per min
- C. Helping the client select a low-salt diet
- D. Encouraging the client to drink eight glasses of water daily
Correct Answer: D
Rationale: Encouraging the client to drink eight glasses of water daily is the most appropriate action to help with tenacious bronchial secretions in COPD. Increased fluid intake can help in thinning the mucus, making it easier for the client to cough up and clear secretions. This addresses the client's difficulty in bringing up bronchial secretions. Maintaining a semi-Fowler's position can aid in breathing but does not directly address the issue of clearing secretions. Administering oxygen may be necessary for COPD, but it does not specifically target the tenacious secretions. Selecting a low-salt diet can be helpful in managing COPD in general, but it does not directly address the client's current concern of clearing bronchial secretions.
When caring for a client with COPD, which intervention should the nurse include in the care plan?
- A. Restrict the client's fluid intake to less than 2 L/day.
- B. Encourage the client to use the upper chest for respiration.
- C. Have the client use the early-morning hours for exercise and activity.
- D. Instruct the client to use pursed-lip breathing.
Correct Answer: D
Rationale: The correct answer is to instruct the client to use pursed-lip breathing. This technique helps improve breathing efficiency by keeping the airways open during exhalation and reducing air trapping. Restricting fluid intake to less than 2 L/day is not appropriate for a client with COPD, as they need adequate hydration. Using the upper chest for respiration is incorrect as it promotes shallow breathing, which is not ideal for COPD patients. While exercise is beneficial, early-morning hours may not be the best time for clients with COPD due to increased respiratory distress in the morning.
A client hospitalized with deep vein thrombosis has been on IV heparin for 5 days. The provider prescribes oral warfarin (Coumadin) without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following is an appropriate nursing response?
- A. The Coumadin takes several days to work, so the IV heparin will be used until the Coumadin reaches a therapeutic level.
- B. I will call the provider to get a prescription for discontinuing the IV heparin today
- C. Both heparin and Coumadin work together to dissolve the clots.
- D. The IV heparin increases the effects of the Coumadin and decreases the length of your hospital stay.
Correct Answer: A
Rationale: The correct answer is, 'The Coumadin takes several days to work, so the IV heparin will be used until the Coumadin reaches a therapeutic level.' Warfarin (Coumadin) is an oral anticoagulant that takes time to reach its full effect, typically a few days. In the meantime, IV heparin is used to provide immediate anticoagulation until the Coumadin levels become therapeutic. Option B is incorrect because discontinuing the IV heparin abruptly without reaching a therapeutic level with Coumadin can increase the risk of clot formation. Option C is incorrect because heparin and Coumadin do not work together to dissolve clots; they both have anticoagulant effects but work differently. Option D is incorrect because IV heparin does not directly increase the effects of Coumadin; they have different mechanisms of action.
