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: Apply petroleum jelly around and inside the nares
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 nurse at a provider's office receives a phone call from a client who reports unrelieved chest pain after taking a nitroglycerin (Nitrostat) tablet 5 minutes ago. Which of the following is an appropriate response by the nurse?

• A. Tell the client to take an aspirin.
• B. Instruct the client to call 911.
• C. Have the client take another nitroglycerin tablet in 15 minutes.
• D. Advise the client to come to the office.

Correct Answer: Instruct the client to call 911.
Rationale: In this scenario, the client reporting unrelieved chest pain after taking a nitroglycerin tablet could be indicative of a serious cardiac event. Instructing the client to call 911 is the most appropriate response because immediate medical attention is necessary for chest pain that is not relieved by nitroglycerin. Telling the client to take an aspirin (Choice A) may not address the urgency of the situation, and aspirin might not be appropriate depending on the client's medical history. Having the client take another nitroglycerin tablet (Choice C) without relief could lead to overdosage. Advising the client to come to the office (Choice D) is not the best course of action when dealing with a potential cardiac emergency that requires immediate intervention.

A client prescribed home oxygen therapy is receiving discharge teaching from a nurse. Which statement by the client indicates a need for further teaching?

• A. I will be able to tell the amount of oxygen being delivered by looking at the flowmeter.
• B. I should contact my doctor if I notice a decrease in my ability to concentrate.
• C. I will ensure that visitors smoke outside.
• D. I should see a frosty buildup on the tank when I refill my portable oxygen.

Correct Answer: A: "I will be able to tell the amount of oxygen being delivered by looking at the flowmeter."
Rationale: The correct answer is A. The client's statement indicates a need for further teaching because the flowmeter indicates the flow rate of oxygen, not the total amount of oxygen being delivered. Choices B, C, and D demonstrate understanding of safety measures and indications for seeking medical attention in relation to home oxygen therapy, making them appropriate statements.

A client with peripheral arterial disease (PAD) is experiencing muscle pain or cramping during physical activity that resolves with rest. Which of the following symptoms is typically the initial reason clients with PAD seek medical attention?

• A. Intermittent claudication
• B. Dependent rubor
• C. Rest pain
• D. Foot ulcers

Correct Answer: Intermittent claudication
Rationale: The correct answer is Intermittent claudication. Intermittent claudication, which manifests as muscle pain or cramping during physical activity that improves with rest, is typically the initial reason clients with PAD seek medical attention. Dependent rubor, rest pain, and foot ulcers are more advanced symptoms of PAD and are not usually the initial reasons for seeking medical care.

A client who is HIV-positive, has pneumonia and is not responding to antibiotic therapy may have active pulmonary tuberculosis (TB) due to exposure history and symptoms of night sweats and hemoptysis. Which test is the most reliable to confirm the diagnosis of active pulmonary TB?

• A. Chest x-ray
• B. Presence of bronchophony
• C. Mantoux test
• D. Sputum culture for acid-fast bacillus

Correct Answer: Sputum culture for acid-fast bacillus
Rationale: The correct answer is D: Sputum culture for acid-fast bacillus. The most reliable test to confirm the diagnosis of active pulmonary TB is the sputum culture for acid-fast bacillus. This test helps identify the presence of Mycobacterium tuberculosis, the causative agent of TB, in the sputum. Chest x-rays can show characteristic findings of TB but are not as reliable as sputum cultures for confirmation. Bronchophony is a test for assessing vocal resonance and is not specific for TB diagnosis. The Mantoux test is a screening test for TB exposure but cannot confirm active disease.
