Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?

• A. Use oxygen at the highest flow rate tolerated
• B. Avoid wearing oxygen during physical activity
• C. Do not smoke while using oxygen
• D. Store oxygen tanks in a cool, dark place

Correct answer: C

Rationale: The correct answer is C: 'Do not smoke while using oxygen.' Smoking while using oxygen can lead to a serious fire hazard, as oxygen supports combustion. This instruction is crucial to prevent potential harm to the client. Choices A, B, and D are incorrect. Using oxygen at the highest flow rate tolerated can be harmful, avoiding wearing oxygen during physical activity may limit the client's mobility unnecessarily, and storing oxygen tanks in a cool, dark place, although important, is not as critical as the instruction to avoid smoking while using oxygen.

2. A client with a diagnosis of chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?

• A. Use oxygen at the highest flow rate tolerated.
• B. Do not smoke while using oxygen.
• C. Avoid wearing the oxygen during physical activity.
• D. Store oxygen tanks in a cool, dark place.

Correct answer: B

Rationale: The most important instruction the nurse should provide to a client with COPD receiving home oxygen therapy is not to smoke while using oxygen. Smoking near oxygen can cause a fire or explosion due to the flammable nature of oxygen. Choice A is incorrect because using oxygen at the highest flow rate tolerated without medical supervision can be harmful. Choice C is the correct answer as wearing oxygen during physical activity can increase the risk of oxygen combustion. Choice D is not the most important instruction; while storing oxygen tanks properly is essential, the immediate safety concern is the risk of fire due to smoking near oxygen.

3. A client with a diagnosis of hypertension is prescribed a thiazide diuretic. Which potential side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypoglycemia

Correct answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Thiazide diuretics commonly cause potassium loss, which can lead to hypokalemia. Monitoring potassium levels is essential when a client is taking thiazide diuretics to prevent complications such as cardiac dysrhythmias. Choices A, B, and D are incorrect. Hyperkalemia (choice A) is an elevated level of potassium, which is not typically associated with thiazide diuretics. Hypernatremia (choice B) is an elevated level of sodium, and hypoglycemia (choice D) is low blood sugar, neither of which are directly linked to thiazide diuretic use.

4. A client is being treated for dehydration. Which clinical finding would indicate that treatment is effective?

• A. Dry mucous membranes
• B. Increased urine output
• C. Tachycardia
• D. Hypotension

Correct answer: B

Rationale: The correct answer is B: Increased urine output. When a client is being treated for dehydration, increased urine output is a positive indication that the treatment is effective. This signifies that the body is beginning to rehydrate and eliminate excess fluid. Choices A, C, and D are incorrect because dry mucous membranes, tachycardia, and hypotension are all associated with dehydration and would not be signs of effective treatment.

5. What is the primary purpose of a chest tube in a client's care?

• A. To drain air and fluid from the pleural space
• B. To prevent infection in the thoracic cavity
• C. To assist with lung expansion
• D. To monitor intrathoracic pressure

Correct answer: A

Rationale: The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.
