Nursing Elites

1. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?

• A. Encourage the patient to increase her fluid intake to 200 ml every 2 hours
• B. Place a humidifier in the patient’s room
• C. Continue administering oxygen by high humidity face mask
• D. Perform chest physiotherapy on a regular schedule

Correct answer: D

Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.

2. A client has a new prescription for heparin therapy. Which of the following statements by the client should indicate an immediate concern for the nurse?

• A. ''I am allergic to morphine.''
• B. ''I take antacids several times a day.''
• C. ''I had a blood clot in my leg several years ago.''
• D. ''It hurts to take a deep breath.''

Correct answer: B

Rationale: The correct answer is the statement 'I take antacids several times a day.' Antacids can alter the absorption of heparin, potentially affecting its effectiveness and increasing the risk of clot formation. This is a significant concern as it can impact the therapeutic outcome of heparin therapy. The other statements are not directly related to potential complications or interactions with heparin therapy.

3. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

4. What is the meaning of PRN?

• A. When advice
• B. Immediately
• C. When necessary
• D. Now

Correct answer: C

Rationale: The correct meaning of PRN is 'when necessary.' The abbreviation 'PRN' comes from the Latin term 'pro re nata,' which is commonly used in medical contexts to indicate that a medication should be taken as needed, not at scheduled intervals. Choice A ('When advice') is incorrect as PRN does not refer to seeking advice. Choice B ('Immediately') is incorrect as PRN does not imply urgency. Choice D ('Now') is incorrect as PRN does not mean 'immediate' but rather 'as needed.' Therefore, the correct answer is C, 'When necessary.'

5. Which of the following is the correct abbreviation for drops?

• A. Gtt.
• B. Gtts.
• C. Dp.
• D. Dr.

Correct answer: A

Rationale: The correct abbreviation for drops in medical terminology is 'Gtt.' It is derived from the Latin word 'guttae,' meaning drops. The abbreviation 'Gtts.' (Choice B) is incorrect as it adds an unnecessary 's.' Choices C and D, 'Dp.' and 'Dr.,' are not standard abbreviations for drops in medical contexts, making them incorrect.
