1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?
- A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
- B. Circulatory overload due to hypervolemia
- C. Respiratory excitement
- D. Inhibition of the respiratory hypoxic stimulus
Correct answer: D
Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
2. A healthcare professional is reviewing laboratory data for a client who has chronic kidney disease. Which of the following findings should the healthcare professional expect?
- A. Increased creatinine.
- B. Increased hemoglobin.
- C. Increased bicarbonate.
- D. Increased calcium.
Correct answer: A
Rationale: In chronic kidney disease, the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of creatinine. Creatinine levels are commonly elevated in individuals with impaired kidney function, making it a key indicator of kidney health. Therefore, an increased creatinine level would be an expected finding in a client with chronic kidney disease.
3. How many liters are equal to 1800 ml?
- A. 1.8
- B. 18000
- C. 180
- D. 2800
Correct answer: A
Rationale: To convert milliliters (ml) to liters, divide by 1000 since 1 liter is equal to 1000 ml. Therefore, 1800 ml is equal to 1800/1000 = 1.8 liters. Choice A (1.8) is correct. Choice B (18000) is incorrect as it equates to 18000 liters, not 1.8 liters. Choice C (180) is incorrect as it represents 180 liters, not 1.8 liters. Choice D (2800) is incorrect as it does not reflect the conversion of 1800 ml to liters.
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. A client is being instructed on how to perform pursed-lip breathing. Which of the following should be included in the plan of care?
- A. Take quick breaths upon inhalation.
- B. Place your hand over your stomach.
- C. Take a deep breath in through your nose.
- D. Puff your cheeks upon exhalation.
Correct answer: C
Rationale: Pursed-lip breathing is a breathing technique that involves inhaling slowly through the nose and exhaling gently through pursed lips. This technique helps improve breathing efficiency and can be beneficial for individuals with respiratory conditions. Instructing the client to take a deep breath in through the nose is essential for proper execution of pursed-lip breathing, making choice C the correct answer.
