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.

What is the most common injury among elderly persons?
- A. Atherosclerotic changes in the blood vessels
- B. Increased incidence of gallbladder disease
- C. Urinary Tract Infection
- D. Hip fracture
Correct Answer: D
Rationale: Hip fracture is the most common injury among elderly persons. As people age, their bones become more fragile, making them more susceptible to hip fractures, often resulting from falls. These fractures can significantly impact an elderly person's quality of life and mobility, making them a significant concern in geriatric care.
Which of the following statements is incorrect about a patient with dysphagia?
- A. The patient will find pureed or soft foods, such as custards, easier to swallow than water
- B. Fowler's or semi Fowler's position reduces the risk of aspiration during swallowing
- C. The patient should always feed himself
- D. The nurse should perform oral hygiene before assisting with feeding
Correct Answer: C
Rationale: The incorrect statement is that 'The patient should always feed himself.' Patients with dysphagia may require assistance with feeding due to difficulty in swallowing safely. It is essential to provide appropriate support and supervision during meal times to prevent complications such as aspiration or inadequate nutrition intake.
The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?
- A. 5 gtt/minute
- B. 13 gtt/minute
- C. 25 gtt/minute
- D. 50 gtt/minute
Correct Answer: C
Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour · 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.
What is the correct sequence for assessing the abdomen?
- A. Tympanic percussion, measurement of abdominal girth, and inspection
- B. Assessment for distention, tenderness, and discoloration around the umbilicus
- C. Percussion, palpation, and auscultation
- D. Auscultation, percussion, and palpation
Correct Answer: D
Rationale: The correct sequence for assessing the abdomen is auscultation, percussion, and palpation. Auscultation allows the healthcare provider to listen for bowel sounds, followed by percussion to assess for areas of tenderness or abnormal distention, and finally palpation to feel for masses or organ enlargement. This sequence ensures a systematic and thorough assessment of the abdomen.
