1. What special consideration should be taken into account when Mario prepares Richard for postural drainage and percussion?
- A. Monitoring a respiratory rate of 16 to 20 per minute
- B. Assessing the client's ability to tolerate sitting and lying positions
- C. Ensuring the client is free of signs of infection
- D. Knowing the time of the client's last food and fluid intake
Correct answer: A
Rationale: The correct answer is A, 'Monitoring a respiratory rate of 16 to 20 per minute'. When performing postural drainage and percussion, it is crucial to monitor the respiratory rate to ensure the safety and effectiveness of the procedure. Choice B, 'Assessing the client's ability to tolerate sitting and lying positions', while important, is not directly related to the specifics of postural drainage and percussion. Similarly, option C, 'Ensuring the client is free of signs of infection', although important, is not directly linked to the procedure. Option D, 'Knowing the time of the client's last food and fluid intake', might be relevant for other procedures, but it is not the primary consideration for postural drainage and percussion.
2. A nurse is preparing to administer an intermittent enteral feeding to a client who has a gastrostomy tube. Which of the following actions should the nurse take?
- A. Flush the tube with 30 mL of water after feeding
- B. Flush the tube with 10 mL of sterile water before feeding
- C. Place the client in a left lateral position
- D. Place the feeding bag 61 cm (24 in) above the client's abdomen
Correct answer: B
Rationale: Administering an intermittent enteral feeding through a gastrostomy tube requires flushing the tube with 10 mL of sterile water before feeding. This action helps ensure patency and prevents clogging. Choice A is incorrect because flushing after feeding does not address the need for pre-feeding tube flushing. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height of the feeding bag above the abdomen is typically regulated by healthcare facility policies and is not a universal standard.
3. Which two dietary components may help decrease blood cholesterol levels?
- A. Omega-3 fatty acids and soluble fiber
- B. Short-chain fatty acids and insoluble fiber
- C. Trans fatty acids and potassium
- D. Cis fatty acids and calcium
Correct answer: A
Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.
4. Which of the following statements should a healthcare provider recognize as true about defense mechanisms? Select all that apply.
- A. They are employed when there is a threat to biological or psychological integrity.
- B. They are controlled by the id and deal with primal urges.
- C. They are used in an effort to increase anxiety.
- D. They are protective devices for the superego.
Correct answer: A
Rationale: Defense mechanisms are employed by the ego, not the id or superego, in response to threats to biological or psychological integrity. They aim to relieve anxiety, not increase it. By redirecting focus, they help manage mild to moderate anxiety and are often self-deceptive in nature.
5. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?
- A. Position the client in a side-lying position.
- B. Perform the irrigation using a 20-mL syringe.
- C. Instill 15 mL of irrigation fluid into the catheter with each flush.
- D. Measure and record the amount of irrigant used.
Correct answer: B
Rationale: When irrigating an indwelling urinary catheter, the nurse should use a 20-mL syringe for the procedure. This syringe size helps to provide adequate pressure for effective irrigation. Placing the client in a side-lying position is not necessary for this procedure. Instilling a specific amount of irrigation fluid into the catheter is not mentioned in the scenario. Subtracting the amount of irrigant used from the client's urine output is not a standard practice in catheter irrigation.
