A nurse is caring for a client who is receiving morphine through a PCA device. Which of the following actions should the nurse take?
- A. Teach the client how to self-medicate using the PCA device.
- B. Encourage family members to press the PCA button for the client.
- C. Monitor the client's respiratory status every 4 hr.
- D. Administer an oral opioid for breakthrough pain.
Correct Answer: A
Rationale: The correct answer is A. Teaching the client how to self-medicate using the PCA device is essential to empower the client in managing their pain effectively. This promotes autonomy and ensures the client receives the appropriate dose at the right time, enhancing pain control. Choice B is incorrect as family members should not press the PCA button for the client to maintain safety and prevent medication errors. Choice C is incorrect as respiratory status should be monitored more frequently, ideally every 1-2 hours, when a client is receiving opioids due to the risk of respiratory depression. Choice D is incorrect as administering an oral opioid for breakthrough pain may lead to overdose or adverse effects when already receiving morphine through PCA.

A nurse is caring for a client who has chronic venous insufficiency. Which of the following areas should the nurse assess for the presence of a venous ulcer?
- A. Tip of the toes
- B. Medial malleolus (ankle)
- C. Ball of the foot
- D. Heel of the foot
Correct Answer: B
Rationale: The correct answer is B: Medial malleolus (ankle). Venous ulcers commonly occur in the lower legs, particularly around the medial malleolus due to poor circulation in chronic venous insufficiency. The pressure and pooling of blood in the veins can lead to tissue breakdown and ulcer formation in this area. Assessing the medial malleolus for the presence of a venous ulcer is crucial in managing the client's condition.
Incorrect Choices:
A: Tip of the toes - Venous ulcers are less likely to occur in this area as it is more distal and less affected by venous insufficiency.
C: Ball of the foot - Venous ulcers are more commonly found in the lower legs rather than the ball of the foot.
D: Heel of the foot - While ulcers can develop on the heel, they are less likely to be venous ulcers in chronic venous insufficiency compared to the medial malleol
A nurse is analyzing the ABG results of a client who is in respiratory acidosis. Which of the following mechanisms should the nurse identify as responsible for this acid-base imbalance?
- A. Retention of carbon dioxide
- B. Loss of bicarbonate
- C. Excessive vomiting
- D. Hyperventilation
Correct Answer: A
Rationale: The correct answer is A: Retention of carbon dioxide. In respiratory acidosis, there is an excess of carbon dioxide (CO2) in the blood, leading to a decrease in pH. This imbalance occurs when the lungs are unable to eliminate enough CO2 through respiration, causing it to accumulate in the bloodstream. This excess CO2 combines with water in the blood to form carbonic acid, leading to acidosis. Choices B, C, and D are incorrect as they do not directly relate to the accumulation of CO2 in respiratory acidosis. Loss of bicarbonate (B) would lead to metabolic acidosis, excessive vomiting (C) would cause metabolic alkalosis, and hyperventilation (D) would actually help in decreasing CO2 levels, which is not the case in respiratory acidosis.
A nurse is completing discharge teaching with a client who has a new diagnosis of AIDS. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will increase the amount of fresh fruits and vegetables I consume.'
- B. I will need to take my clothes to the dry cleaners to sterilize them.'
- C. I will be sure to wear gloves and wash my hands when I change my cat's litter box.'
- D. I will wipe up areas soiled with body fluids with alcohol and immediately dispose of the trash.'
Correct Answer: D
Rationale: Correct Answer: D
Rationale:
1. Using alcohol to wipe up areas soiled with body fluids helps to disinfect the surfaces, reducing the risk of infection spread.
2. Immediately disposing of the trash containing body fluids prevents further exposure to infectious materials.
3. This statement demonstrates understanding of infection control measures crucial for someone with AIDS.
Incorrect Choices:
A: Increasing fresh fruits and vegetables is a healthy choice but not directly related to preventing infection spread in the context of AIDS.
B: Taking clothes to the dry cleaners for sterilization is unnecessary and does not address infection control.
C: Wearing gloves and washing hands when changing a cat's litter box is a good hygiene practice but not specific to preventing transmission of HIV.
A nurse is caring for a client who has oral achalasia, The nurse should ask the client which of the following questions to assess their ability to swallow?
- A. Do you feel like you have food stuck at the base of your throat?'
- B. Do you have any feelings of fullness in the neck?'
- C. Do you feel any burning sensations in your throat?'
- D. Do you have any problems with pain while swallowing?'
Correct Answer: A
Rationale: The correct answer is A: "Do you feel like you have food stuck at the base of your throat?" This question is appropriate for assessing the client's ability to swallow because oral achalasia is a condition where the lower esophageal sphincter fails to relax, causing difficulty in passing food from the mouth to the esophagus. Asking about the sensation of food stuck in the throat helps to identify this symptom.
Choice B: "Do you have any feelings of fullness in the neck?" is incorrect because fullness in the neck is not a typical symptom of oral achalasia.
Choice C: "Do you feel any burning sensations in your throat?" is incorrect because burning sensations are more commonly associated with acid reflux or GERD, not specifically with oral achalasia.
Choice D: "Do you have any problems with pain while swallowing?" is incorrect as pain while swallowing is not a typical symptom of oral achalasia.
Therefore, the correct question to assess
A nurse is providing teaching for a client who has diabetes mellitus about the self-administration of insulin.The client has prescriptions for regular and NPH insulins. Which
of the following statements by the client indicates an understanding of the teaching?
- A. I will draw up the regular insulin into the syringe first.
- B. I will shake the NPH vial vigorously before drawing up the insulin.
- C. I will store prefilled syringes in the refrigerator with the needle pointed downward.
- D. I will insert the needle at a 15-degree angle.
Correct Answer: A
Rationale: Correct Answer: A: I will draw up the regular insulin into the syringe first.
Rationale: Drawing up regular insulin first is crucial for preventing contamination between the two insulins. Regular insulin is a clear solution and should be drawn up first to prevent any cloudiness or contamination from the NPH insulin, which is a cloudy suspension. Drawing up regular insulin first ensures accuracy in dosing and prevents mixing of the two insulins.
Incorrect Choices:
B: Shaking the NPH vial vigorously before drawing up the insulin is incorrect as it can cause bubbles and affect the accuracy of the dose.
C: Storing prefilled syringes in the refrigerator with the needle pointed downward is incorrect as it can lead to leakage or contamination.
D: Inserting the needle at a 15-degree angle is incorrect as insulin injections should be administered at a 90-degree angle for proper absorption.
