When caring for a client on pressure support ventilation (PSV), which statement by the nurse indicates an understanding of PSV?
- A. It keeps the alveoli open and prevents atelectasis.
- B. It allows preset pressure delivered during spontaneous ventilation.
- C. It guarantees minimal minute ventilator.
- D. It delivers a preset ventilatory rate and tidal volume to the client.
Correct Answer: B
Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.

A group of clients are being educated about influenza. Which of the following client statements indicates an understanding of the teaching?
- A. ''I should wash my hands after blowing my nose to prevent spreading the virus.''
- B. ''I need to avoid drinking fluids if I develop symptoms.''
- C. ''I need a flu shot every 2 years because of the different flu strains.''
- D. ''I should cover my mouth with my hand when I sneeze.''
Correct Answer: A
Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.
During an assessment, a healthcare provider observes a client with a chest tube and drainage system. What is an expected finding?
- A. Continuous bubbling in the water seal chamber
- B. Gentle constant bubbling in the suction control chamber
- C. Drainage system positioned upright at chest level
- D. Exposed sutures without dressing
Correct Answer: B
Rationale: When assessing a client with a chest tube and drainage system, gentle constant bubbling in the suction control chamber is an expected finding. This indicates that the system is functioning properly. Continuous bubbling in the water seal chamber would suggest an air leak, the drainage system should be positioned upright at chest level to promote proper drainage, and exposed sutures without dressing would be an incorrect finding as they should be covered to prevent infection.
When assessing a client with a history of asthma, which of the following factors should the nurse identify as a risk for asthma?
- A. Gender
- B. Environmental allergies
- C. Alcohol
- D. None of the above
Correct Answer: B
Rationale: When assessing a client with a history of asthma, the nurse should identify environmental allergies as a risk factor for asthma. Environmental allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms and exacerbate the condition. Gender, alcohol consumption, and other factors may not directly contribute to the development or exacerbation of asthma.
A client has global aphasia affecting both receptive and expressive language abilities. Which intervention should NOT be included in the client's care plan?
- A. Speak to the client at a slower rate.
- B. Assist the client in using flash cards with pictures.
- C. Speak to the client in a loud voice.
- D. Give instructions one step at a time.
Correct Answer: C
Rationale: Individuals with global aphasia have difficulty understanding and expressing language. Speaking loudly may not improve comprehension and can be perceived as aggressive. Therefore, it is important not to speak loudly to a client with global aphasia. Speaking at a slower rate, using visual aids like flash cards, and breaking down instructions into simple steps can facilitate communication and understanding for the client.
A client experiencing dyspnea will receive continuous oxygen. Which oxygen device should be used to deliver a precise amount of oxygen?
- A. Non-rebreather mask
- B. Venturi mask
- C. Nasal cannula
- D. Simple face mask
Correct Answer: B
Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.
