1. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

A. Assist-control
B. Synchronized intermittent mandatory ventilation
C. Continuous positive airway pressure
D. Pressure support ventilation

Correct answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

2. Which of the following is the correct abbreviation for drops?

A. Gtt.
B. Gtts.
C. Dp.
D. Dr.

Correct answer: A

Rationale: The correct abbreviation for drops in medical terminology is 'Gtt.' It is derived from the Latin word 'guttae,' meaning drops. The abbreviation 'Gtts.' (Choice B) is incorrect as it adds an unnecessary 's.' Choices C and D, 'Dp.' and 'Dr.,' are not standard abbreviations for drops in medical contexts, making them incorrect.

3. 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.

4. In which of the following organs does the exchange of gases take place?

A. Kidneys
B. Lungs
C. Liver
D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. A client is scheduled for a thoracentesis. Which of the following supplies should NOT be in the client's room?

A. Oxygen equipment
B. Incentive spirometer
C. Pulse oximeter
D. Sterile dressing

Correct answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.
