1. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

2. 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.

3. What term refers to the manner of walking?

• A. Gait
• B. Range of motion
• C. Flexion and extension
• D. Hopping

Correct answer: A

Rationale: Gait specifically refers to the manner in which a person walks. It encompasses the pattern, rhythm, and style of walking, making it the most appropriate term in this context. Choices B, C, and D are incorrect. Range of motion refers to the extent of movement of a joint, flexion and extension relate to bending and straightening movements at a joint, and hopping is a specific type of movement that involves jumping on one foot.

4. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

5. A healthcare provider is caring for a client following a thoracentesis. Which of the following manifestations should the healthcare provider NOT recognize as risks for complications?

• A. Dyspnea
• B. Localized bloody drainage on the dressing
• C. Fever
• D. Hypotension

Correct answer: B

Rationale: After a thoracentesis, some expected complications include dyspnea, fever, and hypotension. Localized bloody drainage on the dressing is a common and expected finding post-thoracentesis due to the procedure's nature of puncturing the chest wall. Therefore, the healthcare provider should not consider this finding as a risk for complications.
