1. 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).
2. A charge nurse is recommending postpartum client discharge following a local disaster. Which of the following should the nurse recommend for discharge?
- A. A 42-year-old client who has preeclampsia and a BP of 166/110 mm Hg
- B. A 15-year-old client who delivered via emergency cesarean birth 1 day ago
- C. A client who received 2 units of packed RBCs 6 hr ago for a postpartum hemorrhage
- D. A client who delivered precipitously 36 hr ago and has a second-degree perineal laceration
Correct answer: D
Rationale: The most appropriate client to recommend for discharge following a local disaster in the postpartum unit is the one who delivered precipitously 36 hours ago and has a second-degree perineal laceration. This client's condition is stable enough for discharge, and the timing and extent of the perineal laceration are within expectations for a safe discharge. Clients with conditions such as preeclampsia, recent emergency cesarean birth, or recent administration of packed RBCs for postpartum hemorrhage require further monitoring and care before being considered for discharge.
3. How many drops are equivalent to 1 tsp?
- A. 15
- B. 60
- C. 10
- D. 30
Correct answer: B
Rationale: 1 teaspoon (tsp) is equivalent to approximately 60 drops. Drops and teaspoons vary in volume and size, affecting the conversion ratio. Choice A (15 drops) is incorrect as it's a common misconception. Choice C (10 drops) and Choice D (30 drops) do not align with the standard conversion of 1 tsp to 60 drops.
4. The client was asked to read the Snellen chart. Which of the following is being tested?
- A. Optic
- B. Olfactory
- C. Oculomotor
- D. Trochlear
Correct answer: A
Rationale: The correct answer is A: Optic. The Snellen chart is used to test visual acuity, which assesses the function of the optic nerve responsible for vision. Choices B, C, and D are incorrect. Olfactory relates to the sense of smell, oculomotor controls eye movement, and trochlear controls certain eye muscles. Therefore, the only option related to vision testing in this context is the optic nerve.
5. 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.
