1. The healthcare provider prescribes oxytocin 2 milliunits/minute to induce labor for a client at 41-weeks gestation. The nurse initiates an infusion of Ringer’s Lactate solution 1000 mL with oxytocin 10 units. How many mL/hour should the nurse program the infusion pump?
- A. 12 mL/hour
- B. 2 mL/hour
- C. 22 mL/hour
- D. 42 mL/hour
Correct answer: A
Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) × total volume (1000 mL) ÷ units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.
2. The healthcare provider should recognize which of the following as an indication of dehydration in an elderly client?
- A. Skin turgor
- B. Dry mucous membranes
- C. Elevated temperature
- D. Increased pulse pressure
Correct answer: B
Rationale: Dry mucous membranes are a classic sign of dehydration, especially in elderly individuals. Dehydration can lead to decreased moisture in the mucous membranes, making them dry. Skin turgor, although commonly assessed for dehydration in younger individuals, may be less reliable in the elderly due to changes in skin elasticity. Elevated temperature is more indicative of an infection or other conditions. Increased pulse pressure is not typically associated with dehydration in the elderly.
3. The healthcare provider is caring for a client who is experiencing fluid volume deficit (dehydration). Which intervention should the healthcare provider implement to assess the effectiveness of fluid replacement therapy?
- A. Monitor daily weights
- B. Assess skin turgor
- C. Evaluate blood pressure trends
- D. Check urine specific gravity
Correct answer: A
Rationale: Monitoring daily weights is an accurate method to assess the effectiveness of fluid replacement therapy because changes in weight reflect changes in fluid balance. Fluid volume deficit can be objectively evaluated by monitoring daily weights as it provides a more precise measurement of fluid status over time. Assessing skin turgor (choice B) is subjective and may not provide as accurate or measurable data as monitoring daily weights. Evaluating blood pressure trends (choice C) can give information about circulatory status but may not directly reflect fluid volume status. Checking urine specific gravity (choice D) can indicate the concentration of urine but does not provide a comprehensive assessment of overall fluid balance like monitoring daily weights does.
4. The healthcare professional is assessing a client with a diagnosis of peripheral arterial disease (PAD). Which assessment finding is most indicative of this condition?
- A. Dependent rubor.
- B. Absence of hair on the lower legs.
- C. Shiny, thin skin on the legs.
- D. Pain in the legs when walking.
Correct answer: D
Rationale: Pain in the legs when walking (D), known as intermittent claudication, is most indicative of peripheral arterial disease (PAD). While dependent rubor (A), absence of hair (B), and shiny, thin skin (C) are also associated with PAD, they are less specific than intermittent claudication. Intermittent claudication is a hallmark symptom of PAD caused by inadequate blood flow to the legs during exercise, resulting in pain that resolves with rest.
5. What do prokaryotic cells lack in comparison to eukaryotic cells?
- A. A defined nucleus and a series of membrane-bound organelles
- B. A defined nucleus and no membrane-bound organelles
- C. No defined nucleus and a series of membrane-bound organelles
- D. No defined nucleus and no membrane-bound organelles
Correct answer: D
Rationale: Prokaryotic cells are characterized by the absence of a defined nucleus and membrane-bound organelles. Choice A is incorrect because prokaryotic cells lack membrane-bound organelles. Choice B is incorrect because prokaryotic cells lack both a defined nucleus and membrane-bound organelles. Choice C is incorrect as prokaryotic cells have no defined nucleus. Therefore, the correct answer is D.
