Question 1 of 5
A nurse is caring for a client who has sickle cell anemia. The client asks,Why do I feel so tired and fatigued all of the time? Which of the following information should the nurse provide?
Correct Answer: B
Rationale:
Correct
Answer: B - You have fewer red blood cells.
Rationale: In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky, and crescent-shaped, leading to decreased oxygen delivery. This results in anemia, leading to fatigue and tiredness.
Choice A is incorrect as it does not directly relate to the pathophysiology of sickle cell anemia.
Choice C is unrelated to the client's symptoms.
Choice D is not specific to the underlying cause of fatigue in sickle cell anemia.
Question 2 of 5
Administer Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Do not round your answer and include unit of measure with each answer)
Correct Answer: 7.2
Rationale:
To calculate the correct answer, first convert the client's weight from pounds to kilograms (176 lb / 2.2 = 80 kg).
Then, calculate the total dose per minute (3 mcg/kg/min * 80 kg = 240 mcg/min). Next, calculate the total dose per hour (240 mcg/min * 60 min = 14,400 mcg/hr). Finally, determine the mL/hr by dividing the total dose per hour by the concentration of the drug (14,400 mcg/hr / 500 mg in 250 mL = 28.8 mL/hr).
Therefore, the correct answer is 240 mcg/min, 14,400 mcg/hr, and 28.8 mL/hr. Other choices are incorrect as they do not follow the proper conversion and calculation steps.
Question 3 of 5
The physician orders a Lidocaine drip to infuse at 2 mg/min. The drug is available as 2 gm in 500 mL of fluid. Solve for mL/hr.
Correct Answer: 3
Rationale:
To solve for mL/hr, we first need to convert 2 gm to mg (2000 mg) and calculate the total volume in mL (500 mL).
Then, we divide the total volume by the rate of infusion (2 mg/min) to get mL/min (250 mL/min). Finally, multiply this by 60 to get mL/hr (15000 mL/hr).
Choice 3 is correct because it correctly follows these steps. Other choices are incorrect due to miscalculations or skipping a step.
Question 4 of 5
A nurse is interviewing a school-age child who has intermittent explosive disorder (IED). Which of the following behaviors should the nurse expect the client to exhibit?
Correct Answer: A
Rationale: The correct answer is A: Lack of remorse for behavior. In intermittent explosive disorder (IE
D), individuals exhibit sudden and intense episodes of aggression or violence. They may act impulsively without considering consequences or feeling remorse afterward. This lack of remorse is a key characteristic of IED, distinguishing it from other behavioral disorders like conduct disorder where remorse might be present.
Choices B, C, and D are incorrect because mild outbursts with provocation, blaming others for behavior, and difficulty coping with stressors are not specific to IED but can be seen in various other behavioral disorders or stress-related conditions.
Question 5 of 5
The nurse in the emergency room is reviewing the health record of a client who is being evaluated for Graves' disease. Which of the following laboratory results is an expected finding?
Correct Answer: D
Rationale: The correct answer is D: Decreased thyroid-stimulating hormone (TSH). In Graves' disease, there is excessive production of thyroid hormones, leading to negative feedback on the pituitary gland, resulting in decreased TSH levels. This is because the elevated thyroid hormone levels signal the pituitary gland to decrease TSH production.
A: Decreased thyrotropin receptor antibodies - This is incorrect as Graves' disease is associated with increased levels of these antibodies.
B: Decreased free thyroxine index - This is incorrect as Graves' disease typically presents with elevated levels of free thyroxine.
C: Decreased triiodothyronine - This is incorrect as Graves' disease is characterized by elevated levels of triiodothyronine due to increased thyroid hormone production.
In summary, the expected finding in Graves' disease is a decreased TSH level due to the negative feedback mechanism, making option D the correct choice.
