1. After 5 days of diuretic therapy with 20mg of furosemide (Lasix) daily, a patient begins to exhibit fatigue, muscle cramping, and muscle weakness. These symptoms probably indicate that the patient is experiencing:
- A. Hypokalemia
- B. Hyperkalemia
- C. Anorexia
- D. Dysphagia
Correct answer: A
Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.
2. This heart condition is characterized by decreased cardiac output and tissue perfusion, which can lead to organ failure.
- A. Cardiogenic shock
- B. Myocardial infarction
- C. Endocarditis
- D. Pericarditis
Correct answer: A
Rationale: The correct answer is A: Cardiogenic shock. Cardiogenic shock is a severe condition characterized by the heart's inability to pump enough blood, leading to decreased cardiac output and tissue perfusion, which can result in organ failure. Choice B, Myocardial infarction, specifically refers to a blockage of blood flow to the heart muscle. Choices C and D, Endocarditis and Pericarditis, do not directly involve decreased cardiac output leading to organ failure, making them incorrect in the context of the symptoms described in the question.
3. An infant is born with a gastroschisis. Care preoperatively should include which priority intervention?
- A. Prone position
- B. Sterile water feedings
- C. Monitoring serum laboratory electrolytes
- D. Covering the defect with a sterile bowel bag
Correct answer: D
Rationale: The correct priority intervention for an infant with gastroschisis is to cover the exposed abdominal contents with a sterile bowel bag. This action helps protect the intestines from injury, contamination, and dehydration before surgical repair. Choice A, placing the infant in the prone position, is not appropriate as it does not address the immediate need to protect the exposed intestines. Choice B, sterile water feedings, and Choice C, monitoring serum laboratory electrolytes, are not the priority interventions for this condition. Sterile water feedings may not provide the necessary protection for the exposed intestines, and monitoring electrolytes, while important, is secondary to the immediate need for protection and hydration of the exposed abdominal contents.
4. The information-processing approach views the human mind as a __________.
- A. socially mediated process
- B. collection of stimuli and responses
- C. system of genetically programmed behaviors
- D. symbol-manipulating system through which information flows
Correct answer: D
Rationale: The information-processing approach views the human mind as a symbol-manipulating system through which information flows. This perspective emphasizes how information is received, processed, stored, and retrieved in the mind, similar to how a computer processes data through symbols and operations. Choices A, B, and C are incorrect because they do not align with the fundamental principles of the information-processing approach, which focuses on the mind's symbolic manipulation of information rather than being a socially mediated process, a collection of stimuli and responses, or a system of genetically programmed behaviors.
5. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?
- A. 6 mL/hr
- B. 8 mL/hr
- C. 12 mL/hr
- D. 16 mL/hr
Correct answer: A
Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.
