1. Which of the following blood tests should be performed before a blood transfusion?
- A. Prothrombin and coagulation time
- B. Blood typing and cross-matching
- C. Bleeding and clotting time
- D. Complete blood count (CBC) and electrolyte levels
Correct answer: B
Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.
2. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:
- A. Infection
- B. Hypothermia
- C. Anxiety
- D. Dehydration
Correct answer: D
Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
3. A client has a new prescription for heparin therapy. Which of the following statements by the client should indicate an immediate concern for the nurse?
- A. ''I am allergic to morphine.''
- B. ''I take antacids several times a day.''
- C. ''I had a blood clot in my leg several years ago.''
- D. ''It hurts to take a deep breath.''
Correct answer: ''I take antacids several times a day.''
Rationale: The correct answer is the statement 'I take antacids several times a day.' Antacids can alter the absorption of heparin, potentially affecting its effectiveness and increasing the risk of clot formation. This is a significant concern as it can impact the therapeutic outcome of heparin therapy. The other statements are not directly related to potential complications or interactions with heparin therapy.
4. 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.
5. How many liters are equal to 1800 ml?
- A. 1.8
- B. 18000
- C. 180
- D. 2800
Correct answer: A
Rationale: To convert milliliters (ml) to liters, divide by 1000 since 1 liter is equal to 1000 ml. Therefore, 1800 ml is equal to 1800/1000 = 1.8 liters. Choice A (1.8) is correct. Choice B (18000) is incorrect as it equates to 18000 liters, not 1.8 liters. Choice C (180) is incorrect as it represents 180 liters, not 1.8 liters. Choice D (2800) is incorrect as it does not reflect the conversion of 1800 ml to liters.
