1. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 0.5 mL
- B. 1 mL
- C. 1.5 mL
- D. 2 mL
Correct answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg รท 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
2. The client has been diagnosed with deep vein thrombosis (DVT). Which symptom would be most concerning?
- A. Pain in the affected leg
- B. Redness and warmth in the affected leg
- C. Shortness of breath
- D. Swelling in the affected leg
Correct answer: C
Rationale: Shortness of breath is the most concerning symptom in a client with deep vein thrombosis (DVT) because it could indicate a pulmonary embolism, a life-threatening complication where a blood clot travels to the lungs. This condition requires immediate medical attention. While pain, redness, warmth, and swelling in the affected leg are common symptoms of DVT, shortness of breath suggests a more critical situation that necessitates urgent intervention.
3. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Monitor serum calcium levels.
- B. Monitor serum potassium levels.
- C. Monitor serum sodium levels.
- D. Monitor serum magnesium levels.
Correct answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
4. A nurse on a medical-surgical unit is caring for a client. Which of the following actions should the nurse take first when using the nursing process?
- A. Obtain client information
- B. Develop a plan of care
- C. Implement nursing interventions
- D. Evaluate the client's response to treatment
Correct answer: A
Rationale: The correct answer is A: Obtain client information. The first step in the nursing process is assessment, which involves gathering data about the client's condition, needs, and preferences. This information forms the foundation for developing a comprehensive plan of care. Developing a plan of care (Choice B) comes after assessment to address the identified needs. Implementing nursing interventions (Choice C) follows the development of the plan of care. Evaluating the client's response to treatment (Choice D) occurs after implementing the interventions to determine the effectiveness of the care provided. Therefore, the initial and priority step is to obtain client information through assessment.
5. A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the LPN/LVN monitor to determine the effectiveness of this medication?
- A. Serum potassium
- B. Hemoglobin
- C. Serum creatinine
- D. Blood urea nitrogen (BUN)
Correct answer: B
Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.
