1. A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct answer: A
Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.
2. A nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr? (Round the answer to the nearest whole number)
- A. 63 mL/hr
- B. 36 mL/hr
- C. 78 mL/hr
- D. 90 mL/hr
Correct answer: A
Rationale: To calculate the rate for the enteral tube feeding, divide the total volume by the total time: 250 mL / 4 hr = 62.5 ≈ 63 mL/hr. Therefore, the nurse should set the pump to deliver 63 mL/hr. Choices B, C, and D are incorrect as they do not match the correct calculation result. B is too low, C is too high, and D is also too high based on the correct calculation.
3. A client with a seizure disorder has a new prescription for valproic acid. Which of the following laboratory values should the nurse plan to monitor? (Select all that apply)
- A. PTT
- B. Aspartate aminotransferase (AST)
- C. Alanine aminotransferase (ALT)
- D. All of the Above
Correct answer: D
Rationale: The correct answer is D, 'All of the Above.' Valproic acid can impact liver function and coagulation. Monitoring the Prothrombin Time (PTT), Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) is crucial. PTT is monitored to assess coagulation status, while AST and ALT are liver enzymes that indicate liver function. Monitoring these values helps detect any potential adverse effects of valproic acid on the liver and blood clotting. Choices A, B, and C are incorrect because each of these laboratory values plays a critical role in evaluating the client's response to valproic acid therapy and detecting associated complications.
4. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
5. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)
- A. 2.6 mL
- B. 2.63 mL
- C. 2.7 mL
- D. 2.2 mL
Correct answer: A
Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb ÷ 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg × 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg ÷ 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.
