Question 1 of 5
A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth.)
Correct Answer: 7.5
Rationale: The correct answer is 7.5 mL.
To determine this, first calculate the total daily dose: 20 mEq/day ÷ 2 doses/day = 10 mEq/dose. Next, find the mL per dose using the available concentration: 10 mEq ÷ 6.7 mEq/5 mL = 7.46 mL, which rounds to 7.5 mL. This ensures the patient receives the correct dose of potassium chloride elixir. Other choices are incorrect because they do not follow the correct calculation or rounding process, leading to potential under or overdosing.
Question 2 of 5
A nurse is instructing a client who has a new prescription for a daily dose of lovastatin extended-release. Which of the following information should the nurse include in the teaching?
Correct Answer: A
Rationale: The correct answer is A: You will need liver function tests before beginning therapy. This is important because lovastatin, a statin medication, can potentially cause liver damage. Liver function tests are necessary to monitor for any signs of liver toxicity.
Choice B is incorrect because there is no specific interaction between lovastatin and dairy products.
Choice C is incorrect as lovastatin extended-release should not be crushed as it may affect its effectiveness.
Choice D is incorrect as there is no specific time of the day required to take lovastatin.
Question 3 of 5
A nurse is assessing a client who is receiving a peripheral IV infusion and notes infiltration of fluid into the tissue surrounding the insertion site. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct action is to elevate the extremity. Elevating the extremity above the level of the heart helps to reduce swelling and prevent further fluid infiltration into the surrounding tissue. This promotes proper circulation and limits potential complications. Flushing the IV catheter (choice
A) would not address the infiltration issue. Applying pressure to the IV site (choice
B) could cause further damage to the tissue. Slowing the infusion rate (choice
D) may not be sufficient to prevent further infiltration.
Question 4 of 5
A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer? (Round to the nearest tenth.)
Correct Answer: 0.4
Rationale:
To calculate the mL of heparin to administer, use the formula: desired dose (4,000 units) ÷ concentration (10,000 units/mL) = X mL. 4,000 ÷ 10,000 = 0.4 mL. The correct answer is 0.4 mL because it accurately represents the calculated dose needed for the client. Other choices are incorrect as they do not align with the correct calculation.
Question 5 of 5
A nurse is caring for a client who is in shock and is receiving an infusion of albumin. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: The correct answer is C: Increase in BP. Albumin is a colloid solution that helps increase blood volume and subsequently improves blood pressure in shock patients. Increasing blood volume leads to an increase in blood pressure. Option A is incorrect because oxygen saturation is not directly affected by albumin infusion. Option B is incorrect because a low PaCO2 level is not a direct effect of albumin infusion. Option D is incorrect because albumin is a protein and its infusion would not lead to a decrease in protein levels.
