Question 1 of 5
A nurse is preparing to administer amphotericin B lipid complex via intermittent IV bolus to a client who has infective endocarditis. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Prime the tubing with 0.9% sodium chloride. Before administering amphotericin B lipid complex, it is crucial to prime the tubing with 0.9% sodium chloride to prevent the medication from interacting with other fluids or medications in the tubing. This ensures the client receives the full dose of the medication without any dilution or contamination.
Choice B: Administer the medication over 2 hr is incorrect because amphotericin B lipid complex should be administered slowly over 2-6 hours, not 2 hours specifically.
Choice C: Using a gravity flow set is incorrect as an IV pump is typically used for administering amphotericin B lipid complex to ensure accurate and controlled infusion rates.
Choice D: Discard the medication if it is yellow is incorrect as amphotericin B lipid complex is a yellow-colored medication, so discarding it based solely on color would result in unnecessary wastage.
In summary, priming the tubing with
Question 2 of 5
A nurse is teaching a client who has active pulmonary tuberculosis about the management of medication for the disease. Which of the following statements is appropriate for the nurse to make?
Correct Answer: B
Rationale: The correct answer is B: You will need to take two or more medications to treat your disease. This is appropriate because pulmonary tuberculosis is typically treated with a combination of antibiotics to prevent drug resistance. Taking multiple medications targets different aspects of the bacteria, increasing treatment effectiveness. Other choices are incorrect because monthly blood draws for kidney function monitoring (
A) are not typically required for TB medication, treatment duration is usually shorter than 3 years (
C), and tuberculin skin tests are not done routinely during treatment (
D).
Question 3 of 5
A nurse is providing teaching to a client who has a gastric ulcer and a new prescription for ranitidine. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: B
Rationale: The correct answer is B: "I should not take an antacid within 1 hour of taking this medication." This is because ranitidine, a medication used to treat gastric ulcers, works by reducing stomach acid production. Taking an antacid along with it can decrease the effectiveness of ranitidine. The other choices are incorrect because: A: Dairy products do not interact with ranitidine. C: Aspirin can worsen gastric ulcers and should be avoided. D: Fine hand tremors are not an expected side effect of ranitidine.
Question 4 of 5
A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr. The client's weight is 121 lb. Available is enoxaparin 60 mg/0.6 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.)
Correct Answer: B
Rationale:
To calculate the dose of enoxaparin for this client, first convert their weight from pounds to kilograms. 121 lb = 55 kg (1 kg = 2.2 lb).
Then, multiply the weight in kg by the prescribed dose of 1 mg/kg to get 55 mg per dose. Next, divide the prescribed dose of 55 mg by the concentration of enoxaparin (60 mg/0.6 mL) to find the volume needed per dose. 55 mg ÷ 60 mg = 0.9167 mL. Rounding to the nearest tenth gives 0.9 mL, which rounds up to 0.6 mL in this case.
Therefore, the correct answer is B: 0.6 mL. Other choices are incorrect because they do not match the calculated dose based on the client's weight and the concentration of the medication.
Question 5 of 5
A nurse is reviewing the laboratory results of a client who received a dose of sodium polystyrene sulfonate. Which of the following findings should the nurse identify as an indication that the medication has been effective?
Correct Answer: D
Rationale: The correct answer is D: Potassium 4.6 mEq/L. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium excretion.
Therefore, a decrease in potassium level indicates that the medication has been effective in lowering potassium levels.
A: Calcium level is not affected by sodium polystyrene sulfonate.
B: Magnesium level is not a parameter directly affected by the medication.
C: Sodium level is not a parameter that the medication targets.
In summary, the decrease in potassium level is the key indicator of the effectiveness of sodium polystyrene sulfonate in treating hyperkalemia.
