Question 1 of 5
A nurse is preparing to administer atenolol 25 mg PO every 12 hr. The amount available is atenolol 50 mg/tab. How many tablets should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 0.5 tablets.
To administer 25 mg every 12 hours, the nurse needs to give half of a 50 mg tablet (50 mg ÷ 2 = 25 mg). This is because the available tablets are 50 mg each, so half of a tablet will provide the required dose of 25 mg.
Choices B, C, and D are incorrect as they do not consider the need to halve the tablet to achieve the correct dose of 25 mg.
Question 2 of 5
A nurse is preparing to administer enoxaparin to a client. Which of the following actions should the nurse plan to take?
Correct Answer: B
Rationale: The correct answer is B. When administering enoxaparin, the nurse should not expel the air bubble in the prefilled syringe. This is because the air bubble is necessary to ensure that the full dose of medication is administered. Expelling the air bubble may lead to underdosing the client.
Choice A is incorrect because enoxaparin should be administered subcutaneously at a 90° angle.
Choice C is incorrect as the medication should be administered in the abdomen, not specifically 2.54 cm from the umbilicus.
Choice D is incorrect because there is no need to aspirate for a blood return before administering enoxaparin subcutaneously.
Question 3 of 5
A nurse is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets should the nurse administer?
Correct Answer: B
Rationale: The correct answer is B: 2 tablets.
To achieve a total of 0.25 mg of digoxin daily, the nurse should administer 2 tablets of 0.125 mg each, totaling 0.25 mg. This is calculated by dividing the desired dose (0.25 mg) by the dose per tablet (0.125 mg) which equals 2 tablets.
Choices A, C, and D are incorrect because they do not achieve the desired dose of 0.25 mg.
Question 4 of 5
A nurse is assessing a client who is taking lisinopril to treat hypertension. Which of the following findings is a priority to report?
Correct Answer: C
Rationale: The correct answer is C: Swelling of the tongue. This finding is a priority to report because it could indicate a severe allergic reaction known as angioedema, which can compromise the client's airway and lead to anaphylaxis. It is crucial to address this immediately to prevent respiratory distress.
Choice A, Nausea, is a common side effect of lisinopril but is not as urgent as potential angioedema.
Choice B, Dry cough, is a common side effect of ACE inhibitors like lisinopril but is not immediately life-threatening.
Choice D, Nasal congestion, is a less serious side effect compared to angioedema.
Question 5 of 5
A nurse is teaching a client who has a new prescription for simvastatin. Which of the following instructions should the nurse include?
Correct Answer: D
Rationale: The correct answer is D: You should avoid grapefruit juice. Grapefruit juice can interact with simvastatin, leading to increased levels of the medication in the blood, which can increase the risk of side effects.
Therefore, it is essential to avoid grapefruit juice while taking simvastatin to ensure the medication works effectively and safely.
Choice A is incorrect because brown-colored urine is not a common side effect of simvastatin.
Choice B is incorrect as there is no specific requirement to take simvastatin in the morning.
Choice C is incorrect as ringing in the ears is not a common side effect of simvastatin.
