Nokea
The nurse notes in the patient™s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder?
- A. Ventricular ectopy
- B. Atrial fibrillation
- C. Supraventricular tachycardia
- D. Bradycardia
Correct Answer: B
Rationale: Ibutilide (Corvert) is a class III antiarrhythmic medication primarily used for the treatment of atrial fibrillation and atrial flutter. It works by prolonging the action potential duration and refractory period of atrial tissue. Therefore, when a nurse notes that a patient will be taking ibutilide, it indicates that the patient likely has atrial fibrillation, a common arrhythmia characterized by rapid, irregular electrical activity in the atria of the heart.

A solution for the eyes
- A. effervescent
- B. mucilage
- C. spirits
- D. collyria
Correct Answer: D
Rationale: Collyria refers to eye drops or an eye lotion that is used to treat eye conditions. When the question is asking for a solution for the eyes, collyria is the most appropriate choice among the options given. Effervescent, mucilage, and spirits do not specifically relate to eye treatments. Collodion is a type of liquid adhesive used in medical settings, but it is not primarily intended for eye-related issues. Therefore, collyria is the correct solution for the eyes.
To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct Answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
When teaching a client who has a new prescription for Ciprofloxacin, which of the following instructions should the nurse include?
- A. Take this medication with an antacid.
- B. Avoid direct sunlight.
- C. Increase your intake of dairy products.
- D. Expect urine to turn orange.
Correct Answer: B
Rationale: The correct instruction for a client prescribed Ciprofloxacin is to avoid direct sunlight. Ciprofloxacin can cause photosensitivity, increasing the risk of sunburn. Clients should be advised to avoid direct sunlight and wear protective clothing, including hats and sunglasses when going outdoors to prevent skin damage. Choices A, C, and D are incorrect. Taking Ciprofloxacin with an antacid can reduce its absorption, so they should not be taken together. Increasing dairy product intake is not necessary or relevant to taking Ciprofloxacin. While Ciprofloxacin can discolor urine, turning it orange, this is not a critical side effect that requires specific instructions for the client.
A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct Answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
A client is starting a new prescription for enalapril. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Rise slowly from a sitting position.
- C. Avoid salt substitutes.
- D. Avoid exposure to sunlight.
Correct Answer: C
Rationale: The correct instruction for a client starting enalapril is to avoid salt substitutes. Salt substitutes may contain potassium, which could lead to elevated potassium levels when combined with enalapril, increasing the risk of hyperkalemia. Choices A, B, and D are incorrect because there is no specific need to take enalapril with food, rise slowly from a sitting position, or avoid exposure to sunlight when taking this medication.
