Question 1 of 5

A nurse is giving a patient a loading dose of 1 mg of an antiarrhythmic drug to treat atrial flutters. Which of the following is most likely the drug being administered?

Correct Answer: A

Rationale: Digoxin is commonly used to treat atrial flutter and atrial fibrillation by helping to control the heart rate. A loading dose may be given initially to reach therapeutic levels quickly. This medication acts by increasing the force of the heart's contractions and slowing down the heart rate. Propranolol (Choice B) is a beta-blocker used to treat various heart conditions, but it is not typically used for atrial arrhythmias like atrial flutter. Ibuprofen (Choice C) is a nonsteroidal anti-inflammatory drug used for pain and inflammation, not for cardiac arrhythmias. Lithium (Choice D) is a mood-stabilizing medication often used for bipolar disorder and is not indicated for atrial flutter treatment.

Question 2 of 5

Which of the following refers to the metabolism of the drug en route from the GUT lumen to the systemic circulation.

Correct Answer: B

Rationale: The first pass effect refers to the metabolism of a drug occurring as it passes from the gastrointestinal tract (GUT lumen) to the liver, before reaching the systemic circulation. This process can significantly reduce the amount of active drug that enters systemic circulation, impacting the drug's overall effectiveness. The first pass effect is an important consideration in pharmacokinetics as it affects the bioavailability of a drug and influences dosing regimens. Options A, C, D, and E do not specifically pertain to the metabolism of a drug en route from the GUT lumen to the systemic circulation as described in the question.

Question 3 of 5

A patient is receiving tetracycline. Which advice should the nurse include when teaching this patient about tetracycline?

Correct Answer: A

Rationale: Tetracycline can cause photosensitivity, increasing the risk of severe sunburn. Patients should be advised to use sunscreen and avoid prolonged sun exposure. Taking antacids with tetracycline is contraindicated, as they can bind to the drug and reduce its absorption. Hearing loss and retinal damage are not associated with tetracycline use. Instead, patients should be monitored for gastrointestinal side effects and advised to take the medication with food if tolerated.

Question 4 of 5

The nurse assesses the patient receiving phentolamine (Regitine) and suspects what finding is an adverse effect of the medication?

Correct Answer: C

Rationale: Patients receiving phentolamine often experience extensions of the therapeutic effects, including hypotension, orthostatic hypotension, angina, myocardial infarction, cerebrovascular accident, flushing, tachycardia, and arrhythmia all of which are related to vasodilation and decreased blood pressure. Headache, weakness, and dizziness often occur in response to hypotension. Nausea, vomiting, and diarrhea may also occur. Hypertension, wheezing, and depressed respiration would not be associated with phentolamine. The nurse should monitor for adverse effects and intervene as needed.

Question 5 of 5

The nurse will be administering an antitussive medication containing codeine to a patient. What is the priority assessment?

Correct Answer: C

Rationale: Codeine, an opioid antitussive, can cause respiratory depression as a side effect. The nurse must assess the patient’s respiratory rate before administration to ensure it is within a safe range (typically >12 breaths per minute). While lung sounds (B) and sputum consistency (D) are important, they are not the priority when administering a medication that can suppress respiration. Pulse oximetry (A) is useful but secondary to direct respiratory rate assessment.
