The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?

Correct Answer: A

Rationale: Consuming high amounts of foods rich in potassium, such as leafy green vegetables, can potentially decrease the effectiveness of digoxin. Digoxin works by helping the heart beat more strongly and regularly, but too much potassium in the body can interfere with its action. Therefore, patients taking digoxin are usually advised to avoid consuming excessive amounts of foods high in potassium, such as leafy green vegetables. It is recommended for patients on digoxin therapy to maintain a consistent level of potassium in their diet and follow their healthcare provider's guidance on dietary restrictions.

Correct Answer: B

Rationale: It is important to educate the patient to take levothyroxine at the same time every day, preferably in the morning on an empty stomach. Consistency in timing helps to maintain stable levels of the medication in the body and optimize its effectiveness in balancing thyroid activity. This medication should not be taken with food, vitamins, or other medications that can interfere with its absorption. Regular thyroid tests are necessary to monitor the effectiveness of the medication and adjust the dosage as needed. If a patient has experienced a recent myocardial infarction or heart attack, it is crucial to consult with healthcare professionals before starting or continuing levothyroxine, as it can have implications on cardiovascular health. It is never advisable for patients to avoid consulting their healthcare professionals if they experience any adverse effects or have concerns about their medication.

Correct Answer: A

Rationale: A. Assess lung sounds, Pulse, and Blood pressure before administering: Before administering Albuterol, it is crucial to assess the patient's lung sounds, pulse, and blood pressure as baseline data. This helps in monitoring the effects of Albuterol on the respiratory and cardiovascular systems.

Correct Answer: A

Rationale: It is recommended for the patient to take Digoxin in the morning when awakening. This is because Digoxin has a long half-life which means it stays in the body for a long period of time. By taking it in the morning, the patient can benefit from its effects throughout the day, including its ability to slow down the heart rate and improve heart function. Additionally, taking it in the morning helps to reduce the risk of potential interactions with other medications or food consumed later in the day.

Correct Answer: A

Rationale: Consuming high amounts of foods rich in potassium, such as leafy green vegetables, can potentially decrease the effectiveness of digoxin. Digoxin works by helping the heart beat more strongly and regularly, but too much potassium in the body can interfere with its action. Therefore, patients taking digoxin are usually advised to avoid consuming excessive amounts of foods high in potassium, such as leafy green vegetables. It is recommended for patients on digoxin therapy to maintain a consistent level of potassium in their diet and follow their healthcare provider's guidance on dietary restrictions.

Correct Answer: B

Rationale: Pharmacokinetics is the study of how drugs are absorbed, distributed, metabolized, and excreted by the body. These processes determine the concentration of a drug at its site of action and contribute to understanding the drug's effectiveness and potential side effects. Therefore, absorption, distribution, metabolism, and excretion are key components of pharmacokinetics. Pharmacodynamics (Choice A) refers to the study of the physiological effects of drugs and their mechanisms of action, which is different from the processes involved in drug movement through the body. Therapeutic action (Choice C) refers to the desired effects of a drug in treating a specific condition, rather than the processes involved in drug processing in the body. Pharmaceutical preparation (Choice D) is related to the formulation and development of drugs before their administration, not to the processes within the body. Toxic effect (Choice E) refers to the harmful effects of drugs, which can result from various factors including pharmacokin

Correct Answer: A

Rationale: There is increased risk of excessive hypotension if any of these drugs is combined with volatile liquid general anesthetics such as enflurane, halothane, or isoflurane. The effectiveness of diabetic agents is increased, leading to hypoglycemia when such agents are used with these drugs. Carvedilol has been associated with potentially dangerous conduction system disturbances when combined with verapamil or diltiazem. Vomiting is not associated with this combination of drugs. The nurse should communicate the patient’s medication history to the anesthesiologist to ensure safe administration of anesthesia.

Correct Answer: A

Rationale: Lithium is typically administered orally (PO) for long-term treatment of bipolar disorder. However, in emergency situations or cases of lithium toxicity where rapid control of symptoms is required, lithium can be administered via the intravenous (IV) route for faster absorption and effectiveness. IV administration allows for quick delivery of the medication directly into the bloodstream to achieve therapeutic levels promptly. It is essential to closely monitor lithium levels and kidney function when administering it intravenously to prevent potential complications.

Correct Answer: D

Rationale: In a patient with new-onset atrial fibrillation who requires rapid initiation of digoxin therapy, the fastest therapeutic effect would be achieved by administering the loading dose intravenously. Option D (Digoxin 1 mg IV push now; then 0.25 mg IV daily) includes an initial IV loading dose of 1 mg, followed by a maintenance dose of 0.25 mg IV daily. IV administration allows for quicker absorption and onset of action compared to oral administration. This loading dose increases the digoxin concentration in the bloodstream more rapidly, leading to a quicker therapeutic effect. Subsequent maintenance doses can then be given orally for long-term management.
