Question 1 of 5
A liquid preparation of K penicillin V contains 125mg/5ml. If you want a patient to take 250mg. each dose, you would prescribe ___ per
Correct Answer: C
Rationale: To prescribe 250mg of K penicillin V, you would need to have 10ml of the liquid preparation (125mg/5ml x 10ml = 250mg). Since 1 teaspoon (tsp) is approximately equal to 5ml, you would need to prescribe 2 teaspoons of the liquid preparation for the patient to take 250mg per dose.
Question 2 of 5
The client is receiving a brand name drug and wants to change to the generic form because it is cheaper. What is the best outcome for this client?
Correct Answer: A
Rationale: Understanding two differences (e.g., cost, inactive ingredients) between brand and generic drugs empowers the client to make informed choices, the best outcome. Sticking to brand after physician talk assumes preference. Asking why brand is better misaligns-generics are equivalent. Cost reduction methods are practical but secondary to comprehension. Knowledge of differences supports the switch, aligning with cost-saving goals.
Question 3 of 5
A patient has been diagnosed with tuberculosis and is to begin antitubercular therapy with isoniazid, rifampin, and ethambutol. Which actions are appropriate for the nurse to do? (Select all that apply.)
Correct Answer: A
Rationale: Ethambutol can cause optic neuritis, so periodic eye examinations are essential. Taking medications with meals can help reduce gastrointestinal side effects. Antacids should be avoided as they can interfere with drug absorption. Numbness and tingling of the hands or feet may indicate peripheral neuropathy, a side effect of isoniazid, and should be reported promptly.
Question 4 of 5
A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, I am seeing a funny yellow color around the lights. What is the nurse™s next action?
Correct Answer: A
Rationale: The patient's statement about seeing a funny yellow color around the lights is indicative of potential digoxin toxicity, as digoxin can cause visual disturbances, such as changes in color vision. The nurse should assess the patient for other symptoms of digoxin toxicity, which may include nausea, vomiting, confusion, and changes in heart rate. It is important to evaluate the patient's condition further to determine the appropriate course of action, including the need for further evaluation and potentially withholding the next dose of digoxin.
Question 5 of 5
Which of the following is most effective as a topical agent for a candida infection of the skin?
Correct Answer: D
Rationale: Cutaneous candidiasis needs topical antifungals. Griseofulvin treats dermatophytes orally, not candida topically. Beclometasone, a steroid, worsens fungal growth. Aciclovir targets herpes, not fungi. Amphotericin is IV for systemic use. Nystatin binds ergosterol in candida membranes, most effective topically for skin infections, widely used for its specificity and safety.
