Question 1 of 5
How can Ondansetron be administered? Select all that apply.
Correct Answer: A
Rationale: Ondansetron, commonly used to prevent nausea and vomiting, can be administered either orally (PO) or intravenously (IV). Both routes of administration are effective in delivering the medication to achieve the desired therapeutic effects. While options C (Subcutaneous) and D (IM) are not typically used for ondansetron administration, the correct answers are A (PO) and B (IV).
Question 2 of 5
Sedatives and hypnotics are drugs which act as:
Correct Answer: A
Rationale: Sedatives and hypnotics are drugs that belong to the class of central nervous system depressants. These drugs work by slowing down the activity of the brain and the central nervous system, leading to a calming or sedative effect. They are commonly prescribed to induce sleep (hypnotics) or reduce anxiety (sedatives) by depressing the excitability of nerve cells. This property makes them effective in producing sedation, relaxation, and sleep in individuals. Therefore, the correct classification for sedatives and hypnotics is as depressants.
Question 3 of 5
A nurse is instructing a client regarding carbidopa-levodopa (Sinemet) for the treatment of Parkinson’s disease. The nurse tells the client which of the following indicates an overdose of the medication?
Correct Answer: A
Rationale: An overdose of carbidopa-levodopa (Sinemet) can cause excessive dopaminergic stimulation, leading to dyskinesias or difficulty performing voluntary movements. Increased blood pressure, decreased appetite, and black tarry stools are not typical signs of overdose. Therefore, difficulty with voluntary movement is the correct indicator of overdose.
Question 4 of 5
A 56-year-old man with progressive, chronic renal impairment is awaiting renal replacement therapy. His treatment includes calcium carbonate tablets, furosemide, irbesartan and amlodipine. He is admitted severely unwell with a BP of 40 by palpation, pulse 112. An ECG shows a broad complex tachycardia with no P waves. Serum Ca2+ is 2.3 mmol/L, PO4 1.7 mmol/L, creatinine 785 μmol/L, Na+ 142 mmol/L, K+ 7.4 mmol/L. Which of the following would be appropriate management?
Correct Answer: C
Rationale: Severe hyperkalemia (K+ 7.4 mmol/L) in renal failure causes broad complex tachycardia, risking arrest. Amiodarone treats arrhythmias but not hyperkalemia's cause. Digoxin is contraindicated in hyperkalemia and renal failure. IV calcium gluconate stabilizes cardiac membranes, countering potassium's depolarizing effect, appropriate immediate management. Pacing or colestyramine (potassium binder) are secondary. Calcium's rapid action protects the heart, buying time for dialysis, critical in this life-threatening scenario.
Question 5 of 5
A client is receiving methocarbamol (Robaxin) as an adjunct to physical therapy for the relief of painful muscle discomfort. Which of the following is not true regarding the use of the medication?
Correct Answer: C
Rationale: Methocarbamol can cause urine discoloration, and rapid intravenous administration may lead to hypotension and bradycardia. However, the use of cold or allergy medicines does not lessen its side effects. The parenteral form is contraindicated in patients with liver damage due to the risk of hepatotoxicity. This statement is incorrect and not supported by the drug's pharmacology.
