Extract:
Question 1 of 5
A nurse is teaching a client with angina pectoris about starting therapy with nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: A
Rationale: Nitroglycerin is administered sublingually for rapid absorption to relieve chest pain. The standard instruction is to take one tablet every 5 minutes up to 3 doses if chest pain persists, then seek medical help if unrelieved.
Question 2 of 5
The nurse notes a client in supraventricular tachycardia. The patient has a pulse and the cardiac monitor is at the bedside. The nurse understands electrical intervention is indicated. What button does the nurse push to ensure the electricity is delivered on the R wave? Refer to the picture.

Correct Answer: D
Rationale: Synchronized cardioversion delivers a shock on the R wave to avoid the vulnerable T wave period, reducing the risk of inducing ventricular fibrillation. The SYNC button ensures this timing.
Question 3 of 5
A nurse is caring for a client that is post cardiopulmonary arrest. The nurse anticipates to administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?
Correct Answer: B
Rationale: Atropine is the first-line medication for symptomatic bradycardia as it increases heart rate by blocking vagal activity on the SA node.
Question 4 of 5
A nurse is caring for a client who has a serum potassium level of 5.9 mEq/L. The provider prescribes polystyrene sulfonate. If this medication is effective, the nurse should expect which of the following changes on the client's ECG?
Correct Answer: C
Rationale: Polystyrene sulfonate reduces serum potassium levels. Hyperkalemia causes peaked T waves on an ECG, so effective treatment would result in a reduction of this abnormality.
Question 5 of 5
A client with a complaint of dehydration has been admitted into the medical floor. Sodium chloride 1000 ml IV to infuse over 12 hrs has been ordered by the admitting Physician. How many ml/hr should you administer? (Round to the nearest whole number) ml/hr
Correct Answer: 83
Rationale:
To calculate the infusion rate: 1000 ml ÷ 12 hrs = 83.33 ml/hr, rounded to 83 ml/hr.
