Extract:

Question 1 of 5

The client is experiencing supraventricular tachycardia (SVT). Which antidysrhythmic medication should the nurse prepare to administer?

Correct Answer: C

Rationale: Adenosine is first-line for SVT, rapidly terminating the arrhythmia, per ACLS guidelines. Other drugs are used for different rhythms.

Question 2 of 5

A 13-month-old child is admitted to the emergency room with salicylate poisoning. Her mother found her beside the empty bottle of adult aspirin. She says there were 'about 10' aspirin left in the bottle. What manifestations would the nurse most expect to see in the child?

A. Bradypnea and pallor B. Hyperventilation and hyperpyrexia C. Subnormal temperature and bleeding D. Melena and bradycardia

Correct Answer: B

Rationale: Salicylate poisoning causes metabolic acidosis, leading to hyperventilation, and stimulates the CNS, causing fever (hyperpyrexia).

Question 3 of 5

The nurse administered an IV broad-spectrum antibiotic scheduled every six (6) hours to the client with a systemic infection at 0800. At 1000, the culture and sensitivity prompted the HCP to change the IV antibiotic. When transcribing the new antibiotic order, when would the initial dose be administered?

A. Schedule the dose for 1400. B. Schedule the dose for the next day. C. Check with the HCP to determine when to start. D. Administer the dose within one (1) hour of the order.

Correct Answer: D

Rationale: New antibiotic orders for active infections require prompt administration (within 1 hour) to maintain therapeutic levels, per sepsis guidelines.

Question 4 of 5

The nurse is preparing to administer phenytoin (Dilantin), 100 mg intravenous push, to the client with a head injury who has an IV of D5W at 50 mL/hr. Which intervention should the nurse implement?

A. Flush the IV tubing before and after with normal saline. B. Administer the medication if the Dilantin level is 22 mcg/mL. C. Push the Dilantin intravenously slowly over five (5) minutes. D. Expect the intravenous tubing to turn cloudy when infusing medication.

Correct Answer: A

Rationale: Phenytoin is incompatible with D5W; saline flush prevents precipitation. Level of 22 mcg/mL is toxic, slow push is correct but not primary, and cloudiness is avoidable.

Question 5 of 5

The client diagnosed with adult-onset asthma is being discharged. Which medication would the nurse expect the health-care provider to prescribe?

A. A nonsteroidal anti-inflammatory medication. B. An antihistamine medication. C. An angiotensin-converting enzyme inhibitor. D. A proton pump inhibitor.

Correct Answer: None

Rationale: Asthma typically requires bronchodilators (e.g., albuterol) or steroids, not listed. None of the options are standard asthma treatments.
