Alcoholic or hydroalcoholic solution of volatile substances
- A. decoction
- B. fluid extract
- C. solution
- D. spirits
Correct Answer: D
Rationale: A spirit is an alcoholic or hydroalcoholic solution of volatile substances obtained by distillation. It is commonly used in the production of alcoholic beverages and in the pharmaceutical industry for preparing tinctures and extracts. Spirits are characterized by their high alcohol content and ability to extract and preserve the properties of the substances they are derived from. Decoction is a method of extracting compounds from plants using boiling water, fluid extract is a concentrated liquid extract of a substance, solution refers to a homogeneous mixture of substances, and syrup is a thick, sweet liquid usually made by dissolving sugar in water.

Which of the following should be monitored for patients taking diuretics? (select all that apply)
- A. Daily weight
- B. Intake and output
- C. Amount and location of edema
- D. Appetite
Correct Answer: A
Rationale: A. Daily weight should be monitored for patients taking diuretics because diuretics can cause fluid loss which may lead to weight changes. Fluctuations in weight can indicate changes in fluid balance and help determine the effectiveness of the diuretic therapy.
The nurse notes in the patient™s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder?
- A. Ventricular ectopy
- B. Atrial fibrillation
- C. Supraventricular tachycardia
- D. Bradycardia
Correct Answer: B
Rationale: Ibutilide (Corvert) is a medication commonly used to treat atrial fibrillation, a type of irregular heart rhythm that originates in the heart's upper chambers (atria). It works by restoring normal heart rhythm in patients with atrial fibrillation. Therefore, the nurse notes the use of ibutilide in the patient's medication orders, indicating that the patient has atrial fibrillation.
The nurse observes a short period of asystole on the cardiac monitor that resolves spontaneously immediately after administering adenosine IV to a patient who was experiencing paroxysmal supraventricular tachycardia. Which initial action is the most appropriate for the nurse?
- A. Call a code to report a cardiac arrest.
- B. Prepare epinephrine and atropine for intravenous administration.
- C. Initiate cardiopulmonary resuscitation (CPR).
- D. Closely observe the patient and the cardiac monitor.
Correct Answer: D
Rationale: Adenosine is used to treat paroxysmal supraventricular tachycardia (PSVT) by temporarily blocking AV node conduction, which can cause a brief period of asystole. This is an expected effect and typically resolves spontaneously. The nurse should closely monitor the patient and the cardiac monitor for the return of a normal rhythm. Calling a code (A), preparing epinephrine and atropine (B), or initiating CPR (C) is unnecessary unless the asystole persists or the patient becomes unstable.
Which nursing diagnosis is appropriate for a patient receiving antidysrhythmics?
- A. Risk for infection
- B. Deficient knowledge
- C. Deficient fluid volume
- D. Urinary retention
Correct Answer: C
Rationale: The appropriate nursing diagnosis for a patient receiving antidysrhythmics would be Deficient fluid volume. Antidysrhythmics can have side effects such as electrolyte imbalances, which can lead to fluid volume deficit. Monitoring the patient's fluid intake and output is crucial to prevent dehydration and maintain proper electrolyte balance. Therefore, identifying Deficient fluid volume as a nursing diagnosis allows for appropriate interventions to be implemented to address and prevent this potential complication.
Reye's syndrome, a potentially fatal illness associated with liver failure and encephalopathy is associated with the administration of which over-the-counter (OTC) medication?
- A. acetaminophen (Tylenol)
- B. ibuprofen (Motrin)
- C. aspirin
- D. brompheniramine/pseudoephedrine (Dimetapp)
Correct Answer: C
Rationale: Reye's syndrome is linked to the use of aspirin in children and adolescents, particularly during viral infections. It causes severe liver and brain damage. Acetaminophen, ibuprofen, and antihistamines are not associated with this condition. Avoiding aspirin in pediatric patients is critical to prevent this rare but life-threatening syndrome.
