1. A healthcare professional is reviewing a client's health record and notes that the client experiences permanent extrapyramidal effects caused by a previous medication. The healthcare professional should recognize that the medication affected which of the following systems in the client?
- A. Cardiovascular
- B. Immune
- C. Central nervous
- D. Gastrointestinal
Correct answer: C
Rationale: The correct answer is C: Central nervous. Extrapyramidal effects are movement disorders caused by certain medications affecting the central nervous system. These effects can include symptoms like tremors, rigidity, and bradykinesia. Medications like typical antipsychotics induce extrapyramidal effects by interfering with dopamine transmission in the central nervous system. Choices A, B, and D are incorrect as extrapyramidal effects are specifically related to the central nervous system and not the cardiovascular, immune, or gastrointestinal systems.
2. What nursing interventions should you perform when a patient is on Albuterol? (Select all that apply)
- A. Assess lung sounds, pulse, and blood pressure before administering
- B. Monitor for changes in behavior
- C. Observe for paradoxical bronchospasms
- D. Both A and C
Correct answer: D
Rationale: The correct nursing interventions to perform when a patient is on Albuterol include assessing the patient's lung sounds, pulse, and blood pressure before administering the medication to monitor for cardiovascular side effects like increased heart rate. Additionally, it is crucial to observe for paradoxical bronchospasms, a rare but serious adverse reaction where the medication causes a worsening of bronchospasm instead of relief. Monitoring for changes in behavior is not directly related to Albuterol administration and is not a standard nursing intervention for patients receiving this medication, making choice B incorrect. Therefore, the correct answer is D as it includes the essential nursing actions for patients on Albuterol.
3. Which of the following is considered a class IA Sodium Channel blocker?
- A. Mexiletine
- B. Amiodarone
- C. Quinidine
- D. Procainamide
Correct answer: D
Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.
4. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?
- A. Hemoglobin
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.
5. Which of the following is classified as a class IA Sodium Channel blocker?
- A. Quinidine
- B. Disopyramide
- C. Aminodarone
- D. Propafenone
Correct answer: A
Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
