LPN Pharmacology Practice Questions
1. A client with atrial fibrillation is prescribed warfarin (Coumadin). Which instruction should the nurse give to the client regarding lifestyle changes?
- A. Avoid prolonged sitting or standing.
- B. Use an electric razor to prevent cuts.
- C. Take your medication with a full glass of water.
- D. Eat a diet low in protein.
Correct answer: B
Rationale: The correct answer is B. Using an electric razor is advised to prevent cuts, which is crucial for individuals taking warfarin due to the increased risk of bleeding associated with this medication. Lifestyle changes related to warfarin therapy focus on minimizing the risk of bleeding, and using safety measures such as an electric razor is a practical recommendation to reduce the likelihood of injury. Choices A, C, and D are incorrect. Avoiding prolonged sitting or standing is more related to preventing blood clots than to the bleeding risk of warfarin. Taking warfarin with a full glass of water is not a specific lifestyle change associated with its use. Eating a diet low in protein is not a typical recommendation for individuals on warfarin therapy.
2. What is the primary function of carbohydrates as a food source?
- A. Regulate metabolic processes.
- B. Build body tissue.
- C. Supply energy.
- D. Provide bulk.
Correct answer: C
Rationale: The primary function of carbohydrates as a food source is to supply energy. Carbohydrates are the body's main source of energy, providing fuel for various physiological functions. Choice A is incorrect because carbohydrates do not primarily regulate metabolic processes; that role is mainly attributed to enzymes and hormones. Choice B is incorrect because proteins are primarily responsible for building body tissue. Choice D is incorrect because fiber, not all carbohydrates, provides bulk in the diet.
3. A client just received their first dose of lisinopril. Which of the following is an appropriate nursing intervention?
- A. Place the client on cardiac monitoring
- B. Monitor the client’s oxygen saturation
- C. Provide standby assistance when the client gets out of bed
- D. Encourage foods high in potassium
Correct answer: C
Rationale: The correct answer is to provide standby assistance when the client gets out of bed. Lisinopril can cause hypotension, especially after the first dose, which can lead to dizziness and falls. Standby assistance helps prevent potential injury. Placing the client on cardiac monitoring (choice A) or monitoring oxygen saturation (choice B) are not typically necessary after the first dose of lisinopril unless specific symptoms are present. Encouraging foods high in potassium (choice D) is not directly related to the immediate concern of postural hypotension associated with lisinopril.
4. Which hormone is responsible for stimulating the gallbladder to contract and release bile?
- A. gastric lipase
- B. cholecystokinin
- C. vitamin D
- D. enterokinin
Correct answer: B
Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.
5. In a unionized hospital, nurses receive compensatory pay for working holidays based on the hours worked with no extra compensation. Despite management refusing to consider changes to the compensatory pay system suggested by nurses during the annual employee satisfaction survey, a trend member listened to both parties and made non-legally binding recommendations. What is this type of settlement known as?
- A. Collective bargaining
- B. Mediation
- C. Grievance
- D. Binding arbitration
Correct answer: B
Rationale: Mediation involves a neutral third party who assists in resolving disputes by providing non-legally binding recommendations. In this scenario, the trend member acted as a mediator by listening to both nurses and management and offering suggestions without the authority to enforce them as a legally binding decision. Collective bargaining refers to negotiations between labor unions and employers to determine terms of employment. Grievance is a formal complaint by an employee against an employer. Binding arbitration involves a neutral third party making a final and legally binding decision to resolve a dispute.
