1. A client is receiving IV Dopamine for the treatment of shock. Which of the following findings indicates that the medication is effective?
- A. Increased heart rate
- B. Decreased blood pressure
- C. Increased urine output
- D. Decreased respiratory rate
Correct answer: C
Rationale: Dopamine is a medication used in shock to increase cardiac output and improve renal perfusion. An increase in urine output indicates that the medication is effective as it shows improved renal perfusion and kidney function, which are essential for managing shock effectively. Choices A, B, and D are incorrect as an increased heart rate, decreased blood pressure, and decreased respiratory rate are not direct indicators of the effectiveness of IV Dopamine in treating shock.
2. A client has been prescribed Warfarin for atrial fibrillation. Which of the following instructions should the nurse include in the discharge teaching?
- A. Avoid foods high in vitamin K.
- B. Take this medication with food to prevent nausea.
- C. Monitor your heart rate daily before taking the medication.
- D. Limit your fluid intake to 1 liter per day.
Correct answer: A
Rationale: The correct instruction for the nurse to include in the discharge teaching for a client prescribed Warfarin is to 'Avoid foods high in vitamin K.' Foods high in vitamin K can decrease the effectiveness of Warfarin by interfering with its anticoagulant effects, potentially leading to blood clotting issues. It is crucial for clients on Warfarin therapy to maintain a consistent intake of vitamin K-containing foods to ensure the stability of the medication's effects. Choices B, C, and D are incorrect because taking Warfarin with food, monitoring heart rate daily, or limiting fluid intake are not directly related to optimizing the effectiveness of Warfarin therapy.
3. Which drug is the antidote for Alprazolam?
- A. Physostigmine
- B. Protamine sulfate
- C. Flumazenil
- D. Acetylcysteine
Correct answer: C
Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.
4. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
5. When educating a patient on taking levothyroxine, a drug used to balance thyroid activity, what should you include in their education?
- A. Don't disregard side effects and consult your healthcare professionals
- B. Take this at the same time every day
- C. Thyroid tests are necessary while taking this drug
- D. It is not recommended to take this drug if you have recently had a myocardial infarction
Correct answer: B
Rationale: The correct answer is to take levothyroxine at the same time every day. Consistent timing helps maintain stable thyroid levels, ensuring the effectiveness of the medication. It is important to establish a routine to optimize its therapeutic benefits. Choice A is incorrect as patients should not ignore side effects but should consult healthcare professionals if they experience any. Choice C is incorrect because thyroid tests may still be necessary to monitor thyroid function while on levothyroxine. Choice D is incorrect as it is not advisable to take levothyroxine if the patient has recently had a myocardial infarction without consulting their healthcare provider.
