1. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?
- A. Lowered heart rate
- B. Increased myocardial contractility
- C. Decreased conduction through the AV node
- D. Vasoconstriction of renal blood vessels
Correct answer: B
Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.
2. When providing discharge instructions to a client prescribed Prednisone, which of the following dietary instructions should the nurse include?
- A. Increase your intake of potassium-rich foods.
- B. Increase your intake of dairy products.
- C. Avoid foods high in vitamin K.
- D. Decrease your intake of protein.
Correct answer: A
Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods. Prednisone can lead to potassium depletion, making it essential to consume foods high in potassium, such as bananas, oranges, and spinach, to maintain electrolyte balance and prevent complications. Choice B is incorrect because increasing dairy products is not specifically necessary when taking Prednisone. Choice C is wrong as foods high in vitamin K are not contraindicated with Prednisone. Choice D is incorrect as there is no need to decrease protein intake when prescribed Prednisone.
3. A client in the operating room received a dose of Succinylcholine. During the operation, the client suddenly develops rigidity, and their body temperature begins to rise. The healthcare provider should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: C
Rationale: Muscle rigidity and a sudden rise in temperature are manifestations of malignant hyperthermia. Dantrolene acts on skeletal muscles to reduce metabolic activity and treat malignant hyperthermia effectively. Neostigmine (choice A) is used to reverse the effects of non-depolarizing neuromuscular blockers, not to treat malignant hyperthermia. Naloxone (choice B) is an opioid antagonist used for opioid overdose. Vecuronium (choice D) is a non-depolarizing neuromuscular blocker and is not used to treat malignant hyperthermia.
4. A client has ordered a thrombolytic medication for the treatment of CVA. Which type of stroke should not be treated with a thrombolytic?
- A. Hemorrhagic stroke
- B. Thrombotic stroke
- C. Both types can be treated with a thrombolytic
- D. Neither type can be treated with a thrombolytic
Correct answer: A
Rationale: Thrombolytic medications are used to dissolve blood clots. In the case of a hemorrhagic stroke, where there is bleeding in the brain, the use of thrombolytics can worsen the condition by increasing bleeding. Therefore, hemorrhagic strokes should not be treated with thrombolytic medications.
5. A client is being educated by a healthcare provider about a new prescription for Digoxin. Which of the following client statements indicates an understanding of the teaching?
- A. I will take the medication with a high-fiber meal.
- B. I should report any vision changes to my healthcare provider.
- C. I will take the medication if my heart rate is below 60 bpm.
- D. I should avoid dairy products while taking this medication.
Correct answer: B
Rationale: The correct answer is B. Visual disturbances, such as blurred vision or seeing halos, can be a sign of digoxin toxicity. It is crucial for the client to report any changes in vision to their healthcare provider promptly to prevent serious complications. Choice A is incorrect because taking Digoxin with a high-fiber meal can affect its absorption. Choice C is incorrect because taking Digoxin based on heart rate alone is not recommended without healthcare provider supervision. Choice D is incorrect because there is no specific interaction between Digoxin and dairy products.
