Question 1 of 5
A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, I am seeing a funny yellow color around the lights. What is the nurse™s next action?
Correct Answer: A
Rationale: The patient's statement about seeing a funny yellow color around the lights could be an early sign of digoxin toxicity. Digoxin toxicity can cause visual disturbances, such as seeing yellow or green halos around lights. Therefore, the nurse's next action should be to assess the patient for other symptoms of digoxin toxicity to determine the need for further intervention or medical attention.
Question 2 of 5
A 39-year-old man is a chronic alcoholic and is in and out of a rehabilitation center on a monthly basis. His physician administers a blocker of aldehyde dehydrogenase and the patient becomes violently ill with nausea, vomiting, chills, sweats, and hyperventilation. The same reaction occurs 1 week later after medication administration and was felt to be intolerable by the patient. Which of the following is the next best course of action to take?
Correct Answer: C
Rationale: The patient's severe reaction to disulfiram (aldehyde dehydrogenase blocker) suggests alcohol exposure, making it intolerable. Option continues the issue. Option intentionally triggers the reaction, unethical. Option , discontinuing disulfiram and starting naltrexone, is correct-naltrexone reduces alcohol cravings via opioid receptor antagonism, offering a safer alternative. Option , alprazolam, treats anxiety but not alcoholism. Option (E), psychotherapy, lacks immediate pharmacotherapy. Naltrexone addresses the root addiction without aversive effects, aligning with the patient's intolerance and chronic relapse pattern.
Question 3 of 5
Gold salt toxicity can be reversed using which medication?
Correct Answer: B
Rationale: Dimercaprol is a chelating agent used to treat heavy metal toxicity, including gold salt toxicity. It binds to the gold ions, forming a complex that can be excreted from the body. Acetaminophen, calcium salts, and hydroxocobalamin are not used for this purpose. Prompt administration of dimercaprol is essential to prevent severe complications of gold salt toxicity.
Question 4 of 5
The patient asks the nurse why she needs to continue using table salt because her prescribed lithium (Eskalith) is a salt. What is the best response by the nurse?
Correct Answer: D
Rationale: Lithium competes with sodium-adequate salt and hydration (1-1.5 L water) prevent toxicity by aiding excretion, per pharmacokinetics. Sea salt isn't less needed-sodium's the key. Retention isn't direct-hydration matters more. Increasing salt for toxicity is reactive, not preventive. Water trumps salt, clarifying use.
Question 5 of 5
The following are potential treatments for malignant hyperthermia:
Correct Answer: A
Rationale: Dantrolene is the drug of choice for malignant hyperthermia, as it reduces calcium release from the sarcoplasmic reticulum.
