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 is indicative of potential digoxin toxicity, as digoxin can cause visual disturbances, such as changes in color vision. The nurse should assess the patient for other symptoms of digoxin toxicity, which may include nausea, vomiting, confusion, and changes in heart rate. It is important to evaluate the patient's condition further to determine the appropriate course of action, including the need for further evaluation and potentially withholding the next dose of digoxin.

Correct Answer: D

Rationale: The peak range of regular insulin typically occurs between 1 to 5 hours after administration. This means that regular insulin will reach its maximum effectiveness in lowering blood sugar levels during this time frame. Patients should be aware of this peak range to help manage their diabetes effectively and time their meals and activities accordingly.

Correct Answer: A

Rationale: Furosemide is a diuretic medication that works in the loop of Henle in the kidneys to increase the excretion of water and electrolytes such as sodium and potassium. Its therapeutic effects include increasing the production of urine, reducing fluid retention, and lowering blood pressure. Due to its diuretic properties, furosemide is commonly prescribed for conditions such as edema (fluid retention) associated with congestive heart failure, liver disease, and kidney disorders.

Correct Answer: D

Rationale: Alcohol dehydrogenase (ADH) metabolizes ethanol to acetaldehyde and is inhibited by fomepizole , used in poisonings. It doesn't act on acetaldehyde or acetate . Disulfiram blocks aldehyde dehydrogenase. ADH's role initiates ethanol breakdown.

Correct Answer: A

Rationale: Benzodiazepines are a class of psychoactive drugs that primarily work by enhancing the effect of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter that reduces the activity of nerve cells, resulting in a calming effect on the central nervous system. By increasing GABA activity, benzodiazepines help reduce feelings of anxiety and produce sedation or relaxation. This is why the correct answer is that all benzodiazepines reduce anxiety and produce sedation.
