The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?

Correct Answer: C

Rationale: Grapefruit juice can interfere with the effectiveness of digoxin by inhibiting the enzyme responsible for metabolizing the drug in the body. This interaction can lead to increased levels of digoxin in the bloodstream, potentially causing harmful effects such as toxicity. It is important for patients taking digoxin to avoid consuming grapefruit juice to ensure the medication works as intended.

Correct Answer: C

Rationale: Alprazolam (Xanax) is a medication commonly used to treat anxiety disorders and panic attacks. It belongs to a class of medications known as benzodiazepines, which work by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. This helps to reduce the excessive activity in the brain that can lead to anxiety and panic symptoms. Alprazolam is fast-acting and can provide relief from panic attacks quickly.

Correct Answer: C

Rationale: Teriflunomide, used in multiple sclerosis, inhibits dihydroorotate dehydrogenase, blocking pyrimidine synthesis critical for lymphocyte proliferation, reducing CNS inflammation by limiting activated immune cells. Riluzole modulates glutamate for ALS, not immunity. Rotigotine, a dopamine agonist, treats Parkinson's. Dexamethasone, a corticosteroid, suppresses inflammation broadly via glucocorticoid pathways, not pyrimidine-specific mechanisms. Teriflunomide's targeted action on lymphocyte replication distinguishes it in MS, decreasing relapses by curbing immune-mediated damage, a precise fit for this description.

Correct Answer: A

Rationale: Body image concerns in adolescents often tie to eating-defensiveness about food scrutiny suggests disordered eating (e.g., anorexia), linking pain to image stress. Sexual activity, irregular periods, or parent conflicts point elsewhere-STI, hormonal issues, or family tension. Food focus signals image worry, per developmental psychology.

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.
