Full Explanation
1 gram = 1,000,000 micrograms
Therefore, 250 micrograms = 250 / 1,000,000 grams = 0.00025 grams

A client previously experienced a severe anaphylactic reaction to penicillin G. Which medication class should not be administered to this client due to the potential for cross-sensitivity?
A. Nitrates
Nitrates do not share a cross-sensitivity with penicillin and are safe to use in this client.
B. Tetracycline
Tetracycline is a different class of antibiotics and does not have cross-sensitivity with penicillin.
C. Aminoglycoside
Aminoglycosides also do not have cross-sensitivity with penicillin and can be safely administered.
D. Cephalosporins
Cephalosporins are structurally related to penicillin and have a risk of cross-sensitivity; thus, they should not be given to a client with a history of anaphylaxis to penicillin.

A nurse is caring for a patient who is receiving both short-acting and intermediate-acting insulin. The nurse should understand that:
A. The short-acting insulin covers the patient's basal needs.
Short-acting insulin does not cover basal needs; that is the role of long-acting insulin.
B. The intermediate-acting insulin covers mealtime glucose spikes.
Intermediate-acting insulin does not primarily cover mealtime glucose spikes; it provides a more prolonged effect.
C. The short-acting insulin provides coverage for meals, while intermediate-acting insulin covers glucose control between meals and overnight.
Short-acting insulin is used to manage blood glucose during meals, while intermediate-acting insulin helps maintain glucose control between meals and overnight, making this the correct choice.
D. Both types of insulin have the same onset and peak times.
Short-acting and intermediate-acting insulins have different onset and peak times; they do not share the same pharmacokinetic properties.

What client is most likely to have impaired drug metabolism?
A. A client who has a diagnosis of hepatitis C
Clients with hepatitis C experience liver impairment, which is crucial for drug metabolism; hence, they are likely to have impaired drug metabolism.
B. A client who is being treated for basal cell skin cancer
Treatment for basal cell skin cancer typically does not affect liver function significantly, so drug metabolism is less likely to be impaired.
C. A client who requires dialysis for renal failure
Clients requiring dialysis have impaired renal function, affecting drug excretion more than metabolism, so they may not necessarily have impaired drug metabolism.
D. A client who is dehydrated following several days of diarrhea
Dehydration following diarrhea can affect the body's overall function, but it is less directly related to impaired drug metabolism compared to liver dysfunction.
