A. Hypotension
The combination of nitroglycerin and sildenafil can lead to severe hypotension due to the vasodilatory effects of both medications. This is the most critical adverse reaction the nurse should anticipate.
B. Bradycardia
Bradycardia is not a direct effect of this combination; rather, hypotension is a more significant concern.
C. Chest pain
Chest pain may occur if hypotension leads to inadequate perfusion, but it is not a direct adverse effect of the drug interaction.
D. Nausea
Nausea can occur with various medications, but it is not specifically linked to the interaction between nitroglycerin and sildenafil.

Convert to equivalents within the metric system. 250 micrograms to grams
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.
