Accepted Answer

Clarify the nature of the penicillin allergy with the patient and provider before administration

Cross-reactivity between penicillins and cephalosporins exists, especially with anaphylactic penicillin reactions; the nurse must clarify the type of allergy and consult the provider.

Question 2

A nurse notes that a patient's morning potassium is 3.0 mEq/L. The patient is also taking digoxin. The nurse should:

Accepted Answer

Hold the digoxin and notify the provider of the potassium level

Answer

Hypokalemia increases sensitivity to digoxin toxicity; the medication should be withheld and the provider notified for potassium correction orders.

Question 3

Which assessment finding would prompt the nurse to hold a scheduled dose of morphine?

Accepted Answer

Respiratory rate of 10 breaths/min

Answer

A respiratory rate below 12 breaths/min indicates opioid-induced respiratory depression, requiring the nurse to hold the medication and notify the provider.

Question 4

A patient is prescribed phenytoin (Dilantin) IV. Which solution is compatible for administration?

Accepted Answer

Normal saline (0.9% NaCl)

Phenytoin precipitates in dextrose-containing solutions and must be administered in normal saline (0.9% NaCl) only.
