Question 1 of 5
The major electrolytes in the extracellular fluid are:
Correct Answer: C
Rationale: Sodium and chloride are the major electrolytes in the extracellular fluid.
Question 2 of 5
The nurse is reviewing documentation on four clients prior to administering medications. The nurse should immediately withhold the medication and notify the HCP about which client?
Correct Answer: D
Rationale: Client 4's symptoms of tardive dyskinesia (lip smacking, uncontrolled rhythmic movements) may be irreversible, requiring immediate medication withdrawal and HCP notification.
Question 3 of 5
Which of the following actions should the LPN perform for a client with an active digoxin IV order? Select all that apply. A. Monitor ECG rhythm throughout administration., B. Administer the medication over at least 5 minutes., C. Monitor respirations during administration., D. Monitor the client's pulse for 1 minute prior to administration., E. Assess the client's blood pressure.
Correct Answer: A
Rationale: The LPN should monitor the client's heart rate and ECG with digoxin administration. Digoxin should not be given if a client's pulse is less than 60 bpm. Measuring blood pressure and respiratory rate are not indicated with digoxin administration. Administering an IV medication is outside of the LPN's scope of practice.
Question 4 of 5
A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?
Correct Answer: C
Rationale: Furosemide, a diuretic, commonly causes potassium loss, leading to hypokalemia, which can potentiate digitalis toxicity, requiring close monitoring.
Question 5 of 5
The nurse administered phenylephrine eye drops to the client before performing an ophthalmoscopic eye examination. Which assessment finding should the nurse expect?
Correct Answer: D
Rationale: A: Tremors are a side effect if phenylephrine is absorbed systemically. B: Because phenylephrine absorbed systemically is a vasoconstrictor, hypertension (not hypotension) can occur as a side effect. C: Miosis is pupil constriction, not an effect of phenylephrine. D: Phenylephrine (NeoSynephrine), an adrenergic agonist, produces pupil dilation (mydriasis) by activating alpha1-adrenergic receptors on the dilator muscles of the iris.
