The nurse has given medication instructions to a patient receiving phenytoin. Which statement by the patient indicates that the patient has an adequate understanding of the instructions?

"I will need to take extra care of my teeth and gums while on this medication."

"I will be able to stop taking this drug once the seizures stop."

"I can go out for a beer while on this medication."

"I can skip doses if the side effects bother me."

Answer and Explanation

The Correct Answer is A

A.   "I will need to take extra care of my teeth and gums while on this medication.": Phenytoin can cause gum overgrowth (gingival hyperplasia), so taking extra care of oral hygiene is important.
B.   "I will be able to stop taking this drug once the seizures stop.": Phenytoin is typically used as a long-term therapy for seizure control; stopping abruptly can lead to rebound seizures.
C.   "I can go out for a beer while on this medication.": Alcohol consumption may interact with phenytoin and should be avoided or limited.
D.   "I can skip doses if the side effects bother me.": Skipping doses of phenytoin can lead to inadequate seizure control and should not be done without consulting a healthcare provider.

Correct Answer is C

Explanation

A. CT of the brain can proceed regardless of atropine administration, as it does not directly affect the assessment of brain stem reflexes.
B. Electroencephalogram (EEG) can also proceed regardless of atropine administration, as it evaluates brain electrical activity rather than brain stem reflexes.
C. Assessment of brain stem reflexes should be postponed until all atropine is excreted and no

longer exerting its effects. Atropine can mask or alter the pupillary response and other brain stem reflexes, such as gag reflex and cough reflex, which are important indicators of neurological function.
D. Pupil response assessment should be postponed until atropine effects have dissipated, as

atropine can cause pupillary dilation, which may interfere with accurate assessment of pupil size and reactivity

A. Decreased urine output B. Increased cardiac output C. Volume restoration D. Reduced anxiety

Correct Answer is B

Explanation

A. Decreased urine output is not the primary intended effect of an adrenergic agonist in the

treatment of shock. While adrenergic agonists may increase blood pressure, leading to a decrease in urine output due to vasoconstriction, the primary goal of administering these drugs in shock is to improve tissue perfusion and cardiac output.
B. Increased cardiac output is the primary intended effect of adrenergic agonists in the treatment of shock. These medications stimulate adrenergic receptors, leading to increased heart rate, contractility, and stroke volume, ultimately improving cardiac output and tissue perfusion.
C. Volume restoration may be a secondary effect of administering fluids along with adrenergic agonists in the treatment of shock, but it is not the primary intended effect of the medication
itself.

D. Reduced anxiety is not a primary goal of administering adrenergic agonists in the treatment of shock. While these medications may have anxiolytic effects in certain situations, the primary goal is to improve cardiovascular function and tissue perfusion.
