When monitoring a patient who is taking a cholinergic drug, the nurse will watch for which cardiovascular effect?
Tachycardia
Palpitations
Vasoconstriction
Bradycardia
The Correct Answer is D
A. Tachycardia is not typically associated with cholinergic drug effects. Cholinergic stimulation tends to slow down the heart rate rather than increase it.
B. Palpitations may occur with certain cardiac arrhythmias or in response to sympathetic stimulation, but they are not typically associated with cholinergic drug effects.
C. Cholinergic drugs are more likely to cause vasodilation rather than vasoconstriction.
Therefore, vasoconstriction is not a common cardiovascular effect of cholinergic drug therapy.
D. Bradycardia is a common cardiovascular effect of cholinergic drug therapy. Cholinergic stimulation slows down the heart rate by increasing parasympathetic activity, particularly at the
sinoatrial (SA) node. Therefore, bradycardia is the cardiovascular effect that nurses should monitor for when administering cholinergic drugs.

Correct Answer is B
Explanation
A. A lithium level of 0.9 mEq/L falls within the therapeutic range for lithium, so it is not too low.
B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.
C. Lithium is commonly monitored with blood levels to ensure therapeutic efficacy and to prevent toxicity.
D. A lithium level of 0.9 mEq/L is not too high; it is within the therapeutic range.
Correct Answer is A
Explanation
A. Midazolam: Benzodiazepine with rapid onset of action, often preferred for acute seizure management such as status epilepticus.
B. Carbamazepine: Not typically used for acute seizure management like status epilepticus; more commonly used for maintenance therapy in epilepsy.
C. Diazepam: Benzodiazepine also used for acute seizure management, including status epilepticus. However, midazolam is often preferred due to its faster onset and shorter duration.
D. Valproic acid: Effective for long-term seizure control but not typically used for acute seizure management such as status epilepticus.
