LPCC Pharmacology Fundamentals 2

Question 1

A client on lithium reports tremors, nausea, and blurred vision. The serum lithium level is 1.8 mEq/L. What is the clinical priority?

Accepted Answer

Hold the next dose and contact the prescribing physician immediately

Answer

A lithium level of 1.8 mEq/L exceeds the therapeutic range (0.6–1.2 mEq/L) and indicates early toxicity requiring immediate medical consultation.

Question 2

Which neurotransmitter is primarily targeted by SSRIs to reduce symptoms of depression?

Accepted Answer

Serotonin

Answer

SSRIs block the reuptake of serotonin at the presynaptic neuron, increasing serotonin availability in the synaptic cleft.

Question 3

A client taking a monoamine oxidase inhibitor (MAOI) consumes aged cheese at dinner. What reaction is most likely to occur?

Accepted Answer

Hypertensive crisis

Answer

Tyramine in aged cheese cannot be metabolized when MAO is inhibited, causing a dangerous release of norepinephrine and a hypertensive crisis.

Question 4

Which class of medications is most commonly associated with the risk of developing tardive dyskinesia with long-term use?

Accepted Answer

First-generation antipsychotics

Answer

First-generation (typical) antipsychotics block D2 dopamine receptors and carry the highest risk of tardive dyskinesia with prolonged use.

Question 5

A prescriber orders clonazepam for a client with panic disorder. Under what schedule does this substance fall under the DEA?

Accepted Answer

Schedule IV

Answer

Clonazepam, like other benzodiazepines, is classified as a Schedule IV controlled substance due to its lower but existing potential for abuse and dependence.
