Psychiatric-Mental Health Nurse Practitioner (PMHNP) Exam Revision Guide
Questions, Correct Answers & Rationales
1. An 18-year-old patient diagnosed with bipolar disorder wants to enter a research study that
will test an experimental drug. The psychiatric-mental health nurse practitioner's initial
response is:
A. "All drug treatments are too risky for you at this time."
B. "Let's discuss the risks of potentially changing your medications."
C. "We will have to see if you meet the inclusion criteria for this research study."
D. "You will have only a small chance of receiving the experimental drug."
Correct Answer: C. "We will have to see if you meet the inclusion criteria for this research
study."
Rationale:
Before discussing risks or benefits of an experimental medication, the provider must first
determine whether the patient qualifies for participation. Research studies have specific
inclusion and exclusion criteria that must be evaluated before enrollment.
• A: Incorrect — dismisses the patient's request and does not support autonomy.
• B: Incorrect — medication risk discussion occurs after eligibility is established.
• D: Incorrect — the patient may or may not receive the experimental drug depending on
study design.
,2. A 14-year-old patient has nonspecific reports of pain in their legs. The physical examination
is unremarkable. Laboratory results are within normal limits except for a markedly elevated
alkaline phosphatase level. The psychiatric-mental health nurse practitioner:
A. interprets the findings as normally occurring during a rapid adolescent growth spurt.
B. obtains a rheumatoid profile because elevated alkaline phosphatase is a sign of early
rheumatic fever.
C. orders a repeat blood test.
D. suspects that the patient has acute pancreatitis.
Correct Answer: A. interprets the findings as normally occurring during a rapid adolescent
growth spurt.
Rationale:
During adolescence, alkaline phosphatase levels commonly increase because of rapid bone
growth and increased osteoblastic activity. In the absence of abnormal findings, this elevation
is usually a normal developmental finding.
• B: Incorrect — alkaline phosphatase elevation is not a diagnostic marker for rheumatic
fever.
• C: Incorrect — repeat testing is unnecessary when the elevation matches normal
growth.
• D: Incorrect — pancreatitis is associated with elevated amylase and lipase, not isolated
alkaline phosphatase.
3. Laboratory findings for a patient with an alcohol use disorder indicate increased liver
function values and:
A. decreased mean corpuscular volume (MCV) and normal triglyceride levels.
B. elevated potassium and chloride levels.
C. increased MCV and elevated triglyceride levels.
D. increased urine and serum creatinine levels.
Correct Answer: C. increased MCV and elevated triglyceride levels.
Rationale:
Chronic alcohol use commonly causes:
, • Macrocytosis (increased MCV) due to impaired folate metabolism and bone marrow
effects.
• Elevated triglycerides due to altered lipid metabolism.
• Increased liver enzymes due to hepatic injury.
• A: Incorrect — alcohol use is associated with increased, not decreased, MCV.
• B: Incorrect — electrolyte abnormalities vary but are not characteristic findings.
• D: Incorrect — increased creatinine suggests renal dysfunction, not typical alcohol-
related laboratory changes.
4. A new patient arrives at the office for treatment for depression. The patient reports taking
simvastatin (Zocor) and lisinopril (Zestril). When selecting an antidepressant, the psychiatric-
mental health nurse practitioner eliminates fluoxetine hydrochloride (Prozac), based on the
knowledge that the combination can lead to increased plasma levels of the statin, resulting in
an increased risk of muscle damage and rhabdomyolysis. What is the nurse practitioner's
rationale?
A. Both medications are CYP450 3A4 inhibitors.
B. Both medications are CYP450 3A4 substrates.
C. One medication is a CYP450 3A4 substrate and one is a CYP450 3A4 inducer.
D. One medication is a CYP450 3A4 substrate and one is a CYP450 3A4 inhibitor.
Correct Answer: D. One medication is a CYP450 3A4 substrate and one is a CYP450 3A4
inhibitor.
Rationale:
Simvastatin is metabolized by CYP450 3A4. Fluoxetine can inhibit CYP450 enzymes, increasing
simvastatin blood levels and increasing the risk of:
• Myopathy
• Muscle toxicity
• Rhabdomyolysis
• A: Incorrect — simvastatin is not an inhibitor.
• B: Incorrect — the interaction involves inhibition, not both being substrates.
• C: Incorrect — fluoxetine is not a CYP450 inducer.
