**NR607 Complete Exam Review: 100 Practice
Questions with Answers and Rationales
1. Pharmacodynamics describe which of the following?**
- **Answer:** Pharmacodynamics describe how the drug affects the
body.
- **Rationale:** Pharmacodynamics refers to the biochemical and
physiological effects of drugs on the body, including the mechanisms of
drug action and the relationship between drug concentration and
effect. This is distinguished from pharmacokinetics, which describes
how the body affects the drug (absorption, distribution, metabolism,
excretion).
---
**2. Which statistical test identifies a relationship between two
variables?**
- **Answer:** Pearson's r correlation
- **Rationale:** Pearson's correlation coefficient (r) measures the
strength and direction of the linear relationship between two
continuous variables. Values range from -1 (perfect negative
correlation) to +1 (perfect positive correlation), with 0 indicating no
correlation.

**3. Being loyal and keeping promises is an example of what ethical
principle?**
- **Answer:** Fidelity
- **Rationale:** Fidelity is faithfulness to one's duties, promise-
keeping, or the commitment to obligations. In healthcare, this principle

being trustworthy in the therapeutic relationship.

**4. A patient who is refusing psychiatric treatment has their case
adjudicated. The judge orders treatment over objection for the good of
the patient. This is an example of which ethical principle?**
- **Answer:** Beneficence
- **Rationale:** Beneficence is the ethical duty to act in the patient's
best interest. When a patient is unable to make decisions due to severe
mental illness, the legal system may intervene to ensure they receive
necessary treatment that would benefit them, even against their will.

,**5. The PMHNP signs an involuntary admission order for emergent
psychiatric care for a client presenting with hallucinations and
threatening self-harm. This action applies which ethical principle?**
- **Answer:** Commitment to the Healthcare Consumer
- **Rationale:** Commitment to the healthcare consumer involves
prioritizing patient safety and welfare. When a patient poses an
imminent risk of harm to self or others, the PMHNP has an ethical
obligation to initiate emergency interventions, including involuntary
hospitalization when necessary.
---
**6. What is the foundation of a therapeutic relationship with a
psychiatric patient?**
- **Answer:** Approaching professional relationships with compassion,
caring, and respect, acknowledging the dignity and worth of each
individual, and advocating to overcome negative stigmas toward
psychiatric patients.
- **Rationale:** The therapeutic relationship in psychiatric nursing is
built on trust, empathy, and mutual respect. Patients with mental
health conditions often face significant stigma, and the PMHNP's role
includes advocacy and creating a safe, non-judgmental environment.
---
, **7. The PMHNP arranges to meet with a client via weekly interactive
video sessions due to a global pandemic limiting face-to-face visits. This
is an example of which PMHNP role?**
- **Answer:** Telehealth
- **Rationale:** Telehealth utilizes telecommunication technology to
deliver healthcare services remotely. This modality has become
increasingly important for maintaining continuity of care when in-
person visits are not feasible while still providing therapeutic
interventions and medication management.
---
**8. A client presents with persistent sadness and hopelessness for the
last two months, difficulty sleeping, and decreased appetite. This is the
patient's first contact with the healthcare system about her concerns.
This is an example of which PMHNP role?**
- **Answer:** Primary Care
- **Rationale:** Primary care mental health services are often the
initial point of contact for patients presenting with mental health
concerns. The PMHNP in this role provides first-line assessment,
diagnosis, and treatment, coordinating with other healthcare providers
as needed.
