The clock-drawing test (CDT) has become a standard cognitive screening tool around the world. Like all cognitive screening tests, it is designed to detect early brain changes to determine if a person may be experiencing dementia. Which of the following statements most accurately depicts the usefulness of this test?
A. The CDT is affected by level of education and can be used alone for diagnostic purposes or for assessing the severity of cognitive impairment.
While the CDT is somewhat affected by education, it should not be used alone for diagnostic purposes because it is a screening tool, not a definitive test.
B. The CDT serves as an IQ test as well as a test of cognitive functioning.
The CDT does not measure IQ; it is designed to assess multiple domains of cognitive function including executive functioning, visuospatial abilities, and planning.
C. The CDT is easy to administer in a short time, and it assesses multiple domains of cognitive functioning.
The CDT is quick to administer, non-invasive, and provides assessment across multiple cognitive domains, making it valuable for early detection of cognitive impairment.
D. The CDT is an accurate predictor of focal brain degeneration.
The CDT does not specifically predict focal brain degeneration; it is a general screening tool rather than a neuroimaging substitute.

A 39-year-old Cambodian man presents to the PMHNP for an evaluation following an event that he refers to as "Khayal." Which culture-bound syndrome should the PMHNP include in the differential diagnosis?
A. Fright, which results in symptoms of depression
Fright syndromes typically involve transient anxiety and sadness but do not include the physical manifestations associated with Khayal.
B. Weakness of the nervous system that results in mood and somatic symptoms
Weakness of the nervous system, such as neurasthenia, is associated with chronic fatigue and somatic complaints but does not reflect the acute episodic presentation of Khayal.
C. A wind attack, similar to a panic attack, that results in tinnitus and neck soreness
Khayal is a Cambodian culture-bound syndrome characterized by a wind attack or sudden anxiety episode with physical symptoms, including tinnitus, palpitations, and neck soreness. It resembles a panic attack culturally contextualized.
D. Thinking too much, resulting in interpersonal and social difficulties
Excessive rumination or “thinking too much” is associated with some African or Caribbean syndromes but does not describe Khayal.

A 42-year-old woman recently diagnosed with rheumatoid arthritis asks the nurse practitioner about disease-modifying antirheumatic drugs (DMARDs). Which of the following statements about DMARDs is INCORRECT?
A. DMARDs target the underlying disease.
DMARDs act on the underlying inflammatory process in rheumatoid arthritis, modifying disease progression.
B. DMARDs limit joint damage and improve function.
DMARDs slow or prevent joint damage and improve long-term functional outcomes.
C. DMARDs include different classes of medications and are available orally, via subcutaneous injection, or via IV infusion.
DMARDs are a heterogeneous group, including traditional and biologic agents, administered orally, subcutaneously, or intravenously.
D. Patients can begin to experience symptom improvement 3 weeks after DMARD initiation.
Symptom improvement is typically delayed and may take 6–12 weeks or longer after starting DMARD therapy; expecting improvement in 3 weeks is inaccurate.

A 22-year-old woman diagnosed with bipolar disorder missed her last two appointments with the PMHNP after she was started on lithium (Eskalith). Her mother brought her to a third appointment. The patient was excited to see the PMHNP, as evidenced by her rapid rate of speech and discussion about the book she was writing. The patient went on to say that God had spoken directly to her and given her a message that only she could give to the world. She said she hadn’t been able to sleep for at least 1 week because she had been so busy working on this book, but she felt “absolutely incredible” despite her lack of sleep. Both the patient and the mother insist she has not stopped taking her medication. The PMHNP orders laboratory studies, including a lithium level. Which level of lithium will be subtherapeutic and indicate a need for an increased dose?
A. 5 mEq/L
A lithium level of 5 mEq/L is critically high and would indicate severe toxicity, not subtherapeutic dosing.
B. 0.5 mEq/L
A lithium level of 0.5 mEq/L is at the low end or below the therapeutic range for acute mania (0.8–1.2 mEq/L), suggesting subtherapeutic dosing and a need for an increased dose.
C. 1.2 mEq/L
A lithium level of 1.2 mEq/L is within the therapeutic range for acute mania and would not indicate underdosing.
D. 15 mEq/L
A lithium level of 15 mEq/L is lethally toxic and requires immediate medical intervention, not dose escalation.
