You are treating a patient for his first episode of major depression. You decide to initiate citalopram
(Celexa). How much time should you allow for the medication to provide its initial therapeutic effect and
the patient to see improvement of symptoms?
8 months
4 to 6 weeks
2 weeksterm-2
2 months - CORRECT ANS:Correct answer: 4 to 6 weeks
The initial time frame for this medication to have a therapeutic effect is 4 to 6 weeks. Once the patient
begins treatment on an SSRI, and the nurse practitioner and patient agree on the regimen, patients are
expected to continue this treatment for 6 to 12 months.

What is the primary purpose of the corpus callosum?
To connect the right and left hemispheres and facilitate sensorimotor information exchange
To allow for multimodal sensory input and trigger memories
To coordinate movement of multiple muscles
To control voluntary motor movement, working memory, and behavioral cueing - CORRECT ANS:Correct
answer: To connect the right and left hemispheres and facilitate sensorimotor information exchange
The corpus callosum is a large bundle of white matter that connects the right and left hemispheres and
provides an area of sensorimotor information exchange.

,When assessing for genetic influences, the PHMNP understands which of the following about single
nucleotide polymorphisms (SNPs)?
Single-gene disorders are common
SNPs detect single-base changes during the DNA-sequencing process
To be classified as an SNP, the variant must be found in 10% of the population
SNPs are the rarest type of genetic variation among humans - CORRECT ANS:Correct answer: SNPs
detect single-base changes during the DNA-sequencing process
Single nucleotide polymorphisms detect single-base changes during DNA sequencing. SNPs are the most
common gene variant in the population and must occur in 1% of the population to be considered an
SNP.

Systemic effects of hypernatremia include which of the following?
Restlessness
Confusion
Apprehension
Lethargy - CORRECT ANS:Correct answer: Restlessness
Systemic effects of hyponatremia include confusion, apprehension, and lethargy.

Which of the following amino acids is implicated in bipolar disorder, seizures, and schizophrenia?
Aspartate
Glycine
, Glutamate
GABA - CORRECT ANS:Correct answer: Glutamate
Glutamate is also known as the universal excitatory neurotransmitter and has been connected to bipolar
disorder, seizures, mood imbalance, and schizophrenia.
Aspartate is another excitatory neurotransmitter and works in conjunction with glutamate. GABA and
glycine are inhibitory neurotransmitters.

A 29-year-old African American female was diagnosed with schizophrenia approximately three years
ago. After many trials of antipsychotics, she was finally stabilized on haloperidol during the past six
months. Three weeks ago she began exhibiting mild pseudo-Parkinson's symptoms.
Which class of medications would be most appropriate for treating these side effects?
Muscarinic 1 antagonist
Histamine 1 antagonist
Alpha 1 adrenergic agonist
Cholinesterase inhibitor - CORRECT ANS:Correct answer: Muscarinic 1 antagonist
Extrapyramidal symptoms are drug-induced side effects that affect motor functioning and muscle
movement. Extrapyramidal symptoms are associated with a deficiency of dopamine and an excess of
acetylcholine in the nigrostriatal pathway. A common type of extrapyramidal symptom is called pseudo-
Parkinson's, which presents with a shuffling gait, motor slowing, mask-like facial expression, tremors,
and muscle rigidity. Muscarinic 1 antagonist medications reduce the effects of excess acetylcholine and
relieve extrapyramidal symptoms.
