3. Black Box Warning antipsychotic drugs have an increased mortality in - verified answer1. Serious
or fatal hepatic failure has occurred with use of Depakote ER. In addition, life-threatening
pancreatitis has been reported. Depakote is also linked to increased fetal risk (neural tube defects,
major malformations, IQ)
2. fatal dermatologic reactions—toxic epidermal necrolysis & SJS—have been reported. Also w/
carbamazepine aplastic anemia and agranulocytosis have occurred
3. Elderly patients with dementia-related psychosis
1. BPH is a common condition that develops in more than
2. BPH is a nonmalignant prostate enlargement cells
3. Overgrowth of epithelial cells causes - verified answer1. 50% of men by age 60 years and 90% by
age 85 years.
2. caused by excessive growth of epithelial (glandular) cells and smooth muscle
3. mechanical obstruction of the urethra, whereas overgrowth of smooth muscle causes dynamic
obstruction of the urethra.
1. Drugs for ED fall into two major groups: oral and nonoral. The oral agents include
2. The nonoral agents include
3. Four PDE-5 inhibitors are available:
4. MOA of PDE-5 inhibitors causes selective inhibition of PDE-5. By doing so,
5. Benefits of PDE-5 inhibitors can - verified answer1. PDE-5 inhibitors—are by far the most common
treatments for ED.
2. include papaverine plus phentolamine & alprostadil
3. sildenafil, tadalafil, vardenafil, and avanafil. All are considered first-line therapy for ED.
4. it increases and preserves cGMP levels in the penis, thereby making the erection harder and
longer lasting.
5. help a wide range of patients, including those with diabetes, spinal cord injury, and transurethral
prostate resection as well as ED of no known physical cause
,1. List other rare but serious SE of Conventional antipsychotics
2. Black Box Warning-Antipsychotic Drugs - verified answer1. Neuroleptic malignant syndrome (lead
pipe" rigidity, sudden high fever >41°C), Orthostatic hypotension-not rare, Seizures, Agranulocytosis
2. When used to tx dementia-related psychosis in elderly pts, all FGAs & SGAs approx double the
rate of mortality. Most deaths result from heart-related events (e.g., heart failure, sudden death) or
pneumonia
1. List the Adverse effects for PDE-5 inhibitors
2. What are the most COMMON adverse effects - verified answer1. - Hypotension-especially when
combined with alpha blockers
- Priapism: (painful erection lasting more than 6 hours)
- Nonarteritic ischemic optic neuropathy: resulting in irreversible blurring or loss of vision. The cause
is blockage of blood flow to the optic nerve
- Sudden hearing loss.
2. headache, flushing, and dyspepsia, may also cause nasal congestion, diarrhea, rash, and dizziness.
About 3% of patients experience mild transient visual disturbances (a blue tinge to vision, increased
sensitivity to light, blurring)
1. OCD is characterized by
2. An obsession is defined as a
3. Treatment; (blank) is probably more important in OCD than in any other psychiatric disorder
4. DOC for OCD
5. Therapy of an initial episode - verified answer1. persistent obsessions and compulsions that cause
marked distress, consume at least 1 hour a day, and significantly interfere with daily living
2. recurrent, persistent thought, impulse (need for cleanliness or orderliness); whereas a compulsion
a ritualized behavior or mental act in response to the obsession
3. Behavioral therapy
4. SSRIs are first-line drugs for OCD
5. should continue for at least 1 year; withdrawal should be done slowly; relapse is common
1. Preferred administration route of alprostadil and why
Because of the inconvenient method of dosing, these drugs are second-line agents for ED. - verified
answer1. Alprostadil has the same chemical structure as prostaglandin E1, which causes vasodilation
When injected into the Intracavernous penile tissue it causes relaxation of smooth muscle (arterial,
venous, and trabecular), causing a rapid inflow of arterial blood.
, The blood fills the vascular sinusoidal spaces of the corpus cavernosum, resulting in an erection
1. Tx goals for AD
2. No single drug is more effective than the others, so
3. The current gold standard of treatment for cognitive symptoms - verified answer1. slow loss of
memory and cognition and prolong independent function (delay symptom progression)
2. selection should be based on tolerability, ease of use, and cost
3. includes pharmacologic management with a cholinesterase (ChE) inhibitor and an NMDA
antagonist.
6. Minimizing Adverse Effects of Estrogen:
• Nausea is common early in treatment. Advise patients that this adverse effect - verified answer6.
diminishes with time. In the meantime, avoidance of cooking odors and warm, stuffy environments
may help. Dry foods and raw fruits and vegetables help as well as Guided imagery with muscle
relaxation, yoga, and music therapy
• Menopausal HT with estrogen alone increases the risk for endometrial carcinoma. Adding a
progestin lowers this risk to the pretreatment level.
• Adverse effects similar to those caused by OCs (abnormal vaginal bleeding, hypertension, benign
hepatic adenoma, reduced glucose tolerance)
A patient diagnosed with Alzheimer's disease has decided to stop treatment. The NP has educated
