Care of Patients with Sexually
Transmitted Disease
Sexually Transmitted Diseases (STDs)
• Caused by infectious organisms that have
been passed from one person to another
through intimate contact, usually oral or
vaginal intercourse.
• Others can be transmitted by parenteral
exposure to infected blood, fecal-oral
transmission, intrauterine transmission to the
fetus, and perinatal transmission from mother
to neonate.
Syphilis
• Can become systemic and cause serious
complications and even death
• Affected nearly 25% of the U.S. population
before penicillin (1940s)
• Primary syphilis ulcer—a chancre
• Secondary syphilis—develops 6 weeks to 6
months after onset
• Early and late latent syphilis
• Tertiary syphilis
Palmar and Plantar Secondary Syphilis
Assessment
• Obtain history of lesions or rash.
• Question penicillin allergy.
• Wear gloves when performing physical
assessment.
• Obtain specimens.
• Send for Venereal Disease Research
Laboratory (VDRL) serum test.
Drug Therapy
• IM benzathine penicillin G
• Jarisch-Herxheimer reaction may follow
antibiotic therapy for syphilis; caused by a
rapid release of products from the disruption
of the organism cells:
– Symptoms—generalized aches, pain at the
injection site, vasodilation and hypotension,
increase in temperature
– Symptomatic treatment
Nursing Management
• Reinforce information about cause of
infection, treatment, side effects, possible
complications of untreated or incompletely
treated disease, and the need for follow-up
care.
• All sexual partners must be adequately
treated as soon as possible.
Nursing Management (Cont’d)
• Urge the patient to adhere to the treatment
regimen and sexual abstinence until treatment
is completed.
Genital Herpes
• Acute, recurring, incurable viral disease
• Assessment—patient history, physical
examination, and viral culture
• Treatment—symptomatic with goals to
decrease discomfort, promote healing without
secondary infection, decrease viral shedding,
and prevent infection transmission
Drug Therapy
• Antiviral drugs do not cure the infection but
do decrease the severity, promote healing,
and decrease the frequency of recurrent
outbreaks while they are being used.
• Acyclovir, famciclovir, valacyclovir may be
prescribed.
Nursing Management
• Patient counseling and education about the
infection, the potential for recurrent episodes,
the correct use and possible side effects of
antiviral therapy, viral shedding even when
the patient is symptom free, and sexual
transmission
• Assessment of the patient’s psychological
responses to the diagnosis of genital herpes
Condylomata Acuminata (Genital
Warts)
• Condition that is caused by certain types of human
papillomavirus (HPV)
• HPV infection is thought to be the primary risk factor
for development of cervical cancer
• Initially single, small papillary growth that may grow
into large, cauliflower-like masses
• Goals of management—to remove the warts, treat the
symptoms, and prevent development of atypical or
dysplastic cells to cancer
Treatment Options
•
•
•
•
•
•
Gels
Creams
Cryotherapy
Podophyllin
TCA/BCA
Carbon dioxide laser
Treatment Options (Cont’d)

• Surgical removaal
• Treatment of sexual partners
Gonorrhea
• Sexually transmitted bacterial infection
• In men, dysuria and penile discharge
• In women, change in vaginal discharge,
urinary frequency, or dysuria; ascending
spread that can cause endometritis,
salpingitis, and pelvic inflammatory disease
Gonorrhea (Cont’d)
• Anal manifestation possible
• Oral manifestations related to throat infection
Gonorrhea (Cont’d)
Drug Therapy
• Ceftriaxone, or cefixime plus azithromycin
• Treatment of sexual partners
• Rarely, meningitis and endocarditis
Nursing Management
• Topics for teaching:
– Transmission and treatment
– Necessity of taking medications for the prescribed
time
– Possibility of re-infection
– Avoidance of sexual activity until the antibiotic
therapy is complete and symptoms disappear
Chlamydial Infection
• Chlamydia trachomatis is an intracellular
bacterium and the causative agent of genital
chlamydial infections.
• It invades the columnar epithelial tissues in
the reproductive tract.
• C. trachomatis is now reportable to the local
health departments in all states.
• Many women with chlamydial infections are
asymptomatic.
Interventions
• Azithromycin
• All sexual contacts should be tested and
treated, whenever possible
• Expedited partner therapy (EPT)
• Patient and partner education
Pelvic Inflammatory Disease
• Complex infectious process in which
organisms from the lower genital tract
migrate from the endocervix upward
through the uterine cavity into the
fallopian tubes.
• Resultant infections include:
– Endometritis
– Salpingitis
– Oophoritis
Pelvic Inflammatory Disease (Cont’d)
– Parametritis
– Peritonitis
– Tubal or tubo-ovarian abscess
• Rule out ectopic pregnancy and appendicitis.

be permanent depending on the total
absorbed dose
• Altered taste sensations
• Fatigue related to increased energy demands
• Inflammatory responses that cause tissue
fibrosis and scarring
Nursing Care of Patients

cope.

Hormonal Manipulation
• Some hormones make hormone-sensitive
tumors grow more rapidly.
• Some tumors actually require specific
hormones to divide. Therefore decreasing the
amount of these hormones to hormonesensitive tumors can slow the cancer growth
rate.
Side Effects of Hormone Therapy
• Androgens and antiestrogen receptor drugs
cause masculinizing effects in women.
• For men and women receiving androgens,
acne may develop, hypercalcemia is common,
and liver dysfunction may occur with
prolonged therapy.

who take estrogens, progestins, or
antiandrogen receptor drugs.
• Gynecomastia.
Gynecomastia
Photodynamic Therapy

chemical reaction triggered by different types
of laser light
• Patient teaching

after the photosensitizing drug is injected
Immunotherapy: Biological
Response Modifiers (BRMs)
• Drugs that modify the patient’s biological
responses to tumor cells
• Cytokines—enhance the immune system
• Interleukins, interferons
• Side effects—generalized and sometimes
severe inflammatory reactions, peripheral
neuropathy, skin rashes
Gene Therapy
• Experimental as a cancer treatment
• Renders tumor cells more susceptible to
damage or death by other treatments
• Injection into tumor cells, enabling the
immune system to better recognize cancer
cells as foreign and kill them
• Human leukocyte antigen (HLA)
• Cytokines, IL-2
Targeted Therapy
