Sexually Transmitted Infections

The 14 things this section of the textbook says that you are most likely to be asked about — quoted word for word, not retold. Then 3 practice questions with the reasoning.

Key points

  1. STI transmission and severity

    A sexually transmitted infection (STI) may develop after transmission of bodily fluids from an infected individual to a sexual partner.
  2. Safe sex risk reduction

    Safe sex practices, such as limiting one’s number of sexual partners or using appropriate protection (e.g., condoms), can decrease the risk for contracting STIs.
  3. Young adult STI burden

    People aged 15 to 24 years account for approximately 50 percent of all new cases.
  4. Asymptomatic transmission concern

    However, these numbers may be skewed due to asymptomatic individuals unknowingly transmitting infections to their sexual partners.
  5. Chlamydia and gonorrhea spread

    These bacterial STIs can be spread through all kinds of sexual contact, including vaginal, anal, and oral sex, and the sharing of sex toys.
  6. Chlamydia and gonorrhea symptoms

    Clinical manifestations of chlamydia and gonorrhea in women often mimic those of a urinary tract infection (UTI), such as foul-smelling vaginal discharge, painful urination, increased urinary frequency, itching, or burning of the vagina, and a dull ache or pain in the lower abdomen.
  7. Pelvic inflammatory disease risk

    As many as 15% of untreated women will develop pelvic inflammatory disease (PID) (Jennings Kryko, 2023).
  8. Testing co-occurring infections

    Typically, patients with a suspected STI are tested and treated for both chlamydia and gonorrhea at the same time because they often occur together and cause similar symptoms.
  9. Herpes lifelong course

    Herpes virus infection is a lifelong condition, and the frequency and severity of outbreaks will vary depending on the person and health status.
  10. HPV cancer risk

    The most severe types of HPV can cause cancers of the cervix, vagina, or anus.
  11. HPV screening importance

    Because even asymptomatic infections can eventually cause cancer, it is important for sexually active individuals to be tested for HPV frequently.
  12. Syphilis tertiary stage

    The later stage of syphilis, also called the tertiary stage, is systemic and life-threatening, and is characterized by neurological dysfunction.
  13. Nursing STI history

    The first step in caring for patients at risk for or recently diagnosed with an STI is obtaining a complete health and sexual history.
  14. Stigma and nursing care

    There is a stigma associated with STIs that can negatively affect the mental health of those affected, so nurses must be aware of this stigma and treat patients without judgment.

Terms to know

sexually transmitted infection (STI)
A sexually transmitted infection (STI) may develop after transmission of bodily fluids from an infected individual to a sexual partner.
Chlamydia trachomatis
Chlamydia trachomatis, commonly known as chlamydia, is a bacterium that is spread through infected bodily fluids, including vaginal fluid and semen, and is transmitted orally and rectally.
Herpes simplex virus (HSV)
Herpes simplex virus (HSV) causes a viral infection that can be classified into two different types: herpes simplex type 1 (HSV-1) and herpes simplex type 2 (HSV-2).
genital vesicle
HSV-1, known as oral herpes, causes cold sores on the mouth and lips and HSV-2 (“genital herpes”) results in a type of sore called a genital vesicle, or a painful fluid-filled lesion on the genitals.
Syphilis
Syphilis is a bacterial STI caused by Treponema pallidum.
chancre
The first clinical sign of a syphilis infection is the presence of a chancre, a painless sore that develops where the organism entered the body.

Every question here, with the answer

  1. At 1400, a hospitalized patient reports painful urination and foul-smelling vaginal discharge. The nurse is documenting the assessment and planned next action. Which entry is most appropriate?

    1. Symptoms attributed to chlamydia; plan to request treatment without further diagnostic testing.
    2. Findings consistent with a UTI; plan to limit further evaluation to urinary infection.
    3. Symptoms suggest a possible STI; plan to notify the care team and request further testing and treatment as needed.
    4. Possible STI symptoms identified; plan to defer evaluation to outpatient follow-up because most STIs are treated there.

    Answer: Symptoms suggest a possible STI; plan to notify the care team and request further testing and treatment as needed.

    In the hospital, suspected STI findings should prompt care-team notification and a request for appropriate testing and treatment. These symptoms can resemble a UTI, so limiting evaluation to urinary infection or attributing them specifically to chlamydia is not supported by the findings alone. The availability of outpatient treatment does not justify postponing evaluation during hospitalization.

  2. At a 1600 follow-up after STI treatment, a patient reports improved but persistent symptoms, distress about STI-related stigma, and uncertainty about prevention and where to obtain further care. Which entries appropriately reflect the nursing evaluation? Select all that apply.

    1. Symptoms have improved but remain present; continue evaluating for resolution or progression.
    2. Patient has unanswered prevention questions and needs help identifying resources; further education and resource identification are needed.
    3. Prevention education complete because the patient has received medical treatment.
    4. Patient reports stigma-related distress; psychological care needs further evaluation.
    5. Treatment successful; infection eradicated based on the patient's report of symptom improvement.

    Answer: Symptoms have improved but remain present; continue evaluating for resolution or progression., Patient has unanswered prevention questions and needs help identifying resources; further education and resource identification are needed., Patient reports stigma-related distress; psychological care needs further evaluation.

    STI evaluation includes physical and psychological care, patient education, and resource identification. Persistent symptoms, stigma-related distress, and unanswered questions support documenting ongoing needs in these areas. Symptom improvement alone does not establish eradication, and receiving medical treatment does not demonstrate that education is complete.

  3. At a 1000 follow-up visit, a patient with diagnosed HSV reports that the sores have healed and says, "That means the infection is gone." The nurse provides follow-up teaching. Which entry appropriately documents the teaching needed?

    1. Explained that the infection can be considered resolved once sores and flu-like symptoms are absent.
    2. Explained that HSV is lifelong and that periods without sores do not mean the infection has ended.
    3. Explained that an antibody test is needed to determine whether healing eliminated HSV.
    4. Explained that a swab of a future sore is needed before determining whether HSV persists between outbreaks.

    Answer: Explained that HSV is lifelong and that periods without sores do not mean the infection has ended.

    HSV is lifelong, so a period without sores does not establish that the infection has ended. Antibody testing indicates previous exposure, not whether healing eliminated HSV. A sore swab can help establish an uncertain diagnosis, but a future swab is not needed before teaching a patient with diagnosed HSV about its lifelong nature.
