Unit 2: Antepartum Nursing Care Flashcards
Abstinence is
abstaining from having sexual intercourse eliminating the possibility of sperm entering a woman’s vagina. (Though other “sexual acts” may be practiced)
Advantages of abstinence are
- 100% effective
- Can eliminate the risk of STIs if there is no genitalia contact
- Abstinence during fertile periods (rhythm method) can be used, but it requires an understanding of the menstrual cycle and fertility awareness.
Disadvantages of Abstinence
Requires self-control
Risks / complications / contraindication of Abstinence
None if complete abstinence is maintained
Define Coitus Interuptus
Man withdraws penis from vagina prior to ejaculation
Advantages of Coitus Interuptus
Possible choice for monogamous couples with no other option for birth control (i.g. religious restrictions)
Disadvantages of Coitus Interuptus
- Most ineffective method of contraception
- No protection against STIs
Risks /complications / contraindications
of Coitus Interuptus
- Male partner’s control can make this an effective method
- Leakage of fluid that contains spermatozoa prior to ejaculation can be deposited in the vagina
- Risk of pregnancy
Define the calendar method
- A woman records her menstrual cycle and calculates her fertile period based on the assumption that ovulation occurs 14-day prior to menstruation.
- Viability of sperm (48-120hr) and ovum (24hr) must also be accounted.
Advantages of the Calendar Method
- Most useful when combined with basal body temperature or cervical mucus method
- Inexpensive
Disadvantages of the Calendar Method
- Not a very reliable technique
- Requires accurate record keeping
- Requires compliance with abstinence during fertile window
Risks / complications / contraindications of the Calendar Method
- Various factors can affect and change the time of ovulation and cause unpredictable menstrual cycle.
- Risk of pregnancy
Define the Basal body temperature method
Temperature can drop slightly at the time of ovulation This can be used to facilitate contraception, or be used as a natural contraceptive
Advantages of the basal body temperature method
- Inexpensive
- convenient
- no side effects
Disadvantages of the basal body temperature
- BBT reliability can be influenced by many variables that can cause inaccurate interpretation of temperature changes
- stress
- fatigue
- illness
- alcohol
- warmth/coolness of sleeping environment
Risks/ Complications / Complications of the Basal body temperature method
- Risk of pregnancy
Define the symptom based method (cervical mucus)
Fertility awareness method based on ovulation.
Ovulation occurs about 14 days prior to the next ovulation cycle. Following ovulation, the cervical mucus becomes thin and flexible under the influence of estrogen and progesterone to allow for sperm motility and viability.
The ability of the cervical mucus to stretch between the fingers is greatest during ovulation. (~1” spinnbarkeit sign)
Advantages of the cervical mucus method
- A woman can become knowledgeable in recognizing her own mucus characteristics at ovuation, and self-evaluation can be very accurate
- Self-evaluation of cervical mucus can also be diagnostically helpful in determining the start of ovulation while breastfeeding, in noting the commencement of menopause, and in planning a desired pregnancy
Disadvantages of the cervical mucus method
- Some women may be uncomfortable with thouching their genitals and mucus and therefore, will find this method objectionable.
Risks / Complications / Contraindications of the cervical mucus method
- Assessment of cervical mucus characteristics may be inaccurate if mucus is mixed with other fluids
- Risk of pregnancy
Define condoms as a contraceptive method
A thin flexible sheath worn on the penis during intercourse to prevent semen from entering the uterus
Advantages of the condom
Protects against STIs and involves the male in the birth control method
Disadvantages of the condom method
- High rate of noncompliance
- May reduce spontaneity of intercourse
- The penis must be erect to apply a condom
- If the penis is withdrawn while still erect, this can interfere with sexual intercourse
Risks / Complications / Contraindications of condoms
- Condoms can rupture or leak
- condoms have a one-time usage
- Condoms made of latex should nt be worn by those who are sensitive or allergic to latex
- Only water-soluble lubricants should be used with latex condoms to avoid condom breakage
Teaching for condoms
- A man places the condom on the erect penis, leaving an empty space at the tip for a sperm reservoir
- Following ejaculation, a man withdraws his penis from the woman’s vagina while holding the rim of the condom to prevent any semen spillage to the woman’s vulva or vaginal area
- May be used in conjunction with spermicidal gel or cream to increase effectiveness.
Define diaphram as a contraceptive
- A dome-shaped cup with a flexible rim made of latex or silicone that fits snugly over the cervix with spermicidal cream or gel place into the dome and around the rim
Teaching for diaphragm
- A female client must be fitted with a diaphragm
- A client must be refitted by the provider every 2 years, if there is a 15lb(7kg) weight change, full-term pregnancy or second-term abortion
- Requires proper insertion and removal.
- prior to coitus - inserted vaginally with spermicide on the cervical side and rim
- post coitus - the diaphragm must stay in place at least 6 hours
- Spermicide must be reapplied with each act of coitus
- A client should emply her bladder prior to insertion of the diaphragm
Advantages of the diaphragm
This barrier bethod eliminates surgery and gives a woman more control over contraception
Disadvantages of the diaphragm
- Diaphragms are inconvenient, interfere with spontaneity, and require reapplication with spermicidal gel, cream, or foam with each coitus act
- Requires a prescriiption and a visit to a provider
- Must be inserted correctly to be effective
Risks / complications / contraindications of the diaphragm
- Diaphragms not reccommended for pts who have a hx of toxic shock syndrome, or frequent, recurrent UTIs
- Increased risk of Toxic shock ( caused by bacterial infection)
- Proper hand hygiene aids in prevention of TSS, as well as removing diaphragm promptly at 6 hr folllowing coitus
- Diaphragms made of latex should not be worn by those with sensitivity or allergy to latex
Definition of combined oral contraceptive methods
Hormonal contraception containing estrogen and progestin, which acts by suppressing ovulation, thickening the cervical mucus to block semen, and altering the uterine decidua to prevent implantation.
Advantages of combined oral contraceptive methods
- Highly effective if taken correctly and consistently
- Medication can alleviate dysmenorrhea by decreasing menstrual flow and menstrual cramps
- Reduces acne
Disadvantages of combined oral contraceptives method
- Oral contraceptives do not protect against STIs
- Birth control pills can increase the risk of thromboses, breast tenderness, scant or missed menstruation, stroke, nausea, headaches, and hormone-dependent cancers
- Exacerbates conditions affected by fluid retention such as migraine, epilepsy, asthma, kidney, or heart disease
