What is the CDC recommended medication for the treatment of chlamydia?
A. Penicillin
Penicillin is not a correct option, as it is not effective against chlamydia. Penicillin is an antibiotic that works by inhibiting the cell wall synthesis of bacteria. However, chlamydia is an intracellular bacterium that does not have a cell wall and is resistant to penicillin.
B. Acyclovir
Acyclovir is not a correct option, as it is not effective against chlamydia. Acyclovir is an antiviral drug that works by inhibiting the DNA synthesis of viruses. However, chlamydia is a bacterium, not a virus, and is not affected by acyclovir².
C. Doxycycline
Doxycycline is the correct option, as it is one of the recommended medications for the treatment of chlamydia. Doxycycline is a tetracycline antibiotic that works by inhibiting the protein synthesis of bacteria. It can penetrate the cells and kill chlamydia by interfering with its growth and reproduction. The CDC recommends a 7-day course of doxycycline (100 mg orally twice a day) for the treatment of uncomplicated chlamydia infection.
D. Podofilox
Podofilox is not a correct option, as it is not effective against chlamydia. Podofilox is a topical medication that works by destroying the tissue of genital warts caused by human papillomavirus (HPV). However, chlamydia is a different infection that does not cause genital warts and is not treated by podofilox.

What is the best nursing intervention for a pregnant woman in her third trimester who complains of feeling faint, dizzy, and agitated while her vital signs are being assessed?
A. Have the patient stand up and retake her blood pressure.
This is not a good intervention, as it may worsen the symptoms of faintness, dizziness, and agitation. Standing up can cause a sudden drop in blood pressure (orthostatic hypotension), which can reduce the blood flow to the brain and the fetus. This can cause lightheadedness, blurred vision, and loss of consciousness in the woman, as well as fetal distress or hypoxia.
B. Have the patient lie supine for 5 minutes and recheck her blood pressure on both arms.
This is not a good intervention, as it may also worsen the symptoms of faintness, dizziness, and agitation. Lying supine can cause compression of the inferior vena cava (a large vein that returns blood to the heart) by the gravid uterus, which can reduce the cardiac output (the amount of blood pumped by the heart) and the blood pressure. This can cause nausea, sweating, and visual disturbances in the woman, as well as fetal distress or hypoxia.
C. Have the patient sit down and hold her arm in a dependent position.
This is not a good intervention, as it may not improve the symptoms of faintness, dizziness, and agitation. Sitting down and holding the arm in a dependent position can lower the blood pressure in the arm, but not in the rest of the body. This can cause inaccurate readings of the blood pressure and delay the detection of hypotension or hypertension. This can also cause discomfort and pain in the arm due to impaired circulation.
D. Have the patient turn to her left side and recheck her blood pressure in 5 minutes.
This is the best intervention, as it can relieve the symptoms of faintness, dizziness, and agitation by improving the blood flow to the brain and the fetus. Turning to the left side can reduce the pressure of the uterus on the inferior vena cava and increase the cardiac output and the blood pressure. This can also optimize the placental perfusion (the blood flow to the placenta) and the fetal oxygenation.

What is the main reason why a woman who is older than 35 years may have difficulty achieving pregnancy?
A. She has used contraceptives for an extended time.
This is not the main reason, as the use of contraceptives for an extended time does not necessarily affect the fertility of a woman. Most contraceptives are reversible and do not cause permanent damage to the reproductive system. However, some contraceptives may take longer to wear off than others, and some may have side effects that can interfere with ovulation or implantation.
B. Her ovaries may be affected by the aging process.
This is the main reason, as the aging process can affect the ovaries and the quality and quantity of the eggs. As a woman ages, her ovarian reserve (the number of eggs in the ovaries) declines, and the eggs become more prone to chromosomal abnormalities. This can reduce the chances of conception and increase the risk of miscarriage or birth defects.
C. Prepregnancy medical attention is lacking.
This is not the main reason, as prepregnancy medical attention is not a prerequisite for achieving pregnancy. However, prepregnancy medical attention can be beneficial for a woman who is older than 35 years, as it can help identify and manage any existing or potential health problems that may affect the pregnancy, such as diabetes, hypertension, or thyroid disorders.
D. Personal risk behaviors influence fertility.
This is not the main reason, as personal risk behaviors are not specific to a woman who is older than 35 years. Personal risk behaviors are factors that can negatively affect the fertility of any woman, regardless of age. Some examples of personal risk behaviors are smoking, drinking, using drugs, having multiple sexual partners, or having sexually transmitted infections.

What is the most dangerous effect on the fetus of a mother who smokes cigarettes while pregnant?
A. Genetic changes and anomalies
Genetic changes and anomalies are not the most dangerous effect, as they are rare and not directly caused by smoking. Smoking can increase the risk of some birth defects, such as cleft lip and cleft palate, but these are not genetic changes and can be corrected by surgery. Smoking can also cause chromosomal abnormalities in the eggs, but these usually result in miscarriage or stillbirth, not live births.
B. Intrauterine growth restriction
Maternal smoking is a significant risk factor for intrauterine growth restriction (IUGR). Nicotine and carbon monoxide from cigarettes reduce oxygen supply to the fetus, leading to lower birth weights and smaller body lengths.
C. Fetal addiction to the substance inhaled
Fetal addiction to the substance inhaled is not the most dangerous effect, as it is not permanent and can be treated by medication and supportive care. Smoking can expose the fetus to nicotine, carbon monoxide, and other harmful chemicals, which can cross the placenta and affect the fetal brain and nervous system. Smoking can also cause withdrawal symptoms in the newborn, such as irritability, tremors, and difficulty feeding.
D. Extensive central nervous system damage
Although prenatal exposure to smoking can affect neurodevelopment and is associated with behavioral issues, extensive central nervous system damage is not the most immediate or dangerous effect. The most critical concern remains intrauterine growth restriction.
