Example Questions

Example Question #1021 : Nclex

Which of the following is false regarding the respiratory system of pregnant women? 

Possible Answers:

There is increased metabolic demand for oxygen from the body

Total lung capacity decreases

The diaphragm elevates

Oxygen consumption is increased

The rib cage becomes slightly more compact

Correct answer:

The rib cage becomes slightly more compact

Explanation:

In pregnancy, the ribs start to flare (expand slightly) as the pressure from the growing fetus moves the diaphragm upwards. Many women experience this during the third trimester as the baby is at it's largest. The flaring of the ribs is assisted by maternal hormones that enable more flexibility throughout the body.

Example Question #3 : Causes And Treatments Of Ob/Gyn Conditions

Which of the following reasons does not indicate the need to induce labor?

Possible Answers:

Fetal macrosomia

Gestational hypertension

Fetal jeopardy

Postmaturity

Diabetes

Correct answer:

Fetal macrosomia

Explanation:

Induction of labor may occur for various indications: diabetes, postmaturity, hypertensive disorders or pregnancy, fetal jeopardy, or logistical factors including distance from qualified hospital or a rate of rapid birth. Induction of labor may only occur if the mother does not have cephalopelvic disproportion (CPD), the fetus has a vertex presentation with an engaged head, and the mother has a "ripened" cervic or is prepared to be "ripened". Fetal macrosomia is a concerning condition and may require intervention, but is typically not resolved by inducing labor. With fetal macrosomia, a cesarean section may be considered instead of vaginal delivery, due to the potential risks of delivering a large infant vaginally.

Example Question #4 : Causes And Treatments Of Ob/Gyn Conditions

What is the most common form of female reproductive tumor?

Possible Answers:

Endometrial adenocarcinoma

Yolk sac tumor

Uterine leiomyoma

Choriocarcinoma

Correct answer:

Uterine leiomyoma

Explanation:

The most common tumor of the female reproductive tract by far is uterine leiomyoma, also known as a uterine fibroid. Uterine fibroids are benign smooth muscle tumors that grow into the myometrium. They can often cause pain in the lower back or pain during penetration, dysmenorrhea, and menorrhagia.  

Example Question #214 : Conditions And Treatments

Sudden onset of severe abdominal pain with a unilateral adnexal mass would most likely be which of the following conditions?

Possible Answers:

Teratoma

Ovarian torsion

Polycystic ovarian syndrome

Pelvic inflammatory disease

Correct answer:

Ovarian torsion

Explanation:

While any of the conditions listed can cause abdominal or pelvic pain, the most likely cause of severe pain of sudden onset is ovarian torsion. This is an emergency condition which can result in loss of the affected ovary if not treated within four hours. 

Example Question #1023 : Nclex

Clear-cell adenocarcinoma of the vagina is strongly linked to pre-birth exposure to what medication?

Possible Answers:

Thalidomide

Acetaminophen 

Diethylstilbestrol (DES)

Clomiphene

Correct answer:

Diethylstilbestrol (DES)

Explanation:

Diethylstilbestrol (DES), a medication used from 1940 to 1971 to reduce the risk of miscarriage, resulted in the later development of clear-cell adenocarcinoma in many of the unborn children of these pregnancies. 

Example Question #221 : Conditions And Treatments

A patient enters the labor and delivery unit. She is having a singleton birth and the baby is showing minimal variability on the fetal monitor. Interventions may include all but __________.

Possible Answers:

suggesting that the patient walk with a portable monitor

giving the patient a 500mL IV fluid bolus

placing the patient on a non-rebreather mask

placing the patient flat on her back

contacting the provider

Correct answer:

placing the patient flat on her back

Explanation:

Increasing fluid and oxygen administration may increase the overall oxygenation of the fetus and result in greater variability in heart rate. It is advisable to change the position of the patient, however, a supine position is not compatible with pregnancy. Contacting the provider is an acceptable intervention given concern for fetal well-being.

Example Question #1022 : Nclex

What is the most common cause of mucopurulent cervicitis? 

Possible Answers:

Herpes simplex virus

Neisseria gonorrhea

Chlamydia trachomatis

Human papillomavirus

Correct answer:

Chlamydia trachomatis

Explanation:

The most common cause of mucopurulent cervicitis is chlamydia trachomatis, followed by neisseria gonorrhea. Human papillomavirus, while it is associated with increased risk of development of cervical cancer, does not cause mucopurulent cervicitis, nor does herpes simplex.

Example Question #1023 : Nclex

Which of the following conditions can result in temporary masculinization of a pregnant woman which resolves after delivery?

Possible Answers:

Placental aromatase deficiency

Chloasma

Growth hormone deficieny

Polycystic ovarian syndrome

Correct answer:

Placental aromatase deficiency

Explanation:

Placental aromatase deficiency is a condition that prevents testosterone from being aromatized into estrogen during pregnancy. This results in a temporary masculinization of the mother that does not continue past delivery. Neither chloasma nor growth hormone deficiency result in masculinization, and masculinizing symptoms of polycystic ovarian syndrome often improve during pregnancy, rather than getting worse. 

Example Question #1024 : Nclex

Which of the following conditions presents as vulvar pruritus and pain with porcelain-white vaginovulvular atrophy?

Possible Answers:

Bacterial vaginosis

Lichen sclerosus

Herpes simplex

Contact vulvitis

Correct answer:

Lichen sclerosus

Explanation:

Lichen sclerosus is a condition that presents as vulvar pruritus and pain with porcelain-white vaginovulvular atrophy. It is most common in post-menopausal women, though it does occur on occasion in younger women and girls. While all of the other conditions listed can cause puritis and pain, none of them are associated with frank atrophy.   

Example Question #1025 : Nclex

All of the following are part of the Amsel criteria for bacterial vaginosis except __________.

Possible Answers:

Vaginal pH > 4.5 

All of there are part of the Amsel criteria for bacterial vaginosis

Thin gray or white vaginal discharge

A positive "whiff" test on addition of potassium hydroxide to the vaginal discharge

Correct answer:

All of there are part of the Amsel criteria for bacterial vaginosis

Explanation:

The Amsel criteria for bacterial vaginosis are as follows: clue cells seen on microscopic examination, a positive "whiff" test on addition of potassium hydroxide to the vaginal discharge, a vaginal pH > 4.5, and thin gray or white vaginal discharge.
