Nursing Elites

1. _____ is a type of estrogen, prescribed in the 1940s and 1950s to pregnant women, that is said to have caused testicular, vaginal, and cervical cancer in some offspring.

• A. Androsterone
• B. Adiponectin
• C. Progestin
• D. Diethylstilbestrol

Correct answer: D

Rationale: Diethylstilbestrol (DES) is a synthetic estrogen that was prescribed to pregnant women in the 1940s and 1950s to prevent miscarriages. However, it was later discovered that DES exposure in utero could lead to health issues in offspring, including an increased risk of testicular, vaginal, and cervical cancer. Choice A, Androsterone, is a steroid hormone produced in small amounts in humans and unlikely to be associated with the adverse effects described. Choice B, Adiponectin, is a protein hormone that plays a role in regulating glucose levels and fatty acid breakdown, not related to the adverse effects mentioned. Choice C, Progestin, is a synthetic form of progesterone used in birth control and hormone therapy, not linked to the specific health concerns associated with DES exposure.

2. A client has active genital herpes simplex virus type 2. Which of the following medications should the nurse plan to administer?

• A. Metronidazole
• B. Penicillin
• C. Acyclovir
• D. Gentamicin

Correct answer: C

Rationale: Acyclovir is the antiviral medication specifically used to treat herpes simplex virus infections, including genital herpes caused by herpes simplex virus type 2. Metronidazole (Choice A) is an antibiotic used for different types of infections, but not for viral infections like herpes. Penicillin (Choice B) is an antibiotic effective against bacterial infections, not viruses like herpes. Gentamicin (Choice D) is an antibiotic mainly used to treat bacterial infections, not viral infections like herpes.

3. What causes Down's syndrome?

• A. Alcohol abuse by the mother at the time of conception.
• B. Sex-linked chromosomal abnormalities.
• C. An extra chromosome on the 21st pair.
• D. Drug abuse by the mother during pregnancy.

Correct answer: C

Rationale: Down's syndrome, also known as trisomy 21, is caused by the presence of an extra chromosome on the 21st pair. Choice A is incorrect as alcohol abuse is not the cause of Down's syndrome. Choice B is incorrect because Down's syndrome is not related to sex-linked chromosomal abnormalities. Choice D is also incorrect as drug abuse by the mother during pregnancy is not the cause of Down's syndrome.

4. Which of the following statements is true about Tay-Sachs disease?

• A. It is most commonly found among children in Jewish families of Eastern European background.
• B. Children who have this disease suffer from excessive production of mucus in the lungs and pancreas.
• C. It is most commonly found among children in Asian American families.
• D. Children who have this disease suffer from muscular dystrophy characterized by a weakening of the muscles.

Correct answer: A

Rationale: The correct answer is A. Tay-Sachs disease is most commonly found among Jewish families of Eastern European descent. It is a fatal genetic disorder that affects the nervous system. Choice B is incorrect because Tay-Sachs disease does not involve excessive mucus production in the lungs and pancreas. Choice C is incorrect as it states that Tay-Sachs disease is most commonly found among Asian American families, which is inaccurate. Choice D is also incorrect because Tay-Sachs disease does not cause muscular dystrophy characterized by weakening of the muscles.

5. A newborn is being assessed following a forceps-assisted birth. Which of the following clinical manifestations should the nurse identify as a complication of the birth method?

• A. Hypoglycemia
• B. Polycythemia
• C. Facial Palsy
• D. Bronchopulmonary dysplasia

Correct answer: C

Rationale: Facial palsy is a known complication of forceps-assisted birth. During forceps delivery, pressure applied to the facial nerve can result in facial palsy. The newborn may present with weakness or paralysis of the facial muscles on one side. Hypoglycemia (Choice A) is not directly related to forceps-assisted birth. Polycythemia (Choice B) is a condition characterized by an increased number of red blood cells and is not typically associated with forceps delivery. Bronchopulmonary dysplasia (Choice D) is a lung condition that primarily affects premature infants who require mechanical ventilation and prolonged oxygen therapy, not a direct outcome of forceps-assisted birth.
