Nursing Elites

1. Individuals with Klinefelter syndrome produce:

• A. less estrogen than normal males.
• B. less testosterone than normal males.
• C. less adenine than normal males.
• D. less thymine than normal males.

Correct answer: B

Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY), leading to reduced production of testosterone, the primary male sex hormone. This deficiency can result in various physical and developmental characteristics associated with the syndrome. Estrogen levels may actually be relatively elevated due to the imbalance between testosterone and estrogen. Choices C and D are incorrect as adenine and thymine are nucleotide bases found in DNA and are not related to hormone production.

2. The nurse is providing care for a newborn who was delivered vaginally assisted by forceps. The nurse observes red marks on the head with swelling that does not cross the suture line. Which condition should the nurse document in the medical record?

• A. Caput succedaneum
• B. Hydrocephalus
• C. Cephalhematoma
• D. Microcephaly

Correct answer: C

Rationale: The correct answer is Cephalhematoma. Cephalhematoma is a collection of blood between the skull bone and periosteum that does not cross the suture line. It often occurs due to birth trauma, such as forceps delivery, leading to localized swelling. Caput succedaneum (Choice A) is diffuse swelling of the scalp that may cross suture lines and is typically present at birth. Hydrocephalus (Choice B) is an abnormal accumulation of cerebrospinal fluid within the brain's ventricles. Microcephaly (Choice D) is a condition characterized by a smaller than average head size and may be present at birth or develop later in infancy.

3. Twenty-year-old Jack is extremely tall and has very thick facial hair. Most of his male secondary sex characteristics are also more pronounced than men of his age. In this scenario, Jack is most likely:

• A. an XYY male.
• B. diagnosed with Klinefelter syndrome.
• C. an XXY male.
• D. diagnosed with Down syndrome.

Correct answer: A

Rationale: The correct answer is A: an XYY male. Individuals with XYY syndrome often exhibit increased height and more pronounced secondary male characteristics, such as thick facial hair. Choice B, Klinefelter syndrome (XXY), typically presents with less prominent male secondary sex characteristics due to the presence of an extra X chromosome. Choice C, XXY male, refers to Klinefelter syndrome, which does not align with the description of Jack having more pronounced male secondary sex characteristics. Choice D, Down syndrome, is caused by a trisomy of chromosome 21 and is not associated with the physical characteristics described in the scenario.

4. Which of the following is a fatal genetic neurologic disorder whose onset is in middle age?

• A. Tay-Sachs disease
• B. Duchenne muscular dystrophy
• C. Hemophilia
• D. Huntington’s disease

Correct answer: D

Rationale: Huntington's disease is a fatal genetic neurologic disorder characterized by progressive nerve cell degeneration in the brain. It typically manifests in middle age with symptoms such as involuntary movements, cognitive decline, and psychiatric disturbances. Tay-Sachs disease (Choice A) is a genetic disorder that primarily affects the nervous system in early childhood, not middle age. Duchenne muscular dystrophy (Choice B) is a genetic disorder that primarily affects muscle function and usually presents in early childhood. Hemophilia (Choice C) is a genetic disorder related to blood clotting, and its onset is not typically in middle age.

5. Which statement by the client will assist the healthcare provider in determining whether she is in true labor as opposed to false labor?

• A. I passed some thick, pink mucus when I urinated this morning.
• B. My bag of waters just broke.
• C. The contractions in my uterus are getting stronger and closer together.
• D. My baby dropped, and I have to urinate more frequently now.

Correct answer: C

Rationale: The correct answer is C. Regular, strong contractions with the presence of cervical change indicate that the woman is experiencing true labor. Choice A indicates the passing of the mucus plug, which is a sign of early labor but not definitive for true labor. Choice B, the breaking of the bag of waters, is a sign of labor but does not confirm whether it is true or false labor. Choice D, the baby dropping and increased urination frequency, suggests lightening, a sign that labor may be approaching, but it does not confirm true labor.
