Nursing Elites

1. 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.

2. A nurse is teaching about clomiphene citrate to a client who is experiencing infertility. Which of the following adverse effects should the nurse include?

• A. Tinnitus
• B. Urinary Frequency
• C. Breast Tenderness
• D. Chills

Correct answer: C

Rationale: The correct answer is C: 'Breast Tenderness.' Clomiphene citrate is known to cause breast tenderness as a common side effect due to its hormonal effects on the body. Tinnitus (choice A), which is a ringing in the ears, is not typically associated with clomiphene citrate. Urinary frequency (choice B) is not a common adverse effect of this medication. Chills (choice D) are also not commonly linked to clomiphene citrate use.

3. Which of the following conditions is considered a multifactorial problem?

• A. Cystic fibrosis
• B. Down syndrome
• C. Diabetes mellitus
• D. XYY syndrome

Correct answer: C

Rationale: The correct answer is 'Diabetes mellitus' because it is a multifactorial disease, influenced by both genetic predisposition and environmental factors. Cystic fibrosis (choice A) is primarily a genetic disorder caused by mutations in the CFTR gene. Down syndrome (choice B) is due to an extra copy of chromosome 21. XYY syndrome (choice D) is a genetic condition where males have an extra Y chromosome. These conditions are not considered multifactorial as their origins are primarily genetic.

4. 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.

5. Which of the following pairs of bases is present in the rungs of the ladder-like structure of deoxyribonucleic acid (DNA)?

• A. Cytosine with guanine.
• B. Rhodamine with biotin.
• C. Diaminopurine with ribozyme.
• D. Serine with tyrosine.

Correct answer: A

Rationale: The correct answer is A: Cytosine with guanine. In the DNA double helix, cytosine always pairs with guanine forming a base pair, and adenine pairs with thymine. These complementary base pairs form the rungs of the ladder-like structure of DNA. Choice B, Rhodamine with biotin, is incorrect as they are not base pairs found in DNA. Choice D, Serine with tyrosine, is incorrect as they are amino acids, not DNA bases. Choice C, Diaminopurine with ribozyme, is also incorrect as ribozyme is an enzyme, not a base, and diaminopurine is not one of the standard bases found in DNA.
