1. Monozygotic (MZ) twins are known as fraternal twins.

• A. TRUE
• B. FALSE
• C. Possibly
• D. Never

Correct answer: B

Rationale: The correct answer is B: 'FALSE.' Monozygotic (MZ) twins are identical twins, not fraternal. Fraternal twins are dizygotic (DZ). The statement in the question is incorrect as MZ twins are genetically identical, while fraternal twins actually refer to dizygotic twins who develop from two separate fertilized eggs. Therefore, monozygotic twins are not known as fraternal twins, making option B the correct choice. Options A, C, and D are incorrect as they do not accurately describe the relationship between monozygotic and fraternal twins.

2. How many pairs of autosomes does a human zygote contain?

• A. 46
• B. 44
• C. 23
• D. 22

Correct answer: D

Rationale: A human zygote contains 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes. Therefore, the correct answer is 22. Choices A, B, and C are incorrect because they do not accurately represent the number of autosomes in a human zygote. Option A (46) represents the total number of chromosomes in a human zygote, not the number of autosomes. Option B (44) is incorrect as it does not account for the correct number of autosomes. Option C (23) is inaccurate since it represents the total number of chromosomes in a human gamete, not the number of autosomes in a zygote.

3. A healthcare provider is assessing a newborn upon admission to the nursery. Which of the following should the provider expect?

• A. Bulging Fontanels
• B. Nasal Flaring
• C. Length from head to heel of 40 cm (15.7 in)
• D. Chest circumference 2 cm (0.8 in) smaller than the head circumference

Correct answer: D

Rationale: Upon admission to the nursery, a healthcare provider should expect the newborn's chest circumference to be slightly smaller than the head circumference. This is a normal finding in newborns due to their physiological development. Bulging fontanels (Choice A) can indicate increased intracranial pressure, which is abnormal. Nasal flaring (Choice B) is a sign of respiratory distress and is also an abnormal finding. While a length from head to heel of 40 cm (15.7 in) (Choice C) falls within the normal range for newborns, it is not a specific expectation upon admission to the nursery. Therefore, the correct expectation for a newborn upon admission is for the chest circumference to be slightly smaller than the head circumference.

4. Four clients at full term present to the labor and delivery unit at the same time. Which client should a nurse assess first?

• A. Multipara with contractions occurring every three minutes
• B. Multipara scheduled for non-stress test and biophysical profile
• C. Primipara with vaginal show and leaking membranes
• D. Primipara with burning on urination and urinary frequency

Correct answer: C

Rationale: A primipara with vaginal show and leaking membranes requires immediate assessment as she may be in active labor or at risk of infection. The vaginal show and leaking membranes suggest potential rupture of membranes and the start of labor. Assessing her first ensures prompt management and monitoring. The other options, while important, do not indicate immediate or emergent needs. Contractions every three minutes in a multipara can be managed with ongoing monitoring; non-stress tests and biophysical profiles can be scheduled and are not acute needs. Burning on urination and urinary frequency in a primipara may indicate a urinary tract infection, which is important but not as urgent as assessing for active labor or rupture of membranes.

5. Which of the following statements is a symptom of cystic fibrosis in children?

• A. Cystic fibrosis leads to uncontrollable muscle movements and personality changes.
• B. Cystic fibrosis leads to the excessive production of thick mucus that clogs the pancreas and lungs.
• C. Cystic fibrosis causes red blood cells to clump together, obstructing small blood vessels and decreasing the oxygen supply.
• D. Cystic fibrosis causes the central nervous system to degenerate, resulting in death.

Correct answer: B

Rationale: The correct answer is B. Cystic fibrosis is a genetic disorder that causes the body to produce thick, sticky mucus. This mucus can clog the airways in the lungs and obstruct the pancreas, leading to severe respiratory and digestive problems. Choice A is incorrect because uncontrollable muscle movements and personality changes are not typical symptoms of cystic fibrosis. Choice C is incorrect because cystic fibrosis does not directly cause red blood cells to clump together and obstruct small blood vessels. Choice D is incorrect because cystic fibrosis primarily affects the respiratory and digestive systems, not the central nervous system.
