1. When both of the alleles for a trait, such as hair color, are the same, the person is said to be _____ for that trait.

Correct answer: C

Rationale: A person is homozygous for a trait when they have two identical alleles for that trait. In this case, both alleles are the same, indicating a homozygous genotype. Choice A, 'monozygous,' is incorrect as it refers to identical twins originating from a single fertilized egg. Choice B, 'dizygous,' is also incorrect as it refers to fraternal twins or individuals that develop from two separate fertilized eggs. Choice D, 'hemizygous,' is incorrect because it describes a genetic condition where only one allele is present in a diploid organism, typically related to genes on the sex chromosomes.

2. During the client’s initial prenatal visit, which of the following would indicate a need for further assessment?

Correct answer: A

Rationale: A history of diabetes for 6 years indicates a pre-existing medical condition that can significantly impact both the mother and the developing fetus during pregnancy. This necessitates further assessment and monitoring to manage potential complications. Regular exercise (Choice B) is generally beneficial during pregnancy and does not raise immediate concerns. Occasional use of over-the-counter pain relievers (Choice C) is common and does not necessarily indicate a need for further assessment during the initial visit. Maternal age of 30 years (Choice D) falls within the normal range for childbearing and is not a standalone factor requiring immediate further assessment.

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

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.

4. What is the most critical action in caring for the newborn immediately after birth?

Correct answer: A

Rationale: The most critical action in caring for the newborn immediately after birth is keeping the airway clear. This is essential to ensure that the newborn can breathe effectively and prevent any respiratory distress. Fostering parent-newborn attachment, although important, is not the most critical action immediately after birth. Drying the newborn and wrapping the infant in a blanket is important for temperature regulation but is not as critical as maintaining a clear airway. Administering eye drops and vitamin K is typically done later and is not the most critical action immediately after birth.

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

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.
