Nursing Elites

1. What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?

• A. This test will confirm fetal lung maturity.
• B. This test will determine the adequacy of placental perfusion.
• C. This test will detect fetal infection.
• D. This test will predict maternal readiness for labor.

Correct answer: B

Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.

2. 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.

3. Chromosomes are _____ structures found in cells.

• A. rod-shaped
• B. circular
• C. cone-shaped
• D. octagonal

Correct answer: A

Rationale: Chromosomes are rod-shaped structures that carry genetic information in the form of DNA. They are typically seen as elongated structures when visualized under a microscope. Choice B, circular, is incorrect as chromosomes do not have a circular shape; they are linear. Choice C, cone-shaped, is not accurate as chromosomes do not resemble cones in any way. Choice D, octagonal, is also incorrect as chromosomes do not have an octagonal appearance. Therefore, the correct answer is A, rod-shaped, which accurately describes the shape of chromosomes.

4. The _________ is the hollow organ within females in which the embryo and fetus develop.

• A. placenta
• B. ovum
• C. uterus
• D. amniotic sac

Correct answer: C

Rationale: The correct answer is C: uterus. The uterus is the organ where the embryo implants and the fetus develops during pregnancy. The placenta (choice A) is an organ that develops during pregnancy and provides nutrients and oxygen to the fetus, but it is not the organ where the embryo and fetus physically develop. The ovum (choice B) is the female reproductive cell or egg that is fertilized by the sperm to form an embryo, but it is not the organ where the embryo and fetus develop. The amniotic sac (choice D) is a membrane filled with amniotic fluid that surrounds and protects the fetus, but it is not the organ where the embryo and fetus physically develop.

5. What is the structure of deoxyribonucleic acid (DNA)?

• A. single spiral
• B. double helix
• C. sphere
• D. cube

Correct answer: B

Rationale: The correct answer is B: double helix. DNA is structured as a double helix, resembling a twisted ladder made up of two strands of nucleotides. Choice A, single spiral, is incorrect as DNA is not a single spiral structure. Choice C, sphere, is incorrect as DNA does not form a spherical shape. Choice D, cube, is incorrect as DNA does not have a cubic structure. Understanding the double helix structure of DNA is essential as it allows for the storage and transmission of genetic information in living organisms.
