Nursing Elites

1. A client is 4 hours postpartum and is experiencing hypovolemic shock. Which of the following actions should the nurse take?

• A. Administer indomethacin
• B. Insert a second 22-gauge IV catheter.
• C. Insert an indwelling urinary catheter.
• D. Administer oxygen at 4L/min via nasal cannula.

Correct answer: D

Rationale: In hypovolemic shock, there is decreased oxygen delivery to tissues. Administering oxygen at 4L/min via nasal cannula can help improve oxygenation and support tissue perfusion. Indomethacin (Choice A) is a nonsteroidal anti-inflammatory drug and is not indicated in the management of hypovolemic shock. Inserting a second 22-gauge IV catheter (Choice B) may be necessary for fluid resuscitation, but oxygen administration takes precedence. Inserting an indwelling urinary catheter (Choice C) may be considered for monitoring urinary output, but it is not the priority action in managing hypovolemic shock.

2. The healthcare provider is preparing to administer phytonadione (vitamin K) to a newborn. Which statement made by the parents indicates understanding why the healthcare provider is administering this medication?

• A. Improve insufficient dietary intake
• B. Stimulate the immune system
• C. Help an immature liver
• D. Prevent hemorrhagic disorders

Correct answer: D

Rationale: The correct answer is D because phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease due to their low levels of vitamin K, which is essential for blood clotting. Choice A is incorrect as vitamin K administration is not related to improving dietary intake. Choice B is incorrect as vitamin K doesn't stimulate the immune system. Choice C is incorrect as vitamin K is not given to help an immature liver, but rather to prevent hemorrhagic disorders.

3. 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.

4. What term is used to describe each member of a pair of genes?

• A. allele
• B. zygote
• C. autosome
• D. node

Correct answer: A

Rationale: The correct answer is 'allele.' An allele refers to one of two or more versions of a gene located at the same position on a chromosome. In genetics, alleles are responsible for variations in inherited traits. Choice B, 'zygote,' is incorrect as a zygote is a fertilized egg cell formed by the fusion of two gametes. Choice C, 'autosome,' is incorrect as autosomes are non-sex chromosomes that determine an individual's genetic traits excluding sex-linked characteristics. Choice D, 'node,' is incorrect as it does not relate to the concept of genes or genetic inheritance.

5. After meiosis, each new cell nucleus contains _____ chromosomes.

• A. 46
• B. 35
• C. 23
• D. 12

Correct answer: C

Rationale: After meiosis, each resulting cell contains 23 chromosomes. Meiosis is a process that involves two sequential divisions resulting in four daughter cells, each with half the number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes (diploid), and after meiosis, the resulting cells (sperm or ova) have 23 chromosomes (haploid). Choice A (46 chromosomes) is incorrect because this is the number of chromosomes in a human diploid cell before meiosis. Choices B (35 chromosomes) and D (12 chromosomes) are incorrect as they do not represent the correct number of chromosomes after meiosis in human cells.
