Nursing Elites

1. 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.

2. 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.

3. What nursing diagnosis is the most appropriate for a woman experiencing severe preeclampsia?

• A. Risk for injury to mother and fetus, related to central nervous system (CNS) irritability.
• B. Risk for altered gas exchange.
• C. Risk for deficient fluid volume, related to increased sodium retention secondary to the administration of magnesium sulfate.
• D. Risk for increased cardiac output, related to the use of antihypertensive drugs.

Correct answer: A

Rationale: The most appropriate nursing diagnosis for a woman experiencing severe preeclampsia is 'Risk for injury to mother and fetus, related to central nervous system (CNS) irritability.' Severe preeclampsia poses a significant risk of injury to both the mother and the fetus due to complications such as seizures, stroke, and placental abruption. 'Risk for altered gas exchange' is not the priority diagnosis as pulmonary edema is more common in severe preeclampsia. 'Risk for deficient fluid volume' is incorrect as sodium retention in severe preeclampsia often leads to fluid overload. 'Risk for increased cardiac output' is also incorrect as antihypertensive drugs are used to reduce cardiac output in this condition.

4. A client at 37 weeks gestation presents to labor and delivery with contractions every two minutes. The nurse observes several shallow small vesicles on her pubis, labia, and perineum. The nurse should recognize the client is exhibiting symptoms of which condition?

• A. Genital Warts
• B. Syphilis
• C. Herpes Simplex Virus
• D. German Measles

Correct answer: C

Rationale: The correct answer is C: Herpes Simplex Virus (HSV). HSV can present with small vesicles on the genital area, and it is a concern during labor due to the risk of transmission to the newborn. Genital warts (Choice A) are caused by the human papillomavirus (HPV) and typically present as flesh-colored growths, not vesicles. Syphilis (Choice B) manifests as painless sores and can have systemic effects but does not typically present with vesicles. German measles (Choice D), also known as Rubella, is a viral illness characterized by a red rash, fever, and lymphadenopathy, not vesicles.

5. Which of the following illnesses causes degeneration of the central nervous system?

• A. Tay-Sachs disease
• B. Cystic fibrosis
• C. Turner syndrome
• D. Klinefelter syndrome

Correct answer: A

Rationale: Tay-Sachs disease is a genetic disorder that causes a progressive degeneration of the central nervous system, particularly in infants. Choice B, Cystic fibrosis, is a genetic disorder that primarily affects the lungs and digestive system, not the central nervous system. Choices C and D, Turner syndrome and Klinefelter syndrome, are chromosomal disorders that do not directly involve degeneration of the central nervous system.
