Nursing Elites

1. Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):

• A. zygote.
• B. gonadotrope.
• C. embryo.
• D. chromaffin.

Correct answer: A

Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.

2. A client has active genital herpes simplex virus type 2. Which of the following medications should the nurse plan to administer?

• A. Metronidazole
• B. Penicillin
• C. Acyclovir
• D. Gentamicin

Correct answer: C

Rationale: Acyclovir is the antiviral medication specifically used to treat herpes simplex virus infections, including genital herpes caused by herpes simplex virus type 2. Metronidazole (Choice A) is an antibiotic used for different types of infections, but not for viral infections like herpes. Penicillin (Choice B) is an antibiotic effective against bacterial infections, not viruses like herpes. Gentamicin (Choice D) is an antibiotic mainly used to treat bacterial infections, not viral infections like herpes.

3. The embryo and fetus develop within a protective _______ in the uterus.

• A. amniotic sac
• B. umbilical cord
• C. neural tube
• D. embryonic disk

Correct answer: A

Rationale: The correct answer is A, the amniotic sac. The amniotic sac is a fluid-filled structure that surrounds and protects the developing embryo and fetus in the uterus. It provides a cushion against external pressure, allows for movement and growth, and helps maintain a stable environment for the developing fetus. Choices B, C, and D are incorrect. The umbilical cord connects the fetus to the placenta and serves as a conduit for nutrients and waste; the neural tube is a structure that forms the central nervous system in early embryonic development; and the embryonic disk is a structure that forms during gastrulation, one of the early stages of embryonic development.

4. What is the primary rationale for thoroughly drying the infant immediately after birth?

• A. Stimulates crying and lung expansion.
• B. Removes maternal blood from the skin surface.
• C. Reduces heat loss from evaporation.
• D. Increases blood supply to the hands and feet.

Correct answer: C

Rationale: The primary rationale for thoroughly drying the infant immediately after birth is to reduce heat loss from evaporation. This helps maintain the infant's body temperature and prevent hypothermia. Choice A (Stimulates crying and lung expansion) is incorrect because drying the infant is not primarily done to stimulate crying but rather to prevent heat loss. Choice B (Removes maternal blood from the skin surface) is incorrect as the main reason is to prevent heat loss, not to remove maternal blood. Choice D (Increases blood supply to the hands and feet) is also incorrect as drying the infant is not intended to increase blood supply but rather to regulate body temperature.

5. A client is receiving an epidural block with an opioid analgesic. The nurse should monitor for which of the following findings as an adverse effect of the medication?

• A. Hypotension
• B. Polyuria
• C. Bilateral crackles
• D. Hyperglycemia

Correct answer: C

Rationale: The correct answer is C: Bilateral crackles. Bilateral crackles indicate respiratory complications, which can occur as an adverse effect of an epidural block with opioid analgesics. Hypotension (Choice A) is a common side effect of epidural opioids but is not typically monitored via crackles. Polyuria (Choice B) is excessive urination and is not directly associated with epidural blocks. Hyperglycemia (Choice D) is high blood sugar levels and is not a typical adverse effect of epidural opioids.
