Nursing Elites

1. The _____ is the inner layer of the embryo from which the lungs and digestive system develop.

• A. neural tube
• B. mesoderm
• C. endoderm
• D. umbilical cord

Correct answer: C

Rationale: The endoderm is the correct answer. It is the innermost layer of the embryo that gives rise to organs such as the lungs, digestive system, liver, and pancreas. The neural tube (Choice A) forms the brain and spinal cord, not the lungs or digestive system. Mesoderm (Choice B) develops into structures like muscles, bones, and circulatory system, not the lungs or digestive system. The umbilical cord (Choice D) serves as a connection between the embryo and the placenta, providing nutrients and oxygen, but it is not the layer from which lungs and digestive system develop.

2. A client is in the second stage of labor. Which of the following manifestations should the nurse expect?

• A. The client expels the placenta
• B. The client experiences gradual dilation of the cervix
• C. The client begins having regular contractions
• D. The client delivers the newborn

Correct answer: D

Rationale: During the second stage of labor, the cervix is fully dilated, and the client delivers the newborn. The expulsion of the placenta occurs during the third stage of labor, not the second stage. Regular contractions typically begin in the first stage of labor, not the second. Gradual dilation of the cervix occurs during the first stage of labor, specifically during the active phase.

3. Does a blastocyst gain mass only when it receives nourishment from outside?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. Always

Correct answer: A

Rationale: A blastocyst does indeed require external nourishment from the mother's body to continue developing and gaining mass. Without this external nourishment, the blastocyst would not be able to grow and develop properly. Therefore, the statement that a blastocyst gains mass only when it receives nourishment from outside is true. Choices B, C, and D are incorrect because they do not accurately reflect the dependency of a blastocyst on external nourishment for its development and growth.

4. A client in labor requests nonpharmacological pain management. Which of the following nursing actions promotes client comfort?

• A. Assisting the client into a squatting position
• B. Having the client lie in a supine position
• C. Applying fundal pressure during contractions
• D. Encouraging the client to void every 6 hours

Correct answer: A

Rationale: Assisting the client into a squatting position promotes comfort during labor. This position can help relieve pain by utilizing gravity, allowing the pelvic outlet to widen, and potentially facilitating the progress of labor. Lying in a supine position (Choice B) can hinder labor progression and increase discomfort. Applying fundal pressure (Choice C) can be inappropriate and may cause harm as it is not routinely recommended during labor. Encouraging the client to void every 6 hours (Choice D) is important for bladder management but does not directly address pain relief during labor.

5. A newborn is 24 hours old, and a healthcare provider is caring for them. Which of the following laboratory findings should the healthcare provider report to the provider?

• A. Hgb 20 g/dL
• B. Bilirubin 2 mg/dL
• C. Platelets 200,000/mm3
• D. WBC count 32,000/mm3

Correct answer: D

Rationale: The correct answer is D: WBC count 32,000/mm3. A WBC count of 32,000/mm3 is significantly elevated in a newborn and could indicate an infection, which needs immediate attention and intervention. High white blood cell counts in newborns can be concerning as they may suggest an ongoing infection or other underlying issues that require prompt medical evaluation and treatment. Choices A, B, and C are within normal ranges for a newborn and would not typically warrant immediate reporting to the provider. Hgb levels of 20 g/dL (Choice A) are high for newborns, but this is not as concerning as a significantly elevated WBC count. Bilirubin levels of 2 mg/dL (Choice B) are within normal limits for a newborn and do not indicate immediate issues. Platelet count of 200,000/mm3 (Choice C) is also within the normal range for a newborn and would not require immediate reporting.
