Embryo development

Question 1 of 5

The germ layers of the embryo are: (Select all that apply.)

Correct Answer: A,B,C

Extract:

A pediatric patient with weight-based medication

Question 2 of 5

A medication is prescribed based on a pediatric patient's weight. What should the nurse consider when calculating the dosage?

A. The client's height B. The safe dosage range C. The client's age D. The client's gender

Correct Answer: B

Rationale: Pediatric medication doses are calculated based on weight (mg/kg). The nurse must ensure the dose falls within the safe dosage range to avoid under- or overdosing.

Extract:

A hospitalized child

Question 3 of 5

When a child is hospitalized, which of the following would be an example of regression?

A. The child develops new interests and hobbies B. The child starts sucking their thumb again C. The child becomes more independent in self-care activities D. The child experiences an increase in appetite

Correct Answer: B

Rationale: Regression is a return to earlier developmental behaviors due to stress, such as thumb-sucking in a hospitalized child. New interests, independence, or increased appetite are not regression.

Extract:

A client at 21 weeks of gestation, scheduled for an international flight

Question 4 of 5

A nurse is talking with a client who is at 21 weeks of gestation and is scheduled for an international flight. Which of the following instructions should the nurse include? (Select all that apply.)

A. Avoid sitting for long periods of time during the flight to prevent swelling and discomfort. B. Wear compression stockings during the flight to prevent blood clots. C. Avoid using seat belts during the flight to prevent pressure on the abdomen. D. Take frequent walks and do leg exercises during the flight to promote circulation. E. Avoid using electronic devices during the flight to reduce radiation exposure. Take a high dose of vitamin C before the flight to boost the immune system.

Correct Answer: A,B,D

Rationale: Pregnant women on long flights are at risk for swelling and deep vein thrombosis (DVT). Avoiding prolonged sitting, wearing compression stockings, and frequent walking/leg exercises reduce these risks. Seat belts should be worn low across the hips for safety, and electronic device radiation is negligible. High-dose vitamin C lacks evidence for preventing illness during flights.

Extract:

A client in labor with a tocodynamometer (TOCO) transducer

Question 5 of 5

A nurse assisting in the care of a client, places the tocodynamometer (TOCO) transducer on a client's fundus and secures it in place. The client asks the nurse to explain the purpose of the monitoring device. Which of the following responses should the nurse make?

A. This monitor gives me information related to fetal heart rate fluctuations during your labor. B. This monitor measures the intensity and frequency of your contractions so I can observe labor progress. C. This monitor allows me to observe your labor progress. By observing the pattern, I can tell how strong your contractions are. D. This monitor provides me with information related to the duration and frequency of your contractions.

Correct Answer: D

Rationale: The tocodynamometer (TOCO) measures the frequency and duration of uterine contractions but not their intensity, which requires an intrauterine pressure catheter. It does not monitor fetal heart rate.
