1. Why is a prolapsed umbilical cord dangerous?

A. The cord may be wrapped around the baby's neck, causing strangulation.
B. The cord might pull the placenta from the uterine wall during delivery.
C. The baby's head may compress the cord, cutting off its supply of oxygen.
D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

2. Upon delivery of a baby's head, you see that the umbilical cord is wrapped around its neck. Initial treatment for this condition should include:

A. Clamping and cutting the umbilical cord.
B. Gently pulling on the cord to facilitate removal.
C. Trying to remove the cord from around the neck.
D. Keeping the cord moist and providing rapid transport.

Correct answer: C

Rationale: When encountering a situation where the umbilical cord is wrapped around a baby's neck upon delivery, the initial treatment should involve trying to remove the cord from around the neck gently. It is crucial to handle this situation delicately to avoid causing harm to the baby. Attempting to ease the cord over the baby's head without pulling or tightening can help prevent potential complications associated with cord compression. Choice A, clamping and cutting the umbilical cord, is not recommended as it can lead to abrupt deprivation of oxygen to the baby. Choice B, gently pulling on the cord, can worsen the situation by tightening the cord around the baby's neck. Choice D, keeping the cord moist and providing rapid transport, is not the immediate concern and does not address the potential risks of cord compression during delivery. Therefore, the priority is to carefully attempt to remove the cord from around the baby's neck to ensure a safe delivery.

3. A postpartum client is concerned about hair loss. The nurse explains that this is:

A. A sign of nutritional deficiency
B. A temporary condition due to hormonal changes
C. An indication of a thyroid disorder
D. A result of poor hair care during pregnancy

Correct answer: B

Rationale: Hair loss postpartum is a common temporary condition caused by hormonal changes that occur after giving birth. This condition is known as postpartum alopecia and is a normal part of the postpartum period. It is important for the nurse to reassure the client that this hair loss is temporary and usually resolves on its own without the need for medical intervention. Choice A is incorrect because postpartum hair loss is primarily due to hormonal changes rather than nutritional deficiency. Choice C is incorrect as thyroid disorder is not typically the cause of postpartum hair loss. Choice D is incorrect as poor hair care during pregnancy does not cause postpartum hair loss.

4. What should be the drop rate per minute using a drop factor of 20 drops/ml?

A. 19 drops/min
B. 23 drops/min
C. 36 drops/min
D. 46.7 drops/min

Correct answer: A

Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.

5. A 5-year-old boy was struck by a car when he ran out into the street. When you arrive at the scene and approach the child, you see him lying supine approximately 15 feet from the car. Based on the child's age and mechanism of injury, which of the following should you suspect to be his PRIMARY injury?

A. Lower leg injury
B. Head injury
C. Upper thorax injury
D. Pelvic injury

Correct answer: D

Rationale: Given the mechanism of injury and the distance the child was thrown, a primary pelvic injury should be suspected due to the high impact and force. The pelvis is a common site for significant injury in such cases, and the distance the child was thrown indicates a high-energy impact that could lead to pelvic fractures or injuries.
