Distribution of a drug to various tissues is dependent on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: Highly perfused tissue includes all vital organs: the brain, heart, kidneys, adrenal glands, and liver. Choices 1, 2, and 3 are incorrect because the skin and adipose tissue are poorly perfused, while the skeletal muscle is better perfused.

A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?
- A. The fingers curl tightly, and the toes curl forward.
- B. The toes flare, and the big toe is dorsiflexed.
- C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
- D. The infant turns to the side that is touched.
Correct Answer: B
Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.
A multigravida pregnant woman asks the nurse when she will start to feel fetal movements. Around which week of gestation does the nurse tell the mother that fetal movements are first noticed?
- A. 16 weeks
- B. 6 weeks
- C. 8 weeks
- D. 12 weeks
Correct Answer: A
Rationale: Fetal movements (quickening) are first noticed by multigravida pregnant women at 16 to 20 weeks of gestation and gradually increase in frequency and strength. This is when the mother typically begins to feel the baby's movements. Choices B, C, and D are incorrect because fetal movements are not felt as early as 6, 8, or 12 weeks of gestation. At 6 weeks, the embryo's movements are not yet strong enough to be felt by the mother. By 8 weeks, the movements are still too subtle to be perceived. At 12 weeks, although fetal movements start, they are usually not strong enough to be felt by the mother.
A pregnant client asks a nurse about the use of noninvasive acupressure as a complementary alternative therapy to relieve nausea. The nurse provides which instruction?
- A. It is safe to try any type of complementary alternative therapy to relieve nausea
- B. The physician or nurse-midwife needs to provide a prescription for acupressure devices
- C. Devices that apply pressure alone are available over the counter
- D. Complementary alternative therapies should not be used during pregnancy
Correct Answer: C
Rationale: The correct answer is 'Devices that apply pressure alone are available over the counter.' Acupressure over the Neiguan acupuncture point can be used as a complementary alternative therapy to relieve nausea during pregnancy. It can be performed with devices that apply pressure alone, which are available over the counter. Acupressure devices that apply electrical impulses over this point require a prescription. It is not safe to try any type of complementary alternative therapy during pregnancy, as some may be harmful to the mother and fetus. Therefore, the nurse should instruct the client about the availability of over-the-counter pressure devices for acupressure, which are generally safe to use.
An Rh-negative woman with previous sensitization has delivered an Rh-positive fetus. Which of the following nursing actions should be included in the client's care plan?
- A. emotional support to help the family cope with feelings of guilt about the infant's condition
- B. administration of MICRhoGam to the woman within 72 hours of delivery
- C. administration of Rh-immune globulin to the newborn within 1 hour of delivery
- D. lab analysis of maternal Direct Coombs' test
Correct Answer: A
Rationale: In this scenario, the Rh-negative woman has been sensitized, posing a risk to any Rh-positive fetus she delivers. The most appropriate nursing action is to provide emotional support to help the family cope with the infant's condition. This includes addressing potential outcomes like death or neurological damage. Administering MICRhoGam (Choice B) to a sensitized woman is not recommended; it is only given post-abortion or ectopic pregnancy to prevent sensitization. Rh-immune globulin is not administered to the newborn (Choice C) in this case. Analyzing the maternal Direct Coombs' test (Choice D) is unnecessary; instead, an Indirect Coombs' test is used to assess sensitization. Therefore, the correct nursing action is to offer emotional support to the family, acknowledging the challenges they may face.
A nurse notes the presence of variable decelerations on the fetal heart rate monitor strip and suspects cord compression. The nurse should immediately perform which action?
- A. Insert a gloved finger into the mother's vagina to feel for cord compression
- B. Position the mother so that her hips are elevated
- C. Notify the registered nurse
- D. Perform a vaginal examination on the mother
Correct Answer: B
Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.
