A nurse on a pediatric unit is assigned to care for a child with Reye syndrome. Which of the following is the most serious clinical manifestation for which the nurse should monitor?
- A. Anaphylaxis
- B. Cerebral edema
- C. Impaired coagulation
- D. Hypervolemia
Correct Answer: B
Rationale: The correct answer is B: Cerebral edema. In Reye syndrome, cerebral edema is the most serious manifestation due to increased intracranial pressure, potentially leading to brain damage or death. Anaphylaxis (A) is not typically associated with Reye syndrome. Impaired coagulation (C) can occur but is not as immediately life-threatening as cerebral edema. Hypervolemia (D) is a possible complication but not as critical as cerebral edema in Reye syndrome.

Which of the following are probable signs, strongly indicating pregnancy?
- A. The presence of fetal heart sounds is a positive sign of pregnancy; quickening is a presumptive sign of pregnancy.
- B. These are presumptive signs. They may indicate pregnancy or they may be caused by other conditions, such as disease processes.
- C. Hegar’s sign is a softening of the lower uterine segment, and Chadwick's sign is the bluish or purplish color of the cervix as a result of the increased blood supply and increased estrogen. Ballottement occurs when the cervix is tapped by an examiner's finger and the fetus floats upward in the amniotic fluid and then falls downward.
- D. These are presumptive signs that might indicate pregnancy, but they might be caused by other conditions, such as disease processes.
Correct Answer: C
Rationale: The correct answer is C because Hegar's sign and Chadwick's sign are considered probable signs of pregnancy. Hegar's sign indicates softening of the lower uterine segment, a physiological change that typically occurs in pregnancy. Chadwick's sign refers to the bluish or purplish color of the cervix due to increased blood supply and estrogen levels in pregnancy. These signs are more specific to pregnancy compared to presumptive signs like quickening, which can be caused by other conditions. Ballottement is a technique used to assess fetal movement and position, not a sign indicating pregnancy certainty. Therefore, choices A, B, and D are incorrect as they refer to presumptive signs or signs that could be caused by conditions other than pregnancy.
A nurse is caring for a 4-year-old child diagnosed with leukemia who is admitted with myelosuppression.
- A. "Provide a diet high in carbohydrates."'
- B. "Monitor rectal temperature every 4 hr."'
- C. "Use lemon or glycerin swabs for oral care."'
- D. "Inspect the skin daily for lesions."'
Correct Answer: D
Rationale: The correct answer is D: "Inspect the skin daily for lesions." This is important because myelosuppression can lead to decreased platelets, increasing the risk of skin lesions and bleeding. Monitoring the skin daily can help detect any lesions early and prevent complications.
A: Providing a high-carbohydrate diet is not directly related to managing myelosuppression.
B: Monitoring rectal temperature is important but not directly related to skin lesion detection.
C: Using lemon or glycerin swabs for oral care is important for mucositis, not skin lesions.
A woman enters the birthing center in active labor. She tells the nurse that her membranes ruptured 26 hours ago. The nurse immediately takes the client's vital signs. Which is the rationale for the nurse's actions?
- A. Pulse rates rise the longer the membranes are ruptured
- B. Respiratory rates decrease due to lack of fluid in the uterus
- C. Prolonged rupture of membranes can lead to transient hypertension
- D. Infection is a complication of prolonged rupture of membranes
Correct Answer: D
Rationale: The correct answer is D. When the membranes rupture, it increases the risk of infection as it provides a direct pathway for bacteria to enter the uterus. Taking vital signs is crucial to monitor for signs of infection such as fever, tachycardia, and hypotension. Elevated temperature and increased heart rate can indicate an infection. Choice A is incorrect because pulse rate may not necessarily rise with prolonged rupture of membranes. Choice B is also incorrect as respiratory rates are not directly affected by ruptured membranes. Choice C is incorrect as prolonged rupture can lead to infection rather than transient hypertension.
A client in active labor receives a regional anesthetic. Which is the main purpose of regional anesthetics?
- A. To relieve pain by decreasing the client's level of consciousness
- B. To provide general loss of sensation by blocking sensory nerves to an area
- C. To provide pain relief by blocking descending impulses from the central nervous system
- D. To relieve pain by decreasing the perception of pain leading to the pain centers in the brain
Correct Answer: B
Rationale: The correct answer is B: To provide general loss of sensation by blocking sensory nerves to an area. Regional anesthetics work by blocking specific nerve pathways in a targeted area, leading to loss of sensation while maintaining consciousness. This is ideal for laboring clients as it allows pain relief without affecting consciousness or motor function. Choice A is incorrect as regional anesthetics do not aim to decrease consciousness. Choice C is incorrect as regional anesthetics block sensory nerves locally, not descending impulses. Choice D is incorrect as the goal is to block sensation locally, not perception in the brain.
A nurse is caring for an adolescent with inadequate weight gain.
- A. "Identify food preferences high in complex carbohydrates."'
- B. "Identify food preferences high in saturated and unsaturated fats."'
- C. "Identify food preferences high in calcium and protein."'
- D. "Identify food preferences high in calories."'
Correct Answer: C
Rationale: The correct answer is C: "Identify food preferences high in calcium and protein." Inadequate weight gain in adolescents can be due to lack of essential nutrients like calcium and protein for growth and development. Calcium is crucial for bone health, while protein is essential for muscle development. Both are important for overall growth. Choices A and D focus on carbohydrates and calories, which are important but not the primary nutrients needed for weight gain in this scenario. Choice B suggests high intake of saturated and unsaturated fats, which can be detrimental to overall health if consumed in excess. Therefore, identifying food preferences high in calcium and protein is the most appropriate choice to address inadequate weight gain in the adolescent.
