1. The nurse is preparing the teaching plan for a group of parents about risks to toddlers. The nurse plans to explain proper communication in the event of accidental poisoning. The nurse should plan to tell the parents to first state what substance was ingested and then what information should be the priority for the parents to communicate?
- A. The parents' name and telephone number
- B. The currency of the immunization and allergy history of the child
- C. The estimated time of the accidental poisoning and a confirmation that the parents will bring the containers of the ingested substance
- D. The affected child's age and weight
Correct answer: D
Rationale: In the event of accidental poisoning, it is crucial to know the child's age and weight to determine the appropriate treatment. This information helps healthcare providers calculate the correct dosage of antidotes or medications needed based on the child's size and age. The child's age and weight play a significant role in managing accidental poisoning cases. Therefore, this information should be a priority for parents to communicate in such emergencies. Choices A, B, and C are not as critical as the child's age and weight when it comes to immediate treatment decisions for accidental poisoning.
2. Select the tactile sensation that is accurately paired with its description or procedure for testing.
- A. Fine motor coordination: The use of the fingers
- B. Stereognosis: Equal hearing in both ears
- C. Two-point discrimination: The nurse gently pricks the patient's skin
- D. Gross motor function: The use of the lower limbs
Correct answer: C
Rationale: The correct answer is C: Two-point discrimination: The nurse gently pricks the patient's skin. Two-point discrimination assesses the ability to discern two points touched simultaneously on the skin. Fine motor coordination (Choice A) refers to the precise movements of small muscles, not related to tactile sensation. Stereognosis (Choice B) is the ability to recognize objects by touch, not equal hearing in both ears. Gross motor function (Choice D) involves the coordination of large muscle groups, not specifically related to tactile sensation testing.
3. Assessment findings of a 3-hour-old newborn include: axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate at 42 breaths/min. Based on these findings, what action should the nurse implement?
- A. Place a pulse oximeter on the heel
- B. Swaddle the infant in a warm blanket
- C. Record the findings on the flow sheet
- D. Check the vital signs in 15 minutes
Correct answer: C
Rationale: The correct action for the nurse to take in this scenario is to record the findings on the flow sheet. The newborn's axillary temperature, heart rate, and respiratory rate are within normal limits for a 3-hour-old newborn. Therefore, there is no immediate need for intervention or further assessment. Swaddling the infant in a warm blanket, placing a pulse oximeter on the heel, or checking the vital signs in 15 minutes are not necessary actions based on the normal assessment findings presented. These actions could potentially disrupt the newborn or lead to unnecessary interventions when the baby is stable.
4. Why is randomization important in a scientific experiment?
- A. To minimize the impact of confounding variables.
- B. To eliminate bias in the assignment of subjects to groups.
- C. To contribute to the accuracy and validity of the experiment's results.
- D. To prevent systematic differences between groups.
Correct answer: B
Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.
5. What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?
- A. This test will confirm fetal lung maturity.
- B. This test will determine the adequacy of placental perfusion.
- C. This test will detect fetal infection.
- D. This test will predict maternal readiness for labor.
Correct answer: B
Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.
