1. A healthcare professional is planning to obtain the vital signs of a 2-year-old child who is experiencing diarrhea and who might have a right ear infection. Which of the following routes should the healthcare professional use to obtain the temperature?
- A. Temporal
- B. Oral
- C. Rectal
- D. Axillary
Correct answer: C
Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.
2. After successful resuscitation, a client is given propranolol and transferred to the Intensive Coronary Care Unit (ICCU). On admission, magnesium sulfate 4 grams IV in 250 ml D5W at one gram/hour. Which assessment findings require immediate intervention by the nurse?
- A. Dark amber urine draining via an indwelling catheter at a rate of 40 ml per hour
- B. Serum calcium of 9.0 mg/dl (2.2 mmol/L SI) and magnesium of 1.8 mg/dl or Eq/L (0.74 mmol/L SI)
- C. Sinus rhythm at 72 beats/minute and peripheral blood pressure of 99/62
- D. Respiratory rate of 10 breaths per minute
Correct answer: D
Rationale: The correct answer is D. A low respiratory rate of 10 breaths per minute is indicative of possible magnesium toxicity, which can be a serious condition requiring immediate intervention. It is a critical finding that needs prompt attention to prevent further complications. The other options are not as urgent: A - dark amber urine may indicate dehydration but does not require immediate intervention, B - serum calcium and magnesium levels are within normal limits, C - sinus rhythm and blood pressure values are also within normal range and do not require immediate action.
3. Which nursing intervention is most appropriate for managing delirium in an elderly patient?
- A. Keeping the room brightly lit
- B. Administering sedatives as needed
- C. Encouraging family presence
- D. Restricting fluids
Correct answer: C
Rationale: Encouraging family presence is the most appropriate intervention for managing delirium in elderly patients. This intervention provides orientation, reassurance, and comfort, which can help reduce confusion and anxiety, thus aiding in managing delirium. Keeping the room brightly lit (Choice A) may worsen delirium as it can disrupt the patient's sleep-wake cycle. Administering sedatives (Choice B) should be avoided unless absolutely necessary due to the risk of worsening delirium. Restricting fluids (Choice D) is not a recommended intervention for managing delirium, as hydration is important for overall patient well-being.
4. The healthcare professional is developing a care plan for a client with depression. What should be included in the plan?
- A. Regular physical activity
- B. Scheduled sleep patterns
- C. Social interaction with family and friends
- D. All of the above
Correct answer: D
Rationale: A comprehensive care plan for a client with depression should include multiple components to address various aspects of health. Regular physical activity can help improve mood and overall well-being. Scheduled sleep patterns are essential as sleep disturbances are common in depression and can worsen symptoms. Social interaction with family and friends provides emotional support and reduces feelings of isolation. Therefore, including all these aspects in the care plan can help support the client's recovery. Choice D, 'All of the above,' is the correct answer because all the options are important components of a holistic care plan for depression. Choices A, B, and C are incorrect because each of these elements plays a crucial role in managing depression.
5. A parent tells the nurse in the emergency department, 'My 3-year-old has had a fever for several days and has been vomiting.' After instituting ordered measures to reduce the fever, what nursing action is most important?
- A. Preventing shivering
- B. Restricting oral fluids
- C. Measuring output hourly
- D. Taking vital signs hourly
Correct answer: A
Rationale: Preventing shivering is crucial in this scenario as it can increase body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat through muscle activity, which can elevate the body temperature. Restricting oral fluids (choice B) is inappropriate as maintaining hydration is vital, especially in cases of fever and vomiting. Measuring output hourly (choice C) and taking vital signs hourly (choice D) are important nursing actions but not the most critical in this case where preventing shivering takes precedence.
