Study Questions
Temperature Measurement:
A nurse is assessing a client's body temperature. Which route provides the most accurate measurement of core body temperature?
Explanation
Answer: d. Rectal Explanation: The rectal route provides the most accurate measurement of core body temperature as it reflects the temperature of blood perfusing the hypothalamus, which regulates body temperature.
a. The oral route is commonly used and provides a convenient method for temperature measurement but may be influenced by oral intake and respiratory route, making it slightly less accurate.
b. The axillary route is less invasive and easier to use, but it tends to underestimate core body temperature.
c. The temporal route provides a quick measurement but may not be as accurate as the rectal route, especially in certain populations.
A nurse is assessing a client's body temperature and obtains a reading of 102°F (38.9°C). What action should the nurse take?
Explanation
Answer: b. Document the temperature and continue monitoring. Explanation: A temperature reading of 102°F (38.9°C) indicates a fever but does not require immediate intervention unless accompanied by other significant symptoms or in certain high-risk populations. The nurse should document the temperature and continue monitoring the client's condition.
a. Administering antipyretic medication may be appropriate based on the client's symptoms and healthcare provider's orders, but it is not the immediate action for a single temperature reading of 102°F.
c. Applying cool compresses can provide comfort to the client but does not address the underlying cause of the fever.
d. Notifying the healthcare provider immediately is not necessary based solely on a temperature reading of 102°F without other significant symptoms or concerns.
A nurse is assessing a client's body temperature using a tympanic thermometer. How should the nurse position the thermometer for accurate measurement?

A nurse is assessing a client's pain and determines that the pain is neuropathic in nature. Which medication would be most appropriate for managing neuropathic pain?
Explanation
Choice A Rationale: Acetaminophen is commonly used for pain relief, but it is not specifically effective for neuropathic pain. It primarily works by reducing fever and mild pain, but it does not target nerve-related pain. Not recommended as the primary choice for neuropathic pain management.
Choice B Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that helps reduce inflammation and relieve pain. However, it is not the best choice for neuropathic pain. While it may provide some relief for general pain, it does not specifically address neuropathic pain caused by nerve damage. Not recommended as the primary choice for neuropathic pain management.
Choice C Rationale: Morphine is a potent opioid analgesic commonly used for severe pain, including cancer-related pain. However, it is not the first-line treatment for neuropathic pain. Opioids have significant side effects, including the risk of addiction, constipation, and sedation. Not the ideal choice for managing neuropathic pain due to its potential risks and lack of specificity.
Choice D Rationale: Gabapentin is an anticonvulsant medication that has been widely used for neuropathic pain management. It works by modulating calcium channels in nerve cells, reducing abnormal electrical activity and providing pain relief. Recommended for neuropathic pain, especially when other options have failed. Commonly used doses range from 300 mg to 1800 mg per day, divided into multiple doses. Side effects may include dizziness, drowsiness, and weight gain. Regular monitoring and dose adjustments are necessary.

Oscillometric (automated): Use an electronic device that measures blood pressure using oscillations in the arterial wall.
C. Normal Range: Systolic: <120 mmHg, Diastolic: <80 mmHg
D. Factors Affecting Blood Pressure:
Age: Blood pressure tends to increase with age.
Stress and anxiety: Emotional factors can temporarily elevate blood pressure.
Physical activity: Exercise or exertion can cause a temporary rise in blood pressure.
Oxygen saturation Measurement
Oxygen saturation Measurement:
Definition: Oxygen saturation measures the percentage of hemoglobin that is saturated with oxygen in arterial blood.
Equipment: A pulse oximeter is used to assess oxygen saturation, and it consists of a probe attached to a body site (finger, earlobe, forehead) and a display screen.
Procedure: Attach the probe to the selected site, ensure proper positioning and skin integrity, allow the device to read and stabilize, note the SpO2 percentage, and document the findings accurately.
Use a pulse oximeter to measure SpO2 non-invasively.
Place the sensor on a vascular bed (e.g., finger, earlobe) and ensure a proper fit.
Allow the reading to stabilize, usually within a few seconds.
Record the SpO2 level accurately.
Consider factors that can affect oxygen saturation, such as circulation and skin pigmentation.
Pain Assessment
Pain Assessment:
Pain is a subjective experience and varies among individuals.
Use a pain scale (e.g., numerical rating scale, visual analog scale) to assess pain intensity.
Ask the patient to rate their pain on a scale from 0 to 10 or use appropriate pain descriptors.
Assess the location, quality, duration, and aggravating or relieving factors of the pain.
Consider the patient's non-verbal cues, such as facial expressions and body language.
Document the pain assessment findings accurately.
Conclusion
Conclusion:
Accurate measurement of vital signs is crucial for assessing a patient's overall health status and identifying potential abnormalities.
