Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C because maintaining hydration and nutrition until the patient dies is not always appropriate in end-of-life care, as some patients may be unable to tolerate oral intake or may be close to the end of life where artificial nutrition and hydration may not provide benefit and may even cause discomfort. Explanation: A: A is correct because terminally ill patients may indeed benefit from continuous pain management to ensure comfort. B: B is correct because hospice care is typically initiated when curative treatment is no longer effective and focuses on providing comfort and quality of life. D: D is correct because emotional support is crucial in end-of-life care to address the patient's psychological well-being and provide comfort. In summary, choice C is incorrect as it does not consider individual patient needs and preferences in end-of-life care.

Correct Answer: B

Rationale: The correct short-term goal for the client with imbalanced nutrition is choice B: Eat 50% of six small meals each day by the end of one week. This goal is specific, measurable, achievable, relevant, and time-bound (SMART). By setting a goal for the client to eat a specific amount of meals within a defined timeframe, it allows for objective monitoring of progress. This goal also addresses the client's decreased intake and aims to improve their nutritional status gradually. Choice A is incorrect as verbalizing understanding does not directly address the client's nutritional needs. Choice C is not appropriate as it does not promote independence in meal consumption. Choice D is not the best short-term goal as it focuses on the outcome of weight gain rather than the process of increasing food intake. Overall, choice B is the most appropriate short-term goal as it targets the client's specific nutritional needs and provides a clear direction for intervention.

Correct Answer: A

Rationale: The correct answer is A: The FACES scale. This scale uses facial expressions to assess pain, making it suitable for a patient who is unable to verbalize. The nurse can show the patient a series of faces depicting varying levels of pain and ask them to point to the one that best represents their pain level. This method is non-verbal and easy for patients to understand. The other choices are incorrect: B: The Pain Intensity Scale requires the patient to rate their pain on a numerical scale, which may be difficult for a non-verbal patient. C: The PQRST method is a mnemonic for assessing pain characteristics (provocation, quality, region, severity, timing), but it requires patient communication. D: The Visual Analogue Scale involves marking a point on a line to indicate pain intensity, which is not suitable for a non-verbal patient.

Correct Answer: C

Rationale: The correct answer is C: Zero reference the system daily. Zero referencing ensures accuracy and calibration of pressure monitoring system by setting the baseline pressure to zero. This is crucial to prevent inaccuracies in measurements. Choice A is important but doesn't directly address the accuracy of the monitoring system. Choice B may help in preventing errors but doesn't address the accuracy of pressure measurement. Choice D is important for alerting the nurse but doesn't directly relate to the accuracy of hemodynamic monitoring.

Correct Answer: C

Rationale: The correct answer is C because BIS and PSI monitors provide both raw EEG data and a numeric value, simplifying the interpretation of patient sedation levels. Raw EEG data offers detailed information on brain activity, while the numeric value allows for quick assessment. This simplifies the monitoring process compared to interpreting raw EEG data alone. Choice A is incorrect as BIS and PSI monitors are not restricted to heavily sedated patients. Choice B is incorrect as they are not limited to pediatric patients. Choice D is incorrect as the number of leads required does not determine the simplicity of use; it is the data interpretation that matters.
