Critical Care Nursing Cardiac Questions Questions
Question 1 of 5
A nurse is caring for an elderly man recently admitted to the ICU following a stroke. She assesses his cognitive function using a new cognitive assessment test she learned about in a recent article in a nursing journal. She then brings a cup of water and a straw to the patient because she observes that his lips are dry. Later, she has the patient sit in a wheelchair and takes him to have some blood tests performed. He objects at first, saying that he can walk on his own, but the nurse explains that it is hospital policy to use the wheelchair. That evening, she recognizes signs of an imminent stroke in the patient and immediately pages the physician. Which action taken by the nurse is the best example of evidence-based practice?
Correct Answer: C
Rationale: The correct answer is C: Recognizing signs of an imminent stroke and paging the physician. This action exemplifies evidence-based practice as it involves timely identification of a critical medical condition based on clinical assessment and prompt communication with the physician for further intervention. This aligns with the principles of evidence-based practice, which emphasize the integration of best available evidence with clinical expertise and patient values. The other choices are incorrect: A: Giving the patient a cup of water - While providing hydration is important for patient care, it does not demonstrate evidence-based practice in this scenario. B: Transferring the patient in a wheelchair - Although using a wheelchair may be hospital policy, it does not directly relate to evidence-based practice in this context. D: Using the cognitive assessment test - While assessing cognitive function is essential, it does not directly address the immediate medical needs of the patient as recognizing signs of an imminent stroke does.
Question 2 of 5
The nurse wishes to enhance sleep cycles in her critically ill patient. Research has shown that which nursing action improves sleep in critically ill patients?
Correct Answer: D
Rationale: The correct answer is D: Adequate pain control. Pain can significantly disrupt sleep in critically ill patients. By ensuring adequate pain control, the nurse can help improve the patient's ability to rest and sleep. This intervention targets a key factor affecting sleep cycles in critically ill patients. Repositioning every 2 hours (A) may help prevent pressure ulcers but does not directly address sleep improvement. Hypnotic medications (B) may have adverse effects and are not recommended as a first-line intervention. Five-minute back effleurage (C) may provide temporary relaxation but is not as effective as adequate pain control in improving sleep quality.
Question 3 of 5
Which of the following is (are) official journal(s) of the A merican Association of Critical-Care Nurses? (Select all that apply.)
Correct Answer: A
Rationale: Step-by-step rationale: 1. The American Association of Critical-Care Nurses (AACN) publishes the American Journal of Critical Care (AJCC). 2. The AJCC is a peer-reviewed journal that covers critical care nursing practice, research, and education. 3. The content in AJCC aligns with AACN's mission and standards for critical care nursing. 4. Hence, AJCC is an official journal of AACN. Summary of other choices: - B: Critical Care Clinics of North America - Not an official journal of AACN. - C: Critical Care Nurse - Not an official journal of AACN. - D: Critical Care Nursing Quarterly - Not an official journal of AACN.
Question 4 of 5
Noninvasive diagnostic procedures used to determine kidney function include which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Kidney, ureter, bladder (KUB) x-ray. This procedure is noninvasive and commonly used to assess kidney function by visualizing the size, shape, and position of the kidneys. Renal ultrasound is also noninvasive and can provide detailed images of the kidneys. However, MRI and IVP are more invasive procedures that involve the use of contrast agents and are not typically used solely for diagnostic purposes to assess kidney function. Overall, KUB x-ray and renal ultrasound are the preferred noninvasive options for evaluating kidney function.
Question 5 of 5
In determining the glomerular filtration rate (GFR) or creatinine clearance, a 24-hour urine is obtained. If a reliable 24-hour urine collection is not possible,
Correct Answer: D
Rationale: The correct answer is D because when a reliable 24-hour urine collection is not possible, a standardized formula can be used to estimate GFR. The Cockcroft-Gault equation or the Modification of Diet in Renal Disease (MDRD) equation are commonly used formulas to estimate GFR based on serum creatinine levels, age, gender, and race. These formulas provide a reasonable estimation of kidney function in the absence of a 24-hour urine collection. Choice A is incorrect because there are alternative methods available to estimate GFR. Choice B is incorrect because BUN alone is not sufficient to accurately determine renal function. Choice C is incorrect because an elevated BUN/creatinine ratio is not a direct measure of GFR and may be influenced by factors other than kidney function, such as hydration status or liver function.
