Introduction to Critical Care Nursing 8th Edition Questions
Question 1 of 5
The nurse understands that medication absorption is affected by the administration route. Which route for medications has the fastest absorption rate?
Correct Answer: B
Rationale: The correct answer is B: Intravenous (IV) injection. IV injection delivers medications directly into the bloodstream, bypassing the digestive system for immediate absorption. This route ensures the fastest onset of action as the medication is rapidly distributed throughout the body. Cream applied to the skin (A) undergoes slower absorption through the skin layers. Enteric-coated capsules (C) are designed to dissolve in the intestines, delaying absorption. Subcutaneous injection (D) involves slower absorption compared to IV due to the medication being injected into the fatty tissue under the skin.
Question 2 of 5
Which flow sheet provides the health care provider with information on an ongoing record of fluid loss?
Correct Answer: D
Rationale: The correct answer is D, the Intake & Output (I&O) graphic sheet, as it provides a comprehensive record of fluid loss by documenting all fluids taken in and excreted by the patient. This is crucial for monitoring hydration status and detecting any imbalances. The Critical care flow sheet (A) focuses on critical care parameters, the Vital signs graphic sheet (B) records vital signs, and the Health assessment flow sheet (C) documents patient assessments. These choices do not specifically track fluid loss like the I&O graphic sheet does.
Question 3 of 5
Before administering a prescribed electrolyte supplement, the nurse reviews a client's electrolyte panel: What should the nurse do next?
Correct Answer: D
Rationale: The correct answer is D. Holding potassium chloride (KCl) and calling the healthcare provider (HCP) is crucial because administering electrolytes without proper assessment can be dangerous. If the electrolyte panel shows abnormal levels, especially for potassium, the nurse must seek guidance from the healthcare provider to prevent potential harm. Re-checking the client's basic metabolic panel (BMP) (choice A) may not provide specific information about the electrolyte imbalance. Administering calcium carbonate (choice B) may not address the specific electrolyte imbalance revealed in the panel. Administering potassium chloride (KCl) (choice C) without further assessment and guidance could worsen the imbalance.
Question 4 of 5
When auscultating a client9s abdomen, how long should the nurse listen before concluding the bowel sounds are absent?
Correct Answer: B
Rationale: The correct answer is B: 5 minutes. This is because the nurse should listen for a minimum of 5 minutes to accurately determine if bowel sounds are absent. Bowel sounds may be irregular and taking the time to listen for a longer period increases the chances of detecting any sounds. Listening for only 1 minute (choice A) may not provide a comprehensive assessment. Listening for 10 minutes (choice C) or 15 minutes (choice D) is unnecessary and may lead to unnecessary delays in patient care.
Question 5 of 5
The proper use of the principles of body mechanics:
Correct Answer: C
Rationale: Step 1: Body mechanics involve using proper posture and movements to prevent injury. Step 2: By applying body mechanics, both the client and nurse can avoid strains and injuries. Step 3: The primary goal of using body mechanics is to prevent harm to both parties involved. Step 4: Choice C correctly states that body mechanics aim to prevent injury to both the client and nurse. Summary: Choice A is incorrect as it only focuses on protecting the client. Choice B is incorrect as it only focuses on protecting the nurse. Choice D is incorrect as the main goal of body mechanics is not related to legal action but rather injury prevention for both parties.
