Introduction to Critical Care Nursing 8th Edition Questions
Question 1 of 5
When performing oral care to an unconscious client, which of the following is a special consideration to prevent aspiration of fluids into the lungs?
Correct Answer: D
Rationale: The correct answer is D: Put the client in a side-lying position with the head of the bed lowered. This position helps prevent aspiration of fluids into the lungs by allowing gravity to assist in draining fluids out of the mouth and reducing the risk of them entering the airway. It also helps in preventing choking and aspiration pneumonia. A: Washing hands and observing infection control are important but do not directly address the risk of aspiration. B: Keeping the client dry with a towel does not specifically prevent aspiration and may not be effective in managing oral care for an unconscious client. C: Cleaning the mouth with oral swabs is important, but the technique does not directly address the risk of aspiration compared to positioning the client correctly.
Question 2 of 5
The medication order is chlorate hydrate 400mg. The bottle reads chlorate hydrate 0.1 g / capsules. How many capsules should be given?
Correct Answer: D
Rationale: To find the number of capsules needed, convert 400mg to grams (400mg = 0.4g). Then divide the total amount required (0.4g) by the strength of each capsule (0.1g/capsule). This results in 4 capsules needed (0.4g / 0.1g/capsule = 4 capsules). Choice D is correct as it aligns with the calculation. Choices A, B, and C are incorrect as they do not match the calculated amount required based on the medication strength and dosage.
Question 3 of 5
What action should a nurse take if a pleur-evac attached to a chest tube breaks?
Correct Answer: C
Rationale: The correct answer is C: Place the end of the tube in sterile water. This action prevents air from entering the pleural space and causing a pneumothorax. Clamping the chest tube (Option A) can lead to tension pneumothorax. Notifying the physician (Option B) is important but should be done after securing the chest tube. Repositioning the client in the Fowler's position (Option D) is not relevant in this scenario. By placing the tube in sterile water, the nurse can maintain the integrity of the closed drainage system and prevent complications.
Question 4 of 5
When using a cane for maximal support, the nurse is aware that the client should:
Correct Answer: A
Rationale: The correct answer is A: Hold the cane on the weaker side. This is correct because it provides maximal support and stability for the client. By holding the cane on the weaker side, the client can shift weight off the weaker leg, reducing strain and improving balance. Choice B is incorrect because weight should be shifted to the stronger side, not evenly distributed. Choice C is incorrect as keeping the elbow stiff can lead to discomfort and limited mobility. Choice D is incorrect as the stronger foot should advance ahead of the cane for stability.
Question 5 of 5
Mr. Tony is nervous about a colonoscopy scheduled for tomorrow. The nurse describes the test explaining that:
Correct Answer: B
Rationale: The correct answer is B because a colonoscopy is a procedure that allows visual examination of the large intestine. During a colonoscopy, a flexible tube with a camera is inserted through the rectum to examine the colon for abnormalities like polyps or cancer. The other choices are incorrect because: A: Visual examination of the esophagus and stomach is typically done using an upper endoscopy. C: A radiographic examination uses X-rays, not a camera, to visualize structures. D: A fluoroscopic examination involves real-time X-ray images and is often used for examining the small intestine, not the large intestine like in a colonoscopy.
