Introduction to Critical Care Nursing 8th Edition Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A patient with a systemic bacterial infection feels cold and has a shaking chill. Which assessment finding will the nurse expect next?
Correct Answer: C
Rationale: The correct answer is C: Rising body temperature. When a patient with a systemic bacterial infection experiences a shaking chill, it indicates that the body is trying to generate heat to combat the infection. The next assessment finding the nurse would expect is a rising body temperature as the body's immune response kicks in to fight off the infection. Skin flushing (choice A) is less likely as the patient is feeling cold initially. Muscle cramps (choice B) are not typically associated with this scenario. Decreasing blood pressure (choice D) may be a later complication but is not the immediate next assessment finding after a shaking chill.
Question 5 of 5
A new nurse reads a client has a wound “healing by second intention” and asks what that means. Which description by the charge nurse is most accurate?
Correct Answer: C
Rationale: The correct answer is C because healing by second intention refers to a wound that is left open to fill in with granulation tissue. This process allows for the wound to heal from the inside out, promoting tissue regeneration. Explanation: 1. Option A is incorrect because healing by second intention does not involve approximating or stitching wound edges together. 2. Option B is incorrect because stapling a wound after an infection does not necessarily relate to healing by second intention. 3. Option D is incorrect because although the wound may be contaminated, healing by second intention does not mean it cannot be closed at all. In summary, the correct answer is C because it accurately describes the process of healing by second intention, which involves allowing an open wound to fill in with granulation tissue.
