Nokea
A charge nurse is discussing the use of applying ice to a client's injured knee with a newly licensed nurse. Which of the following is a benefit of this treatment?
- A. Systemic analgesic effect
- B. Increase in metabolism
- C. Decreased capillary permeability
- D. Vasodilation
Correct Answer: C
Rationale: The correct answer is C: Decreased capillary permeability. Ice application helps decrease capillary permeability, which in turn reduces swelling and inflammation at the injury site. This vasoconstriction effect helps to limit the extent of the injury. Choices A, B, and D are incorrect. Applying ice locally does not produce a systemic analgesic effect but rather a localized numbing effect. It does not increase metabolism but rather slows down metabolic processes in the affected area. Additionally, ice application causes vasoconstriction, not vasodilation.

- A. I cannot change my instructions once they are made
- B. My doctor will need to approve my advance directives
- C. I need an attorney to witness my signature on the advance directives
- D. I have the right to refuse treatment
Correct Answer: D
Rationale: The correct answer is D: 'I have the right to refuse treatment.' This statement indicates an understanding of advance directives because advance directives allow individuals to express their treatment preferences, including the right to refuse treatment if they choose to do so. Choice A is incorrect because individuals can update or change their advance directives as needed. Choice B is incorrect because advance directives are based on the individual's preferences, not the doctor's approval. Choice C is incorrect as witnessing an advance directive typically requires a witness who is not an attorney, depending on the state's specific requirements.

A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?
- A. Paradoxical pulse
- B. Dependent edema
- C. Pericardial friction rub
- D. Substernal chest pain
Correct Answer: A
Rationale: The correct answer is A: Paradoxical pulse. Paradoxical pulse, which is a significant drop in systolic blood pressure during inspiration, indicates cardiac tamponade, a life-threatening complication of pericarditis. This finding requires immediate attention as it suggests potential compromised cardiac function. Choices B, C, and D are associated with pericarditis but do not indicate the same level of urgency as paradoxical pulse.
A nurse is reviewing dietary assessment findings for a client who is Jewish and observes kosher dietary practices. Which of the following behaviors should the nurse expect to find?
- A. Leavened bread may be eaten during Passover
- B. Shellfish is commonly consumed in the diet
- C. Meat and dairy products are eaten separately
- D. Fasting from meat occurs during Hanukkah
Correct Answer: C
Rationale: The correct answer is C. According to kosher dietary laws, meat and dairy products cannot be consumed together. This practice stems from the prohibition in Jewish law against cooking a young animal in its mother's milk. Therefore, the nurse should expect to find that meat and dairy products are eaten separately. Choices A, B, and D are incorrect. Leavened bread is not eaten during Passover (Choice A), shellfish is not consumed in the kosher diet (Choice B), and fasting from meat does not occur during Hanukkah (Choice D).
A nurse is completing an assessment of a newborn who is 2 hours old. Which of the following findings is indicative of cold stress?
- A. Respiratory rate of 60 per minute
- B. Jitteriness of the hands
- C. Diaphoresis
- D. Bounding peripheral pulses
Correct Answer: B
Rationale: Jitteriness of the hands is a classic sign of cold stress in newborns, indicating that the infant is having difficulty maintaining a stable body temperature. Cold stress can lead to hypoglycemia and increased oxygen consumption. The other options (A, C, and D) are not directly associated with cold stress in newborns. A respiratory rate of 60 per minute may be within the normal range for a newborn. Diaphoresis (excessive sweating) and bounding peripheral pulses are not specific signs of cold stress in newborns.
