1. A healthcare provider is delegating client care to assistive personnel. Which of the following tasks should the healthcare provider delegate?
- A. Evaluating healing of an incision
- B. Inserting an NG Tube
- C. Performing a simple dressing change
- D. Changing IV tubing
Correct answer: C
Rationale: The correct task that a healthcare provider should delegate to assistive personnel is performing a simple dressing change. Assistive personnel are trained and competent in performing basic wound care activities like simple dressing changes. Evaluating the healing of an incision requires clinical judgment and assessment skills that are typically performed by licensed healthcare professionals, such as nurses or physicians. Inserting an NG tube and changing IV tubing involve invasive procedures that require specialized training and skills, making them tasks that should be performed by licensed healthcare providers rather than assistive personnel.
2. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?
- A. Decreased calcium
- B. Elevated potassium
- C. Increased sodium
- D. Low hemoglobin
Correct answer: A
Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
3. A nurse in a primary care clinic is assessing a client who has a history of herpes zoster. Which of the following findings suggests that the client has postherpetic neuralgia?
- A. Linear clusters of vesicles on the right shoulder.
- B. Purulent drainage from both eyes.
- C. Decreased white blood cell count.
- D. Report of continued pain following resolution of the rash.
Correct answer: D
Rationale: The correct answer is D: Report of continued pain following resolution of the rash. Postherpetic neuralgia is a complication of herpes zoster characterized by persistent pain that continues even after the rash has resolved. This pain can be severe and debilitating, affecting the quality of life of the individual. Choices A, B, and C are incorrect because linear clusters of vesicles on the right shoulder would suggest an active herpes zoster outbreak, purulent drainage from both eyes would indicate an eye infection unrelated to postherpetic neuralgia, and a decreased white blood cell count is not typically associated with postherpetic neuralgia.
4. A nurse on a med-surg unit is providing care for four clients. The nurse should identify which of the following situations as an ethical dilemma?
- A. A surgeon who removed the wrong kidney during a surgical procedure refuses to take responsibility for her actions
- B. A client who has a new colostomy refuses to follow instructions from the ostomy therapist because she 'doesn’t like him'
- C. The family of a client who has a terminal illness asks that the provider not disclose the diagnosis to the client
- D. A client who has Crohn’s disease reports that his prescription drug plan will not cover his medications
Correct answer: C
Rationale: The correct answer is C. It is an ethical dilemma when the family of a client with a terminal illness asks healthcare providers not to inform the client of their diagnosis. This situation poses a conflict between respecting the client's right to know the truth about their condition (autonomy and truth-telling principles) and honoring the family's wishes. Choices A, B, and D do not present ethical dilemmas. Choice A involves professional accountability and responsibility, Choice B involves a client's personal preference, and Choice D involves financial challenges.
5. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?
- A. 400 mg
- B. 200 mg
- C. 1600 mg
- D. 100 mg
Correct answer: A
Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
