1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

2. Which of the following statements by a client indicates adequate preparation for magnetic resonance imaging?

Correct answer: A

Rationale: The correct statement is, '"I should wear earplugs during the test,"?' as MRI scanners produce loud noises requiring ear protection. Metal objects, including jewelry, are not allowed inside the MRI room due to safety concerns related to the magnetic field. Choices B, C, and D are incorrect. Choice B is wrong because metal objects, including jewelry, are not permitted in the MRI room. Choices C and D are incorrect as having a pacemaker or an artificial hip raises concerns due to the magnetic field in MRI, requiring special precautions or considerations. It is crucial for individuals with such implants to inform their healthcare provider to assess the risks and determine the appropriate course of action.

3. A child comes to the clinic with a skin rash. The maculopapular lesions are distributed around the mouth and have honey-colored drainage. The caregiver states that the rash is getting worse and seems to spread with the child's scratching. Which of the following advisory comments should be given?

Correct answer: C

Rationale: The scenario describes classic impetigo, characterized by maculopapular lesions with honey-colored drainage, typically caused by Staphylococcus aureus or Streptococcus pyogenes. Antibiotic therapy is usually indicated for impetigo. Chickenpox, a highly contagious disease, presents with a history of high fever followed by a vesicular rash, different from the described maculopapular lesions with honey-colored drainage. Choice A is incorrect as the presentation is not consistent with chickenpox. Choice B is incorrect because impetigo is contagious, especially through direct contact. Choice D is also incorrect as impetigo is a contagious skin infection regardless of others having open wounds or lesions.

4. What does carrying a donor card for organ donation mean?

Correct answer: C

Rationale: Carrying a donor card for organ donation signifies that an individual can decide to revoke their decision for organ donation at any point. This choice empowers the individual to change their mind regarding organ donation. The family or legally responsible party of a client still holds decision-making authority in the event that the client is considered for organ donation. When organ donation is being considered, all organs or tissues the donor wishes to donate are evaluated for donation suitability; it's not limited to just one organ or tissue. It's important to note that medical care for an individual is not altered to hasten the declaration of death for organ donation purposes; the focus is on providing immediate care and resuscitation to the individual.

5. While assisting a healthcare provider in assessing a hospitalized client, the healthcare provider is paged to report to the recovery room. The healthcare provider instructs the nurse verbally to change the solution and rate of the intravenous (IV) fluid being administered. What is the most appropriate nursing action in this situation?

Correct answer: B

Rationale: Verbal prescriptions should be avoided due to the risk of errors. If a verbal prescription is necessary, it should be promptly written and signed by the healthcare provider, typically within 24 hours. Following agency policies and procedures regarding verbal prescriptions is crucial. In this scenario, the most appropriate nursing action is to request the healthcare provider to document the prescription in the client's record before leaving the unit. Calling the nursing supervisor to accept the verbal prescription without documentation, telling the healthcare provider to delay treatment until documented, and directly changing the IV fluid based on verbal orders all pose risks and do not align with best practices in medication administration.
