1. A nonimmunized child appears at the clinic with a visible rash. Which of the following observations indicates the child may have rubeola (measles)?

A. Small blue-white spots are visible on the oral mucosa.
B. The rash begins on the trunk and spreads outward.
C. There is low-grade fever.
D. The lesions have a "teardrop-on-a-rose-petal"? appearance.

Correct answer: A

Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.

2. Which of the following is an example of a living will?

A. A client's son has been appointed to make his healthcare decisions if he becomes incapacitated
B. A client has designated which of his children will receive his home and property before he dies
C. A client has instructions that he does not want to be resuscitated through chest compressions if his heart stops beating
D. A client designates what type of burial or cremation services he would want after his death

Correct answer: C

Rationale: A living will is a type of advanced directive that a client develops to stipulate his preferences for healthcare in the event that he is unable to do so. This includes specific instructions about medical treatments in certain situations. Choice C is the correct answer as it reflects a scenario where the client has clearly outlined their preference regarding resuscitation through chest compressions. Choices A, B, and D do not pertain to a living will. Choice A involves a healthcare proxy or agent, choice B involves a will or estate planning, and choice D involves funeral or burial arrangements, which are not part of a living will.

3. In which of the following examples would informed consent not be required?

A. A patient is apprehensive about an upcoming surgery and chooses not to learn of the risks involved with the procedure.
B. A child is rushed to the Emergency Room after falling from a third-story window.
C. An adult in a coma in a mental health institution with no listed next of kin.
D. Informed consent is not required in any of the above examples.

Correct answer: D

Rationale: In emergency situations where immediate treatment is necessary to prevent further harm or save a life, such as in option B where a child is rushed to the Emergency Room after a fall, informed consent may be waived to provide prompt care. In option A, though the patient is apprehensive about surgery and chooses not to learn the risks, informed consent is not required as it is the patient's right to refuse information. In option C, when an adult is in a coma with no next of kin listed, decisions may be made in the patient's best interest following legal and ethical guidelines. Therefore, informed consent is not needed in any of the scenarios presented.

4. A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?

A. Elevated fibrinogen level
B. Prolonged PT
C. Elevated platelet count
D. Depressed d-dimer level

Correct answer: B

Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.

5. You are caring for a patient with newly diagnosed multiple sclerosis. Discharge instructions will likely include all of the following EXCEPT:

A. PT referral for development of a planned exercise program
B. Avoidance of prolonged sun exposure
C. Hot baths to promote muscle relaxation
D. Instructions to evaluate the home environment to ensure safety

Correct answer: C

Rationale: Discharge instructions for a patient with newly diagnosed multiple sclerosis should focus on promoting safety and minimizing exacerbations. Hot baths should be avoided as excessive heat can trigger acute symptoms. Therefore, instructions may include PT referral for an exercise program to maintain mobility, avoidance of prolonged sun exposure to prevent symptom exacerbation, and guidance to evaluate the home environment for safety as symptoms progress. Hot baths are not recommended due to the risk of exacerbating symptoms, making it the correct answer. Choices A, B, and D are appropriate for a patient with multiple sclerosis, as they address mobility, symptom management, and safety concerns, respectively.
