Nursing Elites

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. 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.

3. A victim of a gunshot wound to the abdomen has been admitted to the hospital, accompanied by a police officer. When questioned, the officer states that the patient is a suspect in a homicide, which occurred as part of the same incident. A small child was killed as the result of a stray bullet. The patient is combative, yells that he's in pain and demands medication. What is your most appropriate response?

• A. Tell him you'll take care of him after your other patients
• B. Reinforce restraints
• C. Perform a pain assessment and administer pain medication
• D. Ask the officer for more details of the incident

Correct answer: C

Rationale: The most appropriate and caring response is to perform a pain assessment and administer the pain medication that has been ordered. Regardless of personal feelings about any given situation, the nurse's responsibility is to provide unbiased, appropriate, and supportive care, as stated in the American Nurses Association (ANA) Code of Ethics. Choice A is not appropriate as it disregards the patient's immediate need for pain relief. Choice B may escalate the situation and is not the priority in this case. Choice D is not the immediate action needed to address the patient's pain and distress.

4. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

5. Which of the following components is associated with hypertonic dehydration?

• A. Plasma sodium levels above 150 mEq/L
• B. Fluid moves from extracellular space to intracellular space
• C. Water loss is greater than electrolyte loss
• D. Physical signs and symptoms are grossly apparent

Correct answer: C

Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.
