Nursing Elites

1. 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.

2. Which of the following situations might warrant a laboratory magnesium level?

• A. Hyperthyroidism
• B. Arthritis
• C. Ulcerative colitis
• D. Depression

Correct answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.

3. A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?

• A. Contact the physician immediately
• B. Administer a bolus of 50 cc of D20W through the IV
• C. Administer 10 units of regular insulin
• D. Give the client 6 oz. of orange juice

Correct answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.

4. The discharge planning team is discussing plans for the dismissal of a 16-year-old admitted for complications associated with asthma. The client's mother has not participated in any of the discharge planning processes but has stated that she wants to be involved. Which of the following reasons might prohibit this mother from participating in discharge planning?

• A. The client is an emancipated minor
• B. The mother has to work and is unavailable
• C. The client has a job and a driver's license
• D. The mother does not speak English

Correct answer: A

Rationale: In this scenario, the correct answer is that the client is an emancipated minor. Emancipated minors, even if they are under the age of 18, have the legal right to make decisions about their own healthcare and planning, which may include not wanting their parent involved in the discharge planning process. This status grants them independence from parental involvement in certain situations. The other choices are incorrect because the mother's work schedule, the client's job and possession of a driver's license, and the mother's language proficiency do not inherently prevent her from participating in the discharge planning process, unlike the legal status of being an emancipated minor.

5. What action by the nurse will be most effective in decreasing the spread of pertussis in a community setting?

• A. Providing supportive care to patients diagnosed with pertussis
• B. Teaching family members about the importance of careful handwashing
• C. Teaching patients about the necessity of adult pertussis immunizations
• D. Encouraging patients to complete the prescribed course of antibiotics

Correct answer: C

Rationale: The most effective action by the nurse to decrease the spread of pertussis in a community setting is to teach patients about the necessity of adult pertussis immunizations. The increased rate of pertussis in adults is often attributed to waning immunity after childhood immunization. Immunization is highly effective in protecting communities from infectious diseases. While teaching about handwashing is important for overall infection control, pertussis is primarily spread through respiratory droplets and contact with secretions. Providing supportive care does not significantly impact the disease course or transmission risk. Encouraging completion of antibiotics may help reduce transmission, but patients likely have already spread the disease by the time the diagnosis is made. Therefore, the emphasis should be on prevention through immunization to reduce the spread of pertussis.
