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. Elderly patients are more prone to dehydration than younger people because the elderly ___________.

• A. drink more coffee and tea
• B. have more stomach mucus production
• C. have more saliva
• D. have less sense of thirst

Correct answer: D

Rationale: Elderly patients are prone to dehydration because they have a lower and diminished sense of thirst. This reduced sensation of thirst makes them less likely to drink an adequate amount of fluids, leading to dehydration. While it is true that elderly individuals may also have changes such as decreased stomach mucus production and saliva production, these factors do not directly contribute to dehydration. Drinking more coffee and tea, as mentioned in choice A, is not a consistent behavior among all elderly individuals and is not a primary reason for their increased risk of dehydration.

3. Mrs. F has been diagnosed with hyperparathyroidism. Which of the following complications is Mrs. F at highest risk of developing?

• A. Hyponatremia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypercalcemia

Correct answer: D

Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.

4. Which information given by a 70-year-old patient during a health history indicates to the nurse that the patient should be screened for hepatitis C?

• A. The patient had a blood transfusion in 2005
• B. The patient used IV drugs about 20 years ago
• C. The patient frequently eats in fast-food restaurants
• D. The patient traveled to a country with poor sanitation

Correct answer: B

Rationale: The correct answer is 'The patient used IV drugs about 20 years ago.' Any patient with a history of IV drug use should be tested for hepatitis C due to the increased risk of transmission through sharing needles. Blood transfusions given after 1992, when an antibody test for hepatitis C became available, do not pose a risk for hepatitis C. Hepatitis C is not spread by the oral-fecal route, so contaminated food or traveling to countries with poor sanitation are not direct risk factors for hepatitis C.

5. If you are caring for a patient of the Hindu culture, what may you anticipate regarding visitors?

• A. Limited visitors, respectful of privacy
• B. Family members only
• C. Large number of visitors/community support
• D. None of the above

Correct answer: C

Rationale: In Hindu culture, there is a strong sense of community and support. It is common for a patient to receive a large number of visitors, indicative of the community coming together to provide emotional and practical support. This support network is crucial for the patient's well-being and healing process. Option A, limited visitors, is incorrect as the Hindu culture values community involvement. Option B, family members only, is incorrect as the support network extends beyond just family. Option D, none of the above, is incorrect as the Hindu culture typically involves community support and a significant number of visitors.
