Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. A nursing student caring for a 6-month-old infant is asked to collect a sample for urinalysis from the infant. How should the student collect the specimen?

• A. Catheterizing the infant using the smallest available Foley catheter
• B. Attaching a urinary collection device to the infant's perineum for collection
• C. Obtaining the specimen from the diaper by squeezing the diaper after the infant voids
• D. Noting the time of the next expected voiding and then preparing a specimen cup for the urine

Correct answer: B

Rationale: The correct method for collecting a urine sample from an infant for urinalysis is by attaching a urinary collection device to the infant's perineum. This device is a plastic bag with an adhesive opening that allows it to be secured to the perineum to collect urine. Catheterizing the infant with a Foley catheter should not be done unless specifically prescribed due to the risk of infection. Obtaining the specimen from the diaper by squeezing it after the infant voids may not provide an accurate sample for urinalysis. Trying to predict the time of the next voiding to prepare a specimen cup is not practical or reliable in ensuring an appropriate sample for urinalysis.

3. Diabetic patients are more prone to ____________ than other people without this chronic disorder.

• A. infection
• B. increased oxygen saturation
• C. low fibrinogen
• D. constipation

Correct answer: A

Rationale: Diabetic patients are more prone to infection than other people without this chronic disorder. Diabetes weakens the immune system and impairs the body's ability to fight off infections, making individuals with diabetes more susceptible to various types of infections. Increased oxygen saturation, low fibrinogen, and constipation are not directly related to diabetes or the increased infection risk associated with the condition. Increased oxygen saturation is actually a positive health indicator, low fibrinogen levels are not a common issue in diabetes, and constipation is not a primary concern when comparing diabetic patients to others without the condition.

4. Following a diagnosis of acute glomerulonephritis (AGN) in their 6-year-old child, the parent remarks, 'We just don't know how he caught the disease!' The nurse's response is based on an understanding that

• A. AGN is a streptococcal infection that involves the kidney tubules
• B. The disease is easily transmissible in schools and camps
• C. The illness is usually associated with chronic respiratory infections
• D. It is not 'caught' but is a response to a previous B-hemolytic strep infection

Correct answer: D

Rationale: Acute glomerulonephritis (AGN) is generally considered an immune-complex disease in response to a previous B-hemolytic streptococcal infection, typically occurring 4 to 6 weeks prior. It is not an infectious disease but a noninfectious renal condition. Therefore, the parent's belief that the child 'caught' the disease is inaccurate. Choice A is incorrect because AGN is not a direct streptococcal infection involving the kidney tubules but an immune response to a prior streptococcal infection. Choice B is incorrect as AGN is not easily transmissible in schools and camps. Choice C is incorrect as AGN is not usually associated with chronic respiratory infections but with a previous streptococcal infection.

5. When teaching the client with tuberculosis about follow-up home care, the nurse should emphasize that a laboratory appointment for which of the following lab tests is critical?

• A. Liver function
• B. Kidney function
• C. Blood sugar
• D. Cardiac enzymes

Correct answer: A

Rationale: The nurse should emphasize the importance of monitoring liver function tests in clients taking INH due to the risk of hepatocellular injury and hepatitis associated with this medication. Regular assessment of liver enzymes can help detect liver damage early. Monitoring kidney function, blood sugar levels, or cardiac enzymes is not specifically required for clients taking INH and tuberculosis treatment.
