Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is preparing to administer a dose of vancomycin IV to a client who has a methicillin-resistant Staphylococcus aureus (MRSA) infection. Which of the following actions should the nurse take?

• A. Administer the medication over 15 minutes.
• B. Monitor the client's urine output every 8 hours.
• C. Check the client's creatinine level before administering the medication.
• D. Assess the client for a history of allergies to antibiotics.

Correct answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

3. A nurse is caring for a client who has schizophrenia. Which of the following findings should the nurse expect?

• A. Decreased level of consciousness
• B. Inability to identify common objects
• C. Preoccupation with somatic disturbances
• D. Poor problem-solving ability

Correct answer: B

Rationale: The correct answer is B: Inability to identify common objects. Clients with schizophrenia often experience cognitive deficits, such as difficulty in identifying common objects. This can be attributed to impairments in perception and cognition. Choices A, C, and D are not typically associated with schizophrenia. Decreased level of consciousness is more indicative of conditions like head injuries or metabolic disturbances. Preoccupation with somatic disturbances is commonly seen in somatic symptom disorders, not schizophrenia. Poor problem-solving ability is a characteristic of conditions affecting executive functioning like dementia, rather than schizophrenia.

4. A client is receiving chemotherapy and is being taught about preventing infection. Which of the following instructions should the nurse include?

• A. Take your temperature daily.
• B. Avoid fresh fruits and vegetables.
• C. Limit your intake of high-protein foods.
• D. Increase your intake of high-fat foods.

Correct answer: B

Rationale: Clients receiving chemotherapy are instructed to avoid fresh fruits and vegetables to lower the risk of infection. Fresh produce may harbor bacteria or other pathogens that could be harmful to individuals with compromised immune systems. Taking the temperature daily may be important but is not directly related to preventing infection. Limiting high-protein foods is not necessary unless there are specific dietary restrictions due to the treatment plan. Increasing the intake of high-fat foods is not recommended during chemotherapy as a high-fat diet may lead to other health issues.

5. Which medication is commonly prescribed for a patient with a history of heart failure?

• A. Furosemide
• B. Metoprolol
• C. Digoxin
• D. Aspirin

Correct answer: A

Rationale: Furosemide is the correct answer. It is a common diuretic used in patients with heart failure to reduce fluid overload. Metoprolol (Choice B) is a beta-blocker often prescribed to manage heart failure symptoms by improving heart function. Digoxin (Choice C) is used in heart failure patients to help the heart beat stronger and with a more regular rhythm. Aspirin (Choice D) is not typically prescribed for heart failure but may be used in patients with heart disease for its antiplatelet effects.
