Nursing Elites

1. A healthcare professional is reviewing a client’s medications. They include cimetidine and imipramine. Knowing that cimetidine decreases the metabolism of imipramine, the healthcare professional should identify that this combination is likely to result in which of the following effects?

• A. Decreased therapeutic effects of cimetidine
• B. Increased risk of imipramine toxicity
• C. Decreased risk of adverse effects of cimetidine
• D. Increased therapeutic effects of imipramine

Correct answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

2. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

3. A charge nurse is observing a newly licensed nurse perform tracheostomy care for a client. Which of the following actions by the newly licensed nurse requires intervention?

• A. Obtaining cotton balls for the tracheostomy care
• B. Using a sterile water bottle
• C. Checking the suction equipment
• D. Wearing a sterile gown

Correct answer: A

Rationale: The correct answer is A. Obtaining cotton balls for tracheostomy care is not recommended due to the risk of fiber contamination. Sterile gauze should be used instead. Choice B, using a sterile water bottle, is a correct and appropriate action for tracheostomy care to maintain cleanliness. Choice C, checking the suction equipment, is also a necessary step to ensure it is functioning properly for the procedure. Choice D, wearing a sterile gown, is a standard precaution to maintain a sterile environment during tracheostomy care.

4. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Blood urea nitrogen (BUN) of 45 mg/dL
• C. Serum potassium of 6.5 mEq/L
• D. Hemoglobin of 10 g/dL

Correct answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

5. During a neurological assessment, a healthcare provider is evaluating a client's balance. Which of the following examinations should the provider use for this purpose?

• A. Romberg test
• B. Deep tendon reflexes
• C. Mini-Mental State Examination
• D. Babinski reflex

Correct answer: A

Rationale: The Romberg test is utilized to assess the client's balance and proprioception by having them stand with their eyes closed. This test helps evaluate sensory ataxia, a condition where an individual's balance is affected due to impaired sensory input. Deep tendon reflexes (Choice B) are assessed by tapping a tendon with a reflex hammer to evaluate the integrity of the spinal cord and peripheral nerves; this is not directly related to balance assessment. The Mini-Mental State Examination (Choice C) is a cognitive screening tool used to assess cognitive impairment or dementia, not balance. The Babinski reflex (Choice D) is elicited by stroking the sole of the foot to assess neurologic function, particularly in the corticospinal tract, and is not specific to balance evaluation.
