Nursing Elites

1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

2. The nurse is preparing to administer an IV dose of ciprofloxacin to a client with a urinary tract infection. Which client data requires the most immediate intervention by the nurse?

• A. Serum creatinine of 4.5 mg/dL (398 μmol/L SI)
• B. Temperature of 101.3°F
• C. Blood pressure of 140/90 mmHg
• D. Heart rate of 88 bpm

Correct answer: A

Rationale: A serum creatinine level of 4.5 mg/dL indicates severe renal impairment, which requires immediate attention before administering ciprofloxacin. Elevated serum creatinine levels suggest decreased kidney function, and giving ciprofloxacin can further harm the kidneys. Monitoring and addressing renal function are crucial to prevent worsening of renal impairment and potential drug toxicity. The temperature, blood pressure, and heart rate are important parameters to assess, but in this scenario, the priority is to address the severe renal impairment before proceeding with ciprofloxacin administration.

3. A school nurse is called to the soccer field because a child has a nosebleed (epistaxis). In what position should the nurse place the child?

• A. Sitting up and leaning forward
• B. Lying flat with legs elevated
• C. Lying on the side with the head slightly raised
• D. Sitting up and tilting the head back

Correct answer: A

Rationale: The child with a nosebleed (epistaxis) should be placed in a sitting position, leaning forward, to prevent blood from flowing down the throat. This position helps to control the bleeding and prevents the child from swallowing blood, which can cause nausea or vomiting. Choice B is incorrect because elevating the legs is not recommended for nosebleeds. Choice C is incorrect because lying on the side with the head slightly raised is not the optimal position for managing a nosebleed. Choice D is incorrect because tilting the head back can lead to blood flowing down the throat and potentially cause aspiration.

4. The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which assessment finding requires immediate intervention?

• A. Crepitus around the tracheostomy site
• B. Dry and cracked tracheostomy site
• C. Mucous plugging of the tracheostomy tube
• D. Yellowing of the skin around the tracheostomy site

Correct answer: C

Rationale: Mucous plugging of the tracheostomy tube is the most concerning assessment finding in a client with a tracheostomy. It can lead to airway obstruction, which requires immediate intervention to ensure the client's airway remains patent. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but is not as urgent as a blocked airway. A dry and cracked tracheostomy site may indicate poor skin integrity but does not pose an immediate threat to the client's airway. Yellowing of the skin around the tracheostomy site could suggest a localized infection, but it is not as critical as a potential airway obstruction caused by mucous plugging.

5. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?

• A. Uncontrollable drooling.
• B. Inability to raise voice.
• C. Tingling of extremities.
• D. Eyelid drooping.

Correct answer: A

Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.
