Nursing Elites

1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Serum magnesium level

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.

2. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

3. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

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. When organizing home visits for the day, which older client should the home health nurse plan to visit first?

• A. A woman who takes naproxen (Naprosyn) and reports a recent onset of dark, tarry stools.
• B. A man who receives weekly injections of epoetin (Procrit) for a low serum iron level.
• C. A man with emphysema who smokes and is complaining of white patches in his mouth.
• D. A frail woman with heart failure who reported a 2-pound weight gain in the last week.

Correct answer: A

Rationale: The correct answer is A. Dark, tarry stools may indicate gastrointestinal bleeding, a potentially life-threatening condition that requires immediate attention. Visiting this client first is crucial for prompt assessment and intervention. Choices B, C, and D do not present immediate life-threatening conditions that require urgent attention compared to the potential emergency indicated by dark, tarry stools.
