Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is receiving supplemental oxygen. The client reports feeling short of breath and has a respiratory rate of 28 breaths per minute. What should the nurse do first?

• A. Increase the oxygen flow rate
• B. Notify the healthcare provider
• C. Administer a bronchodilator
• D. Elevate the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed promotes lung expansion and improves oxygenation, making it the priority intervention for a client with shortness of breath. This position helps in maximizing lung expansion and aiding ventilation-perfusion matching in patients with COPD. Increasing the oxygen flow rate may be necessary but should come after optimizing the client's positioning. Notifying the healthcare provider and administering a bronchodilator are not the initial interventions for addressing shortness of breath in a client with COPD.

2. A client with pneumonia is receiving antibiotics and oxygen therapy. What assessment finding requires immediate intervention?

• A. Productive cough with yellow sputum.
• B. Oxygen saturation of 88%.
• C. Respiratory rate of 20 breaths per minute.
• D. Heart rate of 90 beats per minute.

Correct answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical condition requiring immediate intervention to improve oxygenation. Hypoxemia can lead to tissue hypoxia and further complications. A productive cough with yellow sputum is common in pneumonia but may not require immediate intervention unless it worsens or is associated with other concerning symptoms. A respiratory rate of 20 breaths per minute is within the normal range, indicating adequate ventilation. A heart rate of 90 beats per minute is also within a normal range and may not require immediate intervention unless it is accompanied by other abnormal findings.

3. The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?

• A. Platelet count and red blood cell count.
• B. White blood cell count and sputum culture.
• C. Hemoglobin A1c and glucose tolerance test.
• D. Arterial blood gases and serum electrolytes.

Correct answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

4. An adolescent who was diagnosed with diabetes mellitus Type 1 at the age of 9 is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of ketoacidosis?

• A. Had a cold and ear infection for the past two days
• B. Missed a dose of insulin
• C. Did not follow dietary restrictions
• D. Overexerted during exercise

Correct answer: A

Rationale: The correct answer is A. Infections, like a cold and ear infection, increase the body's metabolic needs and insulin resistance, making diabetic ketoacidosis (DKA) more likely. While missing insulin doses or not following dietary restrictions can trigger DKA, an illness is the most common precipitating factor in pediatric Type 1 diabetes. Option B is less likely as missing insulin can lead to hyperglycemia but might not be the immediate cause of ketoacidosis. Option C can contribute to DKA over time, but the acute trigger is usually an illness. Option D, overexertion during exercise, is less likely to cause DKA compared to an infection.

5. A client with heart failure receiving furosemide develops muscle weakness. What is the nurse's priority action?

• A. Administer potassium supplements as prescribed.
• B. Monitor the client’s potassium levels.
• C. Instruct the client to increase their salt intake.
• D. Discontinue the furosemide.

Correct answer: B

Rationale: Muscle weakness in a client receiving furosemide (a diuretic) is often a sign of hypokalemia, as furosemide increases potassium loss. Monitoring potassium levels is essential to identify and address any imbalances and prevent complications such as arrhythmias. Administering potassium supplements without monitoring the levels can lead to hyperkalemia, which has its own set of serious complications. Instructing the client to increase salt intake is not appropriate in this situation as it does not address the underlying electrolyte imbalance. Discontinuing furosemide abruptly can worsen heart failure symptoms; therefore, monitoring potassium levels and adjusting the treatment accordingly is the most appropriate action.
