Nursing Elites

1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

2. The nurse is caring for a client with an acute myocardial infarction. Which symptom requires immediate intervention?

• A. Dizziness
• B. Shortness of breath
• C. Severe chest pain
• D. Nausea and vomiting

Correct answer: C

Rationale: Severe chest pain is the hallmark symptom of an acute myocardial infarction (heart attack) and requires immediate intervention to prevent further damage to the heart muscle. Chest pain in this context is often described as crushing, pressure, tightness, or heaviness. It can radiate to the arms, neck, jaw, back, or upper abdomen. Other symptoms like dizziness, shortness of breath, nausea, and vomiting may also occur in acute myocardial infarction, but chest pain is the most critical sign requiring prompt action as it signifies inadequate blood flow to the heart muscle. Shortness of breath may indicate heart failure, while nausea and vomiting can be associated with the sympathetic response to myocardial infarction. Dizziness could result from decreased cardiac output but is not as specific to myocardial infarction as severe chest pain.

3. 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.

4. A toddler presenting with a history of intermittent skin rashes, hives, abdominal pain, and vomiting that occurs after ingesting milk products arrives at the clinic accompanied by the parents. Which type of testing should the nurse educate the toddler's family about?

• A. Complete blood count
• B. Lactose tolerance test
• C. Skin allergy testing
• D. Serum immunoglobulin E

Correct answer: D

Rationale: The correct answer is D, Serum immunoglobulin E (IgE) testing. This test can help diagnose food allergies, including milk protein allergies, in toddlers presenting with symptoms like skin rashes, hives, abdominal pain, and vomiting after consuming milk products. Skin allergy testing is used for allergies but may not be suitable for this age group due to developmental factors. Lactose intolerance, which is different from a milk allergy, is assessed through a lactose tolerance test, not IgE testing. A complete blood count (CBC) would not provide specific information related to food allergies.

5. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.
