Nursing Elites

1. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?

• A. Instruct the mother to give sugar water only.
• B. Offer the infant oral rehydration every 2 hours.
• C. Provide Pedialyte feedings via nasogastric tube.
• D. Maintain intravenous fluid therapy.

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

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. The nurse is preparing to administer an intramuscular injection to an adult client. Which site should the nurse select?

• A. Deltoid muscle
• B. Ventrogluteal muscle
• C. Vastus lateralis muscle
• D. Dorsogluteal muscle

Correct answer: B

Rationale: The ventrogluteal site is preferred for intramuscular injections in adults because it is free from major blood vessels and nerves, reducing the risk of injury. The deltoid muscle can be used for smaller volumes of medication, primarily vaccines. The vastus lateralis muscle is commonly used in infants, toddlers, and young children. The dorsogluteal muscle site is discouraged due to its proximity to the sciatic nerve, increasing the risk of injury or nerve damage.

4. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

5. A client is receiving lactulose for signs of hepatic encephalopathy. To evaluate the therapeutic response, which assessment should the nurse obtain?

• A. Percussion of the abdomen.
• B. Blood glucose level.
• C. Serum electrolytes.
• D. Level of consciousness.

Correct answer: D

Rationale: The correct answer is D: Level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy, which can affect brain function. Therefore, monitoring the client's level of consciousness is crucial to evaluate the therapeutic response. Changes in consciousness can indicate the effectiveness of lactulose in reducing ammonia levels. Choices A, B, and C are incorrect because while they are important assessments in various conditions, they are not specifically related to evaluating the therapeutic response of lactulose in hepatic encephalopathy.
