Nursing Elites

1. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

• A. It helps reduce the production of intestinal gases.
• B. It ensures clearer imaging by emptying the stomach.
• C. It prevents the risk of aspiration during the procedure.
• D. It is a standard procedure for all surgical interventions.

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

2. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?

• A. Bed rest with bathroom privileges only
• B. Frequent, short walks with assistance
• C. Range of motion exercises to the knee every four hours
• D. Leg elevation to reduce swelling

Correct answer: B

Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.

3. A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: B

Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.

4. The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.

5. Which structures are located in the subcutaneous layer of the skin?

• A. Sebaceous and sweat glands
• B. Melanin and keratin
• C. Sensory receptors and hair follicles
• D. Adipose cells and blood vessels

Correct answer: D

Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
