1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. Which client assessment falls within the scope of practice for the practical nurse?

• A. An agitated client with bilateral wrist restraints
• B. New admission of a client with deep vein thrombosis
• C. Return of a post-anesthesia client following a colon resection
• D. Transfer of a client with sepsis from a long-term care facility

Correct answer: B

Rationale: The correct answer is B because assessing a new deep vein thrombosis (DVT) patient is within the scope of practical nursing. It involves monitoring and supporting the circulatory system health, which is a common responsibility for practical nurses. Choices A, C, and D involve scenarios that are typically beyond the initial assessment and care provided by practical nurses. An agitated client with bilateral wrist restraints may require immediate intervention by higher-level healthcare providers due to safety concerns and potential underlying issues. The return of a post-anesthesia client following a colon resection and the transfer of a client with sepsis involve more specialized care that goes beyond the typical responsibilities of a practical nurse, often requiring interventions from registered nurses or physicians.

3. An elderly client is concerned about constipation during a flight. What should the nurse recommend?

• A. Use an over-the-counter stool softener when needed
• B. Eat a high protein diet
• C. Increase the fluid intake in the diet
• D. Decrease the fat content in the diet

Correct answer: C

Rationale: The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.

4. The nurse is caring for a client who has just returned from surgery with an indwelling urinary catheter in place. What is the most important assessment for the nurse to make?

• A. Check for catheter patency
• B. Assess the color of the urine
• C. Measure the urine output
• D. Ensure the catheter tubing is secure

Correct answer: C

Rationale: The most important assessment for the nurse to make in this situation is to measure the urine output. This assessment is crucial in monitoring kidney function and fluid balance after surgery. While checking for catheter patency is important, it is not as critical as measuring urine output. Assessing the color of the urine can provide some information about kidney function, but measuring output gives a more accurate assessment. Ensuring the catheter tubing is secure is essential to prevent dislodgement but is not the most critical assessment to make at this time.

5. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.
