Nursing Elites

1. Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?

• A. Liver
• B. Kidneys
• C. Brain
• D. Muscles

Correct answer: C

Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death. Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.

2. What is the action of Metformin?

• A. Decreasing intestinal glucose absorption
• B. Increasing sensitivity to insulin
• C. Decreasing hepatic glucose production
• D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

3. A client has a new prescription for Atenolol. Which of the following client statements indicates an understanding of the teaching?

• A. I should monitor my blood pressure regularly.
• B. I will take this medication at bedtime.
• C. I will take this medication with a high-fat meal.
• D. I should increase my intake of potassium-rich foods.

Correct answer: A

Rationale: The correct answer is A. Clients taking Atenolol, a beta-blocker, should monitor their blood pressure regularly to ensure the medication is effectively managing their condition. Monitoring blood pressure helps in assessing the drug's effectiveness and identifying any potential side effects that may influence blood pressure levels. Choices B, C, and D are incorrect because taking Atenolol at bedtime, with a high-fat meal, or increasing potassium-rich foods intake are not recommended actions associated with this medication and do not demonstrate an understanding of the teaching.

4. A healthcare professional is caring for a hospitalized client who has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should the healthcare professional prepare to transfuse?

• A. Whole blood
• B. Platelets
• C. Fresh frozen plasma
• D. Packed red blood cells

Correct answer: C

Rationale: Fresh frozen plasma is the correct choice for a client with an elevated aPTT because it contains essential coagulation factors that can help correct coagulopathy and prevent bleeding. It is rich in clotting factors like fibrinogen, factors V and VIII, which are crucial in maintaining proper blood clotting function. Whole blood (Choice A) is not typically used to correct coagulopathy and is more suitable for situations requiring both volume and oxygen-carrying capacity. Platelets (Choice B) are indicated for thrombocytopenia, not for correcting coagulation factors. Packed red blood cells (Choice D) are used to increase oxygen-carrying capacity in cases of anemia, not for correcting coagulopathy.

5. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?

• A. Sodium
• B. Potassium
• C. Magnesium
• D. Calcium

Correct answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.
