1. What activities best describe the work of the placenta during pregnancy?

• A. surrounding and cushioning the fetus
• B. combining maternal and fetal blood stores to exchange nutrients
• C. producing hormones that maintain the pregnancy
• D. absorbing vitamins and minerals that can be transferred to the fetus

Correct answer: C

Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.

2. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

• A. water
• B. protein
• C. fat
• D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.

3. A client states they are taking greater than the recommended daily allowance of vitamin E to prevent cataracts. Which complication should the nurse educate the client as related to taking excessive amounts of vitamin E?

• A. Lung cancer
• B. Stroke
• C. Diarrhea
• D. Liver damage

Correct answer: B

Rationale: The correct answer is B: Stroke. High doses of vitamin E supplements have been associated with an increased risk of hemorrhagic stroke due to its blood-thinning properties. Option A, lung cancer, is not a known complication of excessive vitamin E intake. Option C, diarrhea, is more commonly associated with excessive intake of other vitamins or minerals. Option D, liver damage, is not a commonly reported complication of vitamin E overdose.

4. The nurse understands that malnutrition is a prevalent issue among hospitalized individuals. What is it commonly associated with?

• A. Decreased health care expenses
• B. Elevated blood pressure
• C. Decreased mortality rates
• D. A compromised immune system

Correct answer: D

Rationale: Malnutrition is often associated with a weakened immune system. This is because when the body is not sufficiently nourished, it lacks the necessary nutrients to maintain a well-functioning immune system, making patients more vulnerable to infections and other health complications. This can potentially increase mortality rates and prolong hospital stays, contrary to choice C. Choices A and B are incorrect as malnutrition does not lead to decreased health care costs or high blood pressure. In fact, it may increase health care costs due to the potential for increased complications and extended hospital stays.

5. What nursing diagnosis would be most appropriate for a patient with heart failure?

• A. risk for infection
• B. fluid volume excess
• C. impaired body temperature
• D. ineffective airway clearance

Correct answer: B

Rationale: The most appropriate nursing diagnosis for a patient with heart failure is 'fluid volume excess.' In heart failure, the heart's reduced pumping ability leads to fluid retention, causing an excess of fluid in the body. This can result in symptoms such as edema, shortness of breath, and weight gain. 'Risk for infection,' 'impaired body temperature,' and 'ineffective airway clearance' are not the most appropriate nursing diagnoses for a patient with heart failure as they do not directly relate to the pathophysiology and common issues seen in heart failure patients.
