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. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

• A. The DRIs replace the older recommended daily allowances.
• B. Current DRIs attempt to estimate required nutrients to improve long-term health.
• C. DRIs specifically address individuals whose requirements are affected by a disease state.
• D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients.

Correct answer: C

Rationale: The correct answer is C. DRIs do not specifically address individuals with disease states; they are intended for the general healthy population. Choice A is correct because DRIs indeed replace the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate required nutrients to enhance long-term health. Choice D is accurate as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

3. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:

• A. Percussion uses only one hand, while vibration uses both hands
• B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
• C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
• D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation

Correct answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.

4. During the acute phase of a burn, the priority nursing intervention in caring for this client is:

• A. Prevention of infection
• B. Pain management
• C. Prevention of bleeding
• D. Fluid resuscitation

Correct answer: D

Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.

5. A client who is experiencing dumping syndrome following gastric surgery is receiving education from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should drink additional fluids with my meals.
• B. I should eat high-fiber snacks between meals.
• C. I should eat a protein source with each meal.
• D. I can have caffeinated beverages in small amounts.

Correct answer: C

Rationale: The correct answer is C. Eating a protein source with each meal can help manage dumping syndrome by slowing gastric emptying and reducing symptoms. This choice is the most appropriate as it directly addresses a key dietary recommendation for dumping syndrome. Choices A, B, and D are incorrect because drinking additional fluids with meals, eating high-fiber snacks between meals, and consuming caffeinated beverages can exacerbate dumping syndrome symptoms by increasing gastric emptying and worsening the condition.
