Nursing Elites

1. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.

2. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

3. Chest x-ray was ordered after thoracentesis. When your client asks what is the reason for another chest x-ray, you will explain:

• A. to rule out pneumothorax
• B. to rule out any possible perforation
• C. to decongest
• D. to rule out any foreign body

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. A client with celiac disease should avoid which of the following?

• A. Quinoa
• B. Barley
• C. Rice
• D. Oats

Correct answer: B

Rationale: The correct answer is B: Barley. Barley contains gluten, which is harmful to individuals with celiac disease. Gluten triggers an immune response in people with celiac disease, damaging the lining of the small intestine. Choices A, C, and D (Quinoa, Rice, and Oats) are gluten-free and safe for individuals with celiac disease to consume.

5. What characterizes Obsessive Compulsive Disorder?

• A. Uncontrollable impulse to perform an act or ritual repeatedly
• B. Persistent thoughts and behavior
• C. Recurring unwanted and disturbing thoughts
• D. Pathological persistence of unwilled thoughts

Correct answer: A

Rationale: Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.
