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. After reviewing the health and dental histories, the dental hygienist has adequate information to begin dietary counseling with the patient. Providing a standardized, low-carbohydrate menu is sufficient for most patients with a high caries rate.

• 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: B

Rationale: Both statements are false. Dietary counseling should be personalized, and a standardized low-carbohydrate menu is not sufficient for all patients.

3. When a nurse signs a consent form, which ethical principle is being observed regarding the patient?

• A. Autonomy
• B. Justice
• C. Accountability
• D. Beneficence

Correct answer: A

Rationale: The correct answer is 'Autonomy'. Autonomy refers to the patient's right to make their own decisions, which is being honored when a nurse signs a consent form. While beneficence (Choice D) is an important ethical principle that involves acting in the patient's best interest, it is not what is being primarily observed in this instance. Justice (Choice B) refers to fairness and equal treatment and is not specifically relevant to this scenario. Accountability (Choice C) pertains to being answerable for one's actions and decisions, but again, it is not the principle directly observed in this situation. Therefore, when a nurse signs a consent form, it is the principle of autonomy that is being observed.

4. Each statement is true of rickets, except one. Which is the exception?

• A. Rickets is being diagnosed more frequently in the United States.
• B. Rickets is caused by vitamin C deficiency.
• C. Tachetic deformities such as bow legs or knock-knees develop.
• D. A narrow and distorted chest occurs.

Correct answer: B

Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.

5. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?

• A. White Blood Cells 5,200/mm³
• B. Hemoglobin 14 g/dL
• C. Magnesium 1.6 mg/dL
• D. Potassium 3.2 mEq/L

Correct answer: D

Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.
