Nursing Elites

1. A patient has been diagnosed with hypothyroidism; the nurse tells the patient not to eat goitrogens. Which of the following is an example of a goitrogen?

• A. Orange
• B. Tomatoes
• C. Cabbage
• D. Grapes

Correct answer: C

Rationale: Cabbage is an example of a goitrogen. Goitrogens are substances that can interfere with thyroid function by inhibiting the uptake of iodine. Cabbage contains compounds that can have this effect and should be consumed in moderation by individuals with hypothyroidism.

2. When is a newborn considered premature?

• A. Weighs less than 6.5 pounds.
• B. Is born to a heroin-addicted mother.
• C. Is born before 37 weeks gestation.
• D. Has meconium in or around its mouth.

Correct answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

3. Which of the following are clinical types of diarrhoea EXCEPT?

• A. Acute watery
• B. Bloody diarrhoea
• C. Persistent diarrhoea
• D. Secretory diarrhoea

Correct answer: D

Rationale: Secretory diarrhoea is not a clinical type but a distinct mechanism of diarrhoea characterized by increased electrolyte secretion. Acute watery, bloody, and persistent diarrhoea are recognized clinical types associated with different underlying causes and pathophysiologies. Acute watery diarrhoea is common in infectious gastroenteritis, bloody diarrhoea can be caused by inflammatory conditions or infections, and persistent diarrhoea typically lasts for more than 14 days due to various reasons like infections, malabsorption, or inflammatory bowel diseases.

4. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

5. Which of the following techniques represents the MOST appropriate method of opening the airway of an infant with no suspected neck injury?

• A. Perform the technique as you would for an older child or adult.
• B. Lift up the chin and hyperextend the neck.
• C. Gently lift the chin while maintaining slight flexion of the neck.
• D. Tilt the head back without hyperextending the neck.

Correct answer: D

Rationale: Tilting the head back without hyperextending the neck is the safest way to open an infant's airway. Hyperextending the neck can potentially cause harm to the infant, making option D the most appropriate method for opening an infant's airway without suspected neck injury.
