Nursing Elites

1. In growing children, growth hormone deficiency results in short stature and very slow growth rates. Short stature may result from which of the following?

• A. Anterior pituitary gland hypofunction
• B. Posterior pituitary gland hyperfunction
• C. Parathyroid gland hyperfunction
• D. Thyroid gland hyperfunction

Correct answer: A

Rationale: Short stature in growing children can result from anterior pituitary gland hypofunction, which leads to growth hormone deficiency. The anterior pituitary gland plays a crucial role in stimulating the release of growth hormone, and when it is underactive (hypofunction), insufficient growth hormone is produced, resulting in short stature and slow growth rates.

2. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

3. The healthcare provider is teaching a new mother how to care for her newborn's umbilical cord. Which instruction should be included?

• A. Keep the cord dry and exposed to air
• B. Clean the cord with alcohol at every diaper change
• C. Cover the cord with a sterile dressing
• D. Submerge the cord in water during baths

Correct answer: A

Rationale: Keeping the umbilical cord dry and exposed to air is the correct instruction because it promotes faster healing. Moisture can delay the healing process and increase the risk of infection. Cleaning the cord with alcohol at every diaper change or covering it with a sterile dressing can actually impede the healing process by preventing airflow. Submerging the cord in water during baths is not recommended as it can introduce moisture and increase the risk of infection.

4. A 4-year-old boy ingested an unknown quantity of drain cleaner. He is alert, has a patent airway, and has adequate breathing. You should:

• A. administer 1 g/kg of activated charcoal.
• B. give 15 mL of ipecac and contact medical control.
• C. contact poison control and give him oxygen.
• D. give oxygen and perform a head-to-toe exam.

Correct answer: C

Rationale: When a child ingests a harmful substance like drain cleaner and remains alert with a patent airway and adequate breathing, the initial steps involve contacting poison control to guide further management. In this scenario, providing oxygen to support respiratory function is essential until definitive care is established. Activated charcoal and ipecac are not recommended in the management of ingested caustic substances like drain cleaner. Performing a head-to-toe exam can wait until the child's immediate respiratory needs are addressed and the poison control center has provided guidance on further management.

5. When educating the parents of a child diagnosed with hypothyroidism, the nurse mentions that the child should avoid goitrogens. Which of the following will the nurse mention as an example?

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

Correct answer: C

Rationale: Cabbage is an example of a goitrogen. Goitrogens are substances that interfere with the normal function of the thyroid gland by inhibiting iodine uptake. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contain compounds that can have this effect and should be consumed in moderation by individuals with hypothyroidism to prevent worsening of their condition.
