Nursing Elites

1. What is the main function of proteins in the body?

• A. They provide structural components for the body.
• B. They assist in the absorption of vitamins.
• C. They help with the transport of nutrients in the blood.
• D. They help maintain fluid balance in the body.

Correct answer: A

Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).

2. Parents of a 6-month-old child, diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What should the nurse say?

• A. Are you sure your child has iron deficiency anemia?
• B. Maternal stores of iron are depleted at about 6 months.
• C. This anemia is caused by blood loss.
• D. The child may not have had it for a long time.

Correct answer: B

Rationale: The correct answer is B: 'Maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent around 6 months of age when the infant's iron stores, primarily received from the mother during pregnancy, are depleted. This timing coincides with the introduction of solid foods, which may lack sufficient iron. Choices A, C, and D are incorrect because they do not address the specific reason why iron deficiency anemia is typically diagnosed around 6 months of age.

3. How should a healthcare provider handle a child with a suspected head injury who is showing signs of drowsiness?

• A. Administer pain medication
• B. Perform a full neurological assessment
• C. Allow the child to sleep
• D. Contact a specialist immediately

Correct answer: B

Rationale: When a child with a suspected head injury is showing signs of drowsiness, administering pain medication should not be the first course of action as it may mask important symptoms. Allowing the child to sleep is not recommended as they need to be monitored. Contacting a specialist immediately may delay necessary assessments. Performing a full neurological assessment is the most appropriate action because it helps evaluate the head injury's extent, identify neurological deficits, and guide further intervention or treatment.

4. How should a healthcare provider respond to a parent concerned about their child's sleep pattern?

• A. Recommend a sleep study
• B. Suggest increasing daytime naps
• C. Provide education on sleep hygiene
• D. Advise on medication use

Correct answer: C

Rationale: When a parent expresses concerns about their child's sleep pattern, providing education on sleep hygiene is a beneficial response. Teaching parents about establishing a consistent sleep routine, creating a conducive sleep environment, and promoting healthy sleep habits can help address the child's sleep issues. This empowers the parent to make positive changes that can improve the child's sleep patterns. Recommending a sleep study (Choice A) may be premature and unnecessary without first addressing basic sleep hygiene. Suggesting increasing daytime naps (Choice B) may not always be appropriate and could further disrupt the child's nighttime sleep. Advising on medication use (Choice D) should be considered only after other non-pharmacological approaches have been tried and if deemed necessary by a healthcare provider.

5. Food energy is commonly expressed in kilocalories and in what other unit?

• A. kilojoules
• B. kilograms
• C. kilometers
• D. kilonewtons

Correct answer: A

Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.
