Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. The parent of an 8.2-kg (18-lb) 9-month-old infant is borrowing a federally approved car seat from the clinic. The nurse should explain that the safest way to put in the car seat is what?

• A. Front facing in back seat
• B. Rear facing in back seat
• C. Front facing in front seat with air bag on passenger side
• D. Rear facing in front seat if an air bag is on the passenger side

Correct answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.

3. Nurses should be alert for increased fluid requirements in which circumstance?

• A. Fever
• B. Mechanical ventilation
• C. Congestive heart failure
• D. Increased intracranial pressure

Correct answer: A

Rationale: Fever increases metabolic rate, leading to insensible water loss, thus requiring increased fluid intake. Mechanical ventilation, CHF, and increased intracranial pressure generally require fluid restriction rather than increased fluid intake.

4. The nurse is preparing to admit a 7-year-old child with Crohn disease. What clinical manifestations should the nurse expect to observe?

• A. Pain is common.
• B. Weight loss is severe.
• C. All are correct.
• D. Diarrhea is moderate to severe.

Correct answer: C

Rationale: The correct answer is C because Crohn's disease commonly presents with pain, severe weight loss, and moderate to severe diarrhea in affected individuals. Therefore, all the manifestations listed are typically observed in patients with Crohn's disease. Choice A alone is not sufficient as weight loss and diarrhea are also prominent symptoms. Choice B is incorrect as it only mentions weight loss, omitting other common manifestations. Choice D is also incorrect as it does not cover the full range of expected clinical signs in Crohn's disease.

5. What is the first sign of puberty in girls?

• A. Acne
• B. Hair growth in the pubic area and underarms
• C. Thelarche
• D. Menarche

Correct answer: C

Rationale: The correct answer is C, Thelarche. Thelarche refers to the onset of breast development, which is typically the first sign of puberty in girls. This occurs before menarche (the first menstrual period). Choices A and B, acne and hair growth in the pubic area and underarms, are not the first signs of puberty in girls. While acne can be a common occurrence during puberty, it usually appears after other physical changes. Hair growth in the pubic area and underarms also occurs later in the puberty process.
