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

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. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

3. The nurse is preparing an airborne infection isolation room for a patient. Which communicable disease does the patient likely have?

Correct answer: A

Rationale: Varicella (chickenpox) is an airborne infectious disease, requiring isolation to prevent the spread of the virus.

4. Pretending a sheet is a cape to mimic a superhero is characteristic of which childhood phenomenon?

Correct answer: B

Rationale: The correct answer is B, symbolic functioning. Symbolic functioning refers to children using objects, actions, or ideas to represent other objects, actions, or ideas. In this scenario, pretending a sheet is a cape to mimic a superhero demonstrates the child's ability to engage in symbolic play. Choice A, artificialism, is incorrect as it refers to the belief that inanimate objects have lifelike qualities. Choice C, critical thinking, does not directly relate to the imaginative play described in the question. Choice D, dramatic play, is close but not as precise as symbolic functioning, which specifically highlights the use of objects to represent something else.

5. A thorough systemic physical assessment is necessary in the extremely low-birth-weight (ELBW) infant to detect what?

Correct answer: C

Rationale: In extremely low-birth-weight (ELBW) infants, a thorough systemic physical assessment is crucial to detect subtle changes that may indicate an underlying problem. These infants are highly vulnerable and may show signs of stress through changes in feeding behavior, activity, color, oxygen saturation, or vital signs. Monitoring weight in ELBW infants primarily reflects genitourinary function rather than fluid retention. Difficulties in maternal-child attachment are important but are usually assessed during parental visits and are not the primary focus of a systemic physical assessment. Changes in the Apgar score are used immediately after birth to assess the transition to extrauterine life and are not as relevant in the following 24 hours to detect ongoing subtle issues.
