Nursing Elites

1. Which information about hemophilia will the nurse include in the teaching plan for the parents of a child diagnosed with hemophilia?

• A. Autosomal dominant disorder in which the blood clotting factors are deficient.
• B. X-linked recessive inherited disorder in which blood clotting factors are deficient.
• C. X-linked recessive inherited disorder involving decreased platelets causing prolonged bleeding.
• D. Autosomal recessive disorder in which the blood clotting factors are deficient.

Correct answer: B

Rationale: The correct answer is B: Hemophilia is an X-linked recessive disorder, primarily affecting males and passed from mothers to sons. It involves a deficiency in clotting factors, leading to prolonged bleeding. Choice A is incorrect as hemophilia is not autosomal dominant. Choice C is incorrect as hemophilia does not involve platelets. Choice D is incorrect as hemophilia is not autosomal recessive.

2. The nurse is caring for a child with acute renal failure. What laboratory findings should the nurse expect to find? (Select all that apply.)

• A. Hyponatremia
• B. Hyperkalemia
• C. All are applicable
• D. Elevated blood urea nitrogen level

Correct answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

3. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

4. 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.

5. A parent brings their 4-year-old child for a check-up. Which finding would concern the nurse?

• A. Ectomorphic body type
• B. Resting pulse rate of 120
• C. Weight gain of 5 lb (2.27 kg) in the past year
• D. No increase in appetite compared with that in toddler years

Correct answer: B

Rationale: A resting pulse rate of 120 is elevated for a 4-year-old and may indicate an underlying issue that needs further investigation. An ectomorphic body type is a body shape and not typically a cause for concern. Weight gain within normal limits and no significant change in appetite are generally positive findings in a growing child.
