1. What is the first sign of puberty in boys?
- A. Enlargement of testes
- B. Decreased levels of testosterone
- C. Voice deepening
- D. Pubic hair
Correct answer: A
Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.
2. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)
- A. It is ready to be used immediately.
- B. All below
- C. There is less restriction of activity with a fistula.
- D. It produces dilation and thickening of the superficial vessels.
Correct answer: A
Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.
3. The LPN is assessing for fontanels on the head of a 6-month-old. Which fontanel is expected to still be present?
- A. Posterior
- B. Anterior
- C. Sphenoid
- D. Lambdoid
Correct answer: B
Rationale: The correct answer is B: Anterior. The anterior fontanel usually remains open until about 12-18 months of age, while the posterior fontanel closes by 2-3 months. Choices A, C, and D are incorrect as the posterior fontanel closes by 2-3 months of age, and the sphenoid and lambdoid fontanels are not typically assessed in routine infant head examinations.
4. The nurse is teaching a parent with a 2-month-old infant who has been diagnosed with colic about ways to relieve colic. Which statement by the parent indicates the need for additional teaching?
- A. I should let my infant cry for at least 30 minutes before I respond.
- B. I will swaddle my infant tightly with a soft blanket.
- C. I should massage my infant's abdomen whenever possible.
- D. I will place my infant in an upright seat after feeding.
Correct answer: A
Rationale: Letting an infant cry for prolonged periods can exacerbate colic and increase the infant's distress. It is better to respond promptly to soothe the baby. Other methods like swaddling, gentle massage, and keeping the infant upright can help relieve colic symptoms.
5. 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.
