1. 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.

2. The nurse is teaching the mother of a 9-month-old infant about administering liquid iron preparation. Which information should be included in the teaching?

• A. Adequate dosage will turn the stools a tarry, black color.
• B. Give Vitamin D to enhance absorption.
• C. Allow the liquid iron to mix with saliva before swallowing.
• D. Give the liquid iron with meals.

Correct answer: A

Rationale: The correct answer is A. Iron supplements can cause stools to turn black, which is a normal and harmless side effect. Iron is best absorbed on an empty stomach, although it can be given with food if gastrointestinal upset occurs. Vitamin C, not D, enhances iron absorption. Choice B is incorrect because Vitamin C enhances iron absorption, not Vitamin D. Choice C is incorrect as there is no need to mix liquid iron with saliva before swallowing. Choice D is incorrect because iron is best absorbed on an empty stomach.

3. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

4. The nurse is caring for an infant who was born 24 hr ago to a mother who received no prenatal care. The infant is a poor feeder but sucks avidly on his hands. Clinical manifestations also include hyperactive reflexes, tremors, sneezing, and a high-pitched shrill cry. What does the nurse consider as a possible diagnosis for this infant?

• A. Seizure disorder
• B. Narcotic withdrawal
• C. Placental insufficiency
• D. Meconium aspiration syndrome

Correct answer: B

Rationale: In this case, the infant's symptoms are consistent with narcotic withdrawal. Infants exposed to drugs in utero may display withdrawal symptoms starting around 12 to 24 hours post-birth. The presentation often includes hyperactive reflexes, tremors, sneezing, high-pitched shrill cry, poor feeding, and sucking avidly on hands. Signs such as loose stools, tachycardia, fever, projectile vomiting, sneezing, and generalized sweating are common. These symptoms are not indicative of a seizure disorder. Placental insufficiency typically leads to a small-for-gestational-age child, which is not mentioned in the scenario. Meconium aspiration syndrome primarily presents with respiratory distress, not the symptoms described in this case.

5. 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.
