Nursing Elites

1. 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.

2. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

3. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?

• A. Bronchodilation, muscle relaxation, and decreased mucus production
• B. Air trapping and hypo-inflation of the alveoli
• C. Air trapping and decreased blood flow to the upper airway
• D. Bronchoconstriction, airway inflammation, and excess mucus production

Correct answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

4. The caregiver asks why the 6-month-old infant needs to have solid foods when breast milk is such a good source of nutrition. What would be the best response by the nurse?

• A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately.
• B. The extrusion reflex must be developed and feeding solid foods will help the infant to develop this reflex.
• C. Breastfeeding will become painful when the infant gets more teeth, so the infant needs to eat solid foods.
• D. By this age the infant becomes interested in trying new skills.

Correct answer: A

Rationale: The correct response is A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately. Choice B is incorrect because the extrusion reflex is related to the tongue-thrust reflex, not the nutritional needs of the infant. Choice C is incorrect as breastfeeding does not become painful when the infant gets more teeth, and it is not a reason for introducing solid foods. Choice D is incorrect as the infant's interest in trying new skills is not a primary reason for introducing solid foods at this age.

5. A new mom is ready to introduce solid foods to her infant. Which food would you recommend starting with?

• A. Meat
• B. Rice cereal
• C. Fruits
• D. Vegetables

Correct answer: B

Rationale: The correct answer is B: Rice cereal. Rice cereal is typically the first solid food introduced to infants because it is easy to digest and unlikely to cause an allergic reaction. Starting with rice cereal helps assess the baby's readiness for solid foods and reduces the risk of allergic responses. Choice A (Meat) is not recommended as the initial solid food due to its higher allergenic potential. Choices C (Fruits) and D (Vegetables) are also not usually recommended as the first solid food, as they may be more challenging for infants to digest compared to rice cereal.
