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 performing an oral examination on a preschool child. Which strategies should the nurse use to encourage the child to open the mouth for the examination? (Select all that apply.)

• A. Lightly brush the palate with a cotton swab
• B. Perform the examination in front of a mirror
• C. Let the child examine someone else's mouth first
• D. All of the above

Correct answer: D

Rationale: Using a cotton swab, allowing the child to observe, and demonstrating on someone else are effective ways to encourage a preschooler to open their mouth for examination.

3. What does the American Academy of Pediatrics recommend as the best form of infant nutrition?

• A. Exclusive breastfeeding until 1 year of age
• B. Exclusive breastfeeding until 6 months of age
• C. Commercially prepared infant formula until 1 year of age
• D. Commercially prepared infant formula until 4 to 6 months of age

Correct answer: A

Rationale: The American Academy of Pediatrics advocates for exclusive breastfeeding until 1 year of age as the best form of infant nutrition. Breastfeeding for the first year of life provides optimal nutrition and benefits for the infant. Exclusive breastfeeding until 6 months of age is not in line with the AAP's recommendation for a full year. While commercially prepared infant formula is an alternative if breastfeeding is not possible, it is not the preferred choice according to AAP guidelines. The recommendation for commercial infant formula until 1 year of age is not in line with the AAP's stance on the benefits of extended breastfeeding.

4. Which assessment findings should the nurse expect in a child with sickle cell anemia experiencing an acute vaso-occlusive crisis?

• A. Circulatory collapse, hypovolemia
• B. Cardiomegaly, systolic murmur
• C. Hepatomegaly, intrahepatic cholestasis
• D. Painful swelling of joints in hands and feet, tissue engorgement

Correct answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia are characterized by painful swelling of the joints in the hands and feet (hand-foot syndrome) and tissue engorgement due to the obstruction of blood flow by sickled cells. Choices A, B, and C are incorrect because circulatory collapse, hypovolemia, cardiomegaly, systolic murmur, hepatomegaly, and intrahepatic cholestasis are not typically associated with an acute vaso-occlusive crisis in sickle cell anemia.

5. What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.
