1. Which immunization is typically administered at birth?

• A. Hepatitis B
• B. DTaP
• C. MMR
• D. Varicella

Correct answer: A

Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.

2. Which is the leading cause of death in infants younger than 1 year in the United States?

• A. Congenital anomalies
• B. Sudden infant death syndrome
• C. Disorders related to short gestation and low birth weight
• D. Maternal complications specific to the perinatal period

Correct answer: A

Rationale: Congenital anomalies are the leading cause of death in infants younger than 1 year in the United States.

3. An intravenous line is needed in a school-age child. What medication is an appropriate analgesic for use with this patient?

• A. TAC (tetracaine, epinephrine [Adrenalin], cocaine) 15 minutes before the procedure.
• B. A transdermal fentanyl (Duragesic) patch at the site of venipuncture.
• C. EMLA (eutectic mixture of local anesthetics) immediately before the procedure.
• D. LMX (4% liposomal lidocaine cream) 30 minutes before the procedure.

Correct answer: D

Rationale: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.

4. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

5. What is an approximate method of estimating output for a child who is not toilet trained?

• A. Have parents estimate output.
• B. Weigh diapers after each void.
• C. Place a urine collection device on the child.
• D. Have the child sit on a potty chair 30 minutes after eating.

Correct answer: B

Rationale: Weighing diapers is the most accurate way to estimate urine output in a child who is not toilet trained. This method provides a measurable and reliable estimate of fluid output.
