1. Pertussis vaccination should begin at which age?

• A. Birth
• B. 2 months
• C. 6 months
• D. 12 months

Correct answer: B

Rationale: The DTaP vaccine, which includes pertussis, is typically started at 2 months of age as part of the recommended immunization schedule.

2. What does the Hib conjugate vaccine protect against?

• A. Bacterial meningitis
• B. Epiglottitis
• C. Bacterial pneumonia
• D. All Correct

Correct answer: D

Rationale: The Hib conjugate vaccine is crucial for protecting children from several severe infections caused by Haemophilus influenzae type b, including bacterial meningitis, epiglottitis, bacterial pneumonia, septic arthritis, and sepsis. Therefore, all the provided options are correct. Bacterial meningitis, epiglottitis, and bacterial pneumonia are serious conditions that the Hib vaccine effectively prevents, making choice D the correct answer. Choices A, B, and C are incorrect when considered individually as the Hib vaccine does not protect against only one specific infection; rather, it provides immunity against multiple diseases caused by Haemophilus influenzae type b.

3. A child has a central venous access device for intravenous (IV) fluid administration. A blood sample is needed for a complete blood count, hemogram, and electrolytes. What is the appropriate procedure to implement for this blood sample?

• A. Perform a new venipuncture to obtain the blood sample.
• B. Interrupt the IV fluid and withdraw the blood sample needed.
• C. Withdraw a blood sample equal to the amount of fluid in the device, discard, and then withdraw the sample needed.
• D. Flush the line and central venous device with saline and then aspirate the required amount of blood for the sample.

Correct answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

4. Where would nonpathologic cyanosis normally be present in the newborn shortly after birth?

• A. Feet and hands
• B. Bridge of nose
• C. Circumoral area
• D. Mucous membranes

Correct answer: A

Rationale: Nonpathologic cyanosis in newborns shortly after birth is typically present in the feet and hands, known as acrocyanosis. This is a normal finding due to the immature peripheral circulation in newborns. Cyanosis of the bridge of the nose, circumoral area, and mucous membranes indicates generalized cyanosis, which suggests a potential underlying distress or major abnormality. Therefore, choice A is correct as it describes the expected location for nonpathologic cyanosis in newborns, while choices B, C, and D represent areas associated with abnormal cyanosis.

5. A child with pyloric stenosis is having excessive vomiting. The nurse should assess for what potential complication?

• A. Hyperkalemia
• B. Hyperchloremia
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: D

Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.
