1. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

2. A healthcare professional is screening patients for immunizations. Which of the following is not a contraindication for immunization?

• A. Seizures
• B. Fever lasting more than 3 days
• C. Malignancy within the past 3 months
• D. Illness lasting more than 6 months

Correct answer: D

Rationale: The correct answer is D, 'Illness lasting more than 6 months.' Chronic conditions lasting more than 6 months are not considered a contraindication for immunization. Choice A, 'Seizures,' can be a contraindication in certain situations, especially if linked to a specific vaccine component. Choice B, 'Fever lasting more than 3 days,' can be a temporary precaution but not a general contraindication. Choice C, 'Malignancy within the past 3 months,' is a contraindication due to the compromised immune system in cancer patients.

3. Which behavior by a new nurse would indicate to the charge nurse that this nurse is following standard precautions?

• A. Wearing clean gloves while performing a heel stick on an infant
• B. Wearing the same gloves for assessments of clients in the same room
• C. Wearing sterile gloves when changing the urine bag and nasogastric canister of an infected client
• D. Donning a gown when responding to a request by the family to check the IV pump on a client with rotavirus

Correct answer: A

Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.

4. A nurse working in a pediatric clinic observes the following situations. Which of the following may indicate a delayed child to the nurse?

• A. A 12-month-old that does not 'cruise'.
• B. An 8-month-old that can sit upright unsupported.
• C. A 6-month-old that is rolling prone to supine.
• D. A 3-month-old that does not roll supine to prone.

Correct answer: A

Rationale: The correct answer is 'A 12-month-old that does not 'cruise''. At 12 months, a child should at least be 'cruising' (holding on to objects to walk), which is considered pre-walking. The other choices describe age-appropriate developmental milestones: sitting upright unsupported by 8 months, rolling prone to supine by 6 months, and rolling supine to prone by 3 months. Not 'cruising' at 12 months may indicate a delay in motor skills development.

5. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.
