1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. The nurse is caring for a post-surgical client at risk for developing deep vein thrombosis. Which intervention is an effective preventive measure?

• A. Use elastic stockings continuously
• B. Encourage range of motion and ambulation
• C. Massage the legs twice daily
• D. Place pillows under the knees

Correct answer: B

Rationale: Encouraging range of motion and ambulation is an effective preventive measure for deep vein thrombosis in post-surgical clients. Mobility helps improve blood circulation, reducing the risk of clot formation. Elastic stockings help prevent blood pooling and clotting in the legs by providing external pressure to support venous return. Massaging the legs twice daily may help with circulation but is not as effective as promoting movement and ambulation. Placing pillows under the knees is a comfort measure and does not directly address the prevention of deep vein thrombosis.

3. The parents of a newborn with a cleft lip are concerned and ask the nurse when the lip will be repaired. With which statement should the nurse respond?

• A. Cleft lip cannot be repaired.
• B. Cleft-lip repair is usually performed by 6 months of age.
• C. Cleft-lip repair is usually performed during the first months of life.
• D. Cleft-lip repair is usually performed between 6 months and 2 years.

Correct answer: C

Rationale: Cleft-lip repair is typically performed during the first few months of life to address functional and cosmetic concerns at an early stage. Early repair can enhance bonding and facilitate feeding. While revisions may be necessary later on, addressing the cleft lip early is essential. Option A is incorrect as cleft lip repair is a common surgical procedure. Option B is incorrect as repair is typically done earlier than 6 months for better outcomes. Option D is incorrect as the usual timing for repair is within the first months of life, not between 6 months and 2 years.

4. Why is it important to genotype HCV before initiating drug therapy?

• A. Side effects of nucleotide analogs
• B. Measures for improving the appetite
• C. Ways to increase activity and exercise
• D. Administering alpha-interferon (Intron A)

Correct answer: B

Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.

5. Which assessment finding would the nurse need to report most quickly to the health care provider regarding a patient with acute pancreatitis?

• A. Nausea and vomiting
• B. Hypotonic bowel sounds
• C. Abdominal tenderness and guarding
• D. Muscle twitching and finger numbness

Correct answer: D

Rationale: The correct answer is muscle twitching and finger numbness. These symptoms indicate hypocalcemia, which can lead to tetany if not promptly addressed with calcium gluconate administration. Nausea and vomiting, hypotonic bowel sounds, and abdominal tenderness and guarding are important findings in acute pancreatitis but do not require the same urgent intervention as hypocalcemia to prevent potential severe complications.
