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. A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?

• A. antibody to hepatitis D (anti-HDV).
• B. hepatitis B surface antigen (HBsAg).
• C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
• D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).

Correct answer: D

Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

3. A 3-year-old child was brought to the pediatric clinic after the sudden onset of findings that include irritability, thick muffled voice, croaking on inspiration, being hot to the touch, sitting leaning forward, tongue protruding, drooling, and suprasternal retractions. What should the nurse do first?

• A. Prepare the child for an X-ray of the upper airways
• B. Examine the child's throat
• C. Collect a sputum specimen
• D. Notify the healthcare provider of the child's status

Correct answer: D

Rationale: The correct initial action is to notify the healthcare provider of the child's status. The presenting symptoms described, such as irritability, thick muffled voice, croaking on inspiration, being hot to the touch, sitting leaning forward, tongue protruding, drooling, and suprasternal retractions, are indicative of epiglottitis, a potentially life-threatening condition. Immediate medical attention is crucial in such cases. While preparing for an X-ray or examining the throat may be necessary, the priority is to ensure prompt evaluation and intervention by the healthcare provider. Collecting a sputum specimen is not relevant in this situation and would cause unnecessary delay. Therefore, the nurse should prioritize communication with the healthcare provider to expedite appropriate management and treatment.

4. Which of the following techniques can help to prevent skin irritation or breakdown around a tracheostomy site?

• A. Manage secretions by providing suction on a regular basis
• B. Cleanse the site daily with a mixture of povidone-iodine and water
• C. Avoid using tube ties to secure the tube
• D. None of the above

Correct answer: A

Rationale: Excess secretions from the tracheostomy tube can collect near the stomal opening and cause skin breakdown. Management of secretions through regular suctioning will keep the area clean and dry, minimizing skin irritation. Choice B, cleansing the site daily with povidone-iodine and water, is incorrect as it may lead to skin irritation due to the harshness of povidone-iodine. Choice C, avoiding tube ties to secure the tube, is also incorrect as securing the tube is essential for stability. Choice D, 'None of the above,' is incorrect as managing secretions through suctioning is crucial in preventing skin irritation.

5. A client is being assessed for risks of a pressure ulcer by a healthcare professional. What is the best description of what may be found with an early pressure ulcer in an African American client?

• A. Skin has a purple/bluish color
• B. Capillary refill is 1 second
• C. Skin appears blanched at the pressure site
• D. Tenting appears when checking skin turgor

Correct answer: A

Rationale: When assessing for signs of developing pressure ulcers in a client with dark skin, traditional signs like blanching may not be evident. In individuals with darker skin tones, the skin of an early pressure ulcer may present with a purple or bluish hue. This discoloration can be a crucial indicator of compromised circulation and tissue damage. Capillary refill, blanching, and tenting are more commonly used in the assessment of skin integrity and hydration levels but may not be as reliable in individuals with darker skin tones, making the purple/bluish color a key finding in this context.
